Fabrication of Copper Inverse Opals for Microscale Liquid Transport in Polycrystalline Porous Media

Author(s): Pham, Quang | Advisor(s): Won, Yoonjin | Abstract: The continually increasing power density of high-performance electronics is bottlenecked by the challenges faced with thermal management requirements for reliable operation. While the traditional convective air-cooling approach is limited in its effectiveness at dissipating high heat fluxes, the use of latent heat in liquid-vapor phase change is an attractive strategy for managing the most aggressive thermal loading demands. Passive two-phase cooling operates by capillary pumping fluid through void spaces within porous metals to transport energy over long distances. The performance of such liquid delivery through porous structures is governed by the pore distribution, porosity, and morphology. Analogous to energy transport in polycrystalline solids, hydraulic transport in polycrystalline porous media is also limited by structural defects and grain boundaries. This work reports on the capillary performances of both single- and polycrystalline microporous copper with varying pore diameters from 300 to 1000 nm. The hydraulic transport through the arrays of interconnected spherical pores is modeled and quantified with experimental wicking measurements, and the influence of grain boundaries on the hydraulic transport in polycrystalline microporous media contributes to the hydraulic resistance presented by the structural defects. By combining multiple pore diameters and systematically layering them, this study creates heterogeneousporous media to emulate the transport within biological systems. The gradient layering of pores enhances the liquid delivery by circumventing grain boundary defects in three dimensions. The fundamental understanding of hydraulic transport physics through porous crystals and boundaries will pave the way for the spatial design of heterogeneous porous materials for future capillary-driven technologies.
First-principles insights on mechanical and electronic properties of TiX (X=C,N) in β-Si3N4 based ceramics

The mechanical and electronic properties of β-Si3N4, TiC-Si3N4 and TiN-Si3N4 ceramics are investigated using density functional theory implemented with GGA/PBE functional. The pristine β-Si3N4 exhibits fracture for a strain of 10%. However, TiC-Si3N4 and TiN-Si3N4 ceramics exhibits fracture for a strain of 20%. The Young’s modulus, shear modulus and bulk modulus of the pristine β-Si3N4, TiC-Si3N4 and TiN-Si3N4 ceramics are reported. TiN-Si3N4 ceramic is found to be the least compressible and hard. The band gap is found to decrease for TiC-Si3N4 and TiN-Si3N4 ceramics compared with the pristine β-Si3N4. The density of states spectrum shows more peak maxima for TiC-Si3N4 and TiN-Si3N4 ceramics rather than β-Si3N4. The finding of the present work gives a clear insight on the mechanical and electronic properties of β-Si3N4, TiC-Si3N4 and TiN-Si3N4 ceramics at the atomistic level.
Beyond ‘the Beamer, the boat and the bach’? A Content Analysis-Based Case Study of New Zealand Innovative Firms

In this paper we will use case studies to seek to understand the dynamic innovation processes at the level of the firm and to explain the apparent 'enigma' between New Zealand's recent innovation performance and economic growth. A text-mining tool, Leximancer, (version 4) was used to analyse the case results, based on content analysis. The case studies reveal that innovation in New Zealand firms can be best described as 'internalised', and the four key factors that affect innovation in New Zealand firms are ‘Product’, ‘Market’, ‘People’ and ‘Money’. New Zealand may be an ideal place for promoting local entrepreneurship, however, many market/technology opportunities cannot be realized in such a small and isolated economy, hence the poor economic performance.
Class discrimination and meritocracy in the labor market: evidence from Chile

This paper studies class discrimination and meritocracy in the Chilean labor market. Employing a dataset rich in productivity and class measures, we find that upper-class professionals earn approximately 50 per cent more than those raised in lower socioeconomic backgrounds. This gap is unrelated to differences in academic performance at university, second language proficiency, postgraduate studies, schools’ academic quality, geographic origin and other standard controls, which suggests some employer discrimination. This gap is larger than gaps reported elsewhere for gender, race and physical appearance. Meritocracy is modest, as the effect of socioeconomic background on earnings outweighs that of academic performance at university.
Implementation and analysis of list mode algorithm

