Mixed integer linear programming models for minimizing ergonomic risk dispersion in an assembly line at the Nissan Barcelona factory
Authors: Bautista-Valhondo Joaquín , Alfaro-Pozo Rocío
Published: July 2020

We present a variant of the approach to the assembly line balancing problems, with the aim of reducing the ergonomic risk for operators of mixed-model assembly lines (MILP-3). Specifically, the MILP-3 model is focused on minimizing the average range between ergonomic risk values of workstations. Using a case study from Nissan’s plant in Barcelona, not only are the differences between levels of ergonomic risk of stations reduced, but we attempt to reduce the average maximum ergonomic risk of the assembly line. The new model is compared with two others, MILP-1 and MILP-2, which minimize the average maximum ergonomic risk and the average absolute deviation of the risks, respectively.

Published: July 2020

Tradicionalmente, en la aproximación formal a la secuenciación de producción denominada en inglés Theory of Scheduling (o simplemente scheduling), se suele obviar la limitación de capacidad entre los diferentes recursos de cara a establecer el programa de producción. Sin embargo, el paradigma Lean Manufacturing ha dejado patente que la limitación de capacidad física en los sistemas productivos es una característica que influye en los resultados de los programas de producción, por lo que las configuraciones empezando a ser objeto de estudio en la dirección de operaciones. En este artículo se hace una revisión de las principales características de la secuenciación con almacenes limitados que se han abordado bajo la teoría de secuenciación y se resumen las referencias más importantes publicadas durante los últimos años. Finalmente, se presentan una serie de conclusiones con el objetivo de clarificar algunas líneas de interés para los investigadores del tema.

Respiratory failure: Classification, Epidemiology and Etiology Review
Authors: Ernest Vergel
Published: July 2020

Respiratory failure is a detailed syndrome of the respiratory system failing to perform the function of gas exchange, oxygen intake, and carbon dioxide release. Acute respiratory failure is the most common cause of organ failure in intensive care units (ICUs) with high mortality rates. The classification can be reviewed from two categories of acute respiratory failure and chronic respiratory failure. Acute respiratory failure is often found with the failure of other vital organs. Death is caused by multiple organ dysfunction syndrome (MODS). Etiology can be seen in two categories, namely Central nervous system Depression, Impaired ventilation, Impaired equilibrium perfusion ventilation (V/Q Mismatch), Trauma, Pleural effusion, hemothorax, and pneumothorax, Acute pulmonary disease. Respiratory failure, like failure in other organ systems, can be identified based on clinical features or laboratory tests.

Interpretation Approaches For Biblical Apocalyptic Literature: An Evaluation
Authors: Asamoah Emmanuel Forster
Published: July 2020

Apocalyptic literature is one of the literature that has been subjected to numerous exegetical approaches due to the difficulty of understanding its content. This has resulted in misinterpretation among Christians. After discussing the available models for apocalyptic literature in this study, it was understood that the eclectic approach remains a preferable alternative for interpreting apocalyptic literature. Its steps must be utilized as a whole to yield intended results for a sound interpretation of apocalyptic literature for both the Old Testament and the New Testament.

Keywords: Apocalyptic literature, Preteristt Approach, Idealist Approach, Futuristic Approach, Historicist Approach, Propheticist Approach, Eclectic Approach, Revelation.
A Theological Analysis of Issues Arising from the Christian Asante Chief’s Relationship with the Black Stool (Akonwa Tuntum)
Authors: Ofori Samuel
Published: July 2020

One of several issues of contention that have created a gulf between Christianity and the traditional Asante chieftaincy institution is the chief’s relationship with the black stool. The general perception of Christians is that the black stool is an object of worship, it is demonic and should be avoided by Christian chiefs. This paper theologically analyzes the issues of contention in the Christian chief’s relationship with the black stool and presents a Christian response to guide them. This is an empirical qualitative study, and it uses a phenomenological approach to understand the phenomena related to the issues of contention in the Christianity-chieftaincy encounter. The method of obtaining information included interviews of fifty (50) Christian Asante chiefs, a representative group obtained by the purposeful sampling method. Information was also obtained through personal observation of some of the traditional religious rituals they perform. The issues of contention were then examined in the light of scripture in order to help bridge the seeming gulf between Asante chieftaincy and Christianity. This research has established the fact that the black stool is not a demonic object. In fact, the issues of contention in the Christianity and chieftaincy encounter, relating to the black stool, have arisen not only from a lack of understanding and proper appreciation of the traditional rituals but also from lack of proper understanding and poor interpretation of scriptural texts used in relating the gospel to the chieftaincy institution.

