Heart Failure Predictive Analysis Using Decision Tree Classification
Authors: Subbarao Manne Venkata
Published: July 2024

With an average age of 28 compared to Western countries, India's young population accounts for half of heart attacks in South Asia, which happen to people under 52. Autopsy reports, which identify the actual cause of death, frequently concentrate on sudden deaths in young adults that have no apparent reason or warning signs. Fat accumulation in the blood vessels of the heart is the cause of abrupt, unexpected natural deaths. The heart stops beating and loses blood as a result of these arteries narrowing or blocking. The body may exhibit subtle symptoms prior to abrupt death, such as shortness of breath, palpitations, tightness in the chest, and chest discomfort. A decision tree classification is a death dataset model that generates labelled classes at leaf nodes and makes judgments at edges to predict class labels for subsequent records. The purpose of the proposed paper study is to predict abrupt natural deaths, which are frequently brought on by smoking, by using regression analysis, a statistical technique that establishes the relationship between independent and dependent variables. The experiment's outcome, which looks at how Artificial Neural Networks (ANN) may be used to forecast heart failure, shows five records out of 50,000 patients from different hospitals. Perceptron’s, both single- and multi-layer, were used to gather patient information.

Selective and Market Timing Skills: An Empirical Evaluation of Equity Mutual Funds in an Emerging Market
Authors: D. A. Ajadi
Published: July 2024

This study evaluates the selective and market timing skills of mutual funds managers using monthly net asset values of all 30 actively managed equity-based funds that operated from January 2012 to December 2021 obtained from the Securities and Exchange Commission. Selectivity is the ability to search for and choose undervalued securities to exploit the sub-optimal market weights of securities, while market timing is the ability to forecast the direction of the market and adjust portfolio betas to generate alpha. Two regression models, namely the Treynor-Mazuy (1966) and Henriksson-Merton (1981) were deployed for the study. The findings indicate that mutual funds did not exhibit significant selective skills or market timing abilities. This outcome is consistent with the Efficient Market Hypothesis (EMH). Consequently, it becomes challenging for investors or fund managers to consistently outperform the market through stock selection or market timing. Based on the study's results, the recommendation for investors is to consider low-cost passive investment strategies, such as index funds or exchange-traded funds (ETFs), over actively managed funds.

Published: July 2024

Water scarcity can be overcome through the reuse of treated wastewater for irrigation especially in arid and semiarid regions. However, there are several potential environmental and health risks associated with this practices. Improved plant growth and nutrients for microorganisms are also gotten from wastewater which has high nutritive value. This study investigated the effect of rice mill waste water on cocoon production and total population of earthworm Eisenia fetida under laboratory conditions. A total of five hundred (500) clitella earthworms were used for this study. The physico-chemical parameters of the rice mill wastewater were analyzed using standard methods of APHA-AWWA-WEF (2000). The study on the cocoon production and total population of E. fetida were conducted from 0 to 100% wastewater (0, 25, 50, 75 and 100%) by serial dilution for a period of 60 days to assess the suitability of rice mill wastewater for irrigational purpose. The significant difference between treatments was tested by one-way ANOVA. The wastewater had an alkaline pH (8.5), low sulphate (0.95 mg/l), DO (3.10mg/l) and COD (2.0mg/l); moderate concentration of TDS (421mg/l), calcium (47.7 mg/l), phosphate(102.27 mg/l) and high concentration of conductivity (20.50 dsm-1), total solid (2550mg/l), total dissolved solids (2028 mg/l), total hardness (100 mg/l) and sodium (25.0 mg/l), earth population(53.2) At 50% of the wastewater usage there was a significant increase in cocoon production (24.24). On the basis of this research, it shows that rice mill wastewater should be either diluted to at least 50% or treated to make it suitable for irrigational purpose.

