Frantz Fanon's Political Thought on Tabula Rasa
Authors: Ndayisenga Zenon
Published: August 2024

More than 60 years after his death, Frantz Fanon's decolonial political thought on the concept of tabula rasa remains influential, unique, and relevant. It is highly sought after by colonized subjects who continue to confront the ongoing project of colonialism. This chapter aims to examine Fanon's reasoning on tabula rasa, defined as a new beginning from a zero point. Fanon's decolonial political thought on tabula rasa differentiates two forms of decolonization: 'pseudo-decolonization' and 'genuine decolonization.' Pseudo-decolonization is described as false, superficial, or symbolic, whereas genuine decolonization is real, authentic, and veritable. In Fanon's political imagination, colonized subjects are urged to seek genuine decolonization, which, he argues, emerges from an inevitable and violent struggle between the colonizers and the colonized. The absence of such a profound and transformative struggle—tabula rasa—means that the colonized remain subjugated and only superficially decolonized. Fanon's mastery of the concept of tabula rasa allows for a clear differentiation between pseudo-decolonization and genuine decolonization, emphasizing the necessity of a fundamental and radical break from colonial structures.

Authors: Rodrigues Wardzinski Isabela , Tamara Tuono Angélica , Borin João Paulo , Padovani Carlos Roberto
Published: August 2024

Os grandes saltos são passos que exigem potência muscular e coordenação motora. Visto que há uma escassez na literatura sobre o aprendizado e treinamento destes passos, o objetivo deste estudo foi verificar o efeito de 12 semanas de aulas de ballet clássico com o exercício de grand allegro sobre a potência de membros inferiores em bailarinas amadoras. Participaram sete bailarinas, com 11,33±1,02 anos de idade, que cursavam o Grade 3 da Royal Academy of Dance. Foram realizados cálculos de Pico de Velocidade de Crescimento, testes de salto vertical e avaliação técnica do grand allegro em quatro momentos durante 12 semanas. Os planos de aula, Percepção Subjetiva de Esforço e Qualidade Total de Recuperação de cada aula foram analisadas. Os principais resultados apontam bailarinas pré-púberes, cuja potência muscular e técnica do exercício de grand allegro apresentaram melhora (p<0,05). A carga semanal e quantidade de saltos e de exercícios executados variaram durante o período, enquanto que a Qualidade Total de Recuperação se mostrou estável. Os dados obtidos apontam para as variações da carga de trabalho nas aulas de ballet somadas à fase sensível do desenvolvimento e coordenação motora como os responsáveis pela evolução na potência muscular e na qualidade técnica.
Practical Improvement of Noncontact Production Monitoring of Doping in SiC Wafers with Extended Epilayer Defects
Authors: Savtchouk Alexandre , Wilson Marshall , Schrayer Bret , Gutierrez Lilliana , Almeida Carlos , Lagowski Jacek
Published: August 2024

We discuss two defect related practical improvements in the corona noncontact CV metrology, (CnCV) for SiC. The improvements are introduced in response to requests from industrial tool users. The first improvement quantifies mapping of electrically active defects with the QUAD technique (Quality, Uniformity, and Defects). It provides the capability of user selectable die grids directly comparable with Near UV-PL and optical defect mapping. This shall enhance understanding of the device killer defects and help to correlate epilayer defects and device yield. The second improvement introduces auto-remeasurement of outliers appearing in doping measurements on defective sites. This procedure is analogous to that used in the Hg probe technique and it provides a means for correcting defect related distortions in SPC doping monitoring charts.
Macro Step Bunching/Debunching Engineering on 4° off 4H-SiC (0001) to Control the BPD-TED Conversion Ratio by Dynamic AGE-Ing®
Authors: Dojima Daichi , Tayake Kaito , Shigematsu Koki , Toda Kohei , Kaneko Tadaaki
Published: August 2024

This paper presents an investigation into the surface morphology control of 4H-SiC (0001) wafers cut to 4º off during thermal processing, aiming to suppress the propagation of basal plane dislocations (BPD) into the epitaxial growth layer. Developing methods for debunching rough surfaces with macro step bunching (MSB) using thermal processes removes many of the limitations of the conventional epitaxial growth process. This study presents a surface morphology control method that includes debunching of steps by thermal sublimation etching/growth using the Dynamic AGE-ing® (DA) method. By controlling the surface morphology before and after growth using this method, the dependence of the BPD-threading edge dislocation (TED) conversion ratio on surface morphology was systematically revealed. By selecting the optimal pre- and post-growth surface morphology, a 100 % BPD-TED conversion ratio was obtained for the 10 mm × 25 mm area. It was indicated that an innovative and stable surface morphology control technique using the DA sublimation process could solve numerous technological challenges in various fields.