Keywords: Tradition, ritual, Christianity, Black stool (Akonwa Tuntum), worship.
The Theology and Classification of the Asomdwee Ntonton Nkabom Som
Authors: Adam Iddrissu Shaibu
Published: July 2020

This paper explores the theology and classificatory model of the Asomdwee Ntonton Nkabom Som. The classificatory model of New Religious Movements that this movement belongs to is unknown and not much has been written regarding its theology as well. Both primary and secondary sources were consulted. The complex and diverse nature as well as variety of taxonomies of New Religious Movements has partially contributed to the lack of consensus regarding having a precise definition. Based on existing classificatory model, this faith was classified as a Hebrais messianic movement. The movement has its unique and distinct theology, which to some extent, is similar to that of Christianity and Islam and this makes the movement to be seen outwardly as an amalgamation of Christianity and Islam. As such, a thorough research regarding the theology and cultural dimension of the faith is significant for Christian scholarship.

Observational Quantification of Three-dimensional Anisotropies and Scalings of Space Plasma Turbulence at Kinetic Scales
Authors: Wang Tieyan , He Jiansen , Alexandrova Olga , Dunlop Malcolm , Perrone Denise
Published: July 2020

A statistical survey of spectral anisotropy of space plasma turbulence is performed using five years of measurements from the Magnetospheric Multiscale mission in the magnetosheath. By measuring the five-point second-order structure functions of the magnetic field, we have for the first time quantified the three-dimensional anisotropies and scalings at sub-ion scales (<100 km). In the local reference frame

defined with respect to local mean magnetic field

Effects of Thermal Emission on the Transmission Spectra of Hot Jupiters
Authors: Chakrabarty Aritra , Sengupta Sujan
Published: July 2020

The atmosphere on the dayside of a highly irradiated close-in gas giant (also known as a hot Jupiter) absorbs a significant part of the incident stellar radiation, which again gets re-emitted in the infrared wavelengths both from the day and the night sides of the planet. The re-emitted thermal radiation from the nightside facing the observers during the transit event of such a planet contributes to the transmitted stellar radiation. We demonstrate that the transit spectra at the infrared region get altered significantly when such re-emitted thermal radiation of the planet is included. We assess the effects of the thermal emission of the hot Jupiters on the transit spectra by simulating observational spectroscopic data with corresponding errors from the different channels of the upcoming James Webb Space Telescope. We find that the effect is statistically significant with respect to the noise levels of those simulated data. Hence, we convey the important message that the planetary thermal re-emission must be taken into consideration in the retrieval models of transit spectra for hot Jupiters for a more accurate interpretation of the observed transit spectra.

; the distance ranges from 250 to about 1.5 kpc. These incomplete distance samples indicate a linear relationship between the distance and the radial velocity (V
LSR) with a scatter of 0.16 kpc, and kinematic distances may be systematically larger for local molecular clouds. In order to investigate fundamental properties of molecular clouds, such as the total sample number, the line width, the brightness temperature, the physical area, and the mass, we decompose the spectral cube using the density-based spatial clustering of applications with noise (DBSCAN) algorithm. Post-selection criteria are imposed on DBSCAN clusters to remove the noise contamination, and we found that the separation of molecular cloud individuals is reliable based on a definition of independent consecutive structures in l–b–V space. The completeness of the local molecular cloud flux collected by the MWISP CO survey is about 80%. The physical area, A, shows a power-law distribution, dN/d

, while the molecular cloud mass also follows a power-law distribution but is slightly flatter, dN/dM ∝ M

