Publisher: name: Swinburne
Year: 2024

description: The performance of current sidewalls made of carbon and silicon based materials relies on the existence of a frozen electrolyte layer. The development of the Hall-Heroult cell technologies such as inert anodes and wettable cathodes, call for new sidewall materials since the frozen ledge may no longer be applicable. Nickel ferrite has been identified as a possible sidewall material, particularly in relation to its resistance to cryolite and air attack. The presentation proposes some strategies to tackle the combined corrosive action of cryolite, molten aluminium and oxygen upon sidewalls. A multi-layer approach is proposed that optimizes both the chemical and heat flux requirements of a sidewall. Issues relating to joining of materials, process control, manufacturing, maintenance and cost need to be addressed before new sidewall designs can be implemented.

description: Monocular camera sensors are vital to intelligent vehicle operation and automated driving assistance and are also heavily employed in traffic control infrastructure. Calibrating the monocular camera, though, is time-consuming and often requires significant manual intervention. In this work, we present an extrinsic camera calibration approach that automatizes the parameter estimation by utilizing semantic segmentation information from images and point clouds. Our approach relies on a coarse initial measurement of the camera pose and builds on lidar sensors mounted on a vehicle with high-precision localization to capture a point cloud of the camera environment. Afterward, a mapping between the camera and world coordinate spaces is obtained by performing a lidar-to-camera registration of the semantically segmented sensor data. We evaluate our method on simulated and real-world data to demonstrate low error measurements in the calibration results. Our approach is suitable for infrastructure sensors as well as vehicle sensors, while it does not require motion of the camera platform.

description: Operation monitoring for automation systems requires self-assessment of all data processing modules. In this work, we extend our new self-assessment method for linear Kalman filters based on subjective logic to nonlinear Kalman filtering. Furthermore, we propose novel approaches within this subjective logic-based framework to assess the overall filter performance in multi-sensor systems online, i.e., in real-time without ground truth data. The results of the proposed self-assessment method for nonlinear Kalman filtering are demonstrated through simulation studies, showing advantages compared to classical consistency measures, like the normalized innovation squared. In addition, the results of the proposed online overall filtering assessment for multi-sensor systems can even compete with consistency measures based on ground truth data, which cannot be applied in online applications.
Formation of an RNA polymerase II pre-initiation complex on an RNA promoter derived from hepatitis delta virus in vitro

description: Hepatitis delta virus (HDV) is the smallest known RNA pathogen able to infect humans. It is a subviral agent that depends on hepatitis B virus (HBV) infection. As HDV does not possess its own polymerase, the virus is believed to depend upon the host DNA-dependent RNA polymerases (RNAPs) for its transcription and replication. Although RNAPs are able to use RNA as a template, how they recognize RNA promoters is unknown. In this study, I used a 199-nts HDV RNA fragment, corresponding to the right terminal stem-loop extremity of the genomic polarity (R199G; nts 1540 to 60) as a model to investigate the recognition of an RNA promoter by RNAP II. Inhibition of the transcription reaction using an antibody specific to the C-terminal domain (CTD) of the largest subunit of RNAP II, and the direct binding of purified RNAP II to the RNA promoter confirmed the involvement of RNAP II in this process. RNA affinity chromatography established the formation of an RNAP II pre-initiation complex on R199G, and that the formed complex contains the core RNAP II subunit and the general transcription factors TFIIA, TFIIB, TFIID, TFIIE, TFIIF, TFIIH, and TFIIS. I also found that the addition of free nucleotide triphosphates (NTPs) to the RNAP II pre-initiation complex formed on R199G caused the formation of an active initiation complex. As a result of the RNAP II complex activation, a short HDV RNA transcript was transcribed from R199G, and its 5' extremity was found to be located near the expected transcription start site of HDV mRNA (i.e. 1630). I also established the direct binding of the TATA-binding protein (TBP) to the RNA promoter, and suggested that this protein might be required for RNAP II complex nucleation on the RNA promoter. My findings represents a milestone in the study of the unconventional use of an RNA promoter 2 by RNAP II, and provide a better understanding of the events leading to the formation of the RNAP II pre-initiation complex on an RNA promoter.

