Effects of Psychological Factors and Academic Suppliers on Indonesian Students’ Academic Records and Career

Students’ academic records are an important part of students learning life. Academic records provide awareness to the observer about a student’s performance and forethought about the student’s future planning. Hence, insight against the factors that impact on academic records is very necessary. Although, there is a list of factors involved in the matter, however, psychological factors such as educational organization and teaching method play an essential role to build a better or junk academic record by a student. The current study has depicted the role of both the educational organization and teaching method, how these two can help an Indonesian student to make outstanding and exceptional academic records, which are necessary for the students to build a strong academic career. According to this study, a strong academic career is only possible when there are consistency and continuity of very good academic records for each class and course passed by a student. Statistical software; Partial Least Square was used for data analysis. Hence, for primary data collection, a survey was accomplished. Data analysis was completed to obtain final results based on the 395 responses received from the respondents of this study. Besides, our study provides a significant evidence for the fact that academic suppliers like family, student suppliers, and faculty suppliers are positively impacting on academic career of the students.
ADSORPTION AND DESORPTION OF M-XYLENE FROM SUPERCRITICAL CARBON DIOXIDE ON ACTIVATED CARBON

The equilibrium loadings of m-xylene from supercritical carbon dioxide on activated carbon are reported. The experimental data were obtained by measuring the outlet concentration of m-xylene eluted from a column packed with activated carbon until the effluent reached the input concentration. The Freundlich isotherm expression was found to correlate the experimental data satisfactorily. In a second step, the regeneration by supercritical carbon dioxide of activated carbon loaded with m-xylene was investigated. The experimental data demonstrated that the adsorptive capacities of the regenerated activated carbon for m-xylene after many cycles were close to those of the virgin carbon and remained stable. The effects of temperature, pressure, and flow rate on regeneration efficiency were also studied.
On-line X-ray diffraction for quantitative phase analysis: Application in the Portland cement industry

The aim of this work was to design, construct, install, and commission an on-line, X-ray diffraction (XRD) analyzer capable of continuously monitoring phase abundances for use in process plant control. This has been achieved through a joint project between CSIRO Minerals and Fuel & Combustion Technology Pty. Ltd. with an instrument designed for use in a Portland cement manufacturing plant. Key factors in tailoring such an instrument to the cement industry were (i) the handling and presentation of a dry sample and (ii) the development of an analytical method suitable for the complex suite of phases contained within Portland cement. The instrument incorporates continuous flow of sample through the diffractometer using a purpose-built sample presentation stage. The XRD data are collected simultaneously using a wide range (120° 2θ) position sensitive detector, thus enabling rapid collection of the full diffraction pattern. The data are then analyzed using a Rietveld analysis method to obtain a quantitative estimate of each of the phases present. The instrument is controlled by a PC linked to the diffractometer through a purpose built interface. The phase abundance information is then transmitted to the central computer in the cement plant where it can be used for the control of mill parameters such as temperature and retention times as well as gypsum feed rate.
Single‐Crystal Neutron Diffraction Analysis of Anion–Cation Interactions in Perdeuteroacetylcholine Bromide at 100 K

The interaction of the neurotransmitter acetylcholine with receptor binding sites has been well studied over the years, but much is still unknown about how intermolecular forces govern the lock-and-key fit. Here we present an analysis of cation-anion hydrogen-bond interactions in a single crystal of perdeuteroacetylcholine bromide, using pulsed neutron diffraction data to refine the X-ray crystal structure. The molecule crystallizes in space group P2 1 /n, with a = 10.951(4), b=13.396(8), c = 7.072 (4) A, β = 108.88 (3)°, Z = 4. The final refinement included anisotropic temperature factors on all atoms and converged to wR(F) = 0.055 (244 parameters). The pyramidal configuration of C-D-. Br - contacts observed in the crystal is in good agreement with ab initio molecular orbital predictions of favoured configuration and is consistent with a modest polarization of C-D bonds close to the N atom. There is evidence that close contact with Br - is hindered by the repulsive influence of the ester O atoms, dependent on the conformation of the acetylcholine cation. This is the most detailed picture to date of close interatomic contacts around the cation and analogies are drawn with the bonding of acetylcholine to its receptors.
Site specific photo-crosslinking of single stranded oligonucleotides by a complementary sequence equipped with an internal photoactive probe

The photo-crosslinking behaviour of oligonucleotide constructs, incorporating photoactive residues 1–5 at a defined position, has been examined in the presence of their DNA (14-mer) and RNA (15-mer) complementary targets using a two-fold excess; it revealed a moderate but promising irreversible binding efficiency, the results of which could be anticipated by molecular mechanics in the case of 4.
B2MML as an exchange format for asset administration shells as part of a plug-and-produce process for a fluid power engineering application