Published: August 2024

An essential silicon carbide (SiC) manufacturing procedure for eliminating bipolar degradation in a SiC device is the detection of the basal plane dislocation (BPD) causing the phenomenon. In this work, we employed the mirror electron microscope (MEM) technique, which has higher resolution than photoluminescence. The MEM provided results for the detection of short BPDs without conversion to threading edge dislocation at the epi/sub interface. In addition, a considerable number of short BPDs were observed in the epilayer grown with the improved method, and the conversion ratio around the buffer layer could be derived.

Published: August 2024

Dislocation behaviors after post-growth thermal treatment were investigated by X-ray topography and KOH etching. Generation of prismatic dislocations were observed in X-ray topography, and density of basal plane dislocations (BPDs) increases with annealing temperature and radial temperature gradient. Distribution of newly generated BPDs in the wafer after thermal treatment is correlated to the resolved shear stress arising from radial temperature gradient.

Authors: Kondo Ren , Zeng Hong Yu , Sometani Mitsuru , Hirai Hirohisa , Watanabe Heiji , Umeda Takahide
Published: August 2024

We performed electron-spin-resonance (ESR) and electrically-detected-magnetic-resonance (EDMR) spectroscopy on 4H-SiC(1120)/SiO2 interface defects to study differences between polar-face and non-polar-face 4H-SiC MOS interfaces. We found that in the non-polar-face MOS system, interface defects prefer to form spin-less states of doubly-occupied states and/or empty states, probably due to charge transfer between Si and C atoms at the interfaces.

Published: August 2024

Numerous learning platforms and teaching methods have emerged in recent years. Identifying effective approaches is crucial for enhancing the productivity of education. This study aimed to determine the most effective learning tactics for small face-to-face management classes in tertiary education, based on students' cognitive and physiological behavior. Eight management students with varying academic backgrounds were selected through purposive sampling for the experiment which consists of active and passive learning sessions. The lecture served as the passive learning session. Problem-Based Learning (PBL) activities were conducted both individually and in groups, with another group activity following the lecture, representing the active learning sessions. Brain activity was measured using electroencephalogram (EEG) to identify Beta (β) waves. Physiological data was collected using a Galvanic Skin Response (GSR) sensor to measure sweat gland activity. Additionally, fluctuation in heart rate variation was captured through Electrocardiogram (ECG) signals. Exploratory data analysis was employed to analyse the bio-signal data. The group activity after the lecture resulted in the highest levels of cognitive and physiological engagement among participants. While students performed better in active learning sessions overall, individual activities were less effective compared to group-based activities. This study suggests that even though passive learning, like lectures, may have some value, a combination of passive and active learning strategies may yield the most productive learning environment for small group management courses in tertiary education.
Strength Evaluation of a Sliding Helicopter Fairing/Door Subject To Load and Impact Velocity Interaction
Authors:   Airbus Helicopters, Dayan David , Vagnot Alice
Published: August 2024

This paper describes a multidisciplinary strength study of a helicopter sliding fairing/door submitted to dynamic loads coming from impact velocity. Those loads result both from opening/closing procedure before or during flight and from handling manoeuvres. They are typically not considered in helicopter regulations and might be more critical than the aerodynamic load cases required for strength substantiation and helicopter certification. These loads caused indeed incidents in service and were thus deeply analyzed. This paper intends to describe:
• The technical approach used to determine those impact loads depending on the surrounding stiffness, friction/stroke on sliding mechanism and impact velocity.
• The dedicated means to perform static, dynamic and fatigue substantiation of sliding parts considering these loads (based on finite element model and laboratory test analysis).
• The importance of fractography analysis to understand failure modes of parts submitted to aerodynamic and impact loads.
In conclusion, general concepts of design recommendations following this study are presented.
Numerical Evaluation of Gust Loads on Tiltrotor
Authors:   Politecnico di Milano, Rigo Alberto ,   Leonardo Helicopters Division, Favale Marco , Quaranta Giuseppe , Trezzini Alberto
Published: August 2024