Further, it explores MPC's model predictive torque control, demonstrating its proficiency in handling various requirements through a well-designed cost function. Overall, this research emphasizes MPC's adaptability and efficiency in optimizing DFIG-WT performance under varying operational conditions.
Soil Acidity Causes in Ethiopia, Consequences and Mitigation Strategies-A Review
Authors:   Oromia Agricultural Research Institute, Nekemte Soil Research Center, Oromia, Ethiopia, Tadesse Amanuel
Published: July 2024

Soil acidity is a serious land degradation problem and worldwide danger, impacting approximately 50% of the world's arable soils and limiting agricultural yield. Soil acidification is a complicated series of events that lead to the production of acidic soil. In its widest sense, it can be defined as the total of natural and human processes that reduce the pH of soil solutions. Soil acidity affects around 43% of agricultural land in Ethiopia's humid and sub humid highlands. Acid soils in western Ethiopia are mostly caused by topsoil erosion caused by heavy rains and high temperatures. This results in the loss of organic matter and the leaching of exchangeable basic cations (Ca2+, Mg2+, Na+, and K+). Because ammonium-based fertilizers are easily converted to nitrate and hydrogen ions in the soil, they play a significant role in acidification. One of the reasons of soil acidity is inefficient nitrogen usage, which is followed by alkalinity exports in crops. Soil acidity in Ethiopian highlands is mostly caused by the clearance of crop residues, continuous crop harvest without sufficient fertilization, cation removal, and usage of acid-forming inorganic fertilizers. Acid soil reduces nutrient availability and produces Al and Mn toxicity. In addition to these effects, soil acidity may rapidly degrade soil physicochemical qualities such as organic carbon (OC), cation exchange capacity (CEC), soil structure, porosity, and texture. Liming, the use of organic materials as ISFM, and the adoption of crop types that are resistant to Al toxicity are all alternatives for correcting acid soils. Liming can minimize toxicity by lowering concentrations, improving the availability of plant nutrients like P, Ca, Mg, and K in the soil, and reducing heavy metal solubility and leaching. Application of organic matter has a liming impact because of its abundance in alkaline cations (such Ca, Mg, and K) that were released from OM during mineralization. The pH of the soil is raised by soil organic matter, which helps with soil acidity supplements.

A cheap and ecologically friendly pre-sowing method that increases germination rates and seedling vigor, which in turn enhances growth and productivity, is considered seed priming. A field experiment was conducted in 2022 in farmer’s field to evaluate the effective priming method suitable for the balanced germination, growth, and yield of maize. An experiment consists of a single-factor randomized complete block design with 3 replications and 8 treatments. The analysis of the data was conducted with R Studio software at the p <0.05 level of significance, and a mean comparison was done using DMRT (Duncan's Multiple Range Test). According to this study, seed priming increased the germination, growth, and yield of crop growth parameters such as germination percentage, germination index, days to 100% germination, stem diameter at 35 days, days to 100% tasseling, days to 100% silking, plant population/ha, number of cobs per plant, ear length, ear girth, kernels per cob, 1000 kernel weight, fresh grain yield, adjusted grain yield, fresh Stover yield, and fresh biomass yield. The highest germination percentage (98.61%) and index (11.89 days), the earliest days to 100% germination (12.00 days), early tassel emergence (63.00 days), early silking emergence (66.00 days), the highest number of kernels per cob (529.37), 1000 kernel weight (337.10 g), harvest index (0.62), ear length (22.38 mm), and ear girth (49.72mm) were recorded on the treatment primed with cow urine for 18 hours. However, the highest fresh Stover yield (2954.07 kg/ha) and fresh biomass yield (6336.29 kg/ha) are recorded on stoves primed with DAP for 18 hours. Cow-urine priming for 18 hours improved the germination and economic yield of maize. Efficient cow-urine priming is a cost-effective, eco-friendly, and finest alternative approach to increasing the maize yield.

