Authors: Salas Ibarra Martín Eduardo , Basante Pantoja Yesica Meliza , Zambrano Guerrero Christian Alexander , Matabanchoy Tulcán Sonia Maritza , Narváez Chaves Armando David
Published: August 2021

El presente artículo tiene por objetivo analizar las concepciones sobre Calidad de Vida Laboral (CVL) en las organizaciones, a través de la revisión de distintas investigaciones encontradas en bases de datos especializadas durante los últimos 10 años. El estudio es una revisión sistemática (RS) descriptiva de literatura, siguiendo las directrices de la declaración PRISMA. En total se revisaron y analizaron 63 artículos de las bases de datos ScienceDirect, SciELO, Dialnet y Redalyc, que abordan las concepciones acerca de CVL en las organizaciones. Como conclusión, se menciona que la CVL se considera una categoría de análisis relativamente joven, que presenta variedad de definiciones operativas, que resultan por sí solas insuficientes para articular modelos teóricos bajo una única perspectiva; así, es necesario continuar con la investigación sobre CVL, para ampliar y fundamentar a través del estudio empírico una comprensión más clara, dado que esta categoría puede propender a la humanización de los puestos de trabajo y a mejorar la dignidad de los colaboradores.

Authors: Bonilla Algovia Enrique , Rivas Rivero Esther
Published: August 2021

El objetivo de este estudio ha sido conocer las creencias sobre el amor y sobre las relaciones íntimas que tiene un grupo jóvenes de la Comunidad de Madrid, así como explorar la posible relación entre estas creencias y la desigualdad de género en el ámbito de la pareja. La investigación se ha basado en un enfoque metodológico cualitativo y la información se ha recogido mediante la técnica de grupos focales. Participaron 34 estudiantes de la Universidad de Alcalá, con edades comprendidas entre los 18 y los 34 años (M = 21.32; DT = 3.12). Los resultados muestran que las creencias que tienen los hombres y las mujeres son distintas y parecen estar relacionadas con los mandatos de género tradicionales. La visibilización del imaginario sobre el amor en la juventud puede favorecer la puesta en marcha de programas preventivos que confronten las creencias desigualitarias y fomenten modelos relacionales basados en la igualdad, el respeto y la no violencia.
​Demonstration of Ecological Engineering based Pest Management in Rice Oryza sativa L. through Farmers Participatory Approach
Authors: Shanmugam P.S. , Sangeetha M. , Ayyadurai P. , Prasad Y.G.
Published: August 2021

Background: Rice is one of the predominant cereal crop grown in Dharmapuri district of Tamil Nadu state, India in approximately 4000 hectares with a average productivity of 4500 kg/ha. Hoppers, stem borer, leaf folder, gall midge and ear head bugs are the major insect pests for which farmers resort management practices. Instead of curative management, farmers mostly use the insecticide as prophylactic management which leads to unwarranted problems. Though integrated pest management has been advocated as an alternate strategy, farmers are reluctant to use all the components of IPM and rely on mostly on insecticides. In this context, the ecological engineering pest management can form a better alternative, which also coincides with the age old practice of growing border crops in this region. Methods: The potential of Ecological Engineering Pest Management (EEPM) was assessed in comparison with Integrated Pest Management (IPM) and Farmers Practice (FP) in five farmer’s fields. Based on the results, ten and twenty front line demonstrations were conducted during consecutive years to study the performance of EEPM in Dharmapuri district. Result: The number of hopper/hill, per cent dead heart, per cent white ears in the EEPM was 10.65, 7.07 and 9.65 and in the IPM module 10.18, 8.40 and 11.55 and in the farmers practice 6.73, 10.73 and 12.75 respectively. The natural enemies viz., coccinellids/hill and spiders/hill were more in EEPM (2.00 and 3.15) and least in the farmers practice (0.40 and 0.86). The number of hoppers/hill, per cent dead heart, number of coccinellids/hill and number of spiders per hill was 8.40, 6.00, 3.00 and 1.40 in EEPM and 6.20, 5.40, 1.20 and 0.60 in farmers practice respectively in the 2016-17 front line demonstrations. The EEPM module recorded 8.1, 8.65, 3.5 and 1.75 hopper/hill, per cent dead heart, coccinellids/hill and spiders/hill in 2017-18 front line demonstrations. The farmers were able to save Rs. 5000/- from the plant protection cost apart from getting additional revenue in EEPM. The combination of border crops, influence of border crop on rodent damage in rice ecosystem and benefits of providing separate niche area than border crop are the researchable areas. In spite of above constraints the EEPM can be followed in rice ecosystem with the locally available crop combination to reduce the insecticide usage and increase the beneficials.