In aircraft design, the loads induced by atmospheric gust encounters are often critical for airframe structural sizing. Consequently, it is extremely important to develop methods that can predict these loads accurately. Current certification regulations include precise requirements concerning the determination of atmospheric loads. In particular, they require that such loads are calculated considering the aircraft dynamic response - including the effects of elastic deformations - to discrete gusts and continuous turbulence. In comparison to classical fixed-wing turboprops, tiltrotors often require a higher modeling complexity, because the unsteady forces generated by the rotors cannot be neglected. The paper presents a numerical tool, denominated MASST, specifically developed to build models that join a detailed FE model of the aircraft, made of different type of elements (e.g. beams, plates, solids, etc.), with a model for steady and unsteady aerodynamic forces, as well as with accurate models of rotors, servo-actuators and the Flight Control System. MASST, combined with the NASTRAN Monitor Points, can provide a high accuracy evaluation of the dynamic loads in any given section of the airframe. The methodology presented is applied and validated on the AW609 airframe dynamic FE model. In particular, different modeling options are compared to identify what is the best approach for the identification of gust loads for this peculiar aircraft configuration.

Published: August 2024

Major challenges of high quality requirements are associated with internal statistical variability, i.e., too severe gap between "as-designed" vs. "as-built" composite micro-structures. Therefore, the objective of this work is development of general physics-based methodology to correlate structural performance of RCS with inevitable variability of internal designs and demonstrate it on examples of representative composite sub-elements. Generated results can be used to provide guidance for simplifications and relaxation of existing quality requirements with obvious cost and availability improvement. Demonstration of implementation is shown on quantification of damage initiation in laminated structures under conditions of tension and bending.
Magnetic Gearing Research at NASA
Authors:   NASA Glenn Research Center, Asnani Vivake , Scheidler Justin , Tallerico Thomas
Published: August 2024

Magnetic gearing is an alternative to mechanical gearing, where torque is transferred through magnetic force as opposed to contact force. The technology has the potential to be used in aircraft applications, without the lubrication, noise, and maintenance issues that can exist with mechanical gearing. Initial design and prototype development work was done at NASA to create a foundational understanding of the technology and the factors that influence its specific torque. The specific torque achieved through design optimization was found to be less than that of high-torque mechanical aircraft transmissions, but may be comparable to that of lower torque mechanical transmissions for electrified vertical takeoff and landing aircraft. The lessons learned from NASA's initial technology development and the direction of NASA's future work in field are discussed.
Substantiation by Analysis for Fatigue Tolerance in Bell 525 Metallic Components
Authors:   Bell, Savage Stephen ,   Bell Textron India, Mukherjee Siddhartha , Green Nathan
Published: August 2024

The Bell 525 main rotor Pylon Bipod Mount is a flight critical structural component that must meet the fatigue tolerance requirements of §29.571. The complex flight load environment of the Pylon Bipod Mount involves coupling the rotor loads to the fuselage through interactions that factor roof beam displacement and the unique stress state induced by the elastomeric inner member of the Bipod. Simulating the full flight load structural response of the Bipod in a physical component test is not only extremely time consuming but also runs the risk of being inaccurate. As an alternative, an experimentally correlated finite element model is used to analyze the Bipod under the flight load environment. The approach incorporates the installation stress on the Bipod induced by its elastomeric component. The associated finite element models will be validated using state of the art experimental techniques of strain survey/mapping. Results from the correlated analytical models will be further evaluated per approved regulatory criteria to substantiate the Bipod's fatigue life and demonstrate fatigue tolerance per §29.571.
Cybersecurity and Risk Management Framework in Avionics
Authors:   Rockwell Collins, Marek James
Published: August 2024