One development in the course of industrial digitalisation, which is being driven forward particularly in the German-speaking countries and will gain in importance in the future, is that of the Asset Administration Shell (AAS) [1]. The present work deals with the distribution, instantiation and use of those AASs for assets within the domain of a fluid power engineering application, which by themselves do not currently have the corresponding hardware and software for harbouring an AAS. The Business to Manufacturing Markup Language (B2MML) is used here for the deployment and instantiation of these AASs. In the present work, B2MML is extended with the concept definitions of AAS using its enhancement mechanisms. The distribution of the AASs to computing resources then takes place using B2MML and its transaction definitions. Furthermore, B2MML is used in a submodel to orchestrate process queues. In the course of the FL4 research project, B2MML is integrated as a partial model into the AAS and is used for orchestrating the Plug-and-Produce processes one the business and on subordinate levels.
A study into forces and moments acting on the swash plate of an axial piston pump using a novel approach to reduce pressure and flow pulsations

In hydraulic pumps, typically in axial piston pumps, reduction of pressure and flow ripples was attempted by providing relief grooves and pre-compression for noise reduction. Pre-compression is normally achieved by using the dead space between pump ports in the valve plate. Also valve plate profile modification is required, if system operating conditions such as pump output pressure and flowrate change, to maintain optimum operating conditions for reduced pressure/flow ripple. An earlier simulation study confirmed effectiveness of varying dead centre position to reduce pressure and flow ripples. A specifically designed mechanism, outlined in the earlier work, achieves this goal by varying the dead centre position of the pump swash plate. This study reports on the findings of the effect of varying dead centre position and groove configurations on forces and moments acting on the swash plate for various operating conditions. The simulation model cited in the earlier work was used in this study. This information is vital for the design of an actuating mechanism to vary dead centre position of a pump valve plate. These simulations were run using MATLAB/Simulink and S-functions. Results of this study are promising.
Impact of COVID-19 on Mental Health

The new COVID, later dubbed coronavirus, is an incurable disease that can be transmitted to humans. It originally appeared in late December 2019 in the Chinese city of Wuhan, where it documented cases of pneumonia of unclear etiology. After its rise, it marked as an episode that caused real concern for the general public by the WHO, and in the middle of January 2020, the WHO declared a global pandemic due to a dramatic increase in global diseases affecting many nations. More than 108 million cases had been validated worldwide as of February 14, 2021, with 5.99 million cases reported in the Eastern Mediterranean region. As a result of this global emergency, segregation and detention measures were being taken by international and governmental organizations to prevent the spread of the disease. Additional measures include airline suspension, large assembly congestion, and compulsory use of face masks in many countries, community evacuation, telephone work, child education, and home-based care. Conclusion: There is a need to build the mindfulness among the different media stages about mental difficulties during pandemics and feature the significance of looking for help and taking part in actual work for the administration of emotional well-being messes. Moreover, an increment in mindfulness among the medical care experts in recognizing and focusing on the high-hazard gatherings of the populace who are in danger in creating psychological well-being issues is crucially significant.
Non-thermal plasma assisted LKMO catalyst approach to NOx removal in diesel engine emissions

Abstract Perovskite type La0·8K0·2MnO3 (LKMO) was prepared by citric acid sol–gel method. X-ray diffraction, SEM and Brunauer–Emmett–Teller were used to characterise the products. The non-thermal plasma assisted catalyst (NPAC) system was established by combining the non-thermal plasma (NTP) reactor with LKMO catalyst. Following up on the bench test, NOx reductions in diesel emissions were investigated with the NPAC system. Results showed that NOx conversion reaches its highest level at 300°C with LKMO catalyst and at 200°C with the NPAC system. Improved catalytic properties of LKMO can be explained by the combination of the porous structure and the active species generated by NTP.
Design and optimization on rootstock cutting mechanism of grafting robot for cucurbit

