Application of parametric design and digital fabrication: the solution for the current crises and emergencies
Authors: Díaz Valdés Mauricio 
Published: December 2021

During the next decades the construction will have to face many problems that never had inferred, it must reinvent itself to adapt to the new needs that it currently demands because it consumes too many energetic resources, it generates excess of CO2 emissions, consumption of natural resources and every day the construction is more expensive. The United Nations 2030 Agenda announced the objectives for sustainable development, this to try to mitigate the effects of climate change; The Coronavirus pandemic made humanity reflect on the emergencies that we must face and left us reflecting that we are not prepared for an emergency or crisis; These are key points that we must address to develop the new architecture. If we analyze the history of architecture, we can see that technology and science has always been a catalyst for humanity and has generated great solutions to the problems that befall us, this should motivate us to use technology and software in our favor. Therefore, we must prepare and generate new solutions, innovations and technology that focus on solving the new needs that architecture demands. The question is: how we can solve these problems? The answer is through digital fabrication and parametric design. It is important to emphasize and make it clear, we cannot continue to build as we have been doing in the past century, our practices and approaches must change, and it is urgent to rethink the role of the architecture today.

The Urban Image Conservation and Development of Nakhon Si Thammarat’s Old Town Community in Thailand
Authors: Thinnakorn Wirut 
Published: December 2021

Nakhon Si Thammarat Old Town Community dated a thousand years old from four eras of settlement development. The community is located on an ancient beach ridge that stands until the present day. It also has an image of a community that is unique to any city. Today the community is rapidly expanding, so the importance of the old town’s various elements has been diminished. The research objectives are to analyze Nakhon Si Thammarat Old Town Community’s image and landscape and provide suggestions to preserve and develop the community’s image. The methodology is theoretical concepts of the image of the city, urban landscape, historic urban landscape, and urban conservation, including field surveys to identify problems and the community’s awareness. Visual assessments and mapping were also undertaken. Based on the study, the urban conceptual framework emphasizes the five elements of physical perception, whereas the cultural landscape concept focuses on the physical perception of the community’s core components and sub-elements that express specificity of the district, including traditional custom, which is intangible culture and a landscape element as well.
The analysis of urban image reveals that Nakhon Si Thammarat Old Town Community consists of the path in the area with Ratchadamnoen Road, Karom Road and Pattanakarn Khukwang Road as the main routes, the edge of the community divided by natural boundaries, which are various rivers and by man-made boundaries, which are canals and the old city’s embankments, and the unique district, such as Tha Wang Community, Khaek Market Community, and Nakhon Si Thammarat Old Town. The node or activity center is, for example, business activities in Tha Wang Community, Khaek Market Community and Hua It Market Community, and the tourism activities in the old community area around Phra Mahathat Woramahawihan Temple. The prominent landmark from the past to the present is Phra Borommathat Stupda. In addition, the unique physical elements in the old town are groups of large trees. Suggestions on conservation and development are to create awareness of secondary routes to reduce congestion of the main roads and connect to other attractions; to develop the old town’s border from four eras for clearer perception; to promote the main activities within each district; and to have measures to control the height, billboards, old buildings’ styles, and new buildings representing each district’s uniqueness that will not obscure the perception of the community’s landmarks.

On the seismicity and tectonic activity Of the Bengal basin
Authors: SINGH V. P. , SHANKER D. 
Published: December 2021

The tectonic activity of the Bengal basin for years 1850-1988 of seismicity and 16 years (1970-1985) of P-wave first motion data have been studied. The seismicity studies reveal three seismic belts such as Dhubri fault (striking N-S), Calcutta hinge zone (striking NE-SW) and the central region of the Bengal basin (striking NW-SE). Dauki fault is comparatively less seismically active than Dhubri fault. The seismicity of Dhubri fault and Calcutta hinge zone are confined to limited extension. The seismic activity along the central portion of the Bengal basin is extending from the Himalayan region (27°N, 88.5°E) to eastern plate margin (23.8°N, 92°E). .This appears to be a tectonic belt and is associated with the northeast drifting of Indian plate. The focal, mechanism studies reveal thrust faulting showing the stresses to be perpendicular to the proposed belt.
What Has Changed in European Concept of Undertaking? From „FENIN“ to „EASY PAY“
Authors: Kalesná Katarína 
Published: December 2021

Competition is the main self-regulatory principle of the market in general, internal market included. Competition law has the form of general clauses making its application dependant on the correct interpretation of general concepts. Core competition rules of the Functional Treaty („TFEU“) are addressed to undertakings; undertaking thus belongs to key concepts of competition law. Interpretation of this concept is decisive for the scope of competition rules application. So, the article explores different approaches of the case law to the interpretation of the concept of undertaking based on economic activity. It compares the FENIN doctrine and the new functional test of separability developed in EASY PAY. It drives attention to the impact of this new test for the evaluation of procurement activities under competition scrutiny.