10 In this work we present an innovative algorithm for the recon struction of PET 11 images based on the List-Mode (LM) technique which improves th ir spatial res12 olution compared to results obtained with current MLEM algo rithms. This study 13 appears as a part of a large project with the aim of improving d a nosis in early 14 Alzheimer disease stages by means of a newly developed hybri d PET-MR in15 sert. At the present, Alzheimer is the most relevant neurode gen rative disease and 16 the best way to apply an effective treatment is its early diag nosis. The PET de17 vice will consist of several monolithic LYSO crystals coupl ed to SiPM detectors. 18 Monolithic crystals can reduce scanner costs with the advan tage to enable imple19 mentation of very small virtual pixels in their geometry. Th is is especially useful 20 for LM reconstruction algorithms, since they do not need a pr e-calculated system 21 matrix. We have developed an LM algorithm which has been init ially tested with 22 a large aperture (186 mm) breast PET system. Such an algorith m instead of us23 ing the common lines of response, incorporates a novel calcu lation of tubes of 24 Instituto de Instrumentaci ón para Imagen Molecular (I3M) Email address:agonzalez@i3m.upv. es (A.J. Gonźalez ) Preprint submitted to Nuclear Instru ents and Methods in Ph ysics: Section A August 8, 2012 response. The new approach improves the volumetric spatial reso ution about a 25 factor 2 at the border of the field of view when compared with tr aditionally used 26 MLEM algorithm. Moreover, it has also shown to decrease the i mage noise, thus 27 increasing the image quality. 28
The Predictability of REIT Returns and Market Segmentation

Recent research suggests that real estate returns are more predictable than the returns of other assets and that the real estate market is segmented from the general stock market. This study examines these two issues empirically using a multifactor asset pricing model that allows for time-varying risk premiums. The results indicate that, in a general two-factor asset pricing framework, the REIT market is integrated with the general stock market. Furthermore, no evidence can be found that REIT returns are more predictable than the returns of other stocks.
Use of Tuna Liver Meal as Partial Replacement of Fishmeal in Diets for Nile Tilapia Fry, Oreochromis niloticus

A 13-week feeding experiment was conducted to evaluate the use of tuna liver meal as a replacement for fishmeal in diets for Nile tilapia fry, Oreochromis niloticus. Six isonitrogenous (40%) and isoenergetic (18 kJ digestible energy/g) diets were formulated in which tuna liver meal replaced 0 (control), 10%, 20%, 30%, 40%, or 50% of the protein supplied by fishmeal. Triplicate groups of fish (2.29±0.07 g) were fed twice daily to apparent satiation. Results showed that final weight, weight gain, and specific growth rate of fish fed diets in which up to 30% of the protein was replaced by tuna liver meal did not significantly differ from fish fed the control diet. There were no significant differences in feed intake or protein efficiency ratio of fish fed diets containing up to 30% replacement. The apparent digestibility coefficients (ADC) of protein and energy significantly dropped with the increase in dietary tuna liver meal but there were no significant differences in the ADC of dry matter or lipid. There were no significant differences in protein or ash contents in the fish body, but dry matter and lipid contents significantly differed among treatments. Results indicate that up to 30% of fishmeal protein can be replaced by tuna liver meal in Nile tilapia fry diets without adverse effects on growth performance or feed efficiency.
Wireless Sensing for the Respiratory Activity of Human Beings: Measurements and Wide-band Numerical Analysis

