This study aims to evaluate the ultrastructure of the muscle and bioaccumulation of heavy metal elements in Oreochromis niloticus muscle as a biomarker of environmental pollution in post-coal mining ponds. The fishes sample come from three different ponds, namely from the Control pond,Senong pit (5 years old), and Goldstar pit (10 years old). Heavy metal elements in fish meat were analyzed using Scanning Electron Microscopy combined with an Energy Dispersive tool X-ray (SEM-EDX). The results showed that the level of accumulation of heavy metals (K, Cu, Zn) in fish samples with the highest percentage of metal elements was Cu between 1.48-1.74%; Zn between 0,80-1.17% and K between 1.58-2.43%. Histological lesions in the muscle tissue of Tilapia, O.niloticus are in line with the accumulation of the metals. The levels of Cu, Cl, and K in muscle from Control are lower in longer ponds, highest Zn percentage in old ponds. These results provide evidence that microanalysis of metal elements in tissue with SEM-EDX and fish muscle ultrahistopathology as biomarkers can be used as an indicator of pollutant exposure in post-coal mine land waters. The findings of this study are expected to be used as consideration in the aspect of diagnostic methods in monitoring fish health status and quality of fish products originating from post-mining ponds.

In addition to broad support for object-oriented (OO) adaptability, it is difficult and challenging for students to master the basic OO concepts. This suggests the need to improve research to identify cognitive difficulties for minimizing the dropout ratio of students in programming courses as well as improve overall learning performance. In this paper, the competency model is designed for determining the major competencies required for mastering the skill of OOP. The competency model is also used as the expected learning outcomes intended to achieve for learning OO. The survey is conducted to identify the difficulties that are attained at each specific level of competence. The results of the student's observation of the completed task indicate that for students, identifying classes, defining states and behaviors, associations between classes, creating objects from specific classes, and other basic OO features in a given problem scenario are challenging for the students to be masters in. In addition, the results of student feedback indicate that improper feedback on high-cognitive topics, lack of comprehension of basic concepts, and difficulties in teaching methods have become the main reason for students' lack of interest in learning OO. The findings of this paper would be helpful for educators to reduce the difficulties by providing simplified teaching methodology or any an interactive learning environment.

Psychopathy has taken its due stake in research; while the curiosity in this area is still growing corporate psychopathy has emerged as a new area of research. The psychopaths working in organizational settings are called corporate psychopaths. These corporate psychopaths are prune to manipulation, are attracted to status, power and money. Typically found in higher positions in organizations, these snakes in suites can cause damage to organization such as large scale frauds. Numerous researchers have recognized the connection among psychopaths and moral emotions. Bulk of research work have vocalized about self-directed negative signals of psychopaths (guilt, regret, remorse, shame , embarrassment) and negative signals directed towards others ( anger, rage, indignation, contempt, disgust, resentment, scum, envy, jealousy, schadenfreude). Nevertheless, we found sparse equal to none research related to corporate psychopathy and positive signals such as pride. Taking lead from this significant research gap, we reviewed the literature related to the corporate psychopaths and one of the self-directed positive moral emotions (pride) and conceptually link both the emotions of pride and corporate psychopathy. Eventually we proposed a conceptual framework. We suggested that corporate psychopaths are false diviners; due to their Narcissistic personality and nature have an authentic and hubristic pride. Authentic and Hubristic pride are prides which is the darker sides of pride, bursting with false self-worth, ego and self-deception. This conceptual framework is a fist of its kind and a feed for thought for future researcher. We also have proposed research directions for future researcher.

A linear pattern is one in which the number of items decreases or increases over time. This data appears as a straight line angled diagonally up or down on a graph (the angle may be steep or shallow). As a result, the trend may be either upward or downward. These techniques or patterns are being used to collect the data of the articles. Making use of the Annotated Bibliography it has been discovered that various patterns and different Big Data algorithms that are being used in healthcare to predict the disease and then give the medicine according to that data collected for the disease. Some gaps have been identified in the literature review; the central gap was that there was no Convolutional Neural Network (CNN) in the articles. This is the most updated technique that is being used to recognize the disease based on images. For example, if we have the data of ten thousand x-rays. We have put that all the data in the system and then perform different algorithms. Our prediction system will predict that on behalf of this x-ray, what is the disease to this person.Various steps or techniques can be used to expand the current annotated bibliography into more extended literature. CNN technique can be used to identify the patients' disease on behalf of x-rays or any image. To implement this, we need to collect public data; we will be using public data because it is verified data. We will require around ten thousand+ datasets, and then we have to perform different algorithms so that our prediction system will work accurately.

