Abstract:
The article describes methods of achieving painterly qualities while drawing with soft materials, which include: 1) creation of a polychrome image effect using an extremely limited color palette (white, black and red chalk (sanguine)); 2) thorough work on a multi-layer charcoal drawing employing techniques similar to those of multi-layer watercolor, oil and pastel painting, as well as papier-pelle drawing. The study was first conducted by analyzing drawing manuals, catalogs of manufacturers and suppliers of art materials from France, Great Britain, Germany, USA and Russian Empire in the second half of the 19th – early 20th century. What is more, the author of the article assembled a collection of antique tools and materials for drawing with charcoal, black chalk or crayon, stumping chalk (pulverized charcoal), sanguine and white chalk, the use of which was widespread in the aforementioned period. The annex to the article provides photographs of the described instruments and materials accompanied by the aggregate data from art manuals, catalogs and price lists of drawing material suppliers from London, Paris, New York, St. Petersburg, Moscow and Kazan, published over a period from 1851 to 1913. The drawing tradition of the second half of the 19th century is among one of the most complex and challenging in the entire history of graphics, as it peculiarly combines in itself a variety of instruments and delicate thoroughness of techniques. As a result of the research, the author was able to expand and complement the existing knowledge about graphic techniques, which allows for teaching academic drawing and studying the history of drawing by applying new data and unique illustrative material.

Abstract:
Fiber surface properties have a significant effect on yarn spinning. The frictional behavior of fibers greatly influences their processing, their performance and the performance of the final product. In order to investigate the effect of fiber surface properties and inter-fiber friction during spinning process, card slivers are taken and subjected to three drawing passages. Card and drawing frame slivers are then tested by the Static Friction Tester (SFT), which has been developed earlier. Fiber fineness, maturity and fiber length are measured by using different testing instruments. Hook content is calculated by utilizing fiber length data. The statistical analysis of results shows the same trend for the different cotton fibers tested.

Abstract:
Se il territorio costituisce il supporto materiale sul quale si sono impressi e sovrapposti i segni lasciati dall’uomo attraverso i secoli, la città può essere a ragione considerata la massima manifestazione dell’intervento dell’uomo su di esso. I processi urbani che determinano un impianto con tutte le sue modificazioni dinamiche sono interconnessi senza soluzione di continuità storica tanto da essere riassunti e rinvenuti nella trama stessa della città. Possedere gli strumenti per cercare di comprenderne i contenuti costituisce un primo atto cognitivo di fondamentale importanza qualora si intenda partecipare consapevolmente all’accumulazione di nuove proposte all’interno del tessuto storicizzato.La fase analitica della lettura conduce alla comprensione di questi processi dinamici che hanno determinato storicamente gli assetti insediativi e infrastrutturali del territorio. In analogia con la letteratura possiamo asserire che il palinsesto territoriale corrisponde al testo della storia dell’uomo e per essere compreso deve essere letto con la logica del progetto, lo strumento eletto della disciplina dell’architettura. Il documento principale per la lettura è il rilievo. Sottoporre la forma urbana di Pisa all’indagine sperimentale della lettura mediante l’adozione di nuovi strumenti digitali costituisce un momento di approfondimento e di sintesi delle conoscenze acquisite oltre ad esperire nuove metodologie analitiche sia nel campo degli studi storico-archeologici che in quelli dell’urbanistica e dell’architettura. I modelli tridimensionali digitali di Pisa e del suo territorio entrano per la prima volta a far parte di tale apparato strumentale, potenzialmente aperto verso nuovi possibili modi di utilizzazione. In particolare la Pianta della città si pone come supporto tecnico per molteplici e multiformi applicazioni.If the territory is the material support on where the marks left by man through the centuries are impressed and superimposed, the city could be rightly considerated as the greatest manifestation of the human intervention on it. The process that determine an urban system with all its dynamic changes are interconnected in a historical continuum so as to be summarized and found in the same interlaced city. To have the means in such a way as to try to understand its contents is primary importance if one intends to participate with good knowledge of a case in proposing new plans within the historical tissue. The analytical phase of reading leads to understand these dynamic process that have historically caused the settling down order and the territorial structure. On the analogy of the literature we can assert that the territorial palimpsest accords with the man history text and to be understood should be read with the logic of the plan, the elect instrument of the architectonic discipline. The main document for reading is the survey. To submit the urban form of Pisa to the experimental research of the reading by using new digital instruments is an opportunity of search and synthesis of the acquired knowledges besides to test new analithical methodologies both in the field of historical and archaeologic studies and in those of the town-planning and architecture. For the first time the digital threedimensional models of Pisa and its territory take part of this instrumental system, potentially open to new modes of use. Particularly the 3D representation of the town is a technical support for many and multiform applications. However, these new instruments of representation need to be connected with new methods of ‘reading’ and interpretation.KEYWORDS: 3D city model, G.I.S., territory and town, reading and typological interpretation