An electromagnetic sensing system for the measurement of the respiratory activity is presented. The aims are to demonstrate the feasibility of the proposed approach and in particular to evaluate the effect on the measured signal of the distance between the subject and the sensing apparatus. Moreover, an electromagnetic model of the system, including the monitored subject, is proposed as a tool to solve the problem of selecting working parameters for system design. The sensing system is based on the measurement of the phase variation of the reflection coefficient caused by the respiratory activity. The phase signal compared with the thorax displacement measured by a reference instrument shows a high correlation () for different subject postures (sitting, standing, and lying) and a reduction of the signal amplitude with the distance dB/cm is reported. The numerical simulations performed on a wide-band highlight the frequencies where the method exhibits the highest sensitivity to thorax movements. The sensitivity can be further improved by reducing the antenna beamwidth. Despite the signal amplitude reduction, the proposed system makes it possible to correctly operate at distances up to 2.5 m.
Probiotic Dahi Containing Lactobacillus Acidophilus and Lactobacillus Plantarum Suppresses DMH Induced Preneoplastic lesions in early Colorectal Carcinogenesis in Wistar Rats

This study evaluated the chemopreventive effects of probiotic LaLp Dahi containing Lactobacillus acidophilus LaVK2 and Lactobacillus plantarumLp9 alone or as an adjunct with piroxicam (PXC)in male Wistar rats administered 1,2-dimethylehydrazine dihydrochloride (DMH). Colorectal carcinogenesis was induced by injecting DMH subcutaneously (40mg/kg body weight) twice a week for 2 weeks. Rats were divided into five groups, twenty four in each group and fed with the buffalo milk or probiotic supplements (20g) in addition to basal diet for 32 weeks.The rats were fed with buffalo milk or probiotic Dahi alone or in combination with PXC in addition to basal diet ad libitumand euthanized at 8th, 16th and 32nd weeks of the experiment and examined for development of aberrant crypt foci (ACF), mucin-depleted foci (MDF) and proliferating cell nuclear antigen (PCNA) labeling index. Administration of DMH in rats induced formation of preneoplastic lesions (ACF and MDF) and increased PCNA index in colorectal tissue. Probiotic Dahi alone or in combination with piroxicam showed a significant (P<0.05) protective effects by loweringthe initiation and progression of DMH induced formation of preneoplastic lesions and PCNA labeling index. These observations suggest that probiotic LaLp Dahi alone or in combination with PXC may be used as a potential nutraceutical intervention in prophylaxis and treatment of colorectal cancer.
Determinants of Milk Market Participation and Volume of Sales to Milk Collection Centres of the Smallholder Dairy Value Chain in Zimbabwe

At the attainment of Zimbabwe’s independence, government of Zimbabwe established the smallholder dairy development programme to encourage smallholder farmers to participate in formal milk markets. Although now more than three decades since the government established this programme, smallholder contribution to the national formal market remains low at 5%. This study was undertaken to determine factors affecting milk market participation and volume of sales to milk collection centres of the smallholder dairy value chain. Four smallholder dairy schemes were purposively selected on the basis of whether the scheme participated in the semi-formal or formal dairy value chain. A total of 185 farmers were then selected through simple random sampling and interviewed using a pretested structured questionnaire. Data were analysed using descriptive statistics and Heckman two-stage selection econometric models. Results show that resources (represented by dairy cows, household size), knowledge (educational level, access to information and extension), experience (household head age) and agro-ecological region significantly determined farmers’ participation in milk markets. The study also shows the determinants of milk sales volumes to be resources (number of dairy cows and landholding size); market access (distance to milk collection centre); ambition of the farmer (age); and natural climatic conditions (agro-ecological region). Government policy interventions therefore need to be targeted at increasing the number of dairy cows, taking into account landholding and market access, targeting educated, young farmers located in agro-ecological regions I and II, providing them with adequate, appropriate information and extension packages in order to enhance milk market participation and volume of sales.
Difference of toothbrushing motion between dental hygienists and mothers -Focusing on self-toothbrushing and caregivers’-toothbrushing

