Binder effect on electrochemical performance of zinc electrodes for nickel-zinc batteries

Abstract: Polyethylene glycol (PEG) and polyvinyl alcohol (PVA) were used as a zinc electrode binder at different concentrations to enhance the electrochemical behavior of zinc electrodes for nickel-zinc (NiZn) batteries. ZnO powders synthesized by mechanochemical and hydrothermal precipitation methods were mixed with lead oxide, calcium hydroxide and binder to prepare zinc electrodes in pouch cell NiZn batteries. Scanning Electron Microscopy (SEM) and X-Ray Diffraction (XRD) analysis reveal that initial morphology of zinc electrode changes drastically regardless of the binder type and its loading after charge/discharge process, and even the charge/discharge process is not complete. The results show that the presence of PEG causes better discharge capacity compared to that of PVA as a binder. Zinc electrode prepared using commercial ZnO powder and 3 wt. % PEG gives the optimum discharge capability, with a specific capacity of approximately 311 mAhg, while zinc electrodes prepared using ZnO powder synthesized from ZnCl2 and Zn(NO3)2.6H2O and 6 wt. % PEG exhibit high specific energy of 255 and 275 mAhg, respectively. The results suggest a relationship between binder loading and battery capacity, but in-situ analysis of microstructural evolution of zinc electrode during charge/discharge process is needed to confirm this relationship.
Escherichia coli O 157 : H 7 forms attaching and effacing lesions at the terminal rectum of cattle and colonization requires the LEE 4 operon

Received 22 March 2005 Revised 20 May 2005 Accepted 24 May 2005 Enterohaemorrhagic Escherichia coli O157 :H7 is a human pathogen that causes no apparent disease in cattle, its primary reservoir host. Recent research has demonstrated that E. coli O157 :H7 predominately colonizes the distal few centimetres of the bovine rectum, and in this study, the LEE4 operon encoding a type III secretion system translocon and associated proteins was shown to be essential for colonization. A deletion mutant of LEE4 failed to colonize cattle, in contrast to a co-inoculated strain containing a chromosomal complement of the operon, therefore fulfilling ‘molecular’ Koch’s postulates for this virulence determinant. In addition, attaching and effacing (A/E) lesions were detectable in E. coliO157 :H7 microcolonies from the terminal rectum of both naturally and experimentally colonized cattle when examined by transmission electron microscopy. This study proves that type III secretion is required for colonization of cattle by E. coli O157 :H7, and that A/E lesion formation occurs at the bovine terminal rectum within E. coli O157 :H7 microcolonies. The research confirms the value of using type III secreted proteins as vaccine candidates in cattle.
Ages and fundamental properties of Kepler exoplanet host stars from asteroseismology

We present a study of 33 {\it Kepler} planet-candidate host stars for which asteroseismic observations have sufficiently high signal-to-noise ratio to allow extraction of individual pulsation frequencies. We implement a new Bayesian scheme that is flexible in its input to process individual oscillation frequencies, combinations of them, and average asteroseismic parameters, and derive robust fundamental properties for these targets. Applying this scheme to grids of evolutionary models yields stellar properties with median statistical uncertainties of 1.2\% (radius), 1.7\% (density), 3.3\% (mass), 4.4\% (distance), and 14\% (age), making this the exoplanet host-star sample with the most precise and uniformly determined fundamental parameters to date. We assess the systematics from changes in the solar abundances and mixing-length parameter, showing that they are smaller than the statistical errors. We also determine the stellar properties with three other fitting algorithms and explore the systematics arising from using different evolution and pulsation codes, resulting in 1\% in density and radius, and 2\% and 7\% in mass and age, respectively. We confirm previous findings of the initial helium abundance being a source of systematics comparable to our statistical uncertainties, and discuss future prospects for constraining this parameter by combining asteroseismology and data from space missions. Finally we compare our derived properties with those obtained using the global average asteroseismic observables along with effective temperature and metallicity, finding an excellent level of agreement. Owing to selection effects, our results show that the majority of the high signal-to-noise ratio asteroseismic {\it Kepler} host stars are older than the Sun.