Abstract:
Musical settings that require consumers to construct their own musical instruments serve as potential sites of reconnection between musicians, the musical instruments they make, the natural resources that comprise those instruments, and the labor required to produce them. When musicians reconnect in these ways, they are able to understand and appreciate their musical instruments in new and meaningful ways. This can allow for heightened efforts in instrument care and maintenance; it can also allow for a greater sensitivity to environmental and ethical issues surrounding musical instruments. Data are drawn from a collegiate-level academic percussion musical setting where the musicians composed for and performed on the instruments they made themselves from mostly recycled materials. Group and individual semi-structured interviews and participant observation conducted over the course of summer and fall 2014 reveal the ways these reconnections are possible. This paper is in response to Matsunobu’s (2013) call to further establish instrument craft as an area within music education curricula.

Abstract Introduction The aim of this study is to determine if prior experience with fine motor hobbies influences a surgeon-in-training's performance on a cataract surgical simulator. Materials and Methods Medical students (n = 70) performed navigation, forceps, and capsulorhexis simulations using the Eyesi Ophthalmosurgical Simulator. Participants were surveyed regarding fine motor hobby experiences, including musical instruments, video games, sewing, knitting, origami, painting, crafting, jewelry making, drawing, and extracurricular dissection. Results Medical students with extracurricular dissection experience, including work in research laboratories involving microscopic animal dissection, did significantly better on the forceps simulator task (p = 0.009). Medical students with drawing experience performed better on capsulorhexis (p = 0.031). No other fine motor hobbies were significant for improving simulator scores. Conclusion Drawing and extracurricular dissection lend to improved technical ability on the cataract surgical simulator. This research continues the conversation regarding fine motor hobbies that correlate with microsurgical ability and adds to the growing area of research regarding the selection and training of ophthalmology residents.

Abstract:
This study deals with teaching and learning practices in vocational education and training (VET) in the Brazilian context. The objective of the research was to problematize the production of tutorial videos, as didactic resource - pedagogical, in the discipline “Drawing”, in a class of a higher secondary technical-professional education course. This is a particularly interesting topic due to the lack of teaching materials related to VET and the difficulties of using manual technical drawing instruments (and procedures execution ) observed in this discipline. The qualitative study adopted the action research method and was structured in three stages: video production, analysis of the video production process and intervention analysis. Held at the Federal Institute of Alagoas, Santana do Ipanema Campus, the research was carried out with students from the 1st grade of the Technical Course in Agriculture. Data collection focused on the written record and the application of two questionnaires: before and after the videos were produced. Participants rated positively the teaching experience they had. Our reflections suggest integration between the production of tutorial videos and the development of reflective teaching and learning practices. Thus, it is believed that the production of tutorial videos was positively constituted as a relevant didactic-pedagogical resource to the discipline “Drawing”.

Abstract:
The study aims to identify and describe the implementation of learning Culture and Arts (dance) by using WhatsApp at SMP N 11 of South Solok.This is a qualitative research by using descriptive method. The research instrument was the researcher itself and was supported by additional instruments such as a laptop, a camera, and writing instruments. Types of data used in this study were primary and secondary data. The data were collected through literature study, observation, and documentation. The steps of analyzing the data were reducing the data, presenting the data, and drawing conclusions.The results show that the implementation of online Culture and Arts (dance) learning in terms of material levels and dance patterns in class VII 1 of SMP N 11 South Solok by using WhatsApp runs very well although it is not maximized. This is due to the fact that the Basic Competence 4 could not be implemented. Judging from the planning, the learning design carried out by teachers remains the same but the steps for implementation are different because the learning system uses WhatsApp application. Teachers are more flexible in using media for learning. Teachers used to only use textbook media, now the media used are more interesting with the use of power points and videos from YouTube sent to WhatsApp group. In terms of assessment, it is conducted by looking at the assignments submitted by students and quiz scores. In term of implementing learning materials of knowledge, basic competence 3 is carried out very well. It is seen from the results of the assignments submitted by the students. There are no students whose grades were below the cut score. Even though in the submission of the assignments students are often not on time because of the internet’s load problem, the results of the submitted assignments are good enough and can even be more than the materials provided by the teacher. This proves that the students can look for additional materials other than what the teachers provide.Keywords: Implementation, Learning, Culture and Arts (Dance), WhatsApp