Published: August 2021

Background: High variation in meat quality has been reported between animals and within muscles of same animals. An understanding of these variations is a pivotal step to design strategies for better utilization of such meat while producing high quality meat to consumers. The current study was aimed to unravel biochemical and physico-chemical profile of sheep hind limb. Methods: The sheep hind limb was procured from traditionally slaughtered sheep immediately after exsanguination. The Vastus lateralis (VL), Gluteo biceps femoris (GBF), Gluteomedius (GM), Longissimus thoracis et lumborum (LTL), Psoas major (PM) and Semitendinosus (ST) muscles were separated from hot boned carcass of sheep. Each hot boned muscle was cut and analysed for biochemical and physico-chemical characteristics. Result: There was significant (p less than 0.05) variation in water holding capacity, protein extractability (Sarcoplasmic, myofibrillar and total), collagen content, collagen solubility and instrumental colour value among different skeletal muscles studied. Non-significant (p greater than 0.05) variations were found in parameters like pH, drip loss, myofibrillar fragmentation index, muscle fibre diameter and Warner Bratzler shear force values. The Gluteo biceps femoris muscle was found to have higher myoglobin; myofibrillar fragmentation index and Warner Bratzler shear force values with lowest protein extractability values. The collagen content in the Gluteo biceps femoris was significantly (p less than 0.05) higher with lowest collagen solubility (15.32%) as compared to other muscles.

Authors: Sarkar Shatabhisa
Published: August 2021

Background: Non-conventional sources of starch like sweet potato, jackfruit seeds, dioscorea are under-utilized as compared to conventional sources. So, it is necessary to utilize these underutilized crops for enhancing their application in food. Custard powder prepared from modified starches (heat moisture treatment and hydroxypropylation crosslinking) were evaluated in the present study. Methods: Custard powder was prepared from native and modified (heat moisture treatment and hydroxypropylation crosslinking) starches of sweet potato, jackfruit seeds and dioscorea. The properties of custard powder and custard were analyzed for hygroscopicity, bulk density, total soluble solids, textual, viscosity, colour and sensory parameters. Result: Bulk density was higher for custard powder prepared from hydroxypropylated crosslinked starch. Viscosity and textural properties of custard prepared from hydroxypropylated crosslinked starch were good. On sensory score custard with hydroxypropylated crosslinked sweet potato starch was preferred by consumers.

Authors: Devi Indu , Dudi Kuldeep , Sinha Ranjana , Vikram R.
Published: August 2021

Background: Bio-acoustic features of animal’s voice can provide meaningful information about their biological and physical characteristics. The present study was conducted to get indicators of age from voice analysis and explore the relationship between voice features and seminal parameters in Sahiwal bulls. Methods: Voice samples were collected from healthy bulls (n=20), maintained at ICAR-NDRI, Karnal. Bulls were classified into two groups i.e. young bulls and adult bulls. The voice signals were analyzed by Adobe Premium software and acoustic features were extracted by using PRAAT software. Result: The mean of acoustic features viz. call duration (sec), mean intensity (dB), total energy (P2S), amplitude (P), pitch (Hz), unvoiced frame (%), jitter (%), bandwidth (Hz) mean N/H ratio (%) have been found significantly different while mean H/N ratio (dB), shimmer (%) and pulses were not found statistically (P greater than 0.05) different between adult and young bulls. The seminal parameters viz mass activity (0-5 scale), individual progressive motility (%), live sperm count (%) and total sperm abnormality (%) were found significantly different between adult and young bulls. No significant association between voice features and semen quality of bulls was observed. Hence, voice signals of male might provide some clues about their age but for semen quality, there is further need to explore the interesting relationship between voice features and fertility of breeding bulls.
Adaptation Strategies: Aesthetics of the Linguistic Codes Used by Drug Addicts in Portugal
Authors: Vicente José , Magalhaes Fernando
Published: August 2021

