Authors: Muvdi-Nova Carlos Jesús , Mora-García Said Andrey , Cáceres-Roa Sergio Alejandro
Published: February 2021

This research evaluates the effect of falling film vacuum evaporation on the characteristics of clarified acid bovine milk whey. The clarified acid whey was obtained by microfiltration (ceramic membranes, 0.2 µm cut-off, ∆TMP: 2 bar) and concentrated by a falling film evaporator. The clarified whey composition was mainly protein (0.32 ± 0.06 % w/w), ashes (0.56 ± 0.08 % w/w), soluble solids (5 ± 1 % w/w), and turbidity (16 ± 5 NTU). During the concentration step, the number of cycles changed notoriously for each volume reduction factor (VRF), being four the highest value achieved, with an average number of cycles of 18. The characteristics of concentrates were not affected by differences in the number of cycles, increasing proportionally with the VRF; it could be noticed in the final content that protein, ashes, and °Bx increased linearly around 3.5 times the initial composition. However, turbidity was different for each VRF because of heat treatment during the concentration stage (above 60 °C). A thermal treatment step after ricotta preparation would be advisable to remove the remaining protein. Tukey’s test was carried out at a 95 % CI, revealing statistical differences among means; therefore, there was a change in the characteristics of the final concentrated whey. Regarding color (absorbance), there were no considerable changes during the concentration process.

Published: February 2021

Background

A 12-lead electrocardiogram (ECG) is the most commonly used method to diagnose patients with cardiovascular diseases. However, there are a number of possible misinterpretations of the ECG that can be caused by several different factors, such as the misplacement of chest electrodes.

Objective

The aim of this study is to build advanced algorithms to detect precordial (chest) electrode misplacement.

Methods

In this study, we used traditional machine learning (ML) and deep learning (DL) to autodetect the misplacement of electrodes V1 and V2 using features from the resultant ECG. The algorithms were trained using data extracted from high-resolution body surface potential maps of patients who were diagnosed with myocardial infarction, diagnosed with left ventricular hypertrophy, or a normal ECG.

Results

DL achieved the highest accuracy in this study for detecting V1 and V2 electrode misplacement, with an accuracy of 93.0% (95% CI 91.46-94.53) for misplacement in the second intercostal space. The performance of DL in the second intercostal space was benchmarked with physicians (n=11 and age 47.3 years, SD 15.5) who were experienced in reading ECGs (mean number of ECGs read in the past year 436.54, SD 397.9). Physicians were poor at recognizing chest electrode misplacement on the ECG and achieved a mean accuracy of 60% (95% CI 56.09-63.90), which was significantly poorer than that of DL (P<.001).

Conclusions

DL provides the best performance for detecting chest electrode misplacement when compared with the ability of experienced physicians. DL and ML could be used to help flag ECGs that have been incorrectly recorded and flag that the data may be flawed, which could reduce the number of erroneous diagnoses.

Authors: Liu Zhiqiang , Feng Jingkun , Yang Zhihao , Wang Lei
Published: February 2021

BACKGROUND

With the development of biomedicine, the number of biomedical documents has increased rapidly bringing a great challenge for researchers trying to retrieve the information they need. Information retrieval aims to meet this challenge by searching relevant documents from abundant documents based on the given query. However, sometimes the relevance of search results needs to be evaluated from multiple aspects in specific retrieval tasks, thereby increasing the difficulty of biomedical information retrieval.

OBJECTIVE

This study aimed to find a more systematic method for retrieving relevant scientific literature for a given patient.

METHODS

In the initial retrieval stage, we supplemented query terms through query expansion strategies and applied query boosting to obtain an initial ranking list of relevant documents. In the re-ranking phase, we employed a text classification model and relevance matching model to evaluate documents from different dimensions and then combined the outputs through logistic regression to re-rank all the documents from the initial ranking list.

