A Form-Finding Method for Branching Structures Based on Dynamic Relaxation

Branching structure is often used as a supporting structure of the grid shell due to its geometrical and force-transferring features, and the rationality of its shape is very important. The “physical” and “numerical” hanging models can be used for the joint form-finding of the branching structure and free-form grid shell. However, slack elements may exist in the equilibrium model which corresponds to the inefficient members in the form-found branching structure. To solve this problem, a form-finding method of branching structure based on dynamic relaxation is proposed in this study. The proposed method clusters the elements of the branching model and equalizes the axial forces of the elements in the same cluster, in other words, there are no slack elements in the equilibrium branching model. This method overcomes the defect that the equilibrium branching model may have slack elements and needs many manual adjustments during the procedure of determining the rational shape of a branching structure, and effectively prevents the inefficient members existing in the form-found structure. Numerical examples are provided to demonstrate the characteristics of the proposed method and its effectiveness is verified as well.

Cooperation between the EU and China: A post-liberal governmentality approach

The European Union's partnership with China has received significant academic attention. Experts have focused on both parties’ economic and political objectives and have made efforts to grasp the dynamics of the institutionalisation of EU-China cooperation. However, little has been said about how this collaboration affects the lives of citizens, especially in China. Adopting a Foucauldian epistemology, this article's key contention is that EU-China cooperation imposes a joint form of post-liberal governmental power on the Chinese population, which socially constructs empowered but not liberal political subjectivities for Chinese citizens. The article first reviews Foucault's approach to governmentality. It then explores Sino-EUropean collaboration after 2013, when the two partners established the ‘EU-China 2020 Strategic Agenda for Cooperation’. We illustrate how the institutionalisation of the partnership has been consistent with a governmentalised political rationality, and how policy implementation has allowed a post-liberal form of governmental power to flow from both EU and Chinese policymakers towards the Chinese population, triggering processes of political subjectivisation.

Anatomical Joint Form Variation in Sacroiliac Joint Disease: Current Concepts and New Perspectives

Purpose of Review The aim of this article is to further the understanding of anatomical variation of the sacroiliac joint (SIJ) within the rheumatological community and point out promising fields of research in the interplay of SIJ anatomy and joint disease. Recent Findings Mechanical strain has long been implicated in onset and progression of axial spondyloarthritis (axSpA). Recent investigations found changes in the pattern of degenerative lesions of the SIJ in the normal population in patients with atypical joint forms. Furthermore, atypical SIJ forms are more prevalent in patients with axial spondyloarthritis and mechanical SIJ disease. Summary Mechanical stress from anatomical joint form variation may have an impact on development and progression of axSpA. Furthermore, mechanically induced bone marrow edema may act as an axSpA mimic on MRI and needs to be more accurately classified.

Ma‘ānī Asmā’ Allāh al-Ḥusnā Ḥāl al-Iqtirān wa Ḥāl al-Ifrāḍ fī Khawātīm Ba‘ḍi Āyāt al-Qur’ān: Dirāsah Waṣfiyyah Taṭbiqiyyah

The Quran is the fundamental source by which a person knows his Creator through the knowledge of the names of Allah and His attributes, which represents the subject of the unification of Allah and affects the faith of a Muslim, train his soul and conscience and refine his behavior. Thorough examination of the names and attributes of Allah in the Qur’an reveals that both the names and attributes can be found in either of the two instances: in a joint form or in isolation to show that in both cases they carry different meanings, so the study aimed at explaining the names and attributes of Allah, in both of the two instances in some verses of the Quran. The study followed the descriptive and empirical methods. The paper found that the names and attributes of Allah are tawqifiyyah,(Divine), there is no room for personal reasoning, and that the names and attributes of Allah signify perfect and sublime qualities, It was also discovered by the study that the name of (Allah) Al-‘Azīz (The Almighty) was associated with wisdom (Hikmah), the name of (Allah) Al-Laṭīf (The Gentle) with mercy (Rahmah) and the name of Al-‘Afuw (The forgiver) with power and ability (Qudrah). Based on this, the more a person knows Allah the more he reveres Him and follow His commandments. The research finally recommends that to guard the behaviour of a Muslim society, people need to learn the meanings of names and attributes of their Creator.

