The Collision of the Experiential and Existential in the Brain/Heart-Mind/Soul Continuum

Focused in the physical, people are primarily experiential learners. Yet with the creation and sophistication of measurement techniques at the turn of the century, an understanding of experiential learning from the inside-out began to expand through neuroscience. There was recognition that people are holistic beings, and that the heart and mind are an integrated, biological, and complex part of the embodied human system. And within this system, through research in neuroscience, there are hints of what is possible. There is a brain/heart-mind/soul continuum, which brings to mind and to soul the potential for an existential state of learning while focused in the physical/etheric reality. Whether played out in the “virtual reality” of the mind or psychecology educational games, this existential state of creating, imagining, experiencing, and learning can fully engage our creative imagination while simultaneously engaging our higher mental faculties. In essence, through existential experiencing we are creating a symmetry, becoming the mirror of our soul. As above, so below.

Characteristics of Abs and Pla Material in 3D Printing for Car Backseat Headrest Hanger/Hook Model

Additive manufacturing (AM) is known as the technology which enable using a layer wise in fabrication of a complex part directly from CAD files without using any specific tooling. This manufacturing techniques offers many strategic advantages which include design freedom for the build of complex part geometries which cannot be made in other way, the ability to build functional part in a small size for the end user customization and its ability to do improvement for the expensive part in aerospace and other industries. The aim of this research is to study the effect of process parameter such as layer thickness, infill density and object orientation to the accuracy of printed part measurement with CAD model, surface roughness and mechanical strength of PLA and ABS material. Therefore, it is important to find the optimum value of dimensional accuracy, surface roughness and mechanical strength for both materials. To achieve the optimum value of dimensional accuracy, surface roughness and mechanical strength for both materials, Taguchi method L4 orthogonal array is used to conduct this experiment and Minitab 18 software will analyze the result and shows the best optimum value. The result from ANOVA analysis shows that object orientation gives highest contribution to the dimensional accuracy and surface roughness for both materials. Meanwhile, for mechanical strength layer thickness highly contributed to the ABS material and object orientation for the PLA material. A Car Backseat Headrest Hanger/Hook model is fabricated by the best optimal combination and level of process parameter of mechanical strength.

Hybrid manufacturing of topology optimized machine tool parts through a layer laminated manufacturing method

Load-oriented lightweight structures are commonly designed based on topology optimization. For machine tool parts, they enable the reduction of moving masses and therefore increase the resource and energy efficiency of production systems. However, this usually results in complex part structures that are difficult or impossible to produce using conventional manufacturing methods. In this paper, a hybrid layer laminated manufacturing (LLM) method is proposed enabling manufacturing of topology-optimized machine tool parts. The method is referred to as hybrid, as the subtractive structuring of metal sheets is combined with the additive joining of the sheets by adhesive bonding. This enables enclosed inner cavities without support structures, which are used to approximate the optimal density distribution from a topology optimization via manufacturing. The proposed LLM method is validated on the basis of a bearing block of a ball screw feed drive. A experimental study in the time and frequency domain on a test rig confirms the principle suitability of the LLM method for the production of industrial applicable lightweight components.

Extracellular Matrix in Human Craniofacial Development

The extracellular matrix (ECM) is a highly dynamic amalgamation of structural and signaling molecules whose quantitative and qualitative modifications drive the distinct programmed morphologic changes required for tissues to mature into their functional forms. The craniofacial complex houses a diverse array of tissues, including sensory organs, glands, and components of the musculoskeletal, neural, and vascular systems, alongside several other highly specialized tissues to form the most complex part of the vertebrate body. Through cell-ECM interactions, the ECM coordinates the cell movements, shape changes, differentiation, gene expression changes, and other behaviors that sculpt developing organs. In this review, we focus on several common key roles of the ECM to shape developing craniofacial organs and tissues. We summarize recent advances in our understanding of the ability of the ECM to biochemically and biomechanically orchestrate major events of craniofacial development, and we discuss how dysregulated ECM dynamics contributes to disease and disorders. As we expand our understanding of organ-specific matrix functionality and composition, we will improve our ability to rationally modify matrices to promote regeneration and/or prevent degenerative outcomes in vitro and in vivo.

