An optimization-based planning tool for on-demand mobility service operations

Abstract Regions worldwide are adopting and exploring low-speed automated electric shuttle (AES) service as an on-demand shared mobility service in dense geofenced urban areas. Building on this concept, the National Renewable Energy Laboratory (NREL) recently developed the Automated Mobility District (AMD) toolkit. The AMD toolkit—comprising of a travel micro-simulation model and an energy estimation model—estimates the mobility and energy impacts of a given shuttle configuration within an AMD. Early-stage AMD deployments need to find optimal operational configurations that include: (a) passenger capacity of an AES, (b) time-dependent routes, and (c) fleet size (AES units) to satisfy the demand for the region. This research extends the AMD toolkit functionality by developing an optimization-based planning module that will assist in the operations of AES units. We developed a constrained mixed-integer program accounting for passenger waiting time, battery range, and passenger capacity of AES units. For scalability, we demonstrated the Tabu search-based solution technique for a real-world network—a proposed AMD deployment in Greenville, South Carolina, USA. Compared to rule-based operations, our developed solution yields higher travel time and energy savings for the network at different demand levels. The sensitivity analyses for waiting time thresholds indicate nonlinearity in the system performance, underscoring the need to meet shared-use mobility user-level expectations. The developed optimization framework can be adapted and extended to accommodate different categories of shared-use on-demand mobility services.
Influence of Phenethyl Acetate and Naphthalene Addition before and after Pyrolysis on the Quantitative Analysis of Bio-Oil

The condensation-collection and quantitative analysis of bio-oil limit its component investigation and utilization. In order to find a convenient method for the analysis of bio-oil, the present study conducted an attempt for bio-oil quantitative analysis with the addition of internal standards before pyrolysis. Based on their good thermal stability, phenethyl acetate and naphthalene were selected as standards in the study and experiments were carried out to compare the effects of two added modes (adding into the biowaste before pyrolysis or adding into bio-oil after pyrolysis) on the bio-oil analysis. The results showed that both phenethyl acetate and naphthalene were mainly volatilized under testing conditions, which could be transferred into the oil with the volatile matters during biowaste pyrolysis. Through the co-pyrolysis experiments of the internal standards with lignin and cellulose, almost no interactions were found between the internal standards and such components. Furthermore, adding these standards before pyrolysis hardly affected the properties of noncondensable gas and biochar from the used biowaste samples (tobacco and sawdust waste). Compared with the bio-oil analysis results via traditional methods by adding standards into the bio-oil after pyrolysis, the results regarding the component distribution characteristics of the bio-oil were similar using the proposed method through the addition of standards before pyrolysis. Considering adequate mixing of the added standards (before pyrolysis) in the generated bio-oil, the proposed method could partly help to avoid inaccurate analysis of bio-oil components caused by incomplete collection of the pyrolytic volatiles.

STUDY ON MAGNETIZATION TREATMENT AND CUTTING PERFORMANCE OF A NEW-TYPE OF TRIETHANOLAMINE BORATE CUTTING FLUID

The composition of water-based cutting fluid and emulsion is different, and it has not been reported whether the magnetization treatment will affect the performance of water-based cutting fluid. In this study, a newly developed triethanolamine borate water-based cutting fluid is used as the research object to study the magnetization treatment technology and the law of its influence on cutting performance systematically. The cutting fluid magnetization experimental system was set up based on the principle of magnetization and the influence of magnetization parameters (magnetic field strength, magnetization duration) on the results of magnetization was further studied. The experimental results are measured by force measuring instrument, temperature measuring instrument, roughness measuring instrument and scanning electron microscope, and the parameters such as milling force, milling temperature, surface roughness, cutting specific energy, friction coefficient and workpiece surface morphology are comprehensively analyzed through data processing; the performance of cutting fluid before and after magnetization is also compared. The test results show that the magnetization effect is best when the magnetic field strength is 10000GS and the magnetization time is 40 minutes. The mechanism of magnetization treatment is to change the macromolecular group into a small molecular group, and the disordered array of molecules becomes ordered.
Enhancement of chlorine resistance in carbon nanotube-based nanocomposite reverse osmosis membranes

Aromatic polyamide membranes, which are prepared by interfacial polymerization of m-phenylene diamine (MPDA) in water solution and trimesoyl chloride (TMC) in organic solution, have been widely used as reverse osmosis (RO) membranes for desalination of seawater. However, it has been pointed out that polyamide RO membranes have weak resistance to chlorine, causing deteriorated separation performance. In this study, nanocomposite RO membranes containing multi-walled carbon nanotube (MWCNT) were developed to enhance the chlorine resistance of polyamide membranes. The resulting membranes were analyzed and tested to see the desalination performance. Nonionic surfactant (Triton-X-100) was used in the interfacial polymerization of organic/inorganic nanocomposite RO membranes to improve the dispersion of MWCNTs in the polymer matrix. Scanning electron microscopy (SEM) images and X-ray diffraction (XRD) spectra confirmed that MWCNTs were uniformly distributed in the polymer matrix. When 0.1–1 wt% of MWCNTs were ad.
The Effectiveness and Safety of Manual Acupuncture Therapy in Patients with Poststroke Cognitive Impairment: A Meta-analysis

