Heterogeneous oxidation of sulfacetamide in aquatic environment using ultrasonic and nano-fenton: Kinetics intermediates and bioassay test

In present study, degradation of sulfacetamide from a synthetic wastewater by sonofenton process using zero valent iron nanoparticles was investigated. The synthesized iron nanoparticles were characterized using transmission electron microscopy (TEM), UV-visible and X-ray diffraction pattern (XRD). The effect of various parameters, such as pH, nZVI dose, H2 O2 concentration and contact time was studied with batch experiments. The removal efficiency of sulfacetamide by US/nZVI/H2 Of process was about 91 for reaction time of 60 min, but less than 27 of chemical oxygen demand (COD) was removed. Kinetics studies showed that the degradation of sulfacetamide fitted well to the pseudo-second-order model. Using the LC/MS device, five intermediate from degradation of sulfacetamide were detected. The toxicity test, using micro toxicity study also showed that the effluent from the sono-Fenton reactor has a lower toxicity than sulfacetamide antibacterial. © 2019 Desalination Publications.

Transparansi Anggaran: suatu Upaya Efisiensi dan Antisipasi Korupsi di Indonesia

Budget transparency is believed to be able to develop an effective, efficient, and corruptionfreeorganization system. Implementing it will enable an organization to erase any unnecessarybudget. A more transparent budget also implies stakeholders' consultation in every stepof budgeting to eliminate all sources of manipulation and corruption. In Indonesia markingup budget by posting some irrelevant and fictive activities is still commonly happening. It hasbeen part of commonly used way to corrupt. Based on these situations, this paper will discusshow budget functions and principles, Islamic base value for budgeting, and how controllingsystem on budget should be implemented in order to efficiently anticipate corruption

Pro dan Kontra Undang-undang Anti Pornografi dan Pornoaksi

It is actually ironically, in one hand Indonesia society talking about the morality of nation, on the other hand, this nation ignore pornography and pornoaction.Instead, Some people refuse the proposed academic manuscript regarding pornography and pornoaction. Apart from the pros and cons toward the act of pornography and pornoaction, pornography and pornoaction denote ophyum in the living of society. According to the writer of the following article, because of majority of Indonesian population are Moslem, so Indonesian Moslem should participate in the discourse of the act. But, how to search for horizon wisely, either in term of culture or the principles of Islam

Pemikiran Ekonomi Islam Abu Yusuf

This paper studies on the islamic economic thought of Abu Yusuf. Broadly speaking there are four things that made Abu Yusuf in the country restructure its economic system in Baghdad during the reign of Caliph Harun al-Rashid. First, replacing the system with a system wazīfah, muqassamah. Second, building the understanding of social flexibility. Third, build political and economic system that is transparent. Fourth, create an autonomous economic system

Ark or park: the need to predict relative effectiveness of ex situ and in situ conservation before attempting captive breeding

1. When species face extinction, captive breeding may be appropriate. However, captive breeding may be unsuccessful, while reducing motivation and resources for in situ conservation and impacting wild source populations. Despite such risks, decisions are generally taken without rigorous evaluation. We develop an individual-based, stochastic population model to evaluate the potential effectiveness of captive-breeding and release programmes, illustrated by the Critically Endangered Ardeotis nigriceps Vigors great Indian bustard. 2. The model was parameterized from a comprehensive review of captive breeding and wild demography of large bustards. To handle uncertainty in the standards of captive-breeding performance that may be achieved we explored four scenarios of programme quality: ‘full-range’ (parameters sampled across the observed range), ‘below-average’, ‘above-average’ and ‘best possible’ (performance observed in exemplary breeding programmes). Results are evaluated examining i) the probability of captive population extirpation within 50 years and ii) numbers of adult females subsequently established in the wild following release, compared to an alternative strategy of in situ conservation without attempting captive breeding. 3. Successful implementation of captive breeding, involving permanent retention of 20 breeding females and release of surplus juveniles, required collection of many wild eggs and consistent ‘best possible’ performance across all aspects of the programme. Under ‘full-range’ and ‘above-average’ scenarios captive population extirpation probabilities were 73–88% % and 23‒51%% respectively, depending on egg collection rates. 4. Although most (73‒92%) ‘best possible’ programmes supported releases, re-establishment of free-living adults also required effective in situ conservation. Incremental implementation of effective conservation measures over the initial 10 years resulted in more free-living adults within 35 years if eggs were left in the wild without attempting captive breeding. 5. Synthesis and applications. For the great Indian bustard Ardeotis nigriceps, rapid implementation of in situ conservation offers a better chance to avoid extinction than captive breeding. Demographic modelling should be used to examine whether captive breeding is likely to bring net benefits to conservation programmes

Thermally isolated Luttinger liquids with noisy Hamiltonians

We study the dynamics of a quantum-coherent thermally isolated Luttinger liquid with noisy Luttinger parameter. To characterize the fluctuations of the absorbed energy in generic noise-driven systems, we first identify two types of energy moments, which can help tease apart the effects of classical (sample-to-sample) and quantum sources of fluctuations. One type of moment captures the total fluctuations due to both sources, while the other one captures the effect of the classical source only. We then demonstrate that in the Luttinger liquid case, the two types of moments agree in the thermodynamic limit, indicating that the classical source dominates. In contrast to equilibrium thermodynamics, in this driven system the relative fluctuations of energy do not decay with the system size. Additionally, we study the deviations of equal-time correlation functions from their ground-state value, and find a simple scaling behavior.Comment: 11 pages, 2 figure

How to find conductance tensors of quantum multi-wire junctions through static calculations: application to an interacting Y-junction

Conductance is related to dynamical correlation functions which can be calculated with \textit{time-dependent} methods. Using boundary conformal field theory, we relate the conductance tensors of quantum junctions of multiple wires to static correlation functions in a finite system. We then propose a general method for determining the conductance through \textit{time-independent} calculations alone. Applying the method to a Y-junction of interacting quantum wires, we numerically verify the theoretical prediction for the conductance of the chiral fixed-point of the Y-junction and then calculate the thus far unknown conductance of its M fixed point with time-independent density matrix renormalization group method.Comment: 4 pages, 2 figures, final published versio