RESULTS

The proposed ensemble method contributed to the improvement of biomedical retrieval performance. Compared with the existing deep learning–based methods, experimental results showed that our method achieved state-of-the-art performance on the data collection provided by the Text Retrieval Conference 2019 Precision Medicine Track.

CONCLUSIONS

In this paper, we proposed a novel ensemble method based on deep learning. As shown in the experiments, the strategies we used in the initial retrieval phase such as query expansion and query boosting are effective. The application of the text classification model and relevance matching model better captured semantic context information and improved retrieval performance.
Bio Efficacy Assay of Laccase Isolated and Characterized from Trichoderma viride in Biodegradation of Low Density Polyethylene (LDPE) and Textile Industrial Effluent Dyes
Authors: Johnnie D. Alwin , Issac Reya , Prabha M. Lakshmi
Published: February 2021

This study is based on the biosynthesis of laccase enzyme from fungi Trichoderma viride and its exploitation in biodegradation of polyethylene using Laccase mediator system (LMS -Laccase + 1-HBT) in Low Density Polyethylene (LDPE) and in biodegradation of textile industrial effluent dyes. In different parts of our lifespan we have seen the numerous types of plastics are getting degraded by various methods, still the average time to completely degrade a plastic bottle is at least 450 years.Similarly industry produces over 3.6 thousand individual textile dyes today and utilizes more than 8000 toxic chemicals in numerous methods for textile manufacture comprising dyeing and printing. As polyethylene and textile industrial effluent dyes are causing severe hazardous effect on environment and health issues in all kind of living organisms, it is necessary to degrade plastics and textile industrial effluent dyes in rapid way. Recently researchers have come up with an idea of degrading plastic and textile industrial effluent dyes with the help of microorganisms and enzymes much faster than normal rate. The Laccase enzyme extracted was tested for its optimum temperature and pH. Lowry’s method is used for protein estimation. A control and sample LDPE was subjected to LMS. The tensile strength and elongation of the sample was less than that of the control after 5 days of treatment. This study showed that laccase together with 1-HBT helps to biodegrade polyethylene. The purified laccase enzyme was used for the pretreatment assay and post treatment assay. The Laccase degrades certain reactive dyes like Congo red, Acid Red, Methylene Blue, Brilliant Blue, Metallic Blue and Black. Thus recommends the application of laccase in textile dye colour removal (bioremediation).

The present research was conducted to characterize the indigenous plant growth promoting (PGP) Azotobacter strains isolated from plant root interface of semi-arid regions of Rajasthan (India) and to study their potential to be used as bio-fertilizers. A total of 172 Azotobacter strains were isolated, purified and based on the morphological test i.e. gram staining, pigmentation, cyst formation, fluorescence etc, broadly classified as Azotobacter. Further the secluded strains were examined for biochemical analysis and plant growth promoting characters. All the isolates showed different biochemical characteristics and significant PGP traits. IAA activity of the Azotobacter strains ranges from 54.5-6000 µg/mL. Ammonia, HCN and siderophore was produced by 92.4%, 78.4% and 80.23% of the total isolates respectively. Solubilization of phosphate was observed in 97.6% of the total isolates. These strains were also characterized for qualitative and quantitative N2 fixation abilities and the result indicated that 114 strains showed positive results on nitrogen free malate agar medium (NFMM) containing bromothymol blue (BTB) and able to produce 18.93-475.6 N-moles C2H4 mg protein−1 h−1 of acetylene reduced by Azotobacter strains. In vitro pot studies revealed that the selected native Azotobacter strains having high ARA results significantly increase the plant growth characters. Shoot length, root length, root number and chlorophyll content and leaf number increases by 45.62%, 17.60%, 97.49%, 49.69% and 27.83% respectively in pot inoculated with AZO23-3 as compared to control. These effective strains can further be utilized for development of effective microbial formulations.