Mental rotation ability predicts the acquisition of basic endovascular skills

Due to the increasing complexity of diseases in the aging population and rapid progress in catheter-based technology, the demands on operators’ skills in conducting endovascular interventions (EI) has increased dramatically, putting more emphasis on training. However, it is not well understood which factors influence learning and performance. In the present study, we examined the ability of EI naïve medical students to acquire basic catheter skills and the role of pre-existing cognitive ability and manual dexterity in predicting performance. Nineteen medical students practised an internal carotid artery angiography during a three-day training on an endovascular simulator. Prior to the training they completed a battery of tests. Skill acquisition was assessed using quantitative and clinical performance measures; the outcome measures from the test battery were used to predict the learning rate. The quantitative metrics indicated that participants’ performance improved significantly across the training, but the clinical evaluation revealed that participants did not significantly improve on the more complex part of the procedure. Mental rotation ability (MRA) predicted quantitative, but not clinical performance. We suggest that MRA tests in combination with simulator sessions could be used to assess the trainee’s early competence level and tailor the training to individual needs.

A thermoplastic resin matrix and its physical properties suitable for deformable mandrel

The mandrel is able to shape the part cavity, therefore is of great significance for composite parts in the manufacturing of carbon fiber reinforced polymer(CFRP) composite part. However, in the manufacturing of composite parts with complex cavities, traditional rigid mandrel cannot be removed out of the cavity in any direction after the outer prepreg is cured. To solve the problem of difficult demolding, a kind of deformable mandrel emerged. The deformable mandrel is rigid at room temperature to support composite part curing. While at relatively high temperatures, the mandrel is softened so that the mandrel can be easily removed from the composite part despite the complex part cavity shape, therefore resolving complications regarding the demolding process. In this paper, a thermoplastic resin material matrix suitable for the preparation of deformable mandrel is proposed. Ingredient and manufacturing flow of the thermoplastic resin matrix are introduced, and the applicability of the proposed matrix with regard to the deformable mandrel is validated through dynamic mechanical analysis.

The role of soil in saving human race from COVID-19 pandemic

Soil is the most complex part of land as its contents are made of all the other key components of land namely geology (soil minerals), hydrology (soil water), atmosphere (soil air), and organisms including man (soil organic matter including dead bodies). This is why the functions of the soil are not only numerous but also indispensable. Among the functions, the role of the soil in sustaining human life remains unimaginable. Over 3.8 million people have been killed by COVID-19 by June 15, 2021 in the world and more are still dying. Some unrecorded millions died of hunger as a result of the lockdown during the peak of COVID-19 pandemic. Where are these dead bodies and materials associated with those that died of COVID-19? Where did all the food palliatives (rice, maize, wheat, yam, gari, vegetable oil, etc.) come from? The human body is composed of approximately 64% water, 20% protein, 10% fat, 1% carbohydrate, 5% minerals. When decomposed these various components result to various gaseous compounds and residues that are harmful to human life and environment. When dead bodies are buried human health and environment are saved. The dead bodies, the wastes and their contents are in the soil providing “palliatives” to soil microorganisms while protecting the remaining human population and the environment. Cremation products also end up in the soil. The soil also provided and still provides the food palliatives. Thus, the soil is our number one saviour against COVID-19 pandemic and can be adjudged as the saviour of the human race to date. Coincidentally man was made from the soil and must return to the soil. Key words: soil functions, burial, cremation, palliatives, COVID-19

Taxonomy of ‘Euconnus complex’. Part XXIII. Status of Napochus Thomson, Pycnophus Casey, and Filonapochus Franz revisited (Coleoptera, Staphylinidae, Scydmaeninae)

In previously published parts of this long-term study, subgenera Napochus Thomson and Pycnophus Casey of Euconnus Thomson were tentatively maintained, based on detailed morphological examination of their type species. Since then, many more species have been studied, including several hundred nominal Euconnus s. str., Napochus, and Pycnophus spp., and over a thousand presumably undescribed species collected on all continents. Considering character variability, current diagnoses of Napochus and Pycnophus were found to largely overlap with that of Euconnus s. str., and many species show intermediary features. In the present study, examples of such intermediary or transitional characters are illustrated, and character variability within the Euconnus s. str. + Napochus + Pycnophus morphological group is discussed. Available morphological evidence strongly supports a concept of a highly diverse Euconnus s. str. that includes Napochus and Pycnophus. Consequently, Napochus syn. n. and Pycnophus syn. n. are merged with Euconnus s. str. as junior synonyms. In addition, examination of the type specimens of the type species of Glandularia L.W. Schaufuss and Connophron Casey, both names currently treated as junior synonyms of Napochus, confirms the previously established synonymies. Characters of the previously revised subgenus Filonapochus Franz were also found to fall within the variability revealed in the present study, and also Filonapochus syn. n. is placed as a junior synonym of Euconnus s. str.