Daily continuous drug use becomes a chronic disease, and this causes the person to lose control over his actions and over his own life. The most used nomenclatures/terminologies when referring to drug users is “addict”. The desire to use drugs overrides all the activities and responsibilities that the drug addict must carry out in his daily life. The physical and psychosocial destruction of the drug user is quick and visible to all those around him and who lives with him daily. In Portugal, drug addicts, despite knowing that they are not criminalized for drug use, know and feel that this is not a socially accepted practice. In this sense, one of the ways that these people defend themselves from social criticism or judgment is through the elaboration of the perceptible linguistic signs and codes, which is understandable only by the drug addicts. In this research, the analysis dimension consisted of understanding and decoding these linguistic codes and to perceive the main reasons that are inherent to their use by drug addicts. According to the reports of drug addicts, it was possible to decode these linguistic codes of drug addicts and translate them into a language that can be accessible to the Portuguese society in general, and for all those who develop their professional practices with drug addicts. To carry out this research, the qualitative methodology was used, which is centered on a case study. Semi-structured interviews were used as a data collection technique. For data analysis, the content analysis was utilized.
Attitudes to Water Usage in Jordan
Authors: Bolton Laura
Published: August 2021

The author undertakes a literature review of attitudes to water usage in Jordan. One survey was identified which assessed attitudes towards water conservation, sampling 2000 residents in three regions in Jordan (Irbid, Amman, and Zarqa) in 2017. According to the survey, only 61% of respondents believed there was a water shortage in Jordan. 23% believed the water shortage was due to population pressures. The survey focussed more on water conservation than water use. Most of the respondents felt the government were not doing enough on water shortage issues. They were not asked how they feel about the role of the government versus their individual responsibility. Older respondents perceived the shortages to be more critical. A lack of interest in participating in water saving activities was identified among the youth. Water quality was perceived as poor in the USAID survey and noted in other sources. The survey found that most residents had management strategies in place for the day that the water was delivered. Views about politics of regional cooperation and refugee pressure on water use potentially affect attitudes to water but this was not identified specifically within the scope of this report.

The carpological collection of Professor Ivo Horvat, a famous Croatian botanist of 20th century, was saved from oblivion, after its unexpected discovery at the Faculty of Veterinary Medicine in Zagreb in 2019. As many as 515 diaspores (fruits and seeds) of 486 vascular plant taxa were systematised and digitised and the nomenclature was updated. A comprehensive comparison of Horvat’s carpological and herbarium collection (ZAHO) revealed a large amount of overlap. A large photo-catalogue was created and will be publicly accessible through the Flora Croatica Database.

Model pembelajaran yang digunakan di sekolah adalah model pembelajaran guided discovery namun hasil belajar yang diperoleh peserta didik masih rendah. Tujuan penelitian untuk mendeskripsikan ada atau tidaknya perbedaan hasil belajar yang signifikan menggunakan model pembelajaran guided inquiry dan guided discovery di kelas XI MIPA SMAN 6 Banjarmasin. Penelitian ini merupakan penelitian eksperimental dengan desain penelitian randomized pretest-posttest design. Pengambilan sampel menggunakan teknik cluster random sampling. Sebelum sampel diambil terlebih dahulu melakukan pengujian normalitas dan homogenitas pada hasil ulangan harian. Berdasarkan teknik tersebut diperoleh sampel, yaitu kelas XI MIPA 1 sebagai kelas kontrol dan XI MIPA 2 sebagai kelas eksperimen. Data penelitian diperoleh dari tes hasil belajar dalam bentuk soal uraian, yaitu pretest dan posttest. Data dianalisis menggunakan uji independent sample t-test. Nilai rata-rata posttest yang diperoleh kelas eksperimen lebih tinggi dibandingkan nilai rata-rata kelas kontrol. Hasil uji statistik menunjukkan bahwa nilai signifikansi yang lebih kecil dari pada taraf signifikansi a = 0,05. Hal ini menunjukkan bahwa terdapat perbedaan hasil belajar yang signifikan menggunakan model pembelajaran guided inquiry dan guided discovery di kelas XI MIPA SMAN 6 Banjarmasin. Dengan demikian model guided inquiry dapat direkomendasikan untuk digunakan sebagai alternatif untuk meningkatkan hasil belajar siswa. This research based on the low student learning outcomes seen from the results of daily tests. The study aims to determine whether or not there are significant differences in learning outcomes using the guided inquiry learning model and guided discovery in the XI MIPA class of SMAN 6 Banjarmasin. This research is experimental research with a randomized pretest-posttest design research design. The sample was taken by using the random cluster sampling technique. Before the samples were taken, they first tested the normality and homogeneity of the daily test results. Based on this technique, samples were obtained, namely class XI MIPA 1 as the control class and XI MIPA 2 as the experimental class. The research data were obtained from learning outcomes tests in description questions, namely pretest and posttest. Data were analyzed using an independent sample t-test. The average value of the posttest obtained by the experimental class is higher than the average value of the control class. Statistical test results show that the significance value is smaller than the significance level = 0.05. This shows significant differences in learning outcomes using guided inquiry and guided discovery learning models in class XI MIPA SMAN 6 Banjarmasin. Thus the guided inquiry model can be recommended to be used as an alternative to improve student learning outcomes.