description: Reduced physical activity and almost unlimited availability of food are major contributors to the development of obesity. With the decline of strenuous work, energy expenditure due to spontaneous physical activity has attracted increasing attention. Our aim was to assess changes in energy expenditure, physical activity patterns and nutritional habits in obese subjects aiming at self-directed weight loss. Methods: Energy expenditure and physical activity patterns were measured with a portable armband device. Nutritional habits were assessed with a food frequency questionnaire. Results: Data on weight development, energy expenditure, physical activity patterns and nutritional habits were obtained for 105 patients over a six-month period from an initial cohort of 160 outpatients aiming at weight loss. Mean weight loss was −1.5 ± 7.0 kg (p = 0.028). Patients with weight maintenance (n = 75), with substantial weight loss (>5% body weight, n = 20) and with substantial weight gain (>5% body weight, n = 10) did not differ in regard to changes of body weight adjusted energy expenditure components (total energy expenditure: −0.2 kcal/kg/day; non-exercise activity thermogenesis: −0.3 kcal/kg/day; exercise- related activity thermogenesis (EAT): −0.2 kcal/kg/day) or patterns of physical activity (duration of EAT: −2 min/day; steps/day: −156; metabolic equivalent unchanged) measured objectively with a portable armband device. Self-reported consumption frequency of unfavorable food decreased significantly (p = 0.019) over the six-month period. Conclusions: An increase in energy expenditure or changes of physical activity patterns (objectively assessed with a portable armband device) are not employed by obese subjects to achieve self-directed weight loss. However, modified nutritional habits could be detected with the use of a food frequency questionnaire.

description: Au cours des dernieres annees, l'autonomie gouvernementale des peuples autochtones a occupe beaucoup de place dans les milieux politique et juridique. Les nations autochtones pretendent qu'elles ont le droit inherent de s'auto-gouverner et qu'il s'agit la d'un droit ancestral protege par la constitution canadienne. D'autre part, on compte de plus en plus de recours intentes contre la Couronne, au motif qu'elle a manque a son obligation de fiduciaire envers les autochtones, et on constate une receptivite accrue des tribunaux face a de telles pretentions. La presente these se veut une etude des liens qui peuvent exister entre ces deux concepts juridiques. L'interet du sujet releve de l'incompatibilite apparente qui existe entre le droit des peuples autochtones de s'auto-gouverner et l'obligation qu'a la Couronne, a titre de fiduciaire, d'assumer la responsabilite de leur bien-etre et la protection de leurs interets.

description: In this work, the stability of ether-based electrolytes for Li-S batteries is investigated with particular regard to the effect of dissolved oxygen. Specifically, the performance of two different electrolyte solvents, i.e., 1,2-dimethoxyethane and its mixture with 1,3-dioxolane (DME:DOL, 1:1 v/v), is characterized in cells assembled in dry air environment, which would substantially lower production costs with respect to inert atmosphere (Ar). Although stability of all the components would suggest that Li-S batteries built in both the environments should behave similarly, it is found that cells containing the DME:DOL-based electrolyte are rather unstable in the presence of O2 in contrast to those employing DME-based electrolyte, which show a relatively good performance. The different sensitivity toward O2 of these electrolytes is associated to the ring-opening reaction of DOL, which happens to a greater extent when O2 is present, but occurs also in its absence. Based on these results a mechanism for electrolyte degradation in Li-S cells, and its reaction with dissolved polysulfides is proposed, which rationally explain for the first time the behavior already reported in literature for these kind of batteries. These findings are also relevant to the field of Li-O2 batteries, where these ether-based electrolytes are also used.

description: Objective: Sports clubs provide an opportunity to tackle childhood obesity rates through targeted interventions. Our study aimed to investigate if coaches providing healthy snacks to participants before junior netball sessions at five clubs in Melbourne, Australia, increased consumption of healthy foods and influenced coach perceptions of participants' attention/participation levels. Methods: Coaches provided healthy snacks to participants before each netball session for one school term. Children's food consumption was observed at one session before, during and after the intervention. Parents attending the observed session completed pre- and post-intervention questionnaires. Coaches rated participants' attention/participation at the observed sessions before and during the intervention, and completed a questionnaire post-intervention. Results: Baseline: Ice cream and cake were the most frequently consumed snacks. During intervention: Fruit, cheese and crackers and vegetables were the most frequently consumed snacks. Coaches ratings of participants' attention/participation increased significantly (baseline: 6.4 ± 0.17, intervention: 7.5 ± 0.36; p=0.02) where the same coach undertook ratings at both time points. Conclusions: Coaches providing healthy snacks before sessions at sports clubs increased consumption of nutrient-dense foods at the session, and may have positively affected participants' attention/participation. Implications for public health: This study highlights how a simple intervention could improve the diet of Australian children.