Edinburgh Research Explorer Generalizing the Pigeonhole Principle for Similarity Query Processing in Hamming Space

—A distance search in Hamming space ﬁnds binary vectors whose Hamming distances are no more than a threshold from a query vector. It is a fundamental problem in many applications, such as image retrieval, near-duplicate Web page detection, and scientiﬁc databases. State-of-the-art approaches to Hamming distance search are mainly based on the pigeonhole principle to generate a set of candidates and then verify them. We observe that the constraint by the pigeonhole principle is not always tight and may bring about unnecessary candidates. We also observe that the distribution in real data is often skew, but most existing solutions adopt a simple equi-width partitioning and allocate the same threshold to all the parts, hence failing to exploit the data skewness to optimize query processing. In this paper, we propose a new form of the pigeonhole principle which allows variable partitioning and threshold allocation. Based on the new principle, we develop a tight constraint of candidates and devise cost-aware methods for partitioning and threshold allocation to optimize query processing. In addition, we extend our methods to answer Hamming distance join queries. We also discuss the application of the pigeonhole principle in set similarity search, a problem that can be converted to Hamming distance search equivalently. Our evaluation on datasets with various data distributions shows the robustness of our solution and its superior query processing performance to the state-of-the-art methods.
Determinants of Rural Households’ Decision Making to Forgo Income for Bequeathed Woodlot in Uasin Gishu County, Kenya

Forests are an important economic good in providing dependable products by rural households such as fuel wood, food supply, natural insurance and as habitat for pollinators; however, unchecked household characteristics that abet exploitation and/or unsustainable consumption of forest products expose livelihoods of rural households who are forest resource dependants to be at perilous state. Therefore, this study sought to examine demographic and socio economics determinants that influences rural households decision making to forgo income for conservation through bequeathed tree planting in Uasin Gishu County, Kenya. Systematic random sampling technique was applied in selecting samples whereby a total of 234 structured questionnaires were administered to rural household’s heads for interview. Results from regression analysis showed that rural households with existing woodlot in their farms and family size were negative and significant at (-2.501, p< 0.05) and (-1.857, p< 0.1) respectively, which suggests to influence the desire for rural households not to forgo income for bequeathed woodlot in their farm, while constructs of dependency level on forest products by rural homes 1.720, p< 0.1, the costs of establishing woodlot at 0.992, p< 0.001 and agro-ecological condition of land at 1.784, p< 0.1, which were positive and statistically significant were likely to influence rural homes to engage in tree planting as insurance venture for the future generation of which $234.19 was the likely annual premium. In conclusion, the critical determinants that influence rural homes’ decision making to forego income for bequeathed woodlot informs policy makers, scholars and resource managers on rural households’ characteristics needed while formulating strategies and policies needed for up-scaling forests land cover to mitigate climate change effect. However, the positive and statistically significant of stochastic variable from OLS model, which explains variables that were omitted and/or were beyond the scope of this study and remained unobserved, showed influence on rural household decision making to forgo income for conservation stewardship; hence, creating knowledge gap for further investigation.
Incentivizing the Creative Process: From Initial Quantity to Eventual Creativity

In two experiments, we examine whether performance-contingent incentives facilitate the creative process by enhancing the initial preparation that precedes creative incubation. The defining characteristic of both experiments is a second-stage task that is separated in time from the first-stage implementation of different incentive schemes. In Experiment 1, the second stage takes place ten days after we implement conditions with quantity incentives, high-creativity incentives, incentives with a minimum-creativity threshold, and a fixed-pay control condition. In Experiment 2, we test the effects of incentives with an incubation period of 20 minutes, during which an experimenter escorts participants on a walk between compensated work periods. In both experiments, we find that participants with quantity incentives outperform the high-creativity production of their fixed-pay counterparts only in the second-stage task. Mediation analyses suggest that quantity-incentivized participants' propensity to try more divergent ideas in the first stage sparks their creativity advantage in the second stage.

