title: Dataset on identification and correlation of secondary carbides on microstructure, wear mechanism, and tool performance for different cermet grades during high-speed dry finish turning of AISI 304 stainless steel

description: The aim of this study is to utilize reverse engineering approach for the identification of the elements and phases available on the commercial CERMET inserts with the help of characterization techniques such as Scanning Electron Microscope (SEM), Energy-dispersive X-ray spectroscopy (EDS), and X-Ray Deposition (XRD). Four commercial CERMET inserts were investigated in this research work and the effect of the composition and phases are related to it’s tool wear mechanism and performance. Each CERMET insert is used to perform a turning process on a CNC lathe for machining stainless steel (SS) under dry condition at a fix cutting length interval. Once it completes machining for a fix cutting length, the CERMET insert is taken out to investigate its wear mechanism with the help of SEM, EDS, XRD and using focus-variation microscope (Alicona). A correlation study is performed to relate progressive tool wear mechanism with elements and their relevant phases of various carbides. The approach of corelating wear property with the phase content will contribute for understanding of the wear mechanism under such extreme machining conditions. It will serve as a reference for the improvement of the performance of these CERMET inserts for such harsh machining condition by development of protective coatings for these CERMET inserts based on the identification of the composition and phases that improves tool life and reduces wear.

title: Psychometric Characteristics and Factorial Structures of the Defensive Pessimism Questionnaire - Spanish Version (DPQ-SV)

description: The aim of this study was to validate the Spanish version of the Defensive Pessimism Questionnaire. A sample of undergraduate students (N = 539) was measured on defensive pessimism using the Defensive Pessimism Questionnaire (DPQ), optimism and pessimism using the Life Orientation Test (LOT), positive and negative affect using the Positive and Negative Affect Schedule, and anxiety using the trait subscale of the State and Trait Anxiety Inventory. A Spanish version of the DPQ (DPQ-SV) is presented. Exploratory and Robust Confirmatory Factor Analysis had a bi-dimensional structure (Reflectivity and Negative Expectation). Omega coefficient showed a high internal consistency and the temporal stability was high in each dimension. Both DPQ-SV subscales (Negative Expectation and Reflectivity) showed adequate convergence with LOT-optimism and LOT-pessimism. Reflectivity showed adequate criterion validity with trait-anxiety and negative affect, but inadequate criterion validity with positive affect. Negative Expectation showed excellent criterion validity with trait-anxiety and negative affect and good criterion validity with positive affect. Finally, mediation analysis showed that Negative Expectation had a significant indirect mediating effect between trait-anxiety and negative affect. Reflectivity had a significant indirect mediating effect between trait-anxiety and negative and positive affect. Analysis of the psychometric properties of the DPQ-SV subscale scores showed that it is a two factor adequate measurement tool for its use in this type of samples.

title: The Effect of Working Memory Load on Evaluative Priming

description: TheThe present study examined the role of working memory in an evaluative priming paradigm, in which primes that are affectively congruent or incongruent are presented prior to a target stimulus. Studies typically observe a congruity effect, whereby responses to a congruent target-prime pairing are facilitated. However, research has also demonstrated an incongruity effects: whereby incongruent target-prime pairings are facilitated. It is theorized that the incongruity effect occurs due to a corrective mechanism. To examine the role of working memory in the evaluative priming, a within-subjects design was employed, in which working memory load, congruency, and target valence were manipulated. Firstly, the findings indicated an incongruity effect. Secondly, it seems that working memory is the cognitive resource implicated in expectancy-based strategies, as a working memory load reduced accuracy and increased response latencies to targets. Thirdly, the results revealed that the incongruity effect is attenuated by working memory load, suggesting that the incongruity effect is dependent on the availability of cognitive resources. The study also observed a happy face target recognition advantage. One implication of the present study is that that evaluative priming can occur via expectancy-based strategies when SOAs are long.