Diagnosis
The genus Myrmelachista is recognised by its five-toothed mandible, 9 or 10 segmented antennae, with a 3 or 4 segmented antennal club and a wedge-shaped, erect, prominent and exposed petiole (Fig. 4).
Distribution
Information on this species is scarce. In Colombia, it was known to be present, but without specific locality data (Fernández et al. 2019). It is reported here for the first time in the Department of Caquetá, in the Colombian Amazon Region. In the Neotropical Region, the species has also been recorded in Ecuador, Peru, Guyana and Venezuela (Kusnezov 1953, Frederickson 2005 a, Salazar et al. 2015).
Biology
M. schumanni is recognised for its specific relationship with some plant species, forming the so-called Devil's gardens. This mutualistic interaction has been the subject of several studies (Frederickson et al. 2005, Frederickson 2005 a, Frederickson 2005 b, Frederickson and Gordon 2007), demonstrating the impact of this relationship in tropical rainforests. The collected specimen was sampled by leaf-litter sifting in a preserved area from a cloud forest. The presence of this species in leaf litter can be incidental due to the species' foraging behaviour on vegetation, which can result in its falling to the forest floor.

"Maybe home is an uneasy place": Dionne Brand's uneasy home-spaces

description: When contemporary Caribbean-Canadian writer Dionne Brand encounters home, she is confronted by social norms - domestic and national - that may exclude her based on race, gender, sexuality and birthplace, or that may include her on the conditional denial of any one of these identifications. Reading her memoir and three novels, this study examines Brand's conceptualization of home and her attempts to uncover its failings, dismantle its borders, and ultimately refigure the concept of home as what I term Brand's uneasy homespaces - sites where provisional reterritorializations sign and enable agency, open the possibility of connection through negotiation, and retain uneasiness as a reminder of necessary provisionality. Through prolonged attention to the difference between the theoretically empowering and the materially destructive, Brand resists utopian fantasies of cosmopolitan global citizenship and the metaphorization of homelessness, while also countering, in her later work, easy dismissals of the nation-state by presenting a community that gains agency through identification with the city and nation even as it actively critiques the state.

description: Objective: To evaluate compliance with diabetes screening guidelines for cardiovascular disease prevention in Rheumatoid Arthritis (RA) compared to the general population. Methods: We conducted the first longitudinal study of a population-based RA cohort including all prevalent RA cases in British Columbia between 1996 and 2006, followed-up until 2010, with matched general population comparators. Using administrative data, we measured compliance with general population guidelines, i.e. testing plasma glucose (PG) at least once every three years after age 45, after excluding individuals with previous diabetes. Follow-up was divided into three-year eligibility periods. Compliance was measured as the proportion of periods with ≥1 PG test performed. OR (95% CI) of compliance in RA (vs. general population) was calculated using GEE models, adjusting for age and sex. Mean compliance rate per patient was also calculated and compared using Mann-Whitney U test. Results: Analysis included 22,624 individuals with RA, contributing 48,724 three-year eligibility periods; and 22,579general population, contributing 51,081 three-year eligibility periods. PG was measured in 72.3% (SD=37%) of the eligible time periods in the RA sample and in 70.4% (SD=38%) for the general population (OR=1.05 [95% CI:1.02;1.09], p<.0001). RA individuals met recommended screening guidelines in 71.4% of their eligible periods, compared to 70.6% (p<.001). Screening improved over time in RA relative to the general population. Family physicians ordered nearly all the PG tests. Conclusion: Compliance with general population guidelines for diabetes screening in RA was suboptimal, with little difference relative to the general population, despite a higher risk of cardiovascular diseases and diabetes.
Operators in the cohomology of nilpotent Lie algebras.

Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2001
Subjects: subject: Mathematics.

description: Operators in the cohomology of Lie algebras are defined, and fundamental results are proven. The central representation is shown to be useful, in particular cases, for proving the Toral Rank Conjecture (TRC), which states the logarithm of the total dimension of any nilpotent Lie algebra's cohomology space is greater than or equal to the dimension of the centre. Central representation and secondary operators are used to find hypercube-like structures in the cohomology of the free two-step nilpotent Lie algebras with two, three and four generators. Also, a theorem about the new operators acting on the cohomology of the Heisenberg Lie algebras, and how these operators interact with Poincare duality for this case, is proven.