Projection radiography of the ankle; the views used for different indications vary between medical imaging departments
Authors: Guðjónsdóttir Jónína , Haraldsdóttir Silja 
Published: December 2021

Plain radiographs are used for initial evaluation of many conditions of the ankle. Many different radiographic views are described in positioning textbooks but evidence on which views to use, in which case, is scarce. The aim of this study was to map imaging procedures related to four indications for ankle projection radiography. A questionnaire was sent to all medical imaging departments in Iceland with questions about acquisition technique for ankle radiography views and which views were used for selected indications. Answer was received from 14 of the 28 departments. All departments gave very similar descriptions of the four most common views. In the case of trauma, all but one department used four views but for control of trauma or operation, four different combinations of views were found using from two to four images. For detrition and osteomyelitis, four views were more common in the larger departments but there was not a statistically significant difference. Eight different combinations of the number of views for the four indications were found. The study indicates that there is a need for standardization in image acquisition protocols. More studies are needed to support decisions about how many views are necessary for the most common ankle radiography indications.

Acquired Von Willebrand Disease
Authors: Viola Filomena Gemma Rinalda , Bellincampi Lorenza , Bernardini Sergio 
Published: December 2021

Abstract

Acquired von Willebrand disease (AVWD) is a heterogeneous, life‐threatening and bleeding disorder, usually associated with underlying disorders ranging from lympho‐ and myeloproliferative disorders to certain type of solid tumours, autoimmune diseases, cardiovascular disorders and drug therapies. AVWD is a complex multicausal disorder that is very often underdiagnosed or misdiagnosed. AVWD is usually characterised by a negative personal or family bleeding history and a late onset, even if it has to be considered in childhood. It is characterised by several different pathogenetic mechanisms, but all of them cause low circulating levels of von Willebrand factor (VWF), even if normally synthesised and released. VWF plays an important role in haemostasis, participating actively in platelet–subendothelium and platelet‐to‐platelet adhesion, promoting platelet aggregation and is a carrier protein for coagulation factor VIII. No simple, single laboratory test is available to screen for AVWD, and this makes it very challenging for clinicians to diagnose and treat the disorder. AVWD diagnosis requires a very experienced laboratory and is made using several specific laboratory tests.

Key Concepts

Primary haemostasis: pivotal role of von Willebrand factor (VWF) in platelet aggregation and adhesion.

VWF protein's quaternary structure and its functional role.

Congenital or acquired VWF deficiency.

Acquired von Willebrand disease (AVWD) is a bleeding disorder characterised by mucocutaneous bleeding; although AVWD has, generally, a mild clinical impact, it must be seriously considered in some medical conditions.

Role of autoantibodies and metalloproteases in AVWD.

Clinical chemistry laboratory tests have an important function in the diagnosis of AVWD.

Desmopressin achieves the main treatment goals of AVWD, such as control acute bleeding and prevent bleeding in high‐risk situations.
Circulation in Vertebrates
Authors: Farrell Anthony P , Eliason Erika J 
Published: December 2021

Abstract

The vertebrate circulatory system consists of a central pump (the heart), a system of tubes (the vascular and lymphatic vessels), fluid (blood and lymph) and a control system (neural, endocrine, paracrine and autocrine factors) that serves to transport gases, nutrients and other substances around the body.

Key Concepts

Gases, nutrients, immune factors, and products of metabolism are transported in the blood around the body through a closed network of branching blood vessels.

The heart is a muscular pump with a specialised pacemaker region that normally initiates the heartbeat, though heartrate is modified by sympathetic and parasympathetic control.

Excitation‐contraction (E‐C) coupling refers to the linking of the action potential of a cardiac cell and the contraction of a muscle fibre; Ca
2+
cycling is a critical component of E‐C coupling.

Cardiac morphology and circulation patterns vary across vertebrate groups; mammals, birds and crocodiles have a double circulation while water‐breathing fishes have a single circulation.

Arterioles control blood flow to local capillary beds in the peripheral circulation via changes in arteriole diameter

Fischerella
, probably named for B. Fischer, botanical bacteriologist, 1852–1915.