Motivated by the detection of a significant dipole structure in the arrival directions of ultra-high-energy cosmic rays above 8 EeV reported by the Pierre Auger Observatory (Auger), we search for a large-scale anisotropy using data collected with the surface detector array of the Telescope Array Experiment (TA). With 11 yr of TA data, a dipole structure in a projection of the R.A. is fitted with an amplitude of 3.3% ± 1.9% and a phase of 131° ± 33°. The corresponding 99% confidence-level upper limit on the amplitude is 7.3%. At the current level of statistics, the fitted result is compatible with both an isotropic distribution and the dipole structure reported by Auger.
Facultative scavenging feeding habits in Acanthurus chirurgus (Bloch, 1787) (Acanthuriformes: Acanthuridae)
Authors: Delgado-Pech Benjamín , Almazán-Becerril Antonio , Peniche-Pérez Jorge , Caballero-Vázquez José Adán
Published: July 2020

The family Acanthuridae is a key component of coral reef ecosystems as it controls macroalgae biomass buildup. During routine monitoring of benthic communities in the Mexican Caribbean, we observed unusual behaviour of a group of Acanthurus chirurgus, which were feeding on a tuna head left on site by travel tour personnel. This phenomenon has been documented in other herbivorous fish species, especially in places where tourism is a major coastal activity. Although many Acanthurus seek additional sources of protein by feeding on detritus, it is unusual for them to feed directly on fish flesh. Acanthurus chirurgus will incorporate proteins from animal tissues whenever the opportunity arises. Such opportunities occurred rarely in the past, but have become more frequent recently, related to increasing tourism activities where flesh is used as bait to attract the surrounding fauna.

A conservation checklist of the amphibians and reptiles of the State of Mexico, Mexico with comparisons with adjoining states
Authors: Lemos-Espinal Julio A. , Smith Geoffrey R.
Published: July 2020

The State of Mexico has a unique combination of geographic characteristics and topography that promotes a high biodiversity. Unfortunately, continued human population growth of the metropolitan areas of Mexico City and Toluca have degraded the environment of the State of Mexico, which threatened its wildlife. An updated checklist of the amphibians and reptiles of the State of Mexico is provided and their conservation status summarized. The State of Mexico has 49 species of amphibians and 101 species of reptiles. The majority of the amphibians (73.5%) and reptiles (70.3%) found in the State of Mexico are endemic to Mexico. Of the amphibian and reptile species in the State of Mexico, 20.1% are IUCN listed (i.e., Vulnerable, Near Threatened, or Endangered), 18.4% are placed in a protected category by SEMARNAT (excluding NL and Pr, this last category is equivalent to the LC category of IUCN), and 34.9% are categorized as high risk by the EVS. The importance of forested habitats for the protected amphibians and reptiles in the State of Mexico suggest that management of these habitats to maintain or expand them needs to be considered.

Green business and local economies
Authors: Sitkin Alan
Published: July 2020

The article focuses on how the green agenda can be progressed through practical steps at the local government level. The author draws on his time as a councillor in the London Borough of Enfield, where he combined his interests in regeneration and sustainability. He argues that environmental
sustainability should be viewed as a prime policy consideration in all levels of government; and that a green business logic should be applied when assessing the viability of initiatives in this area. Local government is in a relatively good position for green business investment. However,
the sums of money required mean that external counterparts and commercial interests are also needed. The article describes initiatives to support the local private green-tech sector, and the founding of a low-carbon heat-from-waste company, energetik, whose next stage involves building an
energy centre adjacent to the North London Waste Authority's waste facility.
Managing adoption by cultural development: Exploring the plant level effect of a ‘Company Specific Production System’ (XPS) in a Norwegian multinational company
Authors: Hekneby Torbjørn , Ingvaldsen Jonas A. , Benders Jos
Published: July 2020