The emergence of multimaterial fibers that combine a multiplicity of solid materials with disparate electrical, optical, and mechanical properties into a single fiber presents new opportunities for extending fiber applications. Different functional fiber devices have been fabricated with a thermal co-draw approach. In order to make the thermal co-draw feasible, only materials with similar viscosity at the draw temperature are used, which excludes a wide range of metal and semiconductors that have good electrical property but not compatible viscosity profile. From the fiber structure point of view, the nature of the fiber drawing process makes fabricating a large quantity of fiber with identical inner structures feasible. The scalability of thermal drawing approach offers access to large quantities of devices however constrains the devices to be translational symmetric. Lifting this symmetry to create discrete devices in fibers will increase the utility of fiber devices. Also, the surface of the fiber is rarely studied though complex inner structure have been fabricated for different functionalities. Functionalize the fiber surface would give fiber the ability to better interact with the outer environment. This thesis seeks to address the abovementioned considerations, i.e. to expand materials selection for the fiber co-draw process and to explore variance of the fiber structure including breaking the inner structure translational symmetry and functionalize the outer surface. On the material side, a chemical reaction phenomenon is observed and studied in two different fiber drawing situations. In both cases, new composition is formed during the draw and play an important role in the formed fiber devices. On the structure side, relying on the principle of Plateau-Rayleigh instability, the fiber inner structure is designed to form a series of discrete semiconductor spheres contacting two metal buses after a thermal selective breakup process. This gives rise to photodecting devices in a silica-cladding fiber which shows a large working bandwidth. The fiber surface is also studied and successfully patterned with micron-scale features during the draw process. The formed patterned fiber surface shows potential in structural coloration and directional wetting.

The treatment of neurodegenerative and neurological conditions relies on better understanding the system that they afflict. However, the tools currently available to probe neural circuits are often limited to use in short-term studies primarily due to poor of biocompatibility. To address this challenge, flexible, minimally invasive neural probes were fabricated using a thermal drawing process, with polymers serving as their main structural constituent. Through the use of different polymers, probes containing arrays of tin electrodes as small as 5 [mu]m were fabricated, as were probes combining capabilities for electrical recording, optical stimulation, and drug delivery. A technique was developed to combine functionalities of these devices into a single probe to study the effect of optical stimulation with different waveforms on the brain activity. To break the longitudinal symmetry inherent to probes fabricated using the thermal drawing process, and to allow the incorporation of functionalities along the probe length, a method to combine thermal drawing with a method commonly used to fabricate neural probes, photolithography, was developed, along with the selection of the polymer that would allow consecutive processing using these two techniques. All of the fabricated probes were characterized and tested in vivo by implantation into mice and assessing their functionality. High signal-to-noise ratio (13±6) recordings were obtained using multielectrode arrays. Recordings of neural activity during simultaneous optical stimulation and drug delivery were performed with multifunctional probes. Hybrid probes combining metal electrodes with a polymer waveguide were used to study the response of large groups of neurons to different forms of optical stimuli. Most importantly, the biocompatibility of these probes was assessed over a 3 month period and compared favorably to that of steel microwires of similar size.