Kajian Perancangan Karakter Maskot Universitas Pendidikan Mandalika

Mascot is a promotional media that is familiar in promotional media. Several companies to universities have mascots as icons that can represent higher education. UNDIKMA as a new joint-form campus has not used the media in the form of mascots for promotion. considering that NTB is a heterogeneous region with respect to ethnicity, religion, and race, so it requires a mascot as a brand ambassador for UNDIKMA. This is important because in the NTB region there is no tertiary institution that has a mascot. In the previous study, there was no study on mascot creation for universities. The purpose of this research is to design a mascot with a method approach that puts forward the target audience. While the method used is the Design Thinking Method developed by Tim Brown. Design thinking is a way to solve ambiguous and unfamiliar problems, rediscover problems in a human-centered way, brainstorm to generate multiple ideas, and take a hands-on approach. Very useful for prototyping and testing. Design thinking also includes continuous experimentation, such as sketching, prototyping, experimenting, and trying out different concepts and ideas. The target outcome of this research is to hopefully create a mascot design. In addition, it is also hoped that the output in the form of a mascot design guide line will also be successfully written. So that the application of the mascot can be correct and in accordance with the objectives expected by the designer.

Impact of age, sex, and joint form on degenerative lesions of the sacroiliac joints on CT in the normal population

Degeneration of the sacroiliac joints (SIJs) is a common finding, while its underlying cause and development remain incompletely understood. The aim of this investigation was to describe the spatial distribution of degenerative SIJ changes across age groups and to investigate for the first time their relationship to anatomical form and sex. For this IRB-approved investigation, demographic data of 818 patients without SIJ disease were retrieved from electronic patient records. High-resolution computed tomography (CT) datasets of all patients were analysed retrospectively for seven predefined age groups (ten-year increments, from < 25 to ≥ 75). A structured scoring system was applied to assess sclerosis, osteophytes, joint space alterations, and anatomical form. Chi-square tests were used to compare frequencies of degenerative lesions, and logistic regression analyses were performed to investigate associations between demographic data, anatomical form, and the presence of structural lesions. Sclerosis and osteophytes were common findings, with an overall prevalence of 45.7% and 46.8%, respectively. Female sex had an odds ratio (OR) of 0.15 (95% CI: 0.08–0.27) for the presence of ventral osteophytes and of 4.42 (95% CI: 2.77–7.04) for dorsal osteophytes. Atypical joint forms were significantly more prevalent in women with 62.1% vs. 14.1% in men (p < 0.001). Accessory joints increased the likelihood of dorsal sclerosis (OR 2.735; 95% CI 1.376–5.436) while a typical joint form decreased its likelihood (OR 0.174; 95% CI 0.104–0.293). Sex and anatomical joint form have a major impact on the development of degenerative lesions of the SIJs and their spatial distribution.

Mechanical Behavior of Friction Stir Welded AA-6061 Thick Plates in Different Heat Treatment Conditions

In this study, mechanical properties of friction stir welded Aluminum Alloy (AA) 6061 in three different heat treatment conditions i.e. Annealed (O), Artificially aged (T6) and Post Weld Heat Treated (PWHT) were compared. Plates were welded in a butt joint form. Parameters were optimized and joints were fabricated using tool rotational speed and travel speed of 500 rpm and 350 mm/min respectively. Two sets of plates were welded in O condition and out of which one was, later, subjected to post weld artificial aging treatment. Third set was welded in T6 condition. The welds were characterized by macro and microstructure analysis, microhardness measurement and mechanical testing. SEM fractography of the tensile fracture surfaces was also performed. Comparatively better mechanical properties were achieved in the plate with PWHT condition.

The effect of antiseptics on the crystallogenic properties of Pseudomonas aeruginosa

The aim of the work was to clarify the crystallogenic properties of pseudomonads under the action of an antiseptic. The material for the study was 8 strains of Ps. aeruginosa. In accordance with the purpose and objectives of the study, the work was carried out in 3 stages: assessment of the biological properties of the isolated pseudomonas strains; determination of sensitivity to disinfectants by the squares method; assessment of the crystallogenic (initiating) the activity of pseudomonads in an individual and joint form with a disinfectant. The tested antiseptic was "Desam" in the form of a standard 1% solution. Most of the analyzed strains turned out to be sensitive to the applied working concentration of the tested disinfectant and are active initiators of the crystallogenesis of sodium chloride solution. The revealed significant differences in the tesigraphic test conducted with pseudomonas strains sensitive and resistant to the studied disinfectant create prerequisites for the development of a new express method for determining the sensitivity of microorganisms to disinfectants.