Pyrethroid resistance is widespread in malaria vectors. However, differential mortality in discriminating dose assays to different pyrethroids is often observed in wild populations. When this occurs, it is unclear if this differential mortality should be interpreted as an indication of differential levels of susceptibility within the pyrethroid class, and if so, if countries should consider selecting one specific pyrethroid for programmatic use over another. A review of evidence from molecular studies, resistance testing with laboratory colonies and wild populations, and mosquito behavioural assays was conducted to answer these questions. Evidence suggests that in areas where pyrethroid resistance exists, different results in insecticide susceptibility assays with specific pyrethroids currently in common use (deltamethrin, permethrin, α-cypermethrin and λ-cyhalothrin) are not necessarily indicative of an operationally relevant difference in potential performance. Consequently, it is not advisable to use rotation between these pyrethroids as an insecticide resistance management strategy. Less commonly used pyrethroids (bifenthrin and etofenprox) may have sufficiently different modes of action, though further work would be needed to examine how this may apply to insecticide resistance management.
Understanding the Nature of the Long–Range Memory Phenomenon in Socio–Economic Systems

Published: August 2021

In the face of the upcoming 30th anniversary of econophysics, we review our contributions and other related works on the modeling of the long–range memory phenomenon in physical, economic, and other social complex systems. Our group has shown that the long–range memory phenomenon can be reproduced using various Markov processes, such as point processes, stochastic differential equations and agent–based models. Reproduced well enough to match other statistical properties of the financial markets, such as return and trading activity distributions and first–passage time distributions. Research has lead us to question whether the observed long–range memory is a result of actual long–range memory process or just a consequence of non–linearity of Markov processes. As our most recent result we discuss the long–range memory of the order flow data in the financial markets and other social systems from the perspective of the fractional Lèvy stable motion. We test widely used long-range memory estimators on discrete fractional Lèvy stable motion represented by the ARFIMA sample series. Our newly obtained results seem indicate that new estimators of self–similarity and long–range memory for analyzing systems with non–Gaussian distributions have to be developed.
WikiServe: Using Wikipedia to Match IoT based Services for Situation Response
Authors: Khan Sazid Zaman , Colman Alan , Sarker Iqbal H.
Published: August 2021

A large number of smart devices (things) are being deployed with the swift development of Inter- net of Things (IOT). These devices, owned by different organizations, have a wide variety of services to offer over the web. During a natural disaster or emergency (i.e., a situation), for example, relevant IOT services can be found and put to use. However, appropriate service matching methods are required to find the relevant services. Organizations that manage situation responses and organizations that provide IOT services are likely to be independent of each other, and therefore it is difficult for them to adopt a common ontological model to facilitate the service matching. Moreover, there exists a large conceptual gap between the domain of discourse for situations and the domain of discourse for services, which cannot be adequately bridged by existing techniques. In this paper, we address these issues and propose a new method, WikiServe, to identify IOT services that are functionally relevant to a given situation. Using concepts (terms) from situation and service descriptions, WikiServe employs Wikipedia as a knowledge source to bridge the conceptual gap between situation and service descriptions and match functionally relevant IOT services for a situation. It uses situation terms to retrieve situation related articles from Wikipedia. Then it creates a ranked list of services for the situation using the weighted occurrences of service terms in weighted situation articles. WikiServe performs better than a commonly used baseline method in terms of Precision, Recall and F measure for service matching.
Role of Lactic Acid Bacteria from Animal Products in Human Health – One Health Perspective
Authors: Miranda Carla , Contente Diogo , Igrejas Gilberto , Câmara Sandra Paula de Aguiar e , Dapkevicius Maria de Lurdes Enes , Poeta Patrícia
Published: August 2021