Cutting mechanisms in existing grafting machines are unable to completely cut through the rootstock growth point and can easily damage seedlings. During the mechanical operation of splice grafting, the cutting angle of the rootstock is an essential factor for ensuring the quality and survival rate of grafting seedlings and a stable process for grafting robots. Therefore, in this study, commonly used grafting rootstocks, e.g., cucurbita moschata, and calabash gourd were used as research objects for studying and analyzing the cutting angle of a splice grafting method. The morphological and structural parameters of the rootstock and scion were measured, and a structural model of the internal cavity of the rootstock was constructed using an image analysis method. The critical cutting angles for the cucurbita moschata and calabash gourd seedlings were obtained. According to the analysis, the grafting cutting angles for cucumber seedlings matching with cucurbita moschata seedlings were 20° and 25°, respectively, and the fitting rate of the cutting surface of the rootstock and scion was 99.04%. A cutting mechanism for the rootstock growth point and geometric model of the cutting operation were established, and the structural parameters of the mechanism and cutting angle adjustment were optimized. A cutting performance test showed that the success rate of the pressing the cotyledons of cucurbita moschata seedlings was 96.67%, and the success rate of cutting was 98%. The cutting accuracy was 96.8%, and the cutting surface fitting rate of the rootstock and scion was 98.61%. The latter differed by 0.43% from the theoretical rate but met the requirements for the splice grafting method. Thus, this study can provide a reference for the design of a cutting mechanism for a grafting robot.

Brides’ expectations of their hotel stay: An exploratory study

This qualitative exploratory study is an examination of service-quality determinants in hotels from the perspective of brides staying at hotels before and after the wedding ceremony. Twenty semi-structured interviews revealed that the brides’ perception of the hotel experiences is composed of technical and functional factors, with emphasis on the quality of service. Findings indicated that hotels paid only minor attention to brides' wishes and desires regarding hotel-room features and critical service components. The brides expressed a clear expectation that the hotel servicescape would enable them to be at their best (physically and emotionally) in their center-of-the-show position. The findings have clear and immediate practical implications for the hotel industry to better tap the potential of this significant market segment, one all but ignored by scholars and practitioners.
Simulation of an interlocking hydraulic direct-drive system for a biped walking robot

Biped robots with serial links driven by an electric motor experience problems because the motor and transmission are installed in each joint, causing the legs to become very heavy. Previous solutions involved robots using servo valves, a type of highly responsive proportional valve. However, high supply pressure is necessary to realize high responsiveness and the resulting energy losses are large. To address this problem, we proposed a hydraulic direct-drive system in which the pump controls the cylinder meter-in flow, while a proportional valve controls the meter-out flow. Furthermore, our hydraulic interlocking drive system connects two hydraulic direct-drive systems for biped humanoid robots and concentrates the pump output on one side cylinder. The meter-in flow rate of the other side cylinder is controlled by the meter-out flow rate of the cylinder on which the pump is concentrated. A comparison of the walking simulation performance with that of the conventional independent system shows that our proposed system reduces the motor output power by 24.3%. These results prove the feasibility of constructing a two-legged robot without having to incorporate highly responsive servo valves.
Nucleation of Ice in Confined Geometry

Neutron diffraction studies have been made of ice nucleation in various forms of porous sol−gel silicas and ordered aluminosilicates. It is shown that the crystal structure of the ice exhibits significant variation according to the conditions and often has a diffraction pattern composed of a hybrid with both cubic and hexagonal ice characteristics. The ice structures appear defective/disordered in a complex manner but have common characteristics in terms of temperature variation studies. New studies of water in ordered mesoscopic (MCM-41) structures give results that appear to indicate “frustrated nucleation”.
Multidimensional flow mapping for proportional valves

Inverse, multidimensional input-output flow mapping is very important for use of valves in precision motion control applications. Due to the highly nonlinear characteristic and uncertain model structure of the cartridge valves, it is hard to formulate the modelling of their flow mappings into simple parameter estimation problems. This contribution conducts a comprehensive analysis and validation of threeand four-dimensional input-output-mapping approaches for a proportional pilot operated seat valves. Therefore, a virtual and a physical test-rig setup are utilized for initial measurement, implementation and assessment. After modeling and validating the valve under consideration, as a function of flow, pressure and temperature different mapping methods are investigated. More specifically, state of the art approaches, deep-learning methods and a newly developed approach (extPoly) are examined. Especially ANNs and Polynomials show reasonable approximation results even for more than two inputs. However, the results are strongly dependent on the structure and distribution of the input data points. Besides identification effort, the invertibility was investigated.
Digital Health Interventions for People With Type 2 Diabetes to Develop Self-Care Expertise, Adapt to Identity Changes, and Influence Other’s Perception: Qualitative Study