This research is aimed at the dynamic management of SPM on a single processing core. A dynamic SPM dynamic management strategy based on random sampling is proposed. The dynamic memory access characteristics displayed during the execution of the program and are used to manage SPM and make the SPM management free from depending on Profiling information and compilers. The difference between this method and the traditional SPM management strategy is that it utilizes the hardware support provided by DataUnit, and performs complete runtime management of SPM through software and hardware coordination, which can better reflect the dynamic changes of program access during program execution. . Furthermore, this paper extends the random sampling SPM allocation algorithm to a multi-tasking environment, simulates the multi-tasking environment by modifying the small real-time operating system RTOS, and designs a multi-task test program set based on RTOS as needed. The performance of SPM is performed using a random sampling algorithm in the single task environment.

The Earth has been facing a lot of climate change lately due to global warming. This gives rise to being more innovative with our waste and start recycling and producing it into another substance that would also help us in terms of agriculture. Since there is also an ongoing pandemic that is happening it is also best to stay at our households and start practicing healthy living. This study assessed the effects of organic fertilizer made from chicken manure, carbonized rice hull and mud press with microbial inoculant on the growth and yield performance of the mungbeans. To determine what composition of organic fertilizer (OF) and garden soil (GS) would give a better or best growth and yield performance of mungbeans, treatments with varied proportions were tested with T0 (100% GS), T1 (25% OF + 75% GS), T2 (50% OF + 50% GS), T3 (75% OF + 25% GS) in plot beds with three replicates using Randomized Completed Random Block (RCBD) design. Results showed that T2 produced the highest plant height, most numbered leaves and branches. Analysis of Variance (ANOVA) test indicated a significant difference in the number of pods per plant between treatments but no significant difference in the number of seeds per pod and the weight of 1000-seeds. Post hoc test revealed that T2 produced best yield performance of mungbeans in terms of the number of pods per plant. This suggests that among the treatments of organic fertilizer, its suitable mixture with garden soil is 50%-50% giving a very high significant difference (p<0.000) of yield performance compared to the other treatments in the study.

This study explored the long-term retention of basic science knowledge and the ability to understand and make use of basic science in explaining a clinical scenario in the final year of medical school. A sample of 54 senior health science students was reassessed using the same human anatomy examination paper they had taken 3 years earlier. This was followed by an in-depth interview on one of the topics taken from the test. Their respective level of knowledge was compared with their performance in the interview. The test was analyzed according to the revised Bloom’s Taxonomy, and the interviews carried out according to the phenomenographic approach. The findings of the study depicted that there was poor retention of knowledge among health science students. Whereas the comparison among the health science disciplines, the findings showed that there was no difference in knowledge retention among the physiotherapy, nursing and traditional Chinese medicine students. Findings suggest a substantial loss of basic science knowledge during clinical training. Attention should be directed to designing assessment methods that are purposeful for health science graduates as well as how that knowledge should be acquired and retained lifelong throughout their clinical practice.

Aquaculture provides a large business opportunity along with the large demand for fish. One problem is the presence of pathogenic bacteria that attack cultivated fish. The use of synthetic antibiotics has been increasingly reduced and returned to natural antimicrobials. The use of natural anti-microbes has great potential to be developed. One of the things that can be used is secondary metabolism of heterotrophic bacteria which is widely spread in the waters. This study aims to determine the ability of secondary metabolite production of heterotrophic bacteria to inhibit the activity of pathogenic bacteria (Vibrio alginolyticus, Aeromonas hydrophila and Pseudomonas sp).The method used is the experimental method. 10 Heterotrophic bacterial isolates obtained from the collection of marine microbiology laboratories were cultured on Nutrient broth media for 7 days and penned during stationary times, then extracted from secondary media from the media and shells using Etyl Acetate. The secondary metabolite extract was tested against 3 pathogenic bacteria that usually attack fish.Based on the results of the antagonism test conducted, 10 heterotrophic bacterial isolates were able to inhibit the growth of all three pathogenic bacteria. The strength of the inhibition in Vibrio alginolyticus varies between 6.8 - 11.76mm, The strength of the inhibition in Aeromonas hydropila bacteria ranges from 6.8 to 9.5 mm, the strength of the inhibitory strength in Pseudomonas aeroginosa bacteria varies between 6.7-11.1 mm. Overall the inhibition of the three strongest pathogenic bacteria was N isolates (Bacillus cereus code access KM489154.1). and the weakest is Q isolate (Bacillus cereus, code access KY750689.1. Conclusion. Heterotrotic bacteria produce secondary metabolites that can inhibit the growth of pathogenic bacteria in fish. Secondary metabolism of heterotrophic bacteria has the potential to be developed as an anti microbial in pathogenic bacteria in fish..