Published: February 2021

While several researchers have suggested that evolution should be
explored from the initial years of schooling, little information is
available on effective resources to enhance elementary school students’
level of understanding of evolution by natural selection (LUENS). For
the present study, we designed, implemented and evaluated an educational
activity planned for fourth graders to explore concepts and conceptual
fields that were historically important for the discovery of natural
selection. Observation field notes and students’ productions were used
to analyse how the students explored the proposed activity.
Additionally, an evaluation framework consisting of a test, the
evaluation criteria and the scoring process was applied in two
fourth-grade classes to estimate elementary school students’ LUENS
before and after engaging in the activity. Our results suggest that our
activity allowed students to effectively link all of the key concepts in
the classroom and produced a significant increase in their LUENS. These
results indicate that our activity had a positive impact on students’
understanding of natural selection. They also reveal that additional
activities and minor fine-tuning of the present activity are required to
further support students’ learning about the concept of differential
reproduction. We also observed a low level of teleological predictions
for both pre- and post-tests.
A neutral fractional Halanay inequality and application to a Cohen-Grossberg neural network system
Authors: Kassim Mohammed , Tatar Nasser-eddine
Published: February 2021

We extend the well-known Halanay inequality to the fractional order case
in presence of distributed delays and delays of neutral type (in the
fractional derivative). Both the discrete and distributed neutral delays
are investigated. It is proved that solutions decay toward zero in a
Mittag-Leffler manner under some rather general conditions. Some large
classes of kernels and examples satisfying our assumptions are provided.
We apply our findings to prove Mittag-Leffler stability for solutions of
fractional neutral network systems of Cohen-Grossberg type.

Disentangling adaptation from drift in bottlenecked and reintroduced populations of Alpine ibex
Authors: Leigh Deborah , Lischer Heidi , Guillaume Frédéric , Grossen Christine , Günther Torsten
Published: February 2021

Identifying local adaptation in bottlenecked species is essential for
conservation management. Selection detection methods have an important
role in species management plans, assessments of adaptive capacity, and
looking for responses to climate change. Yet, the allele frequency
changes exploited in selection detection methods are similar to those
caused by the strong neutral genetic drift expected during a bottleneck.
Consequently, it is often unclear what accuracy selection detection
methods have across bottlenecked populations. In this study, simulations
were used to explore if signals of selection could be confidently
distinguished from genetic drift across 23 bottlenecked and reintroduced
populations of Alpine ibex (Capra ibex). The meticulously recorded
demographic history of the Alpine ibex was used to generate
comprehensive simulated SNP data. The simulated SNPs were then used to
benchmark the confidence we could place in outliers identified in
empirical Alpine ibex SNP data. Within the simulated dataset, the false
positive rates were high for all selection detection methods but fell
substantially when two or more methods were combined. True positive
rates were consistently low and became negligible with increased
stringency. Despite finding many outlier loci in the empirical Alpine
ibex SNPs, none could be distinguished from genetic drift-driven false
positives. Unfortunately, the low true positive rate also prevents the
exclusion of recent local adaptation within the Alpine ibex. The
baselines and stringent approach outlined here should be applied to
other bottlenecked species to ensure the risk of false positive, or
negative, signals of selection are accounted for in conservation
management plans.

Published: February 2021

Initially, the goal of Machine Learning (ML) advancements is faster computation time and lower computation resources, while the curse of dimensionality burdens both computation time and resource. This paper describes the benefits of the Feature Selection Algorithms (FSA) for speech data under workload stress. FSA contributes to reducing both data dimension and computation time and simultaneously retains the speech information. We chose to use the robust Evolutionary Algorithm, Harmony Search, Principal Component Analysis, Genetic Algorithm, Particle Swarm Optimization, Ant Colony Optimization, and Bee Colony Optimization, which are then to be evaluated using the hierarchical machine learning models. These FSAs are explored with the conversational workload stress data of a Customer Service hotline, which has daily complaints that trigger stress in speaking. Furthermore, we employed precisely 223 acoustic-based features. Using Random Forest, our evaluation result showed computation time had improved 3.6 faster than the original 223 features employed. Evaluation using Support Vector Machine beat the record with 0.001 seconds of computation time.