It is impossible to open a newspaper, turn on a television, or visit a news website these days without being barraged with cybersecurity related news. Every domain is being attacked, penetrated, and impacted by cyber-crime and the range, complexity, and frequency of attacks is expanding daily. Across the board we face a wide range of adversaries from disgruntled employees to nation states that are bent on taking our critical systems down temporarily or permanently. Avionics systems are not immune from this and over the past several years, cybersecurity policies and the Risk Management Framework (DoD 8510.01) approach to securing US cyber systems, have been maturing and rapidly growing in adoption. However, many in the avionics community remain uninformed regarding the impacts of these new policies and initiatives to their systems nor how best to ensure they are taking a practical and efficient approach to implementing them. Gone are the days of a magic box that all of the security requirements are allocated to. Modern Cybersecurity is a systems discipline and cuts across the entire avionics suite. This paper will introduce the Risk Management Framework (RMF) and Cybersecurity and discuss what they are, how we got here, how they are related, and how they are impacting and will impact legacy and future avionics systems on tactical military aircraft. The paper will present some observations and best practices associated with application of Cybersecurity and RMF to avionics. It will also include some benefits of safety critical designs toward cyber-hardening and where safety and security are mutually exclusive. It will touch briefly on some impacts to avionics systems related to hot Cybersecurity topics such as HBSS (Host Based Security System), STIGs (Security Technical Implementation Guides), Static code analysis, DoD PKI (Department of Defense Public Key Infrastructure), electronic delivery, and insider threats. The paper will include a perspective on the development environment, the deployed systems, and deployment sites and how RMF and Cybersecurity impact both the contractor and the DoD customer related to these perspectives.

Authors: Manocchio Nicola , Ljoka Concetta , Piacentini Nicolò , Sorge Roberto , Vita Giulia , Foti Calogero
Published: August 2024

Osteoarthritis (OA) is a disabling disease that causes pain and functional limitation. OA symptoms can be treated with intra-articular injections of anti-inflammatory, viscosupplementary, or viscoinductive products. Non-responders to these approaches have limited options, often surgical (e.g. knee replacement). This retrospective study aims to evaluate the efficacy of a single injection of Carboxymethyl-Chitosan for advanced (Kellgren-Lawrence ≥3) and symptomatic knee OA in non-responders to hyaluronic acid. We enrolled 10 patients (5 female, 5 male). Treatment efficacy was assessed through the Visual Analogue Scale (VAS, pain) and the Knee Injury and Osteoarthritis Outcome Score (KOOS, knee function). Data are acquired from rating scales were administered at the time of injection (T0), one month (T1), three months (T2), and six months (T3) after treatment as for clinical practice. Results showed a significant improvement in pain and function at T1, with a subsequent gradual resumption of symptoms. In conclusion, the treatment showed a better outcome in the short term (i.e. up to 1 month after treatment); however, raw values of VAS and KOOS did not return to baseline levels showing a maintenance of improvement albeit not statistically significant.
Do all traumatic hemothorax require a tube thoracostomy: A retrospective review
Authors: George Paul Yohan , Purushothaman Vijayan , Sathyakumar Kirthi , Kumar Vignesh
Published: August 2024

Background:

Blunt thoracic trauma accounts for a majority of trauma-related admissions. The Eastern Association for the Surgery of Trauma guidelines recommend placement of a tube thoracostomy for all patients with a hemothorax. Our study was conducted to look at those managed without an intercostal drain (ICD) and the factors that could predict a failure in conservative management.

Materials and Methods:

A retrospective study was conducted from January 2020 to June 2022 at a level-one trauma center in South India to account for patients who required a tube thoracostomy after planned expectant management for hemothorax. All adult patients above 16 years, with traumatic hemothorax were included. Those who had ICD inserted in the emergency department before computed tomography (CT) and those who did not have a CT Thorax were excluded. A retrospective review of patient records was conducted and analyzed using Stata (ver. 16).

Results:

Eighty-eight patients were included in the study, of whom 11 patients required a tube thoracostomy after an initial trial of conservative/expectant management (i.e., not inserting an ICD). The most common reason for failure was an increase in the size of the hemothorax. Among all the predictors we looked at, only a systolic blood pressure of <90 mm Hg on presentation was statistically significant for predicting failure of expectant management.

Conclusion:

Our study suggests not all patients with a traumatic hemothorax require a tube thoracostomy and can be managed expectantly provided close monitoring is possible. An increase in the size of the hemothorax was the main indication for a tube thoracostomy.