Background. Poststroke cognitive impairment (PSCI) is a common cause of disability among patients with stroke. Meanwhile, acupuncture has increasingly been used to improve motor and cognitive function for stroke patients. The aim of the present study was to summarize and evaluate the evidence on the effectiveness of acupuncture in treating PSCI. Methods. Eight databases (PubMed, The Cochrane Library, CNKI, WanFang Data, VIP, CBM, Medline, Embase databases) were searched from January 2010 to January 2020. Meta-analyses were conducted for the eligible randomized controlled trials (RCTs). Assessments were performed using Mini-Mental State Examination (MMSE), Montreal Cognitive Assessment (MoCA), Barthel Index (BI), or modified Barthel Index (MBI). Results. A total of 657 relevant RCTs were identified, and 22 RCTs with 1856 patients were eventually included. Meta-analysis showed that acupuncture appeared to be effective for improving cognitive function as assessed by MMSE ( mean difference MD = 1.73 , 95% confidence interval (CI) (1.39, 2.06), P < 0.00001 ) and MoCA ( MD = 2.32 , 95% CI (1.92, 2.73), P < 0.00001 ). Furthermore, it also suggested that acupuncture could improve the activities of daily life (ADL) for PSCI patients as assessed by BI or MBI ( SMD = 0.97 , 95% CI (0.57, 1.38), P < 0.00001 ). Conclusions. Compared with nonacupuncture group, acupuncture group showed better effects in improving the scores of MMSE, MoCA, BI, and MBI. This meta-analysis provided positive evidence that acupuncture may be effective in improving cognitive function and activities of daily life for PSCI patients. Meanwhile, long retention time of acupuncture may improve cognitive function and activities of daily life, and twist technique may be an important factor that could influence cognitive function. However, further studies using large samples and a rigorous study design are needed to confirm the role of acupuncture in the treatment of PSCI.
Análise do Engajamento dos Alunos em Ambientes Virtuais de Aprendizagem para detecção de comunidade

There is an increasing number of courses taught using virtual learning environments. However, these environments face the challenge of keeping students motivated and engaged. A huge amount of data is generated by these environments that can be used to discover patterns regarding student engagement. In this work, a model based on undirected graphs was proposed, where the elements represent students and their connections are similarity in their behavior. The Label Propagation algorithm was used to group students based on three engagement metrics. A quantitative analysis was carried out to identify students who are not engaged who may need help. The results point to a significant difference concerning students’ actions that represent the phenomenon of engagement between students with better and worse performance. Resumo. Há um número crescente de cursos ministrados utilizando ambientes virtuais de aprendizagem. Contudo, esses ambientes enfrentam o desafio de manter alunos motivados e engajados. Uma grande quantidade de dados é gerada por esses ambientes e podem ser usados para análise de comportamento dos alunos. Neste trabalho, é proposto um modelo baseado em grafos não direcionados para identificar o engajamento de alunos. O algoritmo Label Propagation foi utilizado para agrupar os alunos com base em três métricas de engajamento. Uma análise quantitativa foi realizada para identificar os alunos não engajados que possam precisar de intervenção. Os resultados apontam para uma diferença significativa em relação às ações dos alunos que representam o fenômeno do engajamento entre os alunos de melhor e pior desempenho.
Identifying Priority Giant Anteater (Myrmecophaga tridactyla) Populations for Conservation in São Paulo State, Brazil

Abstract Habitat loss is the main threat to biodiversity conservation worldwide. Some species may be particularly susceptible to the effects of fragmentation and the isolation of populations. The impacts of human activity on wild animal populations may be understood through relationships between individual genetic data and spatial landscape variables, particularly when considering local population dynamics influenced by fragmented habitats. Thus, the objective of this study was to analyze the population structure and genetic diversity of the giant anteater (Myrmecophaga tridactyla) using an individual sampling scheme (ISS) on a regional geographic scale. Data were collected from 41 specimens from twenty different locations in São Paulo State, Brazil, and six polymorphic microsatellite loci were genotyped. Our results indicate that barriers to gene flow exist and have segregated individuals of the farther away areas into two spatially structured clusters. The populations were also found to have high genetic diversity. The experimental sampling approach used herein enabled an analysis of the population dynamics of the giant anteater on a regional scale, as well as the identification of priority populations for genetic resource conservation for this species. The results reflect the need for adequate management plans. The efficacy of the sampling scheme may vary based on the study model used, but we argue that the use of an ISS combined with suitable molecular markers and statistical methods may serve as an important tool for initial analyses of threatened or vulnerable species, particularly in anthropized regions where populations are small or hard to characterize.
Cardiac muscle activation; the role of length dependent activation and the novel myosin activator danicamtiv