Purpose: ‘Company Specific Production Systems’ (XPS) aim to adopt ‘best practice’ across plants within a company. A pertinent issue in the literature involves the constraints in the possibilities of realising such an adoption. This paper addresses to what extent and how a Norwegian multinational succeeded in adopting the XPS in its local plants.Design/methodology/approach: A Brazilian, Chinese and Norwegian plant of a Norwegian electro-chemical company were studied from 2017 to 2019. Our data consist of the results of the plant’s assessment performance program, combined with interviews and observations at different organizational levels. Findings: The MNC had largely managed to adopt the XPS in these plants. This was made possible by creating a strong corporate culture, shaping the managers’ basic assumptions, and persuading lower-level management and operators to adopt the improvement programme. The corporate culture was the result of several initiatives including the deployment of different HRM practices, supported by top management teams and by using the Norwegian plant as a laboratory visited by global operators and managers. Originality/value: This paper is, to our knowledge, the first to study the actual use of an XPS intra-organizationally. It highlights the role of culture development and basic assumptions for achieving global adoption. Global improvement programmes require constant managerial attention and actions at several levels in order to be adopted globally.
The challenges of institutionalization of musical knowledge
Authors: Le Gargasson Ingrid
Published: July 2020

Modern music institutions have ensured the permanence and renewal of musical practices and have on a broader basis fostered artistic creation. The development of music institutions and the crucial role they have played in the recent history of a great number of music traditions call for a transversal and anthropological reflection. Institutionalization generates an ensemble of processes that directly impact musical knowledge: it contributes to the redefinition of the social and geographical spaces of a given practice or repertoire. By focusing on the journey of a given practice or of a musical category, the authors of this special issue give evidence of the multiplicity of music contexts and the imbrication of institutions in different temporal and territorial scales. They also underline the agency of actors with regards to the coexistence and overlapping of socio-musical institutions. While the institutional context defines a performance space with a status that fluctuates in time and in the musical field, the dynamics generated by the interpenetration of different models of musical socialization draw a complex musical landscape with moving boundaries.

Structural Change and Magnetic Properties of Mechanically Alloyed Spinel Ferrite CoFe2O4
Authors: Idayanti Novrita , Dedi  , Manaf Azwar
Published: July 2020

Magnetic property studies and the crystallite structures evolution of spinel ferrite CoFe2O4 particles are reported in this paper. The ferrite was prepared through mechanical milling of all alloy precursors and sintered at various temperatures of 800, 900, 1000, and 1100 °C to promote the crystalline structure. X-ray diffraction (XRD) and Williamson-Hall plot were used to calculate the mean crystallite size and microstrain. Changes in the microstructure and crystallite sizes were occurring due to sintering treatments. It is found that the remanence (Mr) and saturation magnetization (Ms) increase with increasing sintering temperature, but a decrease occurred only at the temperature of 1100 °C. The optimum magnetic properties were obtained in a sample sintered at 1000 °C with a value of Mr = 36.00 emu/g and Ms= 74.05 emu/g.

Electron-doped superconducting cuprates of Eu2-xCexCu1-yNiyO4+a-d in under-doped region with x = 0.12 and y = 0, 0.01, 0.02, 0.03 and 0.05 have been prepared, characterized and investigated in order to study the effect of Ni impurity to the magnetic properties of electron doped superconducting cuprates. All main peaks of tetragonal and T’ structure configuration of ECCO were observed in all samples. Temperature dependence of dc magnetic-susceptibility on field cooling at 5 Oe for Eu1.88Ce0.12Cu1-yNiyO4+a-d with d values from 0.0496 to 0.08322 shows diamagnetic behavior for sample with y = 0, starting from about 11 K. For sample with y = 0.01, Tc onset decreases to be around 4 K. The superconductivity disappeared at y ≥ 0.02 indicating 2 % Ni substitution to the Cu has weakened the spin-spin correlation and reduced the value of magnetization in ECCO system.

We have succeeded in synthesizing electron-doped cuprates T’-Pr2-xCexCuO4 (PCCO) with x = 0 and 0.10 nanocrystals prepared by the chemically dissolved method. Reduction annealing of the PCCO samples at 700°C under a flowing argon gas atmosphere has been performed for the removal of excess oxygen in the apical sites. The XRD data showed that the reduction annealing process decreases c-axis length indicating successful removal of the excess oxygen. The bond distortion of PCCO including coordination number and bond distance between the absorber atoms with the nearest neighboring atoms (Cu-O) was investigated by extended x-ray absorption fine structure (EXAFS) using Cu K-edge. The implication of our results is discussed on the basis of tremendous influence of oxygen vacancies on the magnetism of the nanosized T’-cuprates at the normal state.

