title: Study of precious metals coprecipitation with manganese hydroxide and recovery of gold nanoparticles from computer microporcessor scrap

description: Recovery of gold (Au), platinum (Pt) and palladium (Pd) by coprecipitation with Mn(OH)₂ and their selective separation were investigated to develop an alternative method for recovery of precious metals from electronic wastes. It was found from the study that at pH 9, room temperature, nearly 99% of either Au or Pd was coprecipitated with Mn(OH)₂, while only 40% of Pt was coprecipitated after 24 hours. However, the coprecipitation of Pt was enhanced up to 90% within 24 hours when Pt(IV) coexisted with Au(III) and Mn(II) in the initial solution having Au:Pt:Mn mole ratio of 6:1:10. Au in coprecipitates was reduced to metallic Au (Au(0)) nanoparticles, which is considered to be caused by electron transfer through Au-O-Mn bonding, whereas Pt(IV) and Pd(II) were not reduced to metallic state. It is considered that Pt(IV) and Pd(II) were entrapped or incorporated into MnO2 structure instead of adsorption on Mn(OH)₂ surface like Au. The existence of Au nanoparticles was confirmed by its solubility in dilute HCl solution and TEM analysis, and coprecipitated Au nanoparticles exhibited catalytic ability for CO oxidation at the half conversion temperature (T½) of 80℃. It was also found that the coprecipitated Au and Pd can be selectively separated from coprecipitated Pt by 0.1 mol dm⁻³ HCl dissolution. Results of the study were then applied to recover Au from CPU microprocessor scrap composed of various metals by coprecipitation with Mn(OH)₂. It was found that Au can selectively separated from the sample solution by coprecipitation with Fe(OH)₃ at pH 4 as Au(III) complexes. The Au-Fe coprecipitate was dissolved in 0.01 mol dm⁻³ HCl, and then MnCl₂ solution was added to the Au-Fe solution at Au:Mn mole ratio of 6:10 to achieve up to 81% Au recovered as metallic Au in Fe(OH)₃ and Mn(OH)₂ coprecipitates, or metallic Au supported on manganese and iron oxides surfaces.

title: Decentralizing Indonesia : the problem of creating new local government units

description: This thesis studies one particular aspect of Indonesian decentralization, the creation of new units of sub-national government (known as ‘pemekaran’) and attempts to identify whether it strengthens or weakens the decentralization process. Since decentralization began in 1999, over 150 new districts have been created and these have come under increasing scrutiny for their alleged failure to contribute any significant improvement either governance or service delivery. These criticisms have also been used as to argue for a recentralization of certain powers, thus undermining the decentralization process. This paper identifies the underlying motivations behind the creation of new units in North Sumatra, Papua and West Irian Jaya provinces and analyzes the ability of new districts in the above provinces to efficiently deliver two key services, health and education. The research is based upon secondary sources, primarily book and internet research. The findings suggest that the new districts do not appear to suffer from a lack of spending or service availability in comparison with the old districts and can actually enhance health and education services. Any service improvements though must be weighed against the costs of the new districts as they exacerbate existing inefficiencies in both the health and education systems and represent a significant financial and administrative burden upon the central government. The new districts can therefore be said to have both positive and negative impacts, and their overall contribution to the process will become more evident as the process of decentralization continues to develop in Indonesia.

title: Preparation of Fe catalyst coated on activated carbon for decomposition of aqueous phenol in three-phase fluidized bed reactor