Aim: Because of the developing fine motor function of children, caregivers are encouraged to brush children’s teeth for them until they develop the skills to do so themselves. However, appropriate techniques for caregivers’-toothbrushing haven’t been clarified. This study evaluated the self-toothbrushing and caregivers’toothbrushing motions of dental hygienists and mothers. Design: Twenty female dental hygienists and twenty mothers participated in this study. A dental model of deciduous dentition attached to a dental education mannequin was used for caregivers’-toothbrushing with a manual toothbrush. Three-dimensional (3D) motions and forces were recorded using a toothbrush attached with a 3D accelerometer and a strain tension gage. The data were evaluated between the abovementioned two groups. Results: Dental hygienists demonstrated faster motion with lighter force than mothers during tooth brushing. Additionally, in caregivers’-toothbrushing, the displacement of toothbrush of dental hygienists was significantly shorter than that of mothers. Regarding the intra-individual correlations between self-toothbrushing and caregivers’-toothbrushing, significant correlations were found on the displacement of toothbrush for both groups. Conclusion: Dental hygienists might change their instructions on the brushing motion for caregivers’-toothbrushing whereas the caregivers’-toothbrushing by mothers is strongly reflected by the characteristics of self-toothbrushing. These findings might contribute to establishing tooth brushing instructions for mothers.

This paper proposed the direct torque control method for current source inverter fed PMSM to achieve high performance at low speed operation. During low speed operation estimation of stator flux and torque for direct torque control is very difficult due to the variation in stator resistance. This parameter variation from the set value affects the system at low speed of the PMSM. Many controlling techniques were introduced to compensate the stator resistance variation. A novel Fuzzy Logic Control method is used to compensate the stator resistance variation and the simulation results and hardware results are prove that the performance of the CSI fed PMSM has been improved.
Variability of planktonic and epiphytic vibrios in a coastal environment affected by Ostreopsis blooms

Vibrio s include several pathogenic bacteria that occur in aquatic environments. The presence of Vibrio has been assessed in many ecosystems by culture-based techniques. However, little is known on the contribution of Vibrio s in the sea, especially in areas subject to harmful algal blooms. A preliminary study in Sant Andreu de Llavaneres beach (NW Mediterranean) showed the presence of some Vibrio species during a recurrent bloom of the harmful benthic dinoflagellate Ostreopsis cf. ovata . In order to establish the importance of Vibrio s in a coastal area of the NW Mediterranean and to study the association with the dinoflagellate, we conducted a sampling monitoring for one year to quantify the concentration of Vibrio s both in the water (free-living and attached to particles) and in the epiphytic community of macroalgae. The aims were 1) to evaluate the relative abundance of Vibrio in the epiphytic and in the planktonic bacterial community, 2) to assess the percentage of free-living and attached Vibrio s in the planktonic community, and 3) to determine whether the presence of Vibrio s is associated with the blooms of the toxic dinoflagellate Ostreopsis or with other environmental parameters. For this purpose, a CARD-FISH molecular probe was applied for the specific detection of bacteria belonging to the genus Vibrio . Cells were quantified and the abundance of both particles and bacteria attached to particles were assessed. The maximum Vibrio concentration (1.3x104 cells ml –1 and 1.4x10 6 cells g –1 FW, for planktonic and epiphytic samples, respectively) was detected in September. Free-living Vibrio s contributed 0.38±0.24% to the total free-living planktonic community and 1.12±0.28% to the epiphytic bacterial community. However, their contribution was particularly high in the planktonic community attached to particles (17.37±20.49%). Although in the planktonic community Vibrio was found preferentially free-living (82.63±20.01%), particles are a niche for Vibrio s, since in particles Vibrio s may represent up to 72% of the total attached bacterial community. Abundance of planktonic Vibrio was correlated with Ostreopsis concentration and it is likely that they play a role in the wound infections suffered by beach users during the bloom.
Health capital and regional development. A panel data approach