title: NITRATE LEVELS IN BELIZE’S RURAL DRINKING WATER

description: This study examined nitrate levels in Belize’s rural water supply with the aim to providing a baseline data for monitoring the concentration of nitrates as a means to preventing public health hazards. 2 water samples were conveniently collected from reservoirs, wells, vats and standpipes from 40 villages using plastic bottles. Plastic bottles were used to collect water samples from 43 water samples from 40 villages in all the districts of the country of Belize (Figure 5). 1000ml bottles were purchased from Bowen & Bowen Limited®, thoroughly rinsed with purified water, dried and used for water samples collection. Before sample collection, the bottles were also thoroughly rinsed with the respective water samples at the site of collection. 15 water samples were collected from reservoirs, 10 from wells, 3 from standpipes (boreholes) and 15 from vats (Figure 3). Water samples were also collected from each district in the country. 9 water samples were collected each from Belize and Toledo districts; 8 from Cayo; 5 each from Corozal and Stann Creek and 7 from Orange Walk. 2 water samples were collected from either a reservoir, a vat, a standpipe, a well or both depending on what is available in the village. Collected water samples were immediately transported to the laboratory of Belize Coastal Zone Institute and analyzed for nitrates. Water samples that were not immediately analyzed were filtered and refrigerated below 4o C till analyzed. Testing and Analysis was done according to USA EP for Nitrate-Nitrite Analysis Procedures as described. For quality assurance, each sample was analyzed twice and results statistically computed and presented. The one-way analysis of variance (ANOVA) test was performed to compare the sets of data obtained from different sites. The difference among mean analyzed by one way ANOVA was further analyzed using student t-test. A value of P≤ 0.05 was considered statistically significant. Data was presented as the arithmetic mean ± S.D. Estimated nitrates levels in water samples were compared with EPA’s acceptable safe drinking water levels and presented. Except for 4 water samples from 4 different sites, all other water samples analyzed were found to contain nitrates levels below 10mg/L. Nitrate levels above 10mg/L were seen in few samples in the northern part of the country probably due to agricultural activities in these areas. Belize’s rural drinking water contains low levels of nitrates except for a few villages that the levels exceeded the acceptable 10mg/L. Higher levels of nitrates detected in those villages need regular evaluation and monitoring to avoid public health issues as well as prevent harm to livestock.

title: Nairobi Securities Exchange Prices 2008-2012 for 6 selected stocks

description: Stock market prediction remains active research in a quest to inform investors on how to trade (buy/sell) at the most opportune time. The prevalent methods used by stock market players in trying to predict the likely future trade prices are either technical, fundamental or time series analysis. This research wanted to try out machine learning methods, in contrast to the existing prevalent methods. Artificial neural networks (ANNs) tend to be the preferred machine learning method for this type of application. However, ANNs require some historical data to learn from, in order to do predictions. The research used an ANN model to test the hypothesis that the next day price (prediction) can be determined from the stock prices of the immediate last five days. The final ANN model used for the tests was a feedforward multi-layer perceptron (MLP) with error backpropagation, using sigmoid activation function, with network configuration 5:21:21:1. The data period used was a 5-year dataset (2008 to 2012), with 80% of the data (4-year data) used for training and the balance 20% used for testing (last 1-year data). The original raw data for Nairobi Securities Exchange (NSE) was scrapped from a publicly available and accessible website of a stock market analysis company in Kenya (Synergy, 2020). This data was first exported to a spreadsheet, then cleaned off headers and other redundant information, leaving only the data with stock name, date of trade and the related data such as volumes, low prices, high prices and adjusted prices. The data was further sorted by the stock names and then the trading dates. The data dimension was finally reduced to only what was needed for the research, which was the stock name, the date of trade and the adjusted price (average trade price). This final dataset was in CSV format, as hereby presented. The research tested three NSE stocks with the mean absolute percentage error (MAPE) ranging between 0.77% to 1.91%, over the 3-month testing period, while the root mean squared error (RMSE) ranged between 1.83 and 3.07. This raw data can be used to train and test any machine learning model that requires training and testing data. The data can also be used to validate and reproduce the results already presented in this research. There could be slight variance between what is obtained when reproducing the results, due to the differences in the final exact weights that the trained ANN model eventually achieves. However, these differences should not be significant.