A CRITICAL APPROACH TO THE PARTICLE SWARM OPTIMIZATION METHOD FOR FINDING MAXIMUM POINTS

Particle Swarm is an optimization method that is used for solving industrial problems and is highly preferred due to its ease of use and it’s ability to find accurate results rapidly in recent years. In this study, it was used to optimize the resistance value of train sets. There are many types of resistance in train sets and the train can't start moving until the traction motors overcome the resistances. Run resistance, ramp resistance, and curve resistance are the resistances that the train must overcome at a constant speed. However, it is known that the acceleration of high-speed trains is very high and the resistance that the train sets must overcome for the change in speeds is acceleration resistance. This study aimed to calculate the acceleration, time, curve, ramp and distance, under certain constraints, for the total resistance value of YHT 65000 train by using the Particle Swarm Method as to obtain the minimum and maximum. Although, the results showed that the Particle Swarm Method returned very successful results for the minimum resistance, the same cannot be said for the maximum resistance.
Vortex-induced chaotic mixing in wavy channels

Mixing is studied in open-flow channels with conformally mapped wavy-wall profiles, using a point-vortex model in two-dimensional irrotational, incompressible mean flow. Unsteady dynamics of the separation bubble induced by oscillatory motion of point vortices located in the trough region produces chaotic mixing in the Lagrangian sense. Significant mass exchange between passive tracer particles inside and outside of the separation bubble forms an efficient mixing region which evolves in size as the vortex moves in the unsteady potential flow. The dynamics closely resembles that obtained by previous authors from numerical solutions of the unsteady Navier–Stokes equations for oscillatory unidirectional flow in a wavy channel. Of the wavy channels considered, the skew-symmetric form is most efficient at promoting passive mixing. Diffusion via gridless random walks increases lateral particle dispersion significantly at the expense of longitudinal particle dispersion due to the opposing effect of mass exchange at the front and rear of the particle ensemble. Active mixing in the wavy channel reveals that the fractal nature of the unstable manifold plays a crucial role in singular enhancement of productivity. Hyperbolic dynamics dominate over non-hyperbolicity which is restricted to the vortex core region. The model is simple yet qualitatively accurate, making it a potential candidate for the study of a wide range of vortex-induced transport and mixing problems.
Effect of Phyllosphere Application of Methylobacterium on Growth and Yield of Barnyard Millet (Echinochloa frumentacea Var. COKV 2)

Bio-fertilizer can be an important component of integrated nutrients management. Microorganisms that are commonly used as bio-fertilizer components include; nitrogen fixers (N-fixer), potassium and phosphorus solubilizers, growth promoting rhizobacteria (PGPRs), endo and ecto mycorrhizal fungi, cyanobacteria and other useful microscopic organisms. The use of bio-fertilizers leads to improved nutrients and water uptake, plant growth and plant tolerance to abiotic and biotic factors. These potential biological fertilizers would play a key role in productivity and sustainability of soil and also International Journal of Current Microbiology and Applied Sciences ISSN: 2319-7706 Volume 9 Number 4 (2020) Journal homepage: http://www.ijcmas. com
Evaluating students' self-assessment in large classes

This study is part of an ongoing larger project concerning student self-assessment skills in university courses. We have developed a method enabling large cohorts of students to assess their own learning outcomes and to give their own course grades with the help of an automatic verification system. This paper explores the question of accuracy, namely, whether the self-assessed grades correspond to the students’ actual skills, and how well the automatic system can pick up issues in the self-assessment. Based on an expert’s evaluation of the skills of two students, we conclude that although for large part the model works as intended, there are some cases where neither the self-assessment nor the computer verification seem to be accurate.
Trade Competition, Technology and Labour Reallocation

This paper provides new evidence on the reallocation of workers across firms and industries with different technologies in response to increased import competition from developing countries. Using employer-employee matched data for the Swedish manufacturing sector, we find increased assortative matching of workers in ICT (information and communication technologies) intensive industries, that is, high(low)-wage workers sort into high(low)-wage firms. Industries with low ICT intensity do not exhibit these sorting patterns. A labour market matching model explains the increased assortative matching in ICT intensive industries in response to stronger import competition through an increase in the relative demand for qualified workers.
ROLE OF ADHESION MECHANISMS IN THE PATHOGENESIS OF CHRONIC SYNOVmS