description: A lab-scale three-phase fluidized-bed reactor was used for removal of aqueous phenol by adsorption and decomposition. The gas, liquid and solid phases were air bubbles with or without ozone, aqueous phenol, and granular activated carbon (AC) with and without Fe on AC, respectively. Both the gas flow and liquid recirculation rate were controlled at 1 L.min-1 and the catalyst loading was 5 g per batch. The experiments were carried out using 2 L of 10 ppm phenol solution. Some intermediate products such as hydroquinone (HQ) and catechol (CC) were also detected but they were eventually decomposed to carbon dioxide and H2O. First, two types of AC (AC1 and AC2) with BET surface areas of 1,106 and 1,150 m2.g-1 and average pore diameters of 2.3 and 1.7 nm, respectively, were compared. It was found that AC1 with more mesopores removed the intermediate products better than AC2 with more micopores. Since both AC removed phenol with the same efficiency, AC1 was selected for use in all subsequent experiments. Comparison of the phenol and TOC removal efficiencies were made for the following cases: 1) only O3 from pure O2 or air, 2) only AC, 3) only Fe/AC, 4 and 5) O3 in combination with cases 2) and 3), respectively. The sequence of decreasing phenol removal efficiency was as follows: 5) (100% at 15 min) &gt; 4) (100% at 30 min) &gt; 3) (100% at 45 min) ≈ 2) (100% at 45 min) &gt; 1) from pure O2 (100% at 90 min) &gt; 1) from air (100% at 150 min). Meanwhile, the sequence of decreasing TOC removal efficiency was as follows: 4) (89% at 150 min) &gt; 5) (83% at 150 min) &gt; 2) (79% at 150 min) &gt; 3) (77% at 150 min) &gt; 1) from pure O2 (70% at 150 min) &gt; 1) from air (negligible removal). In conclusion, the use of AC with O3 from air was a best compromise in terms of TOC removal efficiency and operation costs

title: Detection of carbapenemase genes in acinetobacter baumannii

description: Carbapenems are among the drugs of choice for treatment of multidrug-resistant acinetobacter baumannii infections. However, emergence of carbapenem resistance in A. baumannii has been reported worldwide. The present study identified carbapenemase genes in A. baumannii and investigated the prevalence of carbapenem resistance of the 501 A. baumannii isolated from patients at the King Chulalongkorn Memorial Hospital, Bangkok during January 2004 to August 2007. The minimal inhibitory concentrations (MICs) of imipenem and meropenem were determined by agar dilution. Resistance rates were 82.4% and 81.8% for imipenem and meropenem, respectively. All carbapenem-resistant isolates had carbapenemase activity by modified Hodge test. Metallo- β-lactamases were not detected in any isolate when screened by imipenem-EDTA double-disk synergy test. Screening for carbapenemase genes in the 501 A. baumannii by PCR revealed the presence of blaOXA-23-like, blaOXA-24-like, blaOXA-51-like, and blaOXA-58-like, and the absence of blaIMP-like, and blaVIM-like. All 501 A. baumannii isolates carried the blaOXA-51-like gene. The isolates carrying only blaOXA-51-like were susceptible to carbapenems whereas the isolates carrying blaOXA-51-like together with other blaOXA-like, including blaOXA-23-like, blaOXA-24-like and blaOXA-58-like were resistant to carbapenems. The presence of blaOXA-51-like together with blaOXA-23-like were detected in the majority of carbapenem-resistant A. baumannii isolates (93.2%), suggesting that blaOXA-23-like, plays a major role in carbapenem resistance. DNA sequences of the entire blaOXA-23-like, blaOXA-24-like, blaOXA-51-like and blaOXA-58-like each from 10 representative isolates, were analyzed. The results revealed that the blaOXA-23-like, blaOXA-24-like and blaOXA-58-like, from their 10 representative were blaOXA-23, blaOXA-72 and blaOXA-58 respectively, whereas those of the blaOXA-51-like were blaOXA-68 (5 isolates), blaOXA-66 (2 isolates) and blaOXA-64, blaOXA-67 and a novel blaOXA-51-like (1 isolate each). Nucleotide and amino acid sequences of this novel enzyme showed 99% identity to blaOXA-51 and OXA-51

title: Factors associated with travel related health problems among Japanese travelers in Thailand