Toxic effects of multi-walled carbon nanotubes and ZnO nanoparticle exposure on pathology and apoptosis on the liver of Cyprinus carpio
Authors: Wang Yashuai , Niu Xuehan , Huang Yong , Ren Hongtao , Chen Jiayong , Xu Ruiyi , Gao Xiaochan
Published: August 2024

ZnO nanoparticles (ZnONPs) and carbon nanotubes (CNTs) are frequently used nanoparticles with unique features. Aquatic organisms are exposed to a combination of contaminants in natural water systems, so the combination effect of two or more nanomaterials has caused much concern. In this study, the toxicity to the liver of common carp was explored under four weeks of exposure to single ZnONPs or in combination with multi-walled CNTs (MWCNTs). The results demonstrated that ZnONPs induced pathological changes and apoptosis in the liver. In combination, decreased pathological changes were observed in the LSC-ZnONPs group (50 mg L-1 ZnONPs and 0.25 mg L-1 MWCNTs) at the microscopic level and ultrastructural level, and increased pathological changes in the HSC-ZnONPs group (50 mg L-1 ZnONPs and 2.5 mg L-1 MWCNTs). A 52% reduction in the percentage of TUNEL-positive nuclei in the LSC-ZnONPs group and a 33% increase in the HSC-ZnONPs group were observed compared to the ZnONPs group. The mRNA expression of apoptosis-related genes, including caspase3, BAX, and XBP1, were significantly up-regulated in the exposure groups, confirming the occurrence of apoptosis. Significantly decreased caspase 3 and BAX mRNA levels in the co-exposure groups were detected compared to the ZnONPs group. Nevertheless, the XBP1 mRNA level was significantly upregulated in the LSC-ZnONPs group, but downregulated in the HSC-ZnONPs group, indicating multiple signal pathways involved in the apoptosis. In conclusion, a low concentration of MWCNTs (0.25 mg L-1) decreased the toxic effect of ZnONPs on common carp, but a high concentration of MWCNTs (2.5 mg L-1) enhanced it. This study will contribute to developing future risk assessment and management strategies for nanomaterials.
Entre responsabilização e culpabilização de mulheres em casos de violência doméstica: um relato de experiência a partir do Projeto Núcleo Maria da Penha - NUMAPE
Authors: Santos Kátia Alexsandra dos , Santos Fernanda Sabei de Souza
Published: August 2024

O presente trabalho se trata de um relato de experiência que visa apresentar como se dá o processo de responsabilização de mulheres em situação de violência no decorrer dos atendimentos psicológicos e jurídicos ofertados no Núcleo Maria da Penha (NUMAPE),  um projeto de extensão vinculado ao programa Universidade Sem Fronteiras (USF/SETI-PR). Fazendo uso do referencial teórico de Saffioti (2004/2015), refletimos sobre o fenômeno da violência doméstica e suas bases em uma estrutura patriarcal e capitalista,  a partir de recortes de casos atendidos no referido projeto de extensão. As intervenções têm caminhado no sentido de diferenciar responsabilização de culpabilização, colocando as mulheres como ativas no processo de enfrentamento à violência, sem deixar de reconhecer seu lugar na relação histórica constituída entre homens e mulheres. Por fim, o texto discute acerca das dificuldades dessa diferenciação na prática e os reflexos disso na atuação das profissionais e estagiárias do projeto.
Uma transição inacabada: as caravanas da anistia no Brasil
Authors: Hoffmann Fábio
Published: August 2024

O presente artigo se vale das Caravanas da Anistia como objeto de estudo para explorar alguns dos principais aspectos da transição democrática brasileira face às suas as tentativas de confrontar o seu passado de violações recorrentes aos direitos humanos e crimes de lesa humanidade. A análise clarifica três momentos da jovem democracia no Brasil: a conciliação que não existiu, a reparação que não se completou e o futuro incerto quanto à garantia de não repetição por parte do Estado das violações aos direitos humanos. A não punição de perpetradores de violações, a ausência da garantia efetiva do direito à verdade e a incompletude das reparações materiais e simbólicas, trouxeram como resultado o ressurgimento da cultura política autoritária bojada de um revisionismo saudosista do período da Ditadura Militar, principalmente diante da realidade pós-factual que encontra acolhimento em parte da sociedade.
Migrações, Subalternidade: o processo contraditório entre dominação e resistências
Authors: Toledo Alex Fabiano de , Lemes João Ricardo
Published: August 2024