B: Alterations in the length dependent activation (LDA) of left ventricular (LV) muscle fibres, the mechanistic driver of the Frank-Starling Law of the heart, are thought to mediate impaired LV function in heart failure (HF). However, little is known about LDA's role in the left atria (LA). Given the concomitant presence of LA dysfunction in HF, the purpose of this study was to compare/assess LDA on LA and LV muscle, as well to evaluate the effects of a novel small-molecule acto-myosin activator, danicamtiv (formerly known as MYK-491). M: LA and LV myofibrils from healthy Yucatan mini-pigs were used to determine biomechanical function with ATPase assays, with and without danicamtiv. Skinned LA and LV muscle fibres from these same animals were prepared to study contractile force, Ca2+ sensitivity, active/passive stiffness, and responsiveness to increasing sarcomere length (2.0 and 2.3). These parameters were also evaluated in the presence of danicamtiv. R: LA myofibrils had significantly faster ATPase and Pi release rates compared to LV, consistent with their respective alpha/beta myosin-isoform content. Despite increased metabolic rate, LA fibres generated less maximum isometric tension (12.3±1.96 vs 35.2±3.07 mN/mm2) and had a lower pCa50 than LV fibres (5.66±0.02 vs 5.82±0.02), demonstrating reduced force-generating capability and Ca2+ sensitivity. Stretch of LV fibres resulted in a gain in tension over a range of pCas (pCa6.4, 6.2, 6.0, and 5.8, all p<0.05). However, in LA, LDA-induced gain was not significant at submaximal pCas (pCa6.4, 6.2, 6.0, all p>0.05). Stretch had no effect on active stiffness, but increased passive stiffness in both muscle types. Stretched LA fibres showed grater passive stiffness compared to LV (196.7±21.5 vs. 138.5±22.3 kN/m3). A stiffer myofilament would in part explain the blunted ability of the LA to generate force in response to stretch. Danicamtiv activated both LA and LV myofibrils, increasing ATPase and Pi release rates, and increased Ca2+ sensitivity in fibres (ΔpCa; LV, 0.320±0.032; LA, 0.149±0.028, p<0.01). Unlike with stretch, danicamtiv had no effect on passive stiffness, yet altered the active stiffness/tension (S/T) relationship in both fiber types, but, differentially. In LV, danicamtiv increased the number of available heads (Y0; 129.9±26.3 vs 10.1±4.2 kN/m3, p<0.001) with no significant effect on slope. In the LA, Y0 was largely unchanged with a significant increase in the slope of the S/T relationship (slope: 34.0±2.9 vs. 20.0±1.9 au, p<0.01). Together, these data suggest an increased number of force producing cross-bridges, without altering passive stiffness. C: These data confirm the functional differences between LA and LV muscle fibres and demonstrate a blunted ability of LA tissue to recruit force when stretched. The acto-myosin activator danicamtiv increased biochemical activity, Ca2+ sensitivity, and the active S/T relationship in LA and LV fibres without altering passive strain.

The Role of Social Media Marketing Activities on Customer Equity Drivers and Customer Loyalty

During the past few years, adoption of e-commerce in Indonesia has been increasing along with other trends in information , communication and technology sector such as widespread use of smartphones and social media. To promote its services, e-commerce firms have also embraced social media and carry out social media marketing activities. This study is aimed to test the influence of social media marketing activities toward customer loyalty through customer equity drivers (i.e. Value Equity, Brand Equity, dan Relationship Equity.). A survey was conducted using convenience sampling technique to select respondents. A total of 161 usable responses were used in the main data analysis. This study found support for the five dimensions of social media marketing activities suggested from previous study. Furthermore, this study found that social media marketing activities affect value equity, brand equity and relationship equity. This study also found that two customer equity drivers (brand equity and relationship equity)had a positive effect on customer loyalty, while value equity had a positive effect on customer loyalty, but it was not significant. Discussion and managerial implications were also discussed in this study
The social dimension of barrier effects of transport infrastructure

Motorways and railways increase regional accessibility but can at the same time reduce local accessibility by creating barriers in pedestrian and bicycle networks. This can influence several SDGs, such as SDG 5 (gender equality), 10 (reduced inequalities), and 11 (sustainable cities and communities). This paper presents some first principles of how quantitative indicators of direct barrier effects can be adapted in order to address specific social groups. To demonstrate this, the indicator ‘Choice’, from a set of four indicators previously developed, was adapted to assess accessibility by children to parks, and waterside and leisure facilities. The indicator was applied to a case in Gothenburg, Sweden, where a GIS-based analysis measured changes in barrier effects brought about by hypothetically placing an existing motorway and railway in tunnels. The results demonstrate how such local accessibility indicators can be adapted to make them relevant for impact assessments of infrastructure projects, and thus enable the measurement of compliance with social sustainability targets in transportation infrastructure planning.
Hydroxypropylcellulose films as alignment layers for liquid crystals