Published: February 2021

The mutual help or soyo practice, which has relevance in modern management systems, is an effort to strengthen the local wisdom values in urban communities that tend to rely on cultural mechanisms. This research aims to show the cultural mechanism that still survives in Javanese urban communities concerning modern management systems development. Meanwhile, the analysis performed was based on data obtained through interviews, observation, and documentation methods. The research showed that soyo is a local tradition that emphasizes the survival of solidarity bonds and mutual help or ta’awun. Furthermore, the practice describes the efforts to maintain community cohesion and solidity amid life’s complexities. The mutual help principle in soyo has also proven to assist the community in achieving goals without fully relying on economic capital and other parties’ intervention, especially from the state. Therefore, a modern management system should be open to the local wisdom values in reflecting how to achieve these goals.

Published: February 2021

The turnover rates among millennial employees have become serious issue for many industries including healthcare industry. The negative economically outcome due to high turnover rate can vary from direct and indirect, tangible and intangible cost to the organization.

The cause of high turnover rate has been explained in many literatures, which includes leadership as one of the factors. Many studies have been underlining the importance of leadership style in lowering the number of turnover. Albeit some of leadership style may be proven to be effective in certain organization, the shift of millennial characteristic pressed other scholars to analyze if current theories of leadership style may sufficient and fitting to millennial. Therefore, there has been a gap in the literature between leadership style and leadership traits.

The purpose of this research is to study the relation between effective leadership traits for managing millennial and its’ impact to lower millennial healthcare workers turnover intention. Teamwork is an important aspect in millennial setting; therefore, it is used as moderator to imply if teamwork may strengthen the relation between the two previous variables.

The study was held in a small-scale maternity hospital in Malang, Indonesia, with the population of 57 millennial employees. The results of this research effort may help to fill the gap in the literature about the relationship between leadership traits, teamwork, and employee’s turnover for millennial in the workplace; and will hopefully help the organization to understand better the millennial motives to stay, and to bridge understanding between employer and employees.

Quantification and Analysis of Uncertainties in Parameters of Rotors Supported by Bearings
Authors: Da Costa Caio C. O. , Da Costa Cesar
Published: February 2021

Rotating unbalance is one of the most important critical parameters that causes operational failures of rotating machinery. The uneven distribution of mass on the structure of the rotors creates heavy spots, which must be eliminated to avoid generating excessive stress on the rotor bearings. The main objective of this work is to perform the uncertainty analysis on rotating machine systems supported with rolling bearings. A computational procedure is implemented to achieve this objective that can qualitatively represent the main behaviors and parameters of rotating machines. Further, methods of uncertainty quantification are applied to verify the behavior of the system given the probability density functions of the input parameters. One of the most commonly used methods is the Monte Carlo method, which requires thousands of simulations to produce accurate results. This method is used to obtain means and standard deviations of the system responses, given the means and standard deviations of the inputs. In our work, Monte Carlo simulation has been successfully used as a reference stochastic solver to evaluating the variability of the dynamic responses.
Sounding Rocket Preliminary Design
Authors: Zosimovych Nickolay
Published: February 2021

This article aims at studying sounding rocket (SR) class, or those vehicles launched from the earth and carrying out various experiments at high altitudes. After the end of their mission, rockets should deliver a payload to a given point or to give range.
In general, design tasks are divided into direct and inverse ones. This paper focuses on direct designing tasks. In this respect, the set values are maximum range, payload mass and restrictions on the sounding rocket construction. As a result, a SR general design technique is proposed. This technique includes selection of the SR initial parameters, the number of stages, the relative weights of the fuel components, the specific thrust of the engines for each stage and the initial transverse load on the SR.  After selecting the fuel composition, engine design features and rocket as an object, the starting mass can be represented as a complex mathematical function. Moreover, predetermined maximum range, rocket payload, selected fuel components, structural design, materials, design parameters allow for a definite SR weight determination. Finally, overall and power characteristics of the SR are proposed within this technique. Such characteristics are accepted as design parameters.
Alcohol Use among Medical Students: Linking Knowledge as a Social Capital Defining Norms in Learning Institutions
Authors: Njagi Patrick N. , Midigo Ronnie
Published: February 2021