A problematização que vincula as migrações internacionais e a proteção social têm ocupado destaque no atual estágio de produção e reprodução da vida social. Sinaliza para a compreensão dos processos de subordinação, dominação, poder e de exploração inerentes à dinâmica do capital, que forja e atinge, exponencialmente, a população migrante. Ao mesmo tempo, remete a um esforço teórico-analítico que se expressa em apreender o trato que, nas políticas sociais, vem sendo conferido à realidade migratória e o direito à proteção social. Partindo do referencial teórico de Antônio Gramsci, este estudo tem como objetivo refletir sobre a subalternidade como um processo contraditório entre a resistência e a subordinação, no âmbito dos processos migratórios contemporâneos. Dentre os resultados destaca-se que as propostas neoliberais em relação ao papel do Estado na esfera da proteção social à população migrante são reducionistas, seletivas, focalizadas e esvaziadas do seu caráter de política de direitos.

Published: August 2024

Port congestion in Nigeria significantly hampers operational efficiency and economic growth, leading to delays and operational stagnation. This study aims to identify the primary problems contributing to port congestion, including poor management, inadequate infrastructure, and bureaucratic delays. The study investigates the impacts of decongesting seaports through the development of Inland Container Depots (ICDs) on economic growth, port management, government policy, and transportation systems in Nigeria, focusing on the Kaduna and Jos dry ports. Utilizing a mixed-method approach, the research involved qualitative interviews with port stakeholders and quantitative surveys among dry port users and service providers. Qualitative findings reveal that developing ICDs in Kaduna and Jos has significantly contributed to economic development through job creation, revenue generation, and reduced shipping costs. However, port congestion remains a challenge due to poor management, inadequate infrastructure, and bureaucratic delays. Specifically, the Kaduna port faces issues such as poor planning, handling, and storage of cargo, while Jos is plagued by traffic bottlenecks, strikes, and inadequate staffing. Quantitative analysis confirmed these findings, showing significant correlations between seaport decongestion and economic development (r sig. value of 0.00), port management and port congestion (r sig. value of 0.00), government policy and inland port development (r sig. value of 0.00), and transportation systems and inland port development (r sig. value of 0.00). The correlation analysis indicated a low positive relationship between port management and economic development, and a moderate positive relationship with government policies. In conclusion, the establishment of ICDs in Kaduna and Jos plays a crucial role in alleviating port congestion, fostering economic growth, and improving the overall efficiency of Nigeria’s logistics network. Government policies have been identified as barriers to ICD development, highlighting the need for supportive regulations and infrastructure investment. Effective port management, supportive government policies, and robust transportation infrastructure are essential for maximizing the benefits of ICDs and enhancing Nigeria’s trade competitiveness. ICDs are proposed as a viable solution to these issues, functioning as inland terminals directly linked to seaports and thereby enhancing the overall efficiency of the supply chain network.

Cooperative instructional method is heuristic and mainly learner-centred involving student team learning while Conventional instructional method is expository and teacher-centred. The objective of the study was to investigate the difference in Geometry performance between students taught using the Cooperative instructional method and those taught using the Conventional instructional method. A quasi-experimental design was used. The target population was students and teachers from secondary schools in Meru County, Kenya. Purposive sampling was used to arrive at a sample of six (6) secondary schools, two (2) for boys only, two (2) for girls only, and two (2) co-educational schools. The sampled schools were grouped into two, a control group and an experimental group. The data collection instruments were pre- and post- Geometry Achievement Tests (GAT). To ensure validity of the instruments senior examiners and Mathematics educators in the County reviewed the pre- and post-tests. Quantitative data was analysed using Version 27 of the Statistical Package for Social Science (SPSS) thereby generating graphs, analysis Tables and frequency charts for inferential and descriptive statistical analysis. The results showed that there is a difference in Geometry performance between students taught using the Cooperative instructional method and those taught using the Conventional instructional method. The hypothesis was examined with a significance level set at α = .05. The mean score for the control group was 26.27 and a standard deviation of 10.926 which differed significantly from those in the experimental group, which had a mean score of 74.02 and a standard deviation of 12.495. The results indicated a significant statistical difference (t (195) = -28.493, p < .05) between the two groups. From the results it is concluded that using the Cooperative instruction method leads to improved students’ performance in Geometry. It is suggested that secondary schools Mathematics teachers should use Cooperative instructional method in secondary schools as a way of enhancing students’ performance in Geometry.