Cauliflower is one of the most important and preferred vegetables and effective nutrient management is essential to improve production as well as soil properties. Thus, the study was conducted to examine the impact of integrated nutrient management on cauliflower and soil at Ghorahi, Dang district of Nepal. The single-factor experiment was organized employing a Randomized Complete Block Design with three replications. In this study, nitrogen (N) was applied through different sources viz 100% N via urea, 50% N via urea + 50% N via farmyard manure, 50% N via urea + 50% N via pig manure, 50% N via urea + 50% N via vermicompost, 50% N via urea + 25% N via farmyard manure + 25% N via pig manure, 50% N via urea + 25% N via pig manure + 25% N via vermicompost, 50% N via urea + 25% N via farm yard manure + 25% N via vermicompost and 50% N via urea + 50% N via (farmyard manure + pig manure + vermicmpost in 1:1:1). Among different treatments, 50% N via urea + 50% N via vermicompost recorded the highest curd diameter (17.72 cm), curd height (11.57 cm), curd weight (0.76 kg), curd yield per hectare (31.67 t ha-1), soil organic matter (3.31%), total nitrogen (0.157%), available phosphorus (76.78 kg ha-1) as well as available potassium (860.20 kg ha-1). Therefore, it is suggested to apply 50% N via urea and 50% N via vermicompost for better cauliflower production and soil properties.

Phosphorus (P) scarcity poses a significant challenge to sustainable agriculture, impacting plant growth and crop productivity. While arbuscular mycorrhizal (AM) fungi have been extensively studied for their role in enhancing phosphorus acquisition, this review explores the potential of diverse microflora as alternative solutions. The diverse microflora groups, including rhizobacteria, actinomycetes, and cyanobacteria, contribute to phosphorus availability through various mechanisms. These microfloras produce organic acids, enzymes, and chelators that enhance phosphorus solubility and mineralization, facilitating nutrient cycling. Moreover, they promote root growth, nutrient uptake efficiency, and plant growth through the production of growth-promoting substances. Unravelling the molecular interactions between microflora and plants has provided insights into signalling pathways and genetic mechanisms governing the symbiotic association. Harnessing the power of diverse microflora offers potential benefits, including reduced reliance on chemical fertilizers, improved nutrient use efficiency, and environmental sustainability. Future research directions involve exploring unexplored microflora groups, manipulating microbial communities, and integrating microflora-based strategies with precision agriculture technologies. This review highlights the significance of diverse microflora as alternative solutions to address phosphorus scarcity and advance sustainable agricultural practices.
Nonlinear acoustics of an aperture under grazing flow
Authors: Stoychev Alexander , Noiray Nicolas
Published: July 2024

This work presents a mathematical model of a dynamically forced, acoustically compact aperture subject to one-sided mean grazing flow in two or three dimensions. By contrast to other simplified theoretical representations of a grazed aperture, the one proposed in this contribution considers some of the nonlinear effects a reduced order model should naturally inherit from the conservation equations governing the primary system’s dynamics. Furthermore, unlike other nonlinear developments, this one is able to reproduce the acoustic forcing amplitude dependence of the fundamental-frequency-based impedance, measured in recent experiments, without relying on empirical parameters. This nonlinear model offers further insight into the dominant physical mechanisms determining the aforementioned behaviour and allows reasonable a priori estimates of the aeroacoustic dynamics of the aperture. This could be used as a building block of more sophisticated systems or for the derivation of even simpler representations suitable for acoustic network modelling.
Prospects of indigenous fungi as novel biological control agents of thrips (Frankliniella occidentalis Pergande, 1895) on tomato (Solanum lycopersicum L.) in vivo

Published: July 2024

Tomato (Solanum lycopersicum L.) is an important horticultural crop in Kenya. Its production is constrained by many factors, among them arthropod pests and diseases. In response, farmers rely on synthetic pesticides, which lead to contamination of the produce, pest resistance and pollution of the environment hence there is need to identify safer, affordable alternatives. Biological control is considered safe, self-sustaining and cost effective. This study was aimed at determining the effectiveness of indigenous fungi in managing Western flower thrips Frankliniella occidentalis on tomato. Efficacy trials were conducted in farmer’s fields in Bungoma County, Kenya between March and November 2018. Treatments included fungal isolates Trichoderma harzianum, Gliocladium virens, Verticillium spp., Paeciliomyces victoriae and Fusarium oxysporum selected after in vitro screening. These were compared to commercial fungus Beauveria basssiana, a synthetic pesticide imidacloprid and untreated control. Treatments were replicated four times, arranged in a randomized complete block design. Data collected on population of thrips and the yield of tomatoes were subjected to Analysis of Variance (ANOVA). Means were separated using Student Newman-Keuls (SNK) test at p≤0.05. In the first season at Bukonoi, F. oxysporum significantly (p<0.05) recorded the least (38.1) mean number of thrips compared to the untreated control (89.2). At Cheptais, F. oxysporum and T. harzianum treated plots significantly (p<0.05) recorded the least mean number of thrips of 48.1 and 20.5 in the first and second season, respectively. Higher yields of 4.9 t ha-1 and 29.5 t ha-1 were obtained from plots treated with T. harzianum in the first and second season, respectively. The findings of this study demonstrated that F. oxysporum and T. harzianum have the potential to be developed as fungal biopesticides for management of thrips on tomato crop. However, large scale field trials are warranted to validate the effectiveness of these fungal isolates. Key words: Biopesticides, Frankliniella occidentalis, Fusarium oxysporum, Solanum lycopersicum, Trichoderma harzianum.