Full text
Abstract:
There is little information on the microbial contamination of orthodontic materials received from the manufacturer and if orthodontists pre-sterilise new products prior to use. These items may also become contaminated on the clinic or during laboratory construction. Recent regulations for decontamination in primary dental care (HTM 01- 05) have been introduced requiring a 60 day limit for storage time of sterilised instruments. The aims of this investigation were to determine whether components of fixed and removable orthodontic appliances are free from microbial contamination prior to clinical use; to establish the current practice in orthodontics with regard to pre- sterilisation of new products and to investigate possible re-contamination of sterilised dental instruments. A range of orthodontic materials "as received" from the manufacturer and "bench-top exposed" items were investigated. Bacterial contamination during the construction of removable appliances was evaluated from initial impression, through to delivery of the final appliance. Molecular microbiological techniques were used to obtain bacterial DGGE profiles and facilitate 16S rDNA identification. Questionnaires were distributed to consultant orthodontists to determine their current pre-sterilisation regimes for new orthodontic products. Twenty five dental mirrors were sterilised. These were tested (5 mirrors at each time point) for microbial contamination immediately after autoclaving and then at 31,60,90 and 124 days. Bacteria were isolated from "as received" bands, archwires and impression trays, but the level of contamination was low (0-3.65x102 cfu ml"). This was similar for clinic items. Much higher levels were found on removable appliances (0.97x102-1.52xl03 cfu mll ). There was no cross-contamination from patients to the laboratory; contamination occurred within the laboratory itself. The majority of consultant-led departments do not pre-sterilise materials from the manufacturer (88-97%). There was no bacterial growth from sterilised dental mirrors after 5 days of incubation at 37°C at any time period from 0 to 124 days post sterilisation. In conclusion, materials and appliances are not free from bacterial contamination prior to use in patients; improved cross infection control procedures are needed within the orthodontic laboratory. There is no current evidence for the 60-day storage of sterilised dental instruments as advised by the Department of Health.

Abstract:
Includes bibliographical references.
A study has been made of the fatigue crack initiation and fatigue crack growth behaviour of three different steels in wire form, namely, an austenitic AISI 304 stainless steel, a corrosion resistant ferritic steel, 3CR12, and pearlitic high carbon steel. The stainless steel wires were produced in the laboratory at a drawing speed of 50 mm min-1, without intermediate annealing, whilst the high carbon pearlitic steel was manufactured commercially. Studies were made on stainless steel wires as a function of drawing strain between 0.09 and 0.585. Fatigue testing was carried out on an ESH servo hydraulic testing machine on both notched and unnotched samples and the S-N curves were used to evaluate the fatigue properties of the steels. Tests were performed with sinusoidal loading and load ratios of R= 0.048 and R=0.22 at a frequency of 2Hz. The microstructural evolution during drawing was characterised by optical and transmission optical microscopy, and x-ray diffraction. Fatigue crack growth and fracture surfaces were studied using scanning electron microscopy. In general, the fatigue limit was enhanced by increased drawing strain, but such strain also increased the subsequent crack propagation rates. The highest value of fatigue limit of 630 MPa was exhibited by the commercial pearlitic steel despite of its high notch sensitivity. Both shot peening of the steel wire surface and reducing the surface roughness by manual polishing increased the fatigue limit between 40 and 25 % respectively. The fatigue limit of AISI 304 stainless steel wire was improved from 215 MPa to 650 MPa after drawing to 0.585 strain. This improvement is attributed to the deformation-induced phase transformation of (ϒ) austenite to α'-martensite. X-ray diffractometer traces show that the amount of strain-induced martensite varied from 8% in the wires drawn at low strain (0.09) to 36% in the wire samples drawn to 0.585 strain. This study has established that approximately 20% of deformation-induced martensite, through drawing strain, is a critical amount which determines the subsequent fatigue response of this steel. If the amount of previously developed martensite is less than the critical amount of 20%, the martensite formed during the fatigue process will act beneficially by retarding fatigue cracking, raising the fatigue limit and resulting in a ductile fatigue fracture surface. However, in the presence of more than 20% of martensite, any martensite induced by cyclic strain will encourage more rapid crack initiation compared to a material containing less than 20% martensite which leads to more brittle fracture surface characteristics. The fatigue limit of 3CR12 steel wire was also improved from 130 MPa to 310 MPa (maximum stress) after drawing to 0.68 strain. The experimental results indicate that the use of drawn 3CR12 ferritic steel for wire application under cyclic conditions is restricted to low stress levels. However, the application of heat treatment and the resultant development of a dual-phase microstructure, improved the fatigue limit to 470 MPa. Based on the findings in this study, recommendations regarding material selection and drawing process optimisation for wire production to improve the fatigue performance of AISI 304 stainless steel is given.