Animal products, in particular dairy and fermented products, are natural, major sources of lactic acid bacteria (LAB). Due to their antimicrobial properties, LAB are used in humans and in animals, with beneficial effects, as probiotics or in the treatment of a variety of diseases. In livestock production, LAB contribute to animal performance, health, and productivity. In the food industry, LAB are applied as bioprotective and biopreservation agents, contributing to improve food safety and quality. However, some studies have described resistance to relevant antibiotics in LAB, with the concomitant risks associated to the transfer of antibiotic resistance genes to foodborne pathogens, their potential dissemination throughout the food chain, and the environment. Here, we summarize the application of LAB in livestock and animal products, as well as the health impact of LAB in animal food products. In general, the beneficial effects of LAB on the human food chain seem to outweigh the potential risks associated with their consumption as part of animal and human diets. However, further studies and continuous monitorization efforts are needed to ensure their safe application in animal products and in the control of pathogenic microorganisms, preventing the possible risks associated with antibiotic resistance and, thus, protecting public health.
Detection of Influential Observations in Spatial Regression Model Based on Outliers and Bad Leverage Classification
Authors: Baba Ali Mohammed , Midi Habshah , Adam Mohd Bakri , Abd Rahman Nur Haizum Bint
Published: August 2021

Influential Observations, which are outliers in x direction, y direction or both, remain a hitch in classical regression model fitting. Spatial regression model, with peculiar nature of outliers due to their local nature, is not free from the effect of such influential observations. Researchers have adapted some classical regression techniques to the spatial models and yielded satisfactory results. However, masking or/and swamping remain stumbling block to such methods. We obtained the spatial representation of the classical regression measures of diagnostic in general spatial model. Commonly used diagnostic measure in spatial diagnostic, the Cook's distance, is compared to some robust methods, Hi2 (using robust and non-robust measures), and classification based on generalized residuals and diagnostic generalized potentials, ISRs-Posi and ESRs-Posi, with the help of the obtained spatial prediction residuals and the spatial leverage term. Results of simulation and applications to real data have shown the advantage of the ISRs-Posi and ESRs-Posi due to classification of outliers over Cook's distance and non-robust Hsi12, which suffer from masking, and robust Hsi22 which suffer from swamping in general spatial model.

Published: August 2021

Diabetic nephropathy (DN) has a steadily increasing prevalence, particularly because of the increase in sedentary lifestyle and obesity. It is defined as the persistent presence of albuminuria in a diabetic patient and requires early management to prevent progression to end-stage renal failure. The purpose of this work is to describe the epidemiologic profile and the progression of DN for the first time in a southern Moroccan region: Guelmim Oued noun - Moroccan Sahara.Patients and methods: It is a retrospective study conducted at the 5th military hospital in Guelmim and including all diabetic patients seen in nephrology consultation between January 2015 and December 2018. We collected the following parameters of our patients: demographics, comorbidities, prescribed treatments and biological data (Albuminuria, renal function and glycated hemoglobin) during their nephrology follow-up.Résults: During the study period 267 diabetic patients were included among 1042 patients, which represented 25.9% of the nephrology consultation activity. Their average age was 64.3 years with a slight male predominance (60%) and only two patients had type 1 diabetes. At the first nephrology consultation the average duration of diabetes was 14.6 years, 61 (22.8%) patients were on diet alone, 95 (35.5%) on oral antidiabetic drugs (OADs), 94 (35.2%) on insulin and 35 (13%) on OAD and insulin. Half the patients were hypertensive and 107 (40%) already had a cardiovascular complication (arterial disease, coronary artery disease or stroke). The average initial albuminuria was 388 mg/24h and the average glomerular filtration rate (GFR) was 67 ml/min ; 115 (43%) patients being in renal failure. 46 (17%) patients had no renal function assessment during their previous follow-up and only 139 (52%) were on renin-angiotensin system inhibitors (RASIs). After 12-month-follow-up in nephrology, the average GFR was 70 ml/min and 64 ml /min after two years.Conclusion: Diabetic nephropathy accounts for at least a quarter of nephrology consultation activity in the region of Guelmim Oued Noun. It is characterized in this context by the delay in treatment using renin angiotensin system inhibitors and late nephrology referral hence the need to strengthen preventive strategies in this region especially continuous training.
Dimethylsulfoniopropionate and dimethylsulfoxide in Posidonia oceanica
Authors: Richir Jonathan , Champenois Willy , de Fouw Jimmy , Borges Alberto V.
Published: August 2021