Published: July 2024

Lepidopteran stem borers are an important constraint to cereal production in Sub- Saharan Africa. The exotic Chilo partellus (Swinhoe) is one of the most economically important stem borer pest causing extensive losses on cereal crops in Kenya. This pest has also displaced indigenous species of stem borers while expanding its range in warm, mid and high altitude areas. In order to exert control on various developmental stages of this pest, both Cotesia flavipes Cameron (larval endoparasitoid) and Xanthopimpla stemmator Thunberg (pupal endoparasitoid) were imported and released in 2002 in the Eastern region of Kenya. This study was conducted to assess the establishment status, spread and impact of X. stemmator on C. partellus following its release in Kenya. Stem borer sampling was done on farms where the biocontrol agents had been released and on transects radiating outwards from them every 15km to assess spread. A total of 100 maize plants were inspected for stem borer infestation and destructive sampling done on 10 maize stems per farm to collect immature stem borer stages. Emerging parasitoids and adult moths were identified, counted and recorded. Results of this study showed that C. partellus was the most dominant stem borer species (constituted 71.2%) followed by Sesemia calamistis and Busseola fusca (26.0 and 2.8% respectively). A decrease in overall stem borer infestation (22.47±7.42%) with no significant difference across distances from parasitoid release points (F=0.4; df=3, 51; p>0.05) was also recorded. Seven parasitoid species were recovered, the most abundant being C. flavipes and this coupled with a significant increase in parasitism (25.27±3.27%) (V=1213, p˂0.05) from pre-release levels. The parasitoid of interest, X. stemmator was not recovered. This suggests a failure to establish though there is need to sample alternative hosts before this is declared.

Published: July 2024

The study was conducted on 75 Holstein cows imported from Germany to determine the chi-square value, the breeding value, the additive and dominance effect, and the effect of the allele of the HSP70 gene on the variation of total milk production and fat ratio. The HSP70 gene was divided into three bands, each with a length of 922, 935 and 932 bp. Molecular analysis of the gene shows the presence of 12-point mutations distributed in three primers (T825C, G856A, G937A, A1135G, G1185C, G1753A, C1867T, A2017G, C2548T, G2572T, G2688C and T2734C). Mutation T825C changed the amino acid Ata to Lie, and mutation G856A changed the amino acid Aca. to Thr. The result showed that the chi-square value was significant in the mutations (C1867T, A2017G and G2688C) reached (4.25, 3.90 and 4.16). The higher milk production in the CT genotype of the C1867T mutation was 5442.7 kg/season, the higher breeding value, dominance deviation, additive and dominance variance (652.3, 1460, 726856 and 235183) respectively for total milk production. The higher ratio of fat in the CT genotype of the C2548T mutation was (5.04%), and the higher breeding value, dominance deviation, additive and dominance variance (1.30, 1.70, 0.576 and 0.0793), respectively for the ratio of fat.
Radiocarbon dating of naturally shed reindeer antlers melted out of retreating and down-wasting ice patches and ice caps in western Norway
Authors: Nesje Atle
Published: July 2024