title: Political uncertainty, realized volatility and jumps in the Chinese stock market

description: Our initial sample consists of all the Chinese A-share listed firm samples spans from January 1, 2014 to December 31. The 5-min frequency price data and the single trading data containing the price, volume and the buying/selling initiation information are collected from the CSMAR high-frequency database; the former data are used to calculate the RV. Following Wang et al. (2016), we use the local official replacement to measure the LPU, that is, for the firm i in day t (in month m), LPUi,t takes the value of 1 if observing a mayor or the party head turnover during the (m-1, m+1) months in the firms’ registered prefecture city, and 0 otherwise. The detailed information of local government official replacements is collected from China Economic Net (http://www.ce.cn/) and other authoritative government website manually. The political sensitively data include the “innate” state ownership (SOE) and the “postnatal” Chairman/CEO political connection (PC), which are collected from the CSMAR database and compiled as Fan et al. (2007). We delete the sample-firms going public and the firms with trading days less than two years, and the samples with missing variables. Finally we get 2048676 daily samples comprising 2318 firms, with the maximum length of 1219 trading days.

title: EFFICACY OF ARTEMETHER LUMEFANTRINE WHEN CO-ADMINISTERED WITH CIPROFLOXACIN IN MALARIA-TYPHOID CO-INFECTED PATIENTS IN UNWANA SOUTH EAST NIGERIA.

description: An assessment of the efficacy of artemether lumefantrine when orally co-administered with ciprofloxacin in the treatment regimen of malaria and typhoid co-infection was carried out in this study. One hundred and nineteen (119) febrile volunteers comprising 55 males and 64 females were distributed into three oral treatment regimen groups: malaria infected individuals treated with AL (Group 1), malaria-typhoid co-infected individuals treated with AL and ciprofloxacin concomitantly (Group 2), and the dose staggered at 2 hours interval (Group 3). Parasitaemia on days 0, 3 and 7 were assessed by thick blood film microscopy. Changes in liver, kidney function and haematological indices on day 7 and day 7 lumefantrine concentration were assessed in the three groups using standard methods. Result: Co-administration treatment regimen (Group 2) was associated with significantly higher (p &lt; 0.05) Late Parasitological Failure (LPF) and mean day 7 blood lumefantrine concentration when compared to AL (Group 1) and staggered dosing (Group 3) treatment regimens. Mean values of liver, kidney function parameters, PCV and haemoglobin were not significantly different (p &gt; 0.05) in Group 3 when compared to Group 1. Conclusion: Oral co-administration of AL with ciprofloxacin is associated with drug-drug interaction but the therapeutic implications for the efficacy of AL remains unclear.

title: Evaluation of performance characteristics of a novel hydrogen-fuelled free-piston engine generator [dataset]

description: MATLAB software is required to open the files.
description: In this work, we present the experimental results obtained from hydrogen fuelled spark-ignited dual piston free-piston engine generator (FPEG) prototype operated in two-stroke and four-stroke mode. The FPEG testing was successfully conducted at 3.7 compression ratio, engine speed between 5Hz and 11Hz and with different equivalence ratios. The FPEG technical details, experimental set-up and operational control are explained in detail. Performance indicators show that both equivalence ratio and engine speed affect the engine operation characteristics. For every set of specified FPEG parameters, appropriate range of equivalence ratio is recommended to prevent unwanted disturbance to electric generator operation. Both two-stroke and four-stroke cycle mode were tested, and the results showed different combustion characteristics with the two thermodynamic cycles. Four-stroke cycle mode could operate with indicated thermal efficiency gain up to 13.2% compared with the two-stroke cycle.