Performance study of the leaky least mean square adaptive algorithm with delayed adjustments.
Creators: name: Laichi, Farouk.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1993
Subjects: subject: Engineering, Electronics and Electrical.

description: Adaptive filters constitute an important part of signal processing. They are widely used in many applications where signal statistics are unknown to the users. One of the most popular adaptive methods is known as the least mean-squared (LMS) algorithm. It is well known for its hardware simplicity and its cost effectiveness. However, the LMS adaptive algorithm does not operate well in non-ideal environments. Leakage in the updated equation of the LMS algorithm was proven to overcome many such problems. This algorithm is known as the leaky LMS (LLMS). The LLMS is very robust to drifting phenomena and overflow in registers; problems that occur in the digital implementation of adaptive algorithms. In many applications, an inherent delay in the feedback error path is encountered. This delay has a definite effect on the performance of the LLMS algorithm. In this thesis, we study the performance of LLMS in the presence of delay (LDLMS). This algorithm is basically the LLMS with a delay incorporated in the coefficient updated equation. A new general stability bound is derived for the LDLMS, from which bounds of convergence of LMS, LLMS, and delayed LMS(DLMS) can be obtained. Stability bounds, convergence behavior, and excess mean squared error for this new algorithm are investigated. Theoretical results are first derived and later verified by simulations. It will be shown that introducing leakage in the DLMS algorithm gives a compromise performance. Finally, examples of applications of the LDLMS algorithm are provided.

description: Giant Cell Glioblastoma (gcGBM) and Pleomorphic Xanthoastrocytoma (PXA) are rare astroglial tumors of the central nervous system. Although they share certain histomorphological and immunohistochemical features, they are characterized by different clinical behavior and prognosis. Nevertheless, few cases remain uncertain, as their histomorphological hallmarks and immunophenotypes do correspond to the typical pattern neither of gcGBM nor PXA. Therefore, in addition to the routinely used diagnostic histochemical and immunohistochemical markers like Gömöri, p53 and CD34, we analyzed if genetic variations like MGMT promoter methylation, mutations in the IDH1/2 genes, or BRAF mutations, which are actually used as diagnostic, prognostic and predictive molecular markers in anaplastic glial tumors, could be helpful in the differential diagnostic of both tumor entities. We analyzed 34 gcGBM and 20 PXA for genetic variations in the above-named genes and found distinct distributions between both groups. MGMT promoter hypermethylation was observed in 3 out of 20 PXA compared to 14 out of 34 gcGBM (15% vs. 41.2%, p-value 0.09). BRAF V600E mutations were detected in 50% of the PXA but not in any of the gcGBM (50% vs. 0%, p-value < 0.001). IDH1 R132 and IDH R172 mutations were not present in any of the PXA and gcGBM cases. Our data indicate, that in addition to the histological and immunohistochemical evaluation, investigation of MGMT promoter methylation and in particular BRAF V600E mutations represent reliable additional tools to sustain differentiation of gcGBM from PXA on a molecular basis. Based on these data specific BRAF kinase inhibitors could represent a promising agent in the therapy of PXA and their use should be emphasized.

description: We here propose the implementation of a simple and effective method to enhance the quality of basic and preclinical academic research: critical incident reporting (CIR). CIR has become a standard in clinical medicine but to our knowledge has never been implemented in the context of academic basic research. We provide a simple, free, open-source software tool for implementing a CIR system in research groups, laboratories, or large institutions (LabCIRS). LabCIRS was developed, tested, and implemented in our multidisciplinary and multiprofessional neuroscience research department. It is accepted by all members of the department, has led to the emergence of a mature error culture, and has made the laboratory a safer and more communicative environment. Initial concerns that implementation of such a measure might lead to a “surveillance culture” that would stifle scientific creativity turned out to be unfounded.

description: Background: Informal recycling refers to the street-based collection of discarded materials for reuse, resale, or return to a recycling facility for money. While qualitative research has explored experiences and perceptions of informal recycling, little is known about the scope and exposures associated with informal recycling among people who use drugs (PWUD). Methods: Using data from two prospective longitudinal cohorts of PWUD, we examined the prevalence of informal recycling and its association with social, structural and health risks, including criminal justice system involvement. Results: Between June 2010 and May 2015, of 1664 participants, 557 (33.5%) reported engaging in informal recycling during the study period. In multivariable generalised estimating equations (GEE) analyses, informal recycling was positively associated with injection drug use (Adjusted Odds Ratio (AOR)=1.43, 95% Confidence Interval (CI) 1.21–1.68), public injection (AOR=1.27, 95% CI 1.09–1.49), methamphetamine use (AOR=1.35, 95% CI 1.05–1.72), difficulty finding harm reduction equipment (AOR=1.16, 95% CI 1.02–1.32), and police interactions (AOR=1.35, 95% CI 1.18–1.55). Sub-analyses revealed PWUD engaged in informal recycling were more likely to be told to move on, ticketed, stopped for jaywalking, and directed to services by police. Conclusions: These findings suggest informal recycling as a situated practice for PWUD, with potential indications for higher-risk drug use, experiencing greater surveillance, and difficulty accessing health and addiction treatment services. This research highlights the significance of the broader risk environment and the need for health-promoting policies for socioeconomically marginalised PWUD engaged in informal recycling.