Background A diagnosis of type 2 diabetes (T2D) results in widespread changes to a person’s life and can be experienced as an assault on their sense of self. The resources available to an individual influence how the individual adapts to their diabetic identity and subsequently engages in self-care. Digital interventions can be viewed as a resource that people can draw on to adapt to the diagnosis. However, there is an indication that people from disadvantaged groups find digital health technologies more challenging to access and use, which may increase health inequalities. Objective This study aims to gain insights into how and why people with T2D use digital self-care technology and how experiences vary between individuals and social groups. Methods A purposive sample of people who had used a digital intervention to help them self-care for their T2D were recruited for the study. Semistructured interviews were conducted, and data were analyzed thematically. Results A diverse sample of 21 participants were interviewed. Participants used digital interventions to help them to understand and feel more in control of their bodies. Digital interventions were used by participants to project their chosen identity to others. Participants selected technology that allowed them to confirm and enact their preferred positive identities, both by avoiding stigma and by becoming experts in their disease or treatment. Participants preferred using digital interventions that helped them conceal their diabetes, including by buying discrete blood glucose monitors. Some participants used technology to increase their sense of power in their interaction with clinicians, whereas others used technology to demonstrate their goodness. Conclusions The technology that people with T2D have access to shapes the way they are able to understand and control their bodies and support preferred social identities.
The Effect of adding First Order Aberrations To Third Order Aberrations on Point Spread Function for Triangular Aperture

Received: 12 DED, 2019 Accepted: 25 MAR, 2020 Available Online: 16 SEP, 2020 In this work, Point Spread Function (PSF) for triangular aperture was studied, in case of ideal optical system, also in case of presence first order aberrations )focal error and tilt aberration) and third order aberrations (spherical ,coma, and astigmatism aberrations) individually, and for the same values of aberration factor )W=0. 1λ . 0.5 λ ) for angle of rotation (ѱ =0). First order aberrations were added to third order aberrations, to obtain the best balance and to reduce the curve width of the (PSF), and to increase the Strehl ratio, like adding a tilt aberration to the coma aberration and adding focal error to spherical aberration and astigmatism aberration. There are some aberrations effects impact negatively on point spread function, such as focal error with coma aberration and tilt aberration with spherical aberration.

Science Education Graduates of a State University from 2008-2018: A Tracer Study

This descriptive research determined the extent of employability of science education graduates from 2008-2018 in a state university in the Philippines. The study also ascertained the graduates' retrospective evaluation of the science education program in the aspects of adequacy and relevance. A total of 49 purposively selected graduates responded to the online survey questionnaire. Results revealed that there is a very high employability rate of the graduates of the university. Their educational experience and skills learned are very relevant in their current workplace. They evaluated the 10 program areas as good and indicated that the program outcomes are adequate and relevant. These graduates also suggested that content and pedagogy among pre-service teachers be enhanced. A curriculum review may then be considered for better alignment of the program to the demands of the 21st century learning landscape and to the fourth industrial revolution to produce industry-ready and globally-competitive science educators.
TIME‐DEPENDENT SORPTION OF PHOSPHATE BY SOILS AND HYDROUS FERRIC OXIDES

Summary The sorption of inorganic phosphate (P) by soils and hydrous ferric oxides was studied at times up to 192h. An initially rapid decrease in solution P concentration was followed by a much slower decrease between 48 and 192h with soils, Fe gel. and natural goethite, whereas synthetic goethite gave a well-defined equilibrium condition after only 48h. Resolution of the sorption isotherms showed that the increase in P sorption with time involved an appreciable shift of P from a more-physically sorbed form to a chemisorbed form. This was supported by chemical fractionation which showed that NaOH-extractable P was fairly constant with increasing sorption time, whereas the additional sorbed P was extracted by citrate-dithionite-bicarbonate from soils, and by HC1 from Fe gel and natural goethite. These sorbents contained short-range (amorphous) material, whereas synthetic goethite, from which all sorbed P was NaOH –extractable. did not. It is proposed that the time-dependent sorption of P and the associated shift of P to chemisorbed forms, involves the diffusion of P into “structurally porous”, short-range order material.
Virtually Real or Really Virtual: Towards a Heritage Metaverse

The hype surrounding the impending mainstreaming of Virtual Reality can seem to prioritize the digital above the critical. With the development of VR said to be at a pivotal point, there is an important opportunity to consider the emergence of virtual heritage and its potential futures. This paper argues that there is a disjunction between the present reality of virtual heritage and virtual reality and discusses the twin challenges of presence and realism within virtual reality. In particular, it highlights a paradox inherent in virtual heritage and virtual reality and proposes the use of ‘loose-realism’ as a solution. Ultimately, the challenge is to address the claims that virtual reality represents a new class of information system, or metaverse, in order that virtual heritage fully engages with inquiry about the past.