College alcohol use continues to be a national public health issue. World Health Organization approximates that 53% of people at the age of 15 years and above, have at one time used alcohol. Alcohol is recognized and acts as ‘entrance’ to the use of other substances. The study was carried out in Kenya Medical Training College, Embu Campus. The study presents an argument that knowledge about alcohol is a social capital defining use and non-use of alcohol among medical students at Kenya Medical Training College. A Cross-sectional analytical approach was adopted for the study design. A sample of 270 students was included in the study. Data was analyzed using both descriptive (Frequencies and percentages) and inferential statistics (chi square tests and regression analysis). For objective one, the study finds a 75% prevalence rate of alcohol use among students of Embu MTC. Demographic factors influencing alcohol use include, religion (p=0.002205), program undertaken (p<0.0001) and with whom the respondent is living with (p<0.0001). The study recommends development and implementation of policies and programs aimed at addressing the widespread use of alcohol in the study site.

Published: February 2021

The widespread use of tobacco among people living with HIV (PLWH) has a significant impact on morbidity and mortality. However, gender differences in cigarette smoking and its consequences among PLWH have not been documented. For these analyses, we included 470 PLWH smokers (255 males and 215 females) actively followed in a randomized clinical trial. A comprehensive smoking and medical profile were obtained along with FEV 1 to assess if lung function and subsequent reduction differed by gender. Almost half of the participants were females (47%) and were slightly younger than their male counterparts (49±9 vs. 52±9 years, p=0.009). Smoking onset was similar (17±7 vs. 18±7 years of age, p=0.1), as well demonstrated preferences for mentholated cigarettes (women 89% vs. men 85%). Based on pulmonary function testing, females had a significantly lower percent predicted forced expiratory volume in one second (FEV1= 1.38) versus 1.9 in the male counterparts. Furthermore, women had a greater reduction in FEV1 over time. Among a clinical sample of PLWH smokers, we demonstrated significantly greater manifestations of lung damage in females compared to male smokers. Collectively, these findings further justify the need for more studies to closely monitor and tailor interventions for women.

This association causes detrimental impacts on child health and around 68% global population today are affected by it. T2DM is initiated in children with obesity as insulin functioning is resisted, which further leads to an inflammation and damage in the pancreas leading to adverse effects in later stages of life. Many scientific studies have been conducted to understand this link and does Body Mass Index (BMI) contribute to this epidemiology and complications related to T2DM and Obesity in children. Alarming effects, both physically and internally on the pancreas are observed because of these conditions and also causes fat deposition in the body organs like pancreas leading to increased Body Mass Index (BMI) and Waist Circumference (WC). This association can be caused due to genetic factor during infancy, but this has still not been validated as relevant researches are still underway. Important studies like SEARCH for Diabetes in Youth have contributed to giving important and useful findings about this association but still much needs to be achieved to make future progress in overcoming this burden on child health and ensure that Sustainable Developmental Goal (SDG) 3 is achieved at a global level.

Platelets play a pivotal role in coagulation, or clot formation, resulting in haemostasis, after endothelium injury. Disturbance of platelet activation may lead to pathologic thrombosis. Platelet activation and aggregation are common factors in atherothrombotic events, critical in the atherothrombotic process, and cardiovascular diseases. Several drugs are being used for antiplatelet therapy to prevent and/or treat atherosclerosis and cardiovascular diseases. Synthetic antiplatelet drugs hold possible undesired health consequences (cardiovascular diseases, carcinogenicity, etc.), advocating their replacement with natural, effective, and non-toxic compounds. Many phenolic compounds are created as secondary metabolites of plants, are found in many fruits and vegetables, and constitute a wide family of high-added-value molecules. Their biological activities include antioxidant, anti-platelet, and anti-inflammatory action. Based on the above, we examined five phenolic compounds (ellagic acid, ferulic acid, gallic acid, quercetin, and kaempferol) for their effect on platelet reactivity in whole blood samples using flow cytometry.