One of the important characteristics of magnetic materials is the measurement of magnetic characteristics through Superconducting Quantum Interference Device (SQUID) especially magnetization temperature dependence M(T)ZFC and MTFC measurement. In this work, we reported magnetization temperature dependence measurements of magnetite nanoparticles without SiO2 encapsulation (Fe3O4) and magnetite nanoparticles with SiO2 encapsulation (Fe3O4.SiO2) at the application of magnetic fields of 100 Oe. The nanoparticles magnetite was synthesized by co-precipitation method. It was calculated that the blocking temperature of magnetite nanoparticles Fe3O4 without and with SiO2 encapsulation is 118.38 K and 209.03 K, respectively. The blocking temperatures of magnetic nanoparticles increase by SiO2 encapsulation.

We investigated the stability of the high-spin state of the iron β-NaFeO2 based on the structural refinement. The oxidation of the Fe2+ ion in the as-synthesized sample is evidenced by its green color. Due to its sensitivity in air and CO2, this compound will decompose into a reddish Fe3+ state. The smaller crystal volume of the decomposed compound is mainly related to the shorter ionic radius of the high-spin state Fe3+ and this result will be compared to the single crystal sample. In contrast to the polycrystalline sample, the decomposition single crystal sample only taking place on the surface of the as-grown crystal.

We report the phase formation and electrical resistivity of MgB2 superconductor samples. Method of synthesis was conventional solid-state reaction employing crystalline β-rhombohedral boron (B) and magnesium (Mg) with a stoichiometric ratio of Mg:B=1:2. The two precursors were mixed and sintered at various temperatures from 600°C to 900°C for an hour. All samples were characterized employing XRD, SEM, and Cryogenic Magnetometer. It is shown that the MgB2 phase begins to form at a sintering temperature of 700°C. The highest peak intensity of the MgB2 phase was observed in a sample sintered at 900°C indicates the largest fraction of the superconducting phase among all synthesized samples. Electrical resistivity values were carried out to investigate the superconducting properties of the samples. It is also shown the samples sintered at a temperature of 800°C and 900°C possess superconducting properties with a critical temperature of ~ 43 K

In this paper, the magnetization reversal of sphere-shaped ferromagnetic nanoparticles has been investigated by means of micromagnetic simulation. Some ferromagnetic particles such as Cobalt, Iron, Nickel, and Permalloy were modeled with size variation from 50 nm to 100 nm. The discretization of the ferromagnetic model was used a cell size of 2.5×2.5×2.5 nm3 considering the exchange length (lex) of the materials. The quasi-static magnetic field was induced into the nanosphere to observe the magnetization response under time dependence. It is found that the coercivity values are decreased as the sphere size increased, which was conformed the experimental results. It is also observed that the domain structure of a single particle in remanent and ground-state condition are identical. Therefore, the specific understanding of magnetization process and domain structures in ferromagnetic nanoparticles could be an important step in the development of nanopatterned magnetic memory storage.

The XRD results show that the addition of Nd3+ doping increases the number of SrNdFeO4 phases. The phase has a tetragonal crystal system that has cell parameters a = b = 3.846 Å, and c = 12.594 Å. The magnetic properties of the material showed that the addition of Nd3+ decreased the saturation and remanence magnetization values, whereas the value of the coercivity field increased. Meanwhile, the best microwave absorption occurs in samples with the addition of Nd3+ as much as 0.3 mol, which results in a reflection loss value of -18.9 dB with a frequency bandwidth of 3.9 GHz.

Samples were processed with the solid reaction method through milling at seven hundred revolutions per minute for five hours. X-ray diffraction was used to characterize the phase formation and crystal structure. Scanning electron microscopy was used to see the shape and size of particles, while the vibrating sample magnetometer was used to measure magnetic quantities, which are: the coercivity field and magnetic saturation. All samples have a hexagonal structure, for samples x = 0 and 0.2 have a single phase, while for samples x = 0.4 and 0.6 other phases are detected. The shape of the particles are heterogeneous, with size ranging from 10-25 μm. All samples were not saturated even until the external magnetic field reaches 1 T. As the value of x increases, the magnetization will decrease. Samples substituted by Zn and Ti (x ≠ 0) have higher coercivity field values when compared to sample without substitution (x = 0).