A rise in summer temperatures, especially since the turn of the 21st century, has caused negative mass balance and marginal retreat of ice caps and ice patches in western Norway. Twentytwo naturally shed reindeer antlers found at retreating and down-melting margins of fourteen retreating ice patches and ice caps on mountain summits in western Norway during the recent decades have been radiocarbon dated. The reindeer antlers show no evidence of being sawed or cut off the skull or any engravings/scrape marks if the antlers had been handled by humans. The oldest reindeer antler in this study dates at 2201-2132 cal. yr BCE. Four dated antlers fall within the age range 2300-2000 cal. yr BCE. Single dates fall within the time ranges 1100 to 1000, 900 to 800, and 500 to 300 cal. yr BCE. Four dated antlers are within the time range 200 BCE to 100 cal. yr CE and two dated antlers fall within the time range 600 to 800 cal. yr CE. Finally, fifteen dates fall within the time range 1300-1900 cal. yr CE, the highest number (n=11) between 1300 and 1600 cal. yr CE. The temperature decline and increased precipitation causing advancing glaciers and ice caps, accompanied by growing ice patches during the Neoglacial period, including the early phase of the Little Ice Age, provided good preservation conditions for the reindeer antlers during the Little Ice Age, with extensive ice and snow cover in the high mountains in western Norway.
Evaluating Citizen Science: Moving beyond Output Measures to Learner Behaviors, Interests, and Motivations
Authors: Olson Cheyanne , Colston Nicole
Published: July 2024

With the rising popularity of citizen science, there’s a growing focus on effective assessment methods for participant outcomes. Unlike many biodiversity programs, which typically emphasize programmatic outcomes, this study examined how Blue Thumb, an Oklahoma water quality citizen science program, influences volunteer behaviors, interests, and motivations using an explanatory survey based on Phillips et al.’s (2018) evaluation framework. Although there were no significant differences in behaviors and interests between new and experienced volunteers (N = 74), motivations varied significantly, distinguishing between intrinsic and extrinsic reasoning. Blue Thumb volunteers already displayed pro-environmentalism and strong scientific interests before joining, and these traits persisted rather than being cultivated through participation. The study’s insights informed Blue Thumb’s future volunteer recruiting and retention strategies. While contributing to research utilizing a common framework, future studies should incorporate qualitative methods to provide context for a deeper understanding of the quantitative findings.

Kompatybilizm teologiczny a problem Newcomba
Authors: Kuźniar Adrian
Published: July 2024

The paper examines and defends theological compatibilism — according to which human freedom is compatible with the existence of essentially omniscient God — against the background of a thought experiment known as Newcomb’s problem. It is argued that if a predictor in Newcomb’s situation is just a supreme scientist, it is rational to choose two boxes, but if he is essentially omniscient God, then it is rational to take one box only. The rationality of the latter choice is grounded in the truth of the conditional, “If S were to choose otherwise than S will, God’s past belief about S’s choice would have been different”. The truth of that backtracker does not deprive S of her ability to choose otherwise. On the contrary, it implies that God’s past beliefs about future contingencies counterfactually depend on the future. But if some part of the past counterfactually depends on our future acts, then there is no reason to claim that we are necessarily unable to do anything in the future such that if we were to do it, then that part of the past would have been different than it was. This kind of ability to control the past does not contradict the principle of the fixity of the past properly interpreted.

Since gaining independence, Pakistan and Turkey have maintained robust diplomatic relations. There are several connections that encompass trade, culture, spirituality, and similar values. The two fraternal nations have already been collaborating to enhance their commercial cooperation with the aim of achieving success in the global market and establishing trade agreements. Pakistan has had strong diplomatic relations with Turkey since its establishment. Both nations hold comparable perspectives on various global and regional matters. There exists a historical, religious, and cultural connection between Pakistan and Turkey. Both nations are situated in highly significant geostrategic regions and hold considerable importance within the Muslim world due to the robustness of their governments, economies, and military capabilities. Despite the mutual positive sentiments between Islamabad and Ankara, their efforts to foster robust economic and trade relations were unsuccessful. This study employs a chronological historical survey and a qualitative research methodology to examine the dynamics and rationales behind the evolution of bilateral interactions throughout history. Additionally, it examines the factors that have hindered the establishment of robust economic links between the two nations, including security concerns and the shared cultural and religious identities. This study will also examine the temporal stability of these factors and explore the potential implications and challenges that may arise from their future interconnections.