The recent studies of economic growth have shown increasing interest in the potential economic profits that improved health condition of populations could bring. The World Health Organization’s reports Macroeconomics and Health: Investing in Health for Economic Development of 2001 and The Contribution of Health to the Economy in the European Union of 2005 significantly contributed to the promotion of health as a factor of economic growth. Both of them suggest that investing in health as a vehicle of economic growth is necessary not only in countries at a low level of economic development, but also in the developed ones. This recommendation arises from the fact that education and health are one of the basic determinants of the quality of human capital. On a micro scale, health is treated as a prerequisite for personal development, enabling the achievement of a satisfactory economic status. In terms of the entire economy, the beneficial influence of good health can manifest itself thorough growing productivity of labour, lower costs of absenteeism caused by sick leaves, and limited costs of medical interventions that altogether may improve social well-being and reduce poverty. Variations in economic results caused by health inequalities can be analysed for the entire economy, a region or with respect to individuals. The presented investigation aimed to verify a hypothesis, according to which the health condition of the regional population can be one of the factors determining regional development. The investigation used a panel sample comprising particular voivodeships as they were between 1999 and 2008. Application of dynamic panel data models allowed identifying a relationship between different health indicators and GDP variations.
Searching genes encoding Leishmania antigens for diagnosis and protection

Leishmaniases are a wide spectrum of parasitic diseases caused by the infection of different species of the genus Leishmania. Currently, these diseases are one of the most neglected diseases threatening 350 million people in different countries around the world. Thus, these diseases require better screening, diagnostics and treatment. An effective vaccine, that is not currently available, would be the best way to confront leishmaniases. In the past 20 years the molecular characterization of Leishmania genes encoding parasite antigens has been carried out. In this review we summarize the most common strategies employed for the isolation and characterization of genes encoding Leishmania antigens. To provide a collective view, we also discuss the results related with diagnosis and protection based on different recombinant DNA-derived Leishmania products.
U.K. Inflation Targeting and the Exchange Rate

The United Kingdom*s monetary policy strategy is one of floating exchange rates and inflation forecast targeting, with the targeted measure referring to consumer prices. We consider whether it is welfare-reducing to target inflation in the CPI rather than in a narrower index; and the role of the exchange rate in the transmission of monetary policy actions to CPI inflation. We argue that it is appropriate to model imports as intermediate goods rather than as goods consumed directly by households. This leads to a simpler transmission mechanism of monetary policy, while also offering a sustainable explanation fore the weakness of the exchange rate/inflation relationship and making consumer price inflation an appropriate monetary policy target.
The Architecture of an Information Revolution

Abstract The twenty-first century is already proving to be the real dawn of the information revolution. The internet is now officially coming of age and highly functional mobile devices are everywhere. The youth of today are permanently connected and the media world is shifting to a “born digital”, “on line first” mentality. Every part of our society is feeling the effects of this revolution and is reaping the benefits of “real time information everywhere” . or are they? Adrian Dale, in the second Willi Steiner Memorial Lecture, suggests that the reality is that many businesses are failing to keep pace with information growth and desperately need help – the question is from whom?
Prediction of electricity sales using neural based inverse distance weighting method

Prediction of electricity sales becomes important for State Electricity Company of Indonesia (PLN) in order to estimate the Statement of Profit and Loss in next year. To obtain good predictive results may require many variables and data availability. There are many available methods that do not require so many variables to get predicted results with a good approximation. The aim of this study was to predict electricity sales by using an interpolation method called IDW (Inverse Distance Weighting). Several data samples are mapped into Cartesian coordinates. The data samples used are power connected to the household (X-axis), to industry (Y-axis), and electricity sales (Z value). Firstly, the sampled data clustered by using SOM algorithm. The Z value in each cluster is predicted by using the IDW method. The prediction results of IDW method are then optimized using ANN-BP (Artificial Neural Network Back Propagation). The trained net structure is then used to predict the electricity sale in next year.