The present work aims at determining the natural variability of dimethylsulfoniopropionate (DMSP) and dimethylsulfoxide (DMSO) contents in the seagrass Posidonia oceanica, which is the largest producer of these molecules reported to data among coastal autotrophs. Samples were collected during a period of 3.5 years in the pristine Revellata Bay (Calvi, northwestern Corsica, France). The DMSP content ranged from 25 to 265 µmol.gfw−1; DMSO from 1.0 to 13.9 µmol.gfw−1. The dynamics of the two molecules were closely linked, the DMSO content being equivalent to 3.5 % of the DMSP content, all leaf samples considered (n = 423 samples and 414 DMSP(O) data pairs). The annual growth cycle of the seagrass diluted the initial stocks of the two molecules. Temperature indirectly affected molecule content dynamics through their direct effect on the seagrass productivity and biomass. Inter-annual variations in DMSP(O) content in relation to shallow water temperature might further indicate that DMSP(O) could have been involved in the physiological response of P. oceanica to heat-stress. Finally, middle-aged leaf tissues with an organosulfur molecule content similar to the average value calculated for the seagrass leaf bundle appeared to be the best choice of sample material to study DMSP and DMSO in that species. More research is needed to elucidate the biosynthetic pathways of these molecules in seagrasses, the evolutionary reasons for such a high production in P. oceanica and the physiological functions they play.

Cystic fibrosis (CF), due to variants in CFTR gene, is associated with chronic infection/inflammation responsible for airway epithelium alteration and lung function decline. Modifier genes induce phenotype variability between people with CF (pwCF) carrying the same CFTR variants. Among these, the gene encoding for the amino acid transporter SLC6A14 has been associated with lung disease severity and age of primary airway infection by the bacteria Pseudomonas aeruginosa. In this study, we investigated whether the single nucleotide polymorphism (SNP) rs3788766, located within SLC6A14 promoter, is associated with lung disease severity in a large French cohort of pwCF. We also studied the consequences of this SNP on SLC6A14 promoter activity using a luciferase reporter and the role of SLC6A14 in mammalian target of rapamycin (mTOR) signaling pathway and airway epithelial repair. We confirm that SLC6A14 SNP rs3788766 is associated with lung disease severity in pwCF (p=0.020; n=3,257, pancreatic insufficient, aged 6 to 40 years old), with the minor allele G being deleterious. In bronchial epithelial cell lines deficient for CFTR, SLC6A14 promoter activity is reduced in the presence of the rs3788766 G allele. SLC6A14 inhibition with a specific pharmacological blocker reduced 3H-arginine transport, mTOR phosphorylation and bronchial epithelial repair rates in wound healing assays.

Hirschsprung’s disease (HSCR) and its allied disorders are congenital entero-neuropathies with life-long implications in many cases. Here we report the effects of intravenous transplantation of cultured dental pulp stem cells derived from deciduous teeth (dDPSCs) into ‘Japanese fancy-1’ (JF1) mice with entero-neuropathy caused by Ednrb mutation. Intravenously injected dDPSCs (multipotent neural crest cells with low immunogenicity) migrated to affected regions of the intestine through interactions between stromal cell-derived factor-1α and C-X-C chemokine receptor type-4. Notably, transplanted dDPSCs differentiated into both enteric neurons and pacemaker interstitial cells to correct abnormalities in the electrical and mechanical activities of the proximal colon. dDPSC transplantation also led to repair of the small intestinal mucosa, changes in the gastrointestinal microbiota, improvements in nutritional status and prolongation of survival. We anticipate that dDPSC transplantation could be developed into a novel cell-based therapy for HSCR and its allied disorders.