Citrus is one of the significant fruit crops worldwide and also grown in Pakistan provinces. Punjab produces above 95% of this fruit crop due to a conducive growing environment. The citrus production gap is linked with numerous factors; the main factor is insects and diseases of citrus fruits. In this respect, the main problem is fewer responsiveness of farmers about citrus canker disease. At the time of need, farmers are not capable to achieve the demands of the citrus fruit, so make a vast gap in citrus manufacture. Citrus canker is an excessive disorder, the pathogen, normally characterized through visible rough scratches on fruit, stems and leaves, twig dieback, falling off undeveloped fruits and trees and defoliation. The aim of the current study was to identify the farmer’s awareness about the citrus canker disease and pest control measures. Therefore, the current study conducted in Tehsil Jaranwala, District Faisalabad. From the selected tehsil one union council was selected through purposive sampling technique and from eight villages of the union council (UC-15) citrus growers were selected which made a collective sample size of 120 respondents. A face-to-face interview was conducted for the collection of data. The results of the study presented that the majority of the respondents were growing Kinnow. Farmers suffering from many constraints as the majority of citrus growers faced citrus canker disease. Results indicated that research organizations, citrus development projects and newspaper were more effective source of information in order to control citrus canker disease. Respondents faced a lot of constraints regarding plant protection measures, these were non-availability of tube wells, expensive pesticides, spraying material due to high prices, lack of knowledge and less cooperation of extension workers. It is concluded from the current study that the growers need the training to increase the technical knowledge, finance for investment and pure chemicals for better protection. Growers were more dependent on conventional methods instead of bio-control. It is urged to the responsible sectors to create an awareness campaign should be launched regarding the effective control of the citrus canker disease and imparted the technical skills among growers to control it in an effective way.

The recent oil spill incident in coastal area of Karawang Regency in West Java, Indonesia spread to the surroundings coastal waters of Bekasi and Seribu Islands. These coastal waters are connected and are fishing ground of most artisanal fishermen in these coastal area. It is, therefore worthwhile to examine the fish quality collected from the exposed area after the incident. This study was carried out to provide information on heavy metal concentrations in the muscles of several fish species, including crabs and shellfish. The fish, crabs and shellfish samples were collected with the help of local fishermen. The concentrations of Arsenic (As), Cadmium (Cd), Mercury (Hg), and Lead (Pb) were determined in the muscles of collected fish, crabs and shellfish. The concentration of heavy metals were measured in the laboratory by atomic absorption spectrophotometry after digestion of the samples using kjeldahl heating digester. The results showed the concentration of all metals in the present study were lower than the limits permitted by Indonesian national standard. Therefore, it seems that no problems on human health would be raised from the consumption of the collected fish from the Karawang, Bekasi and Seribu Island coastal waters, from the heavy metal content point of view.

The assessment of the aquatic environment condition is only by taking a sample of water quality, sometimes not clearly showing the actual alteration. Thus, to find out more about pollution conditions such as the presence of heavy metals in aquatic ecosystems, it requires to be supported by other types of samples, such as metal content in benthic biota and aquatic sediments. This study aimed to analyze the content of heavy metals in green mussels and crabs in the coastal area of Karawang - West Java which is suspected to often receive a variety of pollutants from potential industrial activities resulting in heavy metal contamination. In addition, the two types of benthic biota are often consumed by the community so that the feasibility or safety based on heavy metal content is also important to elaborate. Sampling was focused on 2 locations that often experienced a drastic increase in the abundance of green mussels, namely Sungaibuntu and Cemarajaya Villages. The results of sample analysis showed that Cadmium (Cd), Lead (Pb), and Tin (Sn) were below the detection limit for all samples. Arsenic (As) content was relatively higher in shellfish samples, while Mercury (Hg) levels were higher in crab samples. If viewed from the location of live shells in the water column (with the help of artificial substrate) and crabs in the bottom of waters, the metal content in both samples indicated that Hg accumulated more quickly in the bottom waters whilst As can lasted longer in the water column. When viewed from the viewpoint of consumption eligibility, all heavy metal content in the samples of shells and crabs in the study site still meets the requirements for consumption eligibility based on SNI 7387: 2009 [1].