description: Nickel(II)-aryl complexes [(L2)Ni(Ar)Br] bearing either chiral phosphine ligands (L2 = RR- or SS-DIPAMP, Ar = ortho-anisyl), or a chiral aryl-group have been prepared, and their structural optical an chiroptical properties have been characterized. Enantiomeric pairs of both catalysts have been used for the asymmetric polymerization of different isocyanides (M1, M2, M3), to give well defined polyisocyanides (P1, P2, P3). Their polymerization behavior has been studied, which confirmed chain-growth polymerization in all cases. The asymmetric induction has been verified by circular dichroism spectroscopy on enantiomeric pairs of all three polymers. Helically chiral polyisocyanides have been prepared using different types of Nickel(II) precatalysts via the chain‐growth polymerization. The asymmetric induction has been verified by circular dichroism spectroscopy on enantiomeric pairs of all synthesized polymers. The results demonstrate a versatile approach for the asymmetric synthesis of polyisocyanides.

Diagnosis
This species is recognised within the genus Basiceros Schulz, 1906 by the following characteristics: head almost as broad as long, occipital lobes rounded with the relatively straight with a narrow mesal concavity, without presence of continuous crest; petiolar node and postpetiole completely covered with dense pilosity; petiolar node well developed and, in dorsal view, sub-rectangular; petiole with ventral carina with many developed teeth, of different shapes; first gastral tergite with few specialised hairs on its most posterior margin, those longer than basilar pilosity (Fig. 6).
Distribution
This species has few records in the country, limited to the Departments of Amazonas, Meta and Nariño (Probst and Brandão 2022). It is recorded here for the first time in the Department of Caquetá. In the Neotropical Region, the species has also been recorded in Ecuador, Peru and Brazil (Probst and Brandão 2022).
Biology
This species was collected in leaf litter in the Río Hacha Basin. Additionally, it was collected on a log in leaf litter in cloud forest, although only one worker was observed. Probst and Brandão (2022) suggest that B. conjugans feeds on dead arthropods. Furthermore, it is thought that they may prey on termites, a behaviour observed in other species of the genus.

Australian biotechnology companies and networks: methodological issues in the replication of a major US study
Creators: name: Gilding, Michael
name: Bunton, Vikki
Publisher: name: Swinburne
Year: 2024

description: This paper arises from a replication of a major US study on the ‘network logic’ of biotechnology companies. Walter Powell, the leading sociological authority in this field, has argued that such companies are exemplars of new forms of economic and organizational behaviour. He has also observed that ‘this new logic of organising’ might well ‘diffuse globally’, but alternatively national-level institutions might refract ‘common competitive pressures’ and produce ‘divergent responses’ (Powell 2001: 66): hence replication in the Australian context. Yet replication presents many challenges. There is no comparable publicly-available database of Australian biotechnology companies with which to work. There are also a variety of problems in applying the categories of the original study to Australian biotechnology companies and their partner organisations. Some of these problems have implications for the original study. Others arise in the Australian context, on account of differences in the configuration of the Australian industry. On this account, there is a risk that replication might actually obscure the differences that it is designed to address. By implication, replication must involve close attention to the raw data, and adjustment of categories to take into account differences across countries.

description: Обеспечение и регулирование конкуренции в банковской системе, ее оценка остаются сложным вопросом. В отличие от других отраслей экономики регулирование банковских услуг в банковской системе, оценка уровня конкуренции в сфере оказания услуг между банками, достижение ожидаемых результатов являются сложными вопросами. В связи с этими факторами большое значение имеет стабильное функционирование банковской системы и повышение качества услуг. Также негативное влияние на рынок банковских услуг оказывают проблемы, связанные с управлением взаимоотношениями между клиентами банка и банками и знанием информации о финансовых услугах, предоставляемых банками, использованием банковских продуктов по мере необходимости, а также недостаточная финансовая грамотность населения