Rapid spatial evaluation of earthquake-hit population after earthquake occurrence is required in the disaster emergency rescue management, due to its significant support for decreasing casualties and property losses. The correlation between earthquake-hit population and influencing factors are analyzed using the data from the 2013 Ms7.0 Lushan earthquake. Ten influencing factors including elevation, slope angle, population density, per capita GDP, distance to fault, distance to river, NDVI, PGA, PGV and distance to epicenter, are classified into environmental factors and seismic factors. The correlation analysis reveals characteristics that there is a nonlinear relationship between the earthquake-hit population and various factors, and per capita GDP and PGA factor have a stronger correlation with earthquake-hit population. Moreover, the spatial variability of influencing factors would affect the distribution of earthquake-hit population. The earthquake-hit population is evaluated using BP neural network with optimizing training samples based on the spatial characteristics of per capita GDP and PGA factors. Different number of sample points are generated in areas with different value intervals of influencing factors, instead of the random distribution of sample points. The minimum value of RMSE (Root Mean Square Error) from testing set is 18 people/km2, showing good accuracy in the spatial evaluation of earthquake-hit population. Meanwhile, the optimizing samples considering spatial characteristics could improve the convergence speed and generalization capability comparing to random samples. The trained network was generalized to the 2017 Ms7.0 Jiuzhaigou earthquake to verify the prediction accuracy. The mean absolute error of earthquake-hit population evaluation results in different counties under the Jiuzhaigou earthquake were 18357 people and 26121 people for optimizing samples and random samples, respectively. The evaluation results indicate that BP neural network considering the correlation characteristics of factors has the capability to evaluate the earthquake-hit population in space, providing more detailed information for emergency service and rescue operation.

The impetus of the present study is to examine the effect of nonlinearity on the efficiency enhancement of a capacitive energy harvester. The model consists of a cantilever microbeam underneath which there is an electret layer with a surface voltage, which is responsible for the driving energy. The packaged device is exposed to unwanted harmonic mechanical excitation. The microbeam undergoes mechanical vibration and accordingly the energy is harvested throughout the output circuit. The dynamic formulation accounts for nonlinear curvature, inertia, and nonlinear electrostatic force. The efficiency of the device in the vicinity of the primary and super-harmonic resonances is examined and accordingly the output power is evaluated. Bifurcation analysis is carried out on the dynamics of the system by detecting the bifurcations in the frequency domain and diagnosing their types. One of the challenging issues in the design and analysis of energy harvesting devices is to broaden the bandwidth so that more frequencies are accommodated within the amplification region. In this study the effect of the nonlinearity on the bandwidth broadening, as well as efficiency improvement of the device, is studied.
Hybrid Flow Shop with Limited Transportation Scheduling Problem: A Comparison Between Genetics Algorithm, and a Novel Recursive Local Search Heuristic

Published: August 2021

In this paper, concurrent scheduling of jobs and transportation in a hybrid flow shop system is studied, where multiple jobs, transporters, and stages with parallel unrelated machines are considered. In addition to the mentioned technical features, jobs are able to omit one or more stages, and may not be executable by all the machines, and similarly, transportable by all the transporters. Unlike most studies in the literature, the transport resource is finite and needs to be simultaneously scheduled with the jobs. Initially, a new mixed integer linear programming (MILP) model is proposed to minimize the makespan. Then, a novel Recursive Local Search Heuristic (RLSH) is proposed to tackle the large-sized instances, which otherwise could not be solved via MILP solver (Gurobi) in reasonable time. RLSH is also compared against Genetics Algorithm (GA) on a set of numerical examples generated from the uniform distribution. As the computational results demonstrate, it is concluded that RLSH is extremely efficacious dealing with the problem and outperforms GA in the objective value quality. Finally, using two well-known statistical tests: Wald and analysis of variance(ANOVA), we assess the performance of the suggested approaches.