Homogeneous surface alignment of liquid crystals (5CB) is observed for films formed by coating with aqueous solutions of hydroxypropylcellulose (HPC) for high coating speeds and thin coating thicknesses. On the other hand, for films formed with isotropic ethanol solutions of HPC, 5CB molecules retain the flow-induced alignment created at the formation of the 5CB droplet. The microstructures responsible for the homogeneous surface alignment are not confirmed in the morphological measurement of the film surface with an atomic force microscope, although large grooves corresponding to the banded texture perpendicular to the coating direction exist on the films formed with liquid crystalline solutions of HPC. The possibility of highly oriented HPC molecules in the coating flow is pointed out using the Doi model. These results suggest that the flow-induced anisotropic orientation of HPC molecules is responsible for the homogeneous surface alignment of 5CB.
Synthesis of Highly Branched Polyethylene Using “Sandwich” (8-p-Tolyl naphthyl α-diimine)nickel(II) Catalysts

Nickel(II) α-diimine dibromide complexes incorporating 8-p-tolylnaphthylimino groups have been prepared and used for ethylene polymerization by activation with modified methylalumoxane (MMAO). These catalysts possess increased axial bulk relative to standard diimine-nickel complexes, resulting in lower rates of chain transfer relative to chain propagation rates and thus higher polymer molecular weights and narrower PDIs. They yield the most highly branched PE produced by Ni catalysts seen to date. The easy synthesis of 8-aryl-1-naphthylamines provides ready access to a new class of α-diimine-based nickel catalysts in which the 8-substituent is ideally positioned to provide steric bulk at the axial sites.
Determinantes de las condiciones de empleo de los egresados de programas de doctorado del Padrón Nacional de Posgrados de Calidad en México. Una apuesta por las redes

This article will attempt to analyze public policies aimed to mental health in the argentine territory, fundamentally those related to the socio-community care modality and its implementation once it has been established as one of the main objectives of the National Mental Health Plan; in that matter, it will seek to highlight its main characteristics and devices throughout the 2014-2019 period, and then rethink from a critical perspective the main barriers and challenges in pursuit of its e ectiveness as a comprehensive public policy, with a human rights-oriented perspective of the citizens to whom it is addressed. Finally, it can be concluded that, despite the satisfactory experiences and signi cant progress in what is proposed by the National Mental Health Plan, community care in mental health as a comprehensive and national public policy is up to now a challenge and a pending objective but with possible alternatives to achieve it.
Determinants of Overall Knowledge and Health Behaviors Towards Hepatitis B and C Among Ever-Married Women in Pakistan: Evidence Based on Demographic and Health Survey 2017–18

Background: In 2019, around 5 million and 10 million people were affected by hepatitis B virus (HBV) and hepatitis C virus (HCV) respectively in Pakistan. On World Hepatitis Day 2019, Pakistan’s Government announced the Prime Minister’s Plan to eliminate HBV and HCV from the country by 2030. In order to achieve this goal, adequate knowledge about HBV and HCV regarding mode of transmission, symptoms of the disease, and awareness about available treatments and vaccines is imperative. The present study aims to investigate the determinants related to overall knowledge about and behaviour in relation to HBV and HCV amongst married women in Pakistan.Methods: Secondary data analysis was carried out using the Pakistan Demographic and Health Survey (PDHS) 2017–18. A series of questions regarding women’s knowledge about how to avoid HBV and HVC and their health behaviour in relation to HBV and HCV were posed to 12,364 ever-married women of reproductive age (15–49 years). Bivariate and multivariable logistic regression was applied to examine the effects of socio-demographic characteristics and covariates on women’s overall knowledge and health behaviour regarding HBV and HCV.Results: The findings highlight that the majority of women (88.3%) have heard of HBV and HCV. Nonetheless, only 34.8% had comprehensive knowledge about how to avoid HBV and HCV. Few women (11.3%) had been tested for HBV or HCV during the year preceding the survey. Furthermore, the results indicated that women from Sindh, living in urban areas, aged 35 years and over, having more than 10 years of schooling, belonging to the richest wealth quintile and working as professionals or in clerical/sales & service jobs reported better knowledge and health behaviours regarding HBV and HCV.Conclusion: This study provides evidence that women’s socio-demographic characteristics create differences in their overall knowledge about and attitudes towards HBV and HCV. This research emphasized that there is a need to create awareness about the causes and prevention of HBV and HCV in order to achieve the goal of eliminating these diseases in Pakistan by 2030.