Quantification of activated platelet marker CD62-P by flow cytometry showed that all five compounds inhibited platelet activation in vitro, induced by adenosine diphosphate (ADP) and collagen. Interestingly, based on the IC50 values obtained for expression of CD62-P, among ellagic, ferulic, and gallic acid, gallic acid showed significantly higher inhibition than the other two. Kaempferol found to be a more potent inhibitor than quercetin, following previously reported results from aggregometry. Results obtained from our flow cytometry screening indicate antiplatelet activity from novel phenolic compounds and their potential use as drugs for thrombosis and cardiovascular diseases.

The existence of regional autonomy, one of which is trying to provide the best quality service and helping the welfare of local communities with regional capabilities in managing their own regions. But in reality, regional autonomy does not provide equitable publik services, this is because Garut Regency has a large area and a large population and is not balanced with the capacity and resources of the local government in serving the community. The purpose of this study is to determine the expansion of the New Autonomous Region of South Garut Regency as an alternative to realizing the effectiveness of publik services. The method in this research uses a descriptive qualitative approach, collecting data through interviews. Interactive model of data analysis techniques consisting of data reduction, data presentation and increasing conclusions. The results of this study are the division of South Garut Regency is an appropriate and fast alternative as an effort to provide effective and optimal publik services in overcoming development disparities. The conclusion of this study in terms of speed, the expansion of South Garut Regency can help accelerate the services provided by the local government with the support of adequate human resources and infrastructure. In terms of accuracy it helps in providing services that reach all corners of the village and on targeted budget allocations. In terms of convenience when it makes it easier to serve the community because of the government offices that are close to access that is accessible to the community. In terms of justice, the large population is balanced with the number of government agencies / offices in the South Garut region.

Before the emergence of Covid-19 which developed throughout the world, the Indonesian Central Government had issued Law Number 6 of 2014 concerning Villages, which is a policy that regulates the level of Village administration. However, in this law there is no allocation of development funds and village empowerment which is the basis of the community at the level of village government administration (Gampong). Funds sourced from APBN, APBD Province or Regency, hope to support the progress of the village to become an independent village capable of organizing and managing. The allocation of village funds in the form of a Village Revenue and Expenditure Budget (APBG) is directed to finance government activities, development and community empowerment. For this reason, the Government has issued a special policy to handle Covid-19 by allocating Village Funds to address problems arising from the Covid-19 pandemic. Especially for the economic sector through the formation of Village-Owned Enterprises (BUMG) which is a business driver to improve the quality of life and realize the welfare of rural communities. With a descriptive qualitative approach using three methods, namely observation, interviews and documentation analysis. This study aims to determine business potential with local wisdom through a SWOT analysis with a focus on Village-Owned Enterprises. Based on the SWOT analysis, in the end, Village-Owned Enterprises will facilitate activities in realizing plans in accordance with local wisdom for the welfare of the community, especially in the era of the Covid-19 pandemic.

We studied the effect of the cereal aphid (the bird cherry-oat aphid Rhopalosiphum padi L. and grain aphid Sitobion avenae F.) infestations on the oxidative damages of protein in the maize (Zea mays L., cultivar Touran) seedlings. We found that the content of protein thiols and protein bound carbonyls were dependent from study factors: time of feeding, the number of aphids and species. In relation to uninfested plants (control), prolonged insect (R. padi and S. avenae) feeding (24–96 h post infestations) was linked to depletion in levels of protein thiols in foliar tissues of maize genotype and accumulation after 96 h post infestations in maize seedlings investigated by higher number of aphids, protein bound carbonyls. Our results indicated that the biotic stress factors, including aphids evoke the oxidation of protein in the maize. The stronger protein damages occurred in the maize seedlings infested with oligophagous R .padi females.