Oil-immersed transformers use paper and oil as insulation system which degrades slowly during the operation of these machines. The fast-developing electric power industry demands superior performance of electrical insulation materials which has led to the development of new materials whose measurement of the degree of polymerization has found some practical difficulties. Moreover, the increasing interest in synthetic dielectric materials replacing cellulose materials requires the use of alternative methods to the degree of polymerization to quantify the degradation of insulation solids over time. In this sense, this paper proposes the possibility of analyzing paper degradation through fracture toughness. An accelerated thermal ageing of Kraft paper in mineral oil was carried out at 130ºC during different periods of time, to obtain information on the kinetics of the ageing degradation of the paper. Double-edged notched specimens were tested in tension to study their fracture toughness. The evolution of the load-displacement curves obtained for different ageing times at the ageing temperature of 130°C was utilized to the determination of the stress intensity factor. Furthermore, different kinetic models based on this stress intensity factor were applied to relate its evolution over time as a function of the temperature. Finally, the correlation between the DP and stress intensity factor, which depends on the fiber angle, was also defined.

PurposeThis is the first study to systematically evaluate the diagnostic accuracy of intraoperative specimen radiography on margin level and its potential to reduce second surgeries in patients treated with neoadjuvant chemotherapy. MethodsThis retrospective study included 174 cases receiving breast conserving surgery (BCS) after neoadjuvant chemotherapy (NACT) of primary breast cancer. Conventional specimen radiography (CSR) was performed to assess potential margin infiltration of the target lesion and recommend an intraoperative re-excision of any radiologically positive margin. The histological workup of the specimen served as gold standard for the evaluation of the accuracy of CSR and the potential reduction of second surgeries by CSR-guided re-excisions. A subgroup analysis was performed for patients with and without clinical complete response. Results 1044 margins were assessed. Of 47 (4.5%) histopathological positive margins, CSR identified 9 correctly (true positive). 38 infiltrated margins were missed (false negative). This resulted in a sensitivity of 19.2%, a specificity of 89.2%, a PPV of 7.7% and a NPV of 95.9%. The rate of secondary procedures was reduced from 23 to 16 with a number needed to treat (NNT) of CSR guided intraoperative re-excisions of 25. In the subgroup of patients with cCR, the prevalence of positive margins was 10/510 (2.0%), PPV was 1.9% and the NNT was 85. ConclusionPositive margins after NACT are rare and CSR has only a low sensitivity to detect them. Thus, the rate of secondary surgeries cannot be significantly reduced by recommending targeted re-excisions, especially in cases with cCR.

The purpose of this study is to explore the relationship between PCAT1-SNPs and breast cancer (BC) susceptibility. Logistic regression analysis was applied to determine the association between PCAT1-SNPs and BC risk. The relative expression of PCAT1 in different genotypes was detected by qRT-PCR. The binding between the genotype of C/T at rs4473999 locus and miR-149-5p was confirmed by dual luciferase gene reporter assays. The proliferation, migration and invasion of BC cells with dysregulated expression of miR-149-5p was evaluated by CCK8, Scratch and Transwell assay, respectively. Logistic regression analysis revealed PCAT1-SNPs was related to the susceptibility of BC that rs117117537 (OR:2.413, 95%CI: 1.057–5.508) and rs4473999 (OR:2.137 95%CI: 1.065–4.286) were risk factors of BC when the menopausal age was ≥ 50; The haplotype Grs1551514Trs1551513Crs4473999Crs9656964Trs17762938Crs7823297Trs785003Trs117117537 may increase the risk of BC (OR:1.614 95%CI: 1.116–2.333), and there was an association between genes and reproductive factors (OR:2.487 95%CI: 1.929–3.206). Preliminary functional studies demonstrated that PCAT1 interacted with miR-149-5p when rs4473999 carried wild type C; In addition, the dysregulated enrichment of miR-149-5p may affect the proliferation, invasion and migration of BC cells. Our study shows that PCAT1 gene polymorphism is related to BC susceptibility, PCAT1-rs4473999 C/T genotype may affect the occurence of BC by modulating the interactions with miR-149-5p.