Synthesis of chromium guanidinate complexes and their activity in ethylene oligomerizationpolymerization
Creators: name: Horvath, Steven
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2010
Subjects: subject: Chemistry, Inorganic.

description: The overall objective in this body of work was to synthesize a new class of chromium complexes containing a bound guanidinate ligand (Chapter 2) and ultimately test these complexes for catalytic activity in ethylene oligomerization/polymerization reactions (Chapter 4). A number of reactions between the chromium guanidinate complexes and alkyl aluminum reagents (Chapter 3) were attempted to gain insight into the nature of the active species in the catalytic cycle. A large majority of the complexes presented in this thesis have been characterized using x-ray crystallography. Additionally a number of dimeric CrII complexes were obtained with bridging guanidinate and alkyl groups. One such complex had an ultra short CrII-Cr II distance of 1.773 A (Steven Horvath, Serge I. Gorelsky, Sandro Gambarotta, Ilia Korobkov Angew. Chem 2008, 47, 9937) and a thorough DFT study was performed on the complex (Chapter 3). The catalytic testing of this new class of chromium guanidinate complexes was very promising and a thorough investigation of the factors that affect the selectivity and activity of the catalysts was performed (Chapter 4).

description: Sedentary time is a modifiable determinant of poor health, and in older adults, reducing sedentary time may be an important first step in adopting and maintaining a more active lifestyle. The primary purpose of this consensus statement is to provide an integrated perspective on current knowledge and expert opinion pertaining to sedentary behaviour in older adults on the topics of measurement, associations with health outcomes, and interventions. A secondary yet equally important purpose is to suggest priorities for future research and knowledge translation based on gaps identified. A five-step Delphi consensus process was used. Experts in the area of sedentary behaviour and older adults (n=15) participated in three surveys, an in-person consensus meeting, and a validation process. The surveys specifically probed measurement, health outcomes, interventions, and research priorities. The meeting was informed by a literature review and conference symposium, and it was used to create statements on each of the areas addressed in this document. Knowledge users (n=3) also participated in the consensus meeting. Statements were then sent to the experts for validation. It was agreed that self-report tools need to be developed for understanding the context in which sedentary time is accumulated. For health outcomes, it was agreed that the focus of sedentary time research in older adults needs to include geriatric-relevant health outcomes, that there is insufficient evidence to quantify the dose–response relationship, that there is a lack of evidence on sedentary time from older adults in assisted facilities, and that evidence on the association between sedentary time and sleep is lacking. For interventions, research is needed to assess the impact that reducing sedentary time, or breaking up prolonged bouts of sedentary time has on geriatric-relevant health outcomes. Research priorities listed for each of these areas should be considered by researchers and funding agencies.

description: Numerous studies deal with composition and molecular processes involved in primary cell wall formation and alteration in Arabidopsis. However, it still remains difficult to assess the relation between physiological properties and mechanical function at the cell wall level. The thin and fragile structure of primary cell walls and their large biological variability, partly related to structural changes during growth, make mechanical experiments challenging. Since, to the best of our knowledge, there is no reliable data in the literature about how the properties of the fully elongated zone of hypocotyls change with age. We studied in a series of experiments on two different seed batches the tensile properties the region below the growth zone of 4 to 7 day old etiolated Arabidopsis hypocotyls. Additionally, we analysed geometrical parameters, hypocotyl density and cellulose content as individual traits and their relation to tissue mechanics. No significant differences of the mechanical parameters of the non-growing region between 5–7 day old plants could be found whereas in 4 day old plants both tensile stiffness and ultimate tensile stress were significantly lower than in the older plants. Furthermore hypocotyl diameters and densities remain almost the same for 5, 6 and 7 day old seedlings. Naturally, hypocotyl lengths increase with age. The evaluation whether the choice–age or length—influences the mechanical properties showed that both are equally applicable sampling parameters. Additionally, our detailed study allows for the estimation of biological variability, connections between mechanics and hypocotyl age could be established and complement the knowledge on biochemistry and genetics affecting primary plant cell wall growth. The application of two different micromechanical devices for testing living Arabidopsis hypocotyls allows for emphasizing and discussing experimental limitations and for presenting a wide range of possibilities to address current and future questions related to plant cell wall mechanics, synthesis and growth in combination with molecular biology methodologies.