In WSN the nodes are equipped with restricted power, communication range, and computation power. The WSN sense the data at regular cycles and forwards the sensed data to the BS. The sensor node transmits data at regular intervals, when most of the times it is unnecessary. To limit the excessive data transmission proposed a time critical threshold based protocol, which use a specific parameter which is triggered only when the sensed threshold value meets the time critical based on high priority. Experimental results proved that our proposed protocol has outperformed the former one in terms of stable and unstable period.

In this paper, we address the influence of zinc (ZnO) nanoparticles (NPs) on the AC breakdown voltage (BDV) and acid number (AI) of palm kernel oil methyl esters (MEPKO). To determine this impact, several samples with different concentrations of NPs are prepared by homogenizing the mixtures with an ultrasonic homogenizer. The measurements of breakdown voltage and acidity index are made respectively from the ASTM D1816 and IEC 296 standards. These measurements are made both before and after the addition of zinc nanoparticles. The results obtained allow us to conclude that the acidity index of the MEPKO increases by 320% for a concentration of 0.10% ZnO. For concentrations of 0.15% and 0.20% ZnO, there is an increase of 183% and 116% with respect to the AI of the MEPKO For BDV, there is a recovery of 8% and 3% for 0, 10% and 0.15% ZnO concentrations respectively. For a concentration of 0.20% ZnO, there is a 9% increase in the BDV of MEPKO. This analysis shows that the addition of ZnO to MEPKO has a negative impact on their AI. This is not the case for their BDV which are at two concentrations (0.10% and 0.15%) decreases before increasing for the concentration of 0.20% ZnO.

In this paper, experimental and numerical studies were carried out to investigate the performance of normal concrete (N.C), polypropylene fiber concrete (P.F.C), steel fiber concrete (S.F.C), and high strength concrete (H.S.C) filled steel tubes under lateral impact loading.A total of eight specimenswere tested divided into two groups, four specimens for each for the four types of concrete. The first group the specimen’sdimension were 114.3 mm diameter and 4 mm thickness, and the other group with dimension of 88 mm diameter and 4 mm thickness. The average cubic strength for all concrete was Fcu=45 N/mm2, except for the high strength concrete wasFcu=70 N/mm2. The specimens were tested using drop-weight impact test rigs with fixed- sliding boundary conditions at ends.The parameters studied were types of concrete,the length to diameter aspect ratio, and the confinement factor effect.The failure mode and local damages of the specimens were thoroughly investigated.A finite element analysis (FEA) model was also performed to simulatethe performance of (CFST) members against lateral impact loading and the predicted resultsfrom the FEA model were validated with the corresponding experimental results.Wide range analyses of the (CFST) specimen’sresponse against impact loading were then carried out using the validated FE models to examine the deformation and the energy dissipation of each concrete type.The main findings are as follows: (1) The lowest value for the total impact energy and maximum dynamic displacement were recorded for all specimens filled with polypropylene concrete specimens. While the maximum recovery energy was observed for the same specimens in group (I). (2) Nearly the same value for the total impact energy and maximum dynamic displacement were recorded for the specimens filled with ordinary concrete and high strength concrete, which mean that no benefit was gained form increasing the concrete strength.On the other hand, it may have triggered brittle failure for the concrete core. (3) high strength concrete specimens has The lowest values of constraining factor (ξ) , which behave in the most brittle failure pattern. so, Ductility of the tested specimens increase with the constraining factor (ξ).

Raga Similarity had been a topic of fascination among Karnatik music followers. Though the topic remains active and interesting, a lack of appropriate similarity quantification method leads to subjective interpretations which in turn can be ambiguous intermittently. In this paper, we propose a raga similarity method, RagaDist, that quantifies similarities between raga pairs, based on their semantic structure and classifies the similarity into a 4-scale measure. Similarities derived using RagaDist is compared with popular string similarity methods using clustering approaches – Hierarchical clustering and Partition Around Medoids (PAM) and Multi-Dimensional Scaling (MDS) methods to analyze emerging patterns and characteristics among Melakarta raga similarities. Empirical measurements were conducted using one-way ANOVA and post hoc analysis. We also determined that using RagaDist, a threshold of 0.79 may be used as a cut off to distinguish ragas based on similarity.