Cyanobacteria / Subsection V / Incertae Sedis / Fischerella
Multicellular, with uniseriate true branches (secondary trichomes) that arise from a primary trichome (main axis) and which are composed of cells that are generally longer than broad (particularly those distal from the base). Mature trichomes do not fragment. The primary trichome is also mainly uniseriate but may become multiseriate in part as a consequence of cell divisions in more than one plane. Cells in multiseriate regions become enlarged and are often semispherical in shape, and the axis is seldom more than 2–3 cells in thickness. The older cells of a primary trichome may become separated from each other by extracellular material and may act as akinetes. Most of the widened cells of the primary trichome, however, display a true filamentous nature, with only a peptidoglycan septum separating cells. Active dispersal is by means of a motile hormogonium. The main axis of a new primary trichome forms when hormogonium motility ceases, cells enlarge, and cell divisions that are parallel or diagonal (oblique) to the long axis commence; some of the resulting cells elongate to form secondary trichomes. Fix nitrogen with lateral, terminal, or intercalary heterocysts (= heterocytes) that may differentiate on both primary and secondary trichomes.

Optically Controlled Latching and Launching in Soft Actuators
Authors: Guo Hongshuang , Priimagi Arri , Zeng Hao 
Published: December 2021

AbstractSnapping is an abrupt reaction, in which mechanical instability allows the structure to rapidly switch from one stabilized form to another. Snapping is attained through a sudden release of prestored elastic energy. It is perfected by natural species to enhance their preying, locomotion, and reproduction abilities. Recent developments in responsive materials research has allowed the realization of bioinspired snappers and rapidly moving soft robots triggered by external stimuli. However, it remains a grand challenge to reversibly and accurately control the snapping dynamics in terms of, e.g., onset timing and speed of motion. Here, a facile method to obtain light‐fueled snapping‐like launching with precise control over the elastic energy released and the onset timing is reported. The elastic energy is prestored in a light‐responsive liquid crystal elastomer actuator, and the launching event is dictated by releasing the energy through a photothermally induced crystal‐to‐liquid transition of a liquid‐crystalline adhesive latch. The method provides manual control over the amount of prestored energy, motion speed upon multiple launching events, and enables demonstrations such as jumping and catapult motions in soft robots and concerted motions of multiple launchers. The results provide a practical solution for controlled fast motions in soft small‐scale robotics.
Confinement Effects in Individual Carbon Encapsulated Nonprecious Metal‐Based Electrocatalysts

Published: December 2021

AbstractThe evolution of cost‐effective and reserve‐rich nonprecious metals (NPMs) to replace precious metal electrocatalysts is of significant interest in modern electrocatalysis. The confinement effects in NPM‐based nanoparticles encapsulated in carbon nanoshells have been considered as an emerging and efficient way to special types of electrocatalysts which facilitate electrocatalytic activity and stability, even under rigorous conditions. This review focuses on the unique individual carbon encapsulation for high‐performance design of NPM‐based electrocatalysts, outlining all confinement synthesis methods, mechanistic studies on confinement effects, and the emerging practical reactions. It begins first introducing the synthetic methods for NPM‐based core@carbon shell electrocatalysts, and then follows clarification of the relationship between the fundamental confinement effects and the performance improvement of carbon shell encapsulating NPM‐based electrocatalysts. Further and detailed discussions on the alloying effect, doping effect, and heterojunction effect of the NPM‐based core to alter the electronic situation which affects the electrocatalytic performance are subsequently provided. Finally, the review provides a perspective on challenges and opportunities in future research with respect to both in‐depth theoretical research and potential design concept of such NPM‐based core@carbon shell electrocatalysts.
Mimicking Native Heart Tissue Physiology and Pathology in Silk Fibroin Constructs through a Perfusion‐Based Dynamic Mechanical Stimulation Microdevice

Published: December 2021

AbstractIn vitro cardiomyocyte (CM) maturation is an imperative step to replicate native heart tissue‐like structures as cardiac tissue grafts or as drug screening platforms. CMs are known to interpret biophysical cues such as stiffness, topography, external mechanical stimulation or dynamic perfusion load through mechanotransduction and change their behavior, organization, and maturation. In this regard, a silk‐based cardiac tissue (CT) coupled with a dynamic perfusion‐based mechanical stimulation platform (DMM) for achieving maturation and functionality in vitro is tried to be delivered. Silk fibroin (SF) is used to fabricate lamellar scaffolds to provide native tissue‐like anisotropic architecture and is found to be nonimmunogenic and biocompatible allowing cardiomyocyte attachment and growth in vitro. Further, the scaffolds display excellent mechanical properties by their ability to undergo cyclic compressions without any deformation when places in the DMM. Gradient compression strains (5% to 20%), mimicking the native physiological and pathological conditions, are applied to the cardiomyocyte culture seeded on lamellar silk scaffolds in the DMM. A strain‐dependent difference in cardiomyocyte maturation, gene expression, sarcomere elongation, and extracellular matrix formation is observed. These silk‐based CTs matured in the DMM can open up several avenues toward the development of host‐specific grafts and in vitro models for drug screening.