Abstract:
Design and engineering in real-world projects is often influenced by reduction of the problem definition, trade-offs during decision-making, possible loss of information and monetary issues like budget constraints or value-for-money problems. In many engineering projects various stakeholders take part in the project process on various levels of communication, engineering and decision-making. During project meetings and VE sessions between the different stakeholder’s, information and data is gathered and put down analogue and/or digitally, consequently stored in reports, minutes and other modes of representation. Results and conclusions derived from these interactions are often influenced by the user’s field of experience and expertise. Personal stakes, idiosyncrasy, expectations, preferences and interpretations of the various project parts could have implications, interfere or procrastinate non-functionality and possible rupture in the collaborative setting and process leading to diminished prospective project targets, requirements and solutions. We present a hybrid tool as a Virtual Assistant (VA) during a collaborative Value Engineering (VE) session in a real-world design and engineering case. The tool supports interaction and decision-making in conjunction with a physical workbench as focal point (-s), user-interfaces that intuit the user during processing. The hybrid environment allows the users to interact un-tethered with real-world materials, images, drawings, objects and drawing instruments. In course of the processing captures are made of the various topics or issues at stake and logged as iterative instances in a database. Real-time visualization on a monitor of the captured instances are shown and progressively listed in the on-screen user interface. During or after the session the stakeholders can go through the iterative time-listing and synthesize the instances according to i.e. topic, dominance, choice or to the degree of priority. After structuring and sorting the data sets the information can be exported to a data or video file. All stakeholders receive or have access to the data files and can track-back the complete process progression. The system and information generated affords reflection, knowledge sharing and cooperation. Redistribution of data sets to other stakeholders, management or third parties becomes more efficient and congruous. Our approach we took during this experiment was to [re]search the communication, interaction and decision-making progressions of the various stakeholders during the VE-session. We observed the behavioral aspects during the various stages of user interaction, following the decision making process and the use of the tool during the course of the session. We captured the complete session on video for analysis and evaluation of the VE process within a hybrid design environment.

Porcel Magnusson, Cristina. Unsettled Topics Concerning Coating Detection by LiDAR in Autonomous Vehicles. SAE International, January 2021. http://dx.doi.org/10.4271/epr2021002.

Full text
Abstract:
Autonomous vehicles (AVs) utilize multiple devices, like high-resolution cameras and radar sensors, to interpret the driving environment and achieve full autonomy. One of these instruments—the light detection and ranging (LiDAR) sensor—utilizes pulsed infrared (IR) light, typically at wavelengths of 905 nm or 1,550 nm, to calculate object distance and position. Exterior automotive paint covers an area larger than any other exterior material. Therefore, understanding how LiDAR wavelengths interact with vehicle coatings is extremely important for the safety of future automated driving technologies. Sensing technologies and materials are two different industries that have not directly interacted in the perception and system sense. With the new applications in the AV industry, multidisciplinary approaches need to be taken to ensure reliability and safety in the future. Unsettled Topics Concerning Coating Detection by LiDAR in Autonomous Vehicles provides a transversal view of different industry segments, from pigment and coating manufacturers to LiDAR components and vehicle system development and integration. The report includes a structured decomposition of the different variables and technologies involved.

The cassava seed system in Nigeria: Opportunities and challenges for policy and regulatory reform. International Potato Center, 2020. http://dx.doi.org/10.4160/23096586rtbwp20202.

Full text
Abstract:
In many African countries south of the Sahara, farmers depend on the cultivation of vegetatively propagated crops (VPCs) for both consumption and commercial purposes. Yet yields for these crops remain at low levels due, in part, to the persistent use of low-quality planting material. Efforts to improve the quality of planting material exchanged in markets or through other channels are often hampered by the unique biological and economic characteristics of vegetative propagation—characteristics that distinguish VPCs from the major cereal crops that drive and shape the policy and investment choices made in many of these countries. This suggests that continued investment in new technologies and systems to produce, package, and distribute VPC planting materials will require customized policies and policy support if these systems are to supply farmers with quality planting material at any significant and sustained scale. This paper explores these issues in the context of the cassava seed system in Nigeria by drawing on (1) prior research, public policy documents, and government statistics; (2) key informant interviews and focus group discussions with seed system actors; and (3) a unique dataset from the 2015 Cassava Monitoring Survey of Nigeria (CMS). The paper examines the production and supply of cassava planting material, the influence of various quality assurance systems on production and supply, and the implications for smallholder farmers in Nigeria. We describe the market, non-market, and regulatory systems that shape the cassava seed market in Nigeria, focusing on effectiveness, influence, and reach. We then explore the ground realities—how farmers actually acquire and use cassava planting material—given the (weak) state of markets and regulation. This is followed by a discussion of alternative policy and regulatory approaches to managing and expanding the cassava seed system, emphasizing a more decentralized approach that prioritizes investment in innovative capacity at the community and enterprise levels.