This work proposes a satellite based Cyber-Physical System for impact analysis of wildfire. Wildfire can may occur due to human activities or natural phenomenon such as lightning and have substantial impact on living beings and the environment. Analysis of Australia wildfire shows a drastic change in vegetation and atmosphere of Australia. Biomass burning is one of major source of emission of pollutants. The major air pollutants are carbon dioxide ( ), carbon monoxide ( ), nitrogen dioxide ( ), ozone ( ), sulfur dioxide ( ), formaldehyde ( ) and particulate matter (PM). To monitor air quality, we have to investigate the extent of these gases in air. Traditional method involving installation of embedded systems-based air quality measurement equipment are too much costly and have limitations as it can be installed in a limited area. Satellite-based Cyber-Physical System is an alternate technique for detecting damages caused by wildfire. This paper aims to investigate impact of wildfire on atmosphere and vegetation of Australia, through Satellite-based Cyber-Physical System, while employing Sentinel-5 Precursor (Sentinel-5p) and Landsat 8 satellites using Google Earth Engine. Using our proposed Cyber-Physical System, we processed pre-fire dataset (2019-11-05 -to- 2019-11-07) and post-fire dataset (2019-11-08 -to- 2019-11-13) of Sentinel-5p and Landsat 8 in utilizing Google Earth Engine. Our analysis shows a severe decrease, of nearly 100%, in healthy vegetation and drastic increase of almost 112% in , 260% in , 264% in aerosol index, 144% in in New South Wales and its nearby cities of Australia. Our analysis proved that as compared to up-to-date fire monitoring systems, our proposed Satellite-based Cyber-Physical System have a great potential in making critical decisions and shows appreciable performance in productivity, safety, reliability and serviceability.

Satellite based remote sensing technology is one of the emerging fields due to their proven significance. This work proposes a sophisticated satellite-based remote sensing system for analyzing tropospheric , that spans from surface up to 10km. The major source of tropospheric is the anthropogenic activities, such as the combustion of fossil fuels including coal, gas and oil and natural processes comprising lightning and soil processes. is one of the major air pollutant and source of acute health effects. In this article, we propose a satellite-based CPS along with the Google Earth Engine (GEE) as our data processing engine. Sentinel-5 Precursor (Sentinel-5p) satellite of European Space Agency (ESA) was utilized to remotely sense temporal atmospheric concentration. In order to investigate the utility of our proposed CPS, we focus on Pakistan as our study region. In order to analyze the disparity in tropospheric during COVID-19 using our proposed satellite-based CPS, we consider pre lockdown period from 10th February 2020 to 21st March 2020, while the observed lockdown period spans from 22nd March 2020 to 12th April 2020. Most of the anthropogenic activities such as public transport, industrial operations were halted due to COVID-19 lockdown in Pakistan. This resulted in a very drastic decrease in the observed atmospheric concentration. This article analyzes the concentrations in Pre-lockdown and during-lockdown in all the major cities of Pakistan. The obtained results show a drastic decrease in concentration, especially 83% reduction in the case of Karachi and the lowest decrease of 51.2% in Gujranwala. Furthermore, our pre-lockdown and during-lockdown analysis show a decrease of 43.3% in the target pollution in the whole country. We also analyzed China and Italy tropospheric using deployed CPS and detected a total decrease of 63.8% in China and 36.9% in Italy tropospheric , respectively.

This work presents electrodynamic bridge energy harvesters (ED-BEHs) for bridge monitoring systems application. Two multi-mode type ED-BEHs are developed for low frequency and low acceleration bridge’s vibrations. ED-BEH, prototype-1, is composed of a split beam having a gap along the length in which a central beam is attached from its free end and running back towards the beam’s fixed support. Two magnets are mounted at the free ends of the split and central beams which are allowed to vibrate inside hollow cylindrical wound coils. However, in ED-BEH, prototype-2, both the split and the central beams are attached to the same fixed support. Magnet is mounted on the central beam, whereas, wound coil is placed in the coil holder attached to the split beam, moreover, the axes of magnets and wound coil are oriented along the beams’ length. Both prototypes are simulated in COMSOL multiphysics for determining the resonant frequencies and corresponding mode shapes. The developed harvesters are characterized under harmonic excitations of low frequency and acceleration levels. When subjected to 0.09 g acceleration, prototype-1, at the first resonant mode (4.4 Hz) produced a maximum load voltage of 0.6 V and power level of 2.51 mW at coil-1 and a maximum voltage of 1.2 V and power level of 10.7 mW on coil-2 at the second resonant mode (5.5 Hz). However, when prototype-2 is applied to 0.07 g acceleration, it generated a maximum voltage of 2.7 V and power of 13 mW at the first resonant mode (3.2 Hz) and at the second resonant mode (4.2 Hz) a voltage of 3.1 V and power of 7.8 mW. Furthermore, the AC output voltage of the prototypes are also converted to the DC voltage for the bridge monitoring system applications.