The hallmark of many rheumatic conditions, including rheumatoid arthritis (RA) and other seronegative inflammatory arthropathies (OIA), is a persistent inflammatory process that mainly affects synovial joints. Although the aetiology of the synovitis remains elusive, the pathogenesis is thought to be immune mediated. There are several reasons to believe that synovial T lymphocytes (S-TL) play a central role both as regulatory and effector cells in the initiation and perpetuation of the inflammatory process. In early studies, we demonstrated that the majority of S-TL are of the CD45R0 'memory' phenotype, while CD45RA 'naive' T cells are virtually absent [1,2]. Various mechanisms can be responsible for such preferential accumulation. In this dissertation, I will present a number of studies, carried out over several years, investigating the relative role of adhesion and migration in the pathogenesis of the CD45R0 accumulation in inflamed tissues. Since the first step in lymphocyte extravasation is adhesion to endothelium, the ability of purified CD45R0 vs CD45RA T cells to adhere to human umbilical vein endothelial cells (HUVEC) in vitro was analysed [3]. Second, to examine the migration process itself, an in vivo model of cell migration into suction-induced skin blisters raised over delayed-type hypersensitivity reactions was developed [4]. Third, the role of tissue-specific homing mechanisms in the regulation of T-cell migration into different inflammatory sites was investigated [5]. Finally, the adhesion of T cells to extracellular matrix (ECM) components, as a mechanism for preferential cell retention in inflamed tissues, was examined [6]. These studies demonstrate that the critical mechanisms leading to CD45R0 lymphocyte accumulation in chronic inflammatory foci include (a) an increased adhesion to endothelium [3], (b) an increased migratory capacity [4] and (c) an increased adhesion to ECM components [6]. I also present evidence to suggest that besides these general mechanisms, organ-specific homing may be of relevance in determining the selective accumulation of distinct CD45R0 T cells in different inflamed tissues [5].
Human Capital Development and Service Delivery of Public Health Facilities

Healthcare provision stipulated by Sustainable Development Goals (SDGs) is a relatively new concept in many developing countries Sub-Saharan Africa part of Asia. Therefore, this study examined the influence of human capital development on the service delivery of devolved County Health Facilities. The path coefficients were positive and significant at 0.05 level of significance. The path coefficient beta value was β = 0.50. These findings indicate that for every 1-unit increase in human capital development, service delivery is predicted to increase by 0.5 in public county health facilities in Kenya. The study concluded that measures contributed to the positive relationship between human capital development and service delivery in these facilities. As the hospitals lacked funding of further training for their staff and also failed to pay competitive salaries and allowances, the study recommends that for improved service delivery within these facilities, promotions should be on performance, as well remuneration. Most employees will work hard when they know that they get rewards for it. The hospitals should also promote staff and offer scholarships for training to the high performing staff.
Demonstrating a Qualitative Control of a Hybrid Energy System in Reducing Energy Costs of a Residential Building

Today, many buildings are equipped with several renewable energy sources. The problem is how to take full advantage of their energy production. This includes decreasing the share and costs of external energy usually electrical energy delivered from the grid. The following pages present a qualitative control designed to solve the problem. The approach is demonstrated using a simulated residential building equipped with a hybrid energy system: an energy storage combined with an electrical heater, a geothermal heat pump and a solar thermal collector. Consequently, the share of renewable energy was increased, and conversely, costs and share of the external energy from grid decreased. Still, the indoor conditions could be kept at a comfortable level. The method serves as one approach in developing a generic control strategy for multi-energy buildings.
Banking, labor force, and regional economic growth: Evidence from Indonesia

This paper examines whether regional economic growth across Indonesian provinces can be affected by the role of banking and labor force. In general, our empirical findings show that banking development is indeed positively linked to regional economic growth, although this relationship is more pronounced for poor provinces. Moreover, this paper finds that the link between banking development and regional economic growth is conditional on the degree of labor force. Specifically, the positive impact of banking on regional economic growth only occurs when labor force is sufficiently low regardless of whether we observe poor provinces or rich provinces. Eventually, this paper highlights that increasing access to bank credit is essential to boost regional economic growth, especially for poor provinces or provinces with lower labor force.