description: This cross sectional study conducted from February to March 2009 explored factors associated with travel related health problems among Japanese travelers aged 18 years and above in Thailand. The study involved 394 respondents purposively sampled at the departure lounge of Suvarnabhumi International Airport in Bangkok. A self administered pretested questionnaire was used to collected data. Association between independent and dependent variable was assessed using Chi square test and t- test. Binary logistic regression was used to control for confounding factors. P values of less than or equal to 0.05 were considered statistically significant. Majority of the travelers were male (58.6%), aged less than 24 years (29.7%), with college/undergraduate education level (42.7%), earning less than 3 million yen annually, government/company employees, Buddhists (53.2%), single (52.2%), had stayed for 4 days (62.2%), in urban areas (82.6%), had travelled to Thailand for holiday (84.9%), had travel health insurance (74.7%), had not been vaccinated for the trip (95.4%), did not access pre- travel heath information (64.5%), and did not consult a travel heath clinic before travel (93.9%). Most travelers (80.7%) had high attitude score on travel health but had medium knowledge on travel health (64.4%). Eating street food was the common travel health risky practice (35.5%). Travelers who reported having developed a health problem while in Thailand were 32.1%. Diarrhea/lower abdominal pain (13.8%) was the most common health problem followed by skin symptoms (11.0%), stomach symptoms (7.7%) and respiratory problems (6.4%). Logistic regression showed association between health problems among the travelers and age (p = 0.005), eating street food (p = 0.001), and drinking water (p = 0.001). This study suggests that health problems among Japanese travelers in Thailand are mainly related to food and water consumption with young people being at higher risk. Providing more information about travel health to Japanese travelers, educating them on the risk of street food and unsafe drinking and promoting hygienic practices in food handling among street food vendors in Thailand are recommended.

title: Website Fingerprinting - Last Level Cache Contention Traces

description: Website fingerprinting attacks, which use statistical analysis on network traffic to compromise user privacy, have been shown to be effective even if the traffic is sent over anonymity-preserving networks such as Tor. The classical attack model used to evaluate website fingerprinting attacks assumes an on-path adversary, who can observe all traffic traveling between the user's computer and the secure network. In this work we investigate these attacks under a different attack model, in which the adversary is capable of sending a small amount of malicious JavaScript code to the target user's computer. The malicious code mounts a cache side- channel attack, which exploits the effects of contention on the CPU's cache, to identify other websites being browsed. The effectiveness of this attack scenario has never been systematically analyzed, especially in the open-world model which assumes that the user is visiting a mix of both sensitive and non-sensitive sites. We show that cache website fingerprinting attacks in JavaScript are highly feasible. Specifically, we use machine learning techniques to classify traces of cache activity. Unlike prior works, which try to identify cache conflicts, our work measures the overall occupancy of the last- level cache. We show that our approach achieves high classification accuracy in both the open-world and the closed- world models. We further show that our attack is more resistant than network-based fingerprinting to the effects of response caching, and that our techniques are resilient both to network-based defenses and to side-channel countermeasures introduced to modern browsers as a response to the Spectre attack. To protect against cache-based website fingerprinting, new defense mechanisms must be introduced to privacy-sensitive browsers and websites. We investigate one such mechanism, and show that generating artificial cache activity reduces the effectiveness of the attack and completely eliminates it when used in the Tor Browser.

title: CRCNS.org hc-25

description: Action potentials and local field potentials (LFPs) were simultaneously recorded from the dorsal hippocampus (CA1) and medial prefrontal cortex (mPFC) of nine Long-Evans rats during sleep and behavior. During behavior, the rats explored a rectangular enclosure with two identical objects (spatial object recognition task). Sleep sessions include unperturbed sleep, timed stimulation of motor cortex triggered by hippocampal ripples, and delayed (control) stimulation. Results from the experiments are described in: N. Maingret, G. Girardeau, R. Todorova, M. Goutierre, M. Zugaro (2016). Hippocampo-cortical coupling mediates memory consolidation during sleep. Nature Neuroscience 19(7):959-64. R. Todorova and M. Zugaro (2019). Isolated cortical computations during delta waves supports memory consolidation. Science (in press). The data set includes # sessions, each consisting of pre-task sleep, task, and post-task sleep (~# min sleep sessions). Hippocampal and cortical signals were recorded using sixteen independently movable tetrodes (64 channels). Data include sorted spikes (times, clusters, featres, and full waveforms), LFPs (at 1250 Hz), positions (coordinates of head-mounted LEDs), and experiment descriptions.