Authors: Feng Tingyu
Published: July 2024

This article delves into In this article, we conduct a comprehensive analysis of Environmental, Social, and Governance (ESG) Exchange-Traded Funds (ETFs) in the dynamic landscape of the Mainland Chinese market. The research categorizes existing academic perspectives into three distinct groups, evaluating whether ESG ETFs outperform, perform similarly, or underperform conventional ETFs. Employing a meticulous methodology, encompassing annualized volatility, daily average returns, Sharpe ratio, Information ratio, and tracking error, we delve into the nuanced performance metrics of these investment vehicles. The findings reveal a nuanced picture: within an annualized volatility range of 0.6% to 0.8%, ESG ETFs exhibit competitive performance, particularly demonstrating resilience in risk mitigation when market returns are negative. However, our analysis underscores crucial challenges in the current ESG landscape in Mainland China. The lack of clear ESG definitions and standardized evaluation criteria hampers a comprehensive assessment. Additionally, there is a notable disparity in ESG ratings for listed companies, adding complexity to accurate evaluations. Looking ahead, the study emphasizes the imperative of defining ESG standards clearly and establishing uniform evaluation systems and information disclosure mechanisms. These steps are essential to enhance the accuracy and reliability of ESG ETF evaluations, thereby fostering a more robust and stable investment environment. This research provides valuable insights for investors, policymakers, and market participants, illuminating the path toward optimizing the potential of ESG ETFs in the Mainland Chinese market.
Why Consumers Love Blind Boxes
Authors: Sun Fansu
Published: July 2024

With the increasing prevalence of the blind box economy, blind boxes have become a commonplace "necessity" in our daily lives, replacing their previous status as mere non-essential. Despite blind boxing becoming ubiquitous, there has been minimal research into the motivations behind why consumers are drawn to this trend. Against this background, this research will primarily utilize secondary data, complemented by a questionnaire survey, to analyse the factors driving consumers' fondness for blind boxes and analyze the factors contributing to the appeal of Blind Boxes, focusing on the popular Brand IP Marketing developed by Blind Box publishers and the "Blind Box-Funky Group" established by consumers. This study adopts the "STEPPS" theoretical framework and on this basis, also divides the reasons for the popularity of blind boxes into two aspects: user- perceived and blind box corporate offerings. It is found that Social currency and Emotions are the two main aspects of the popularity of blind boxes. Furthermore, our findings suggest that the external triggers that blind box companies intentionally create for consumers also contribute a lot. Our findings provide guidelines for the blind box companies in managing the rationale behind the Blind Box consumer market and offer fresh insights for its future development.

Published: July 2024

As a representative of the sharing economy model, the shared mobility industry provides people with additional mobility options to make their lives more convenient and offers possible options for future urban transportation paradigms. However, transportation problems in cities are still serious, and the role of the government in developing shared mobility and changing the future urban transportation paradigm remains unclear. This paper mainly adopts the literature method, takes the shared mobility industry as the research object, puts forward the hypothesis of the future transportation paradigm, and explores how the government should promote the formation of this paradigm. This paper bridges the gap in research related to the shared mobility industry and, at the same time, provides a reference for the government to promote the development of shared mobility, facilitate the formation of a new paradigm, and alleviate urban transportation problems.

Published: July 2024

In the International trades, trade barriers are common. However, regardless of how some countries may view the trade barriers, the tendency of world trade is still open and free. Besides, some international laws and treaties have regulated that states should promote the freedom of international trade, or it is against the obligations. Therefore, it is necessary to research on why international trade barriers exist and to give some suggestions to solve this problem. This paper conducted a literature review in the reason for international trade barriers. Four angles were being discussed: domestic political, income inequality, national security and culture influence. After examining 30 papers and law provisions, we got some conclusions. Reasons for international trade barriers are diverse, including the protection for states economy, security and the peoples interests. It also takes narrow nationalism and extreme patriotism and populism into consideration. To solve this problem, this paper suggests from the reform of WTO and some changes in the international treaties. On the other hand, this paper also has some advice to states to solve their domestic conflicts.
