Human bone: the tissue characteristics determining its mechanical behaviour
Creators: name: Ohman, Anna Maria Caroline <1980>
Publisher: name: Alma Mater Studiorum - Università di Bologna
Year: 2011
Subjects: ING-IND/34 Bioingegneria industriale

description: The present thesis illustrates the research carried out during the PhD studies in Bioengineering. The research was aimed to characterise the human bone tissue, with particular regard to the differences between cortical and trabecular bone. The bone tissue characteristics that affect its mechanical properties were verified or identified, using an experimental approach, to corroborate or refute hypotheses based on the state of the art in bone tissue biomechanics. 

The studies presented in the present PhD thesis were designed to investigate aspects of bone tissue biomechanics, which were in need of a more in-depth examination since the data found in the literature was contradictory or scarce. In particular, the work was focalised on the characterisation of the basic structure of the bone tissue (groups of lamellae), its composition, its spatial organisation (trabecular bone microarchitecture) and their influence on the mechanical properties. 

In conclusion, the present thesis integrates eight different studies on the characterisation of bone tissue. A more in-depth examination of some of the aspects of bone tissue biomechanics where the data found in the literature was contradictory or scarce was performed. Bone tissue was investigated at several scales, from its composition up to its spatial organization, to determine which parameters influence the mechanical behaviour of the tissue. It was found that although the composition and real density of bone tissue are similar, the differences in structure at different levels cause differences between the two types of bone tissue (cortical and trabecular) in mechanical properties. However, the apparent density can still be considered a good predictor of the mechanical properties of both cortical and trabecular bone. Finally, it was found that the bone tissue characteristics might change when a pathology is present, as demonstrated for OA.

description: We investigate non-perturbative pair production from vacuum (the Schwinger effect) in the focal region of two counter-propagating, ultra-short laser pulses with sub-cycle structure. We use the quantum kinetic formulation to calculate the momentum spectrum of created particles and show the extreme sensitivity to the laser frequency $ω$, the pulse length $τ$ and the carrier-envelope absolute phase $ϕ$. We apply this formalism to both fermions and bosons to illustrate the influence of quantum statistics in this type of electric background field.

description: efforts to initiate and sustain broad-based development activity. The study showed that though a variety of studies were conducted, they were initiated by and conducted with the intimate involvement of Pictou County residents who had been and would continue to be affected by the decisions arrived at. The study further showed that Pictou County residents were fast learning through their involvement that so much of what would likely happen in Pictou County depended on the initiatives they would take. What was happening in Pictou County by virtue of the Development Opportunities Project was found to embrace quite closely the concepts which form the theory of social learning. The study concluded by saying that while great care was necessary to rule out cause and effect relationships that may be spurious, the previous federal and provincial regional development planning efforts seemed to have had marginal influence on the economic well-being of residents in Nova Scotia regions and may have even hindered social and political development. On the other hand, evidence appeared to exist to suggest that social and political development was taking place as a result of the Development Opportunities Project. No hard data existed on the economic effects of the Project. Generally, however, this study suggested that regional development planning that strengthens the process of social learning within the region will have more fundamental and worthwhile effects than the more traditional approaches.

description: Abstract

Objective: Walking aids are widely prescribed for supporting ambulation in stroke patients. Many factors must be considered to decide which walking aid will be prescribed, including the energy cost and the walking performance produced by using the walking aids. This research aimed to investigate the differences between the Physiological Cost Index (PCI), the Timed Up and Go (TUG) Test, and walking speed in stroke patients according to the type of walking aid used. Methods: A total of 26 patients with subacute stroke were sampled in a consecutive sampling at Malang Saiful Anwar General Hospital's PM&R outpatient clinic. Each patient completed walking with four different walking aids: a fixed walker, a rollator, a quad cane, and a single-point cane, resting between tests until the patient's heart rate returned to its resting level. We measure the PCI using heart rate and walking speed during a 10-meter walk test (10MWT) and mobility performance during the Timed Up and Go (TUG) Test. Results: The PCI was lower with the single-point cane (p<0.001), and the walking speed and mobility performance were higher with the single-point cane (p<0.001) than with any other walking aid. Conclusion: Our research revealed that a single-point cane requires less energy and permits more excellent performance for stroke patients who can already walk with a walking aid.

We compute the period lattice of the intermediate Jacobian of $F$ and study its Fano surface $S$. We compute also the set of fibrations of $S$ onto a curve of positive genus and the intersection between the fibres of these fibrations. These fibres generate an index 2 sub-group of the Néron-Severi group and we obtain a set of generators of this group. The Néron-Severi group of $S$ has rank $25=h^{1,1}$ and discriminant $11^{10}$.

description: We estimated the galactic model parameters for a set of 20 intermediate-latitude fields with galactic longitudes 0=6.52% and =0.35%, respectively, a result different than the one cited for high-latitude fields. The thin disc's scaleheight is 325 pc in the galactic centre changes to 369 pc in the third quadrant, which confirms the existence of disc flare, whereas the thick disc scaleheight is as large as 952 pc at galactic longitude l=20 and 10% lower at l=160, which confirms the existence of the disc long bar in the direction l=27. Finally, the variation of the axis ratio of the halo with galactic longitude is almost flat, =0.56, except a slight minimum and a small maximum in the second and third quadrants, respectively, indicating an effect of the long bar which seems plausible for a shallow halo. We estimated the metallicities of unevolved G-type stars and discussed the metallicity gradient for different vertical distances. The metallicity gradient is d[M/H]/dz=-0.30 dex kpc$^{-1}$ for short distances, confirming the formation of this region of the Galaxy by dissipational collapse. However, its change is steeper in the transition regions of different galactic components. The metallicity gradient is almost zero for inner halo (5

description: Abstract

Accounting Information Systems (AIS) have played a crucial role in financial management and accounting within various organizations, including both public and private entities. The implementation of AIS has yielded positive effects in enhancing the efficiency and reliability of financial information. However, a lack of understanding and awareness regarding the significance of AIS, coupled with insufficient support from management, as well as limited efforts in socialization and training, has resulted in the underutilization of AIS. This research aims to analyze the usage and control of accounting information systems at the Ministry of Youth and Sports. The research method employed is qualitative with a phenomenological approach, allowing for an in-depth exploration of individuals' experiences and perceptions regarding AIS implementation at Kemenpora. The research findings indicate that the implementation of AIS has indeed had a positive impact on improving financial information efficiency and reliability. However, the underutilization of AIS at Kemenpora, primarily stemming from a lack of understanding and awareness of its importance, has hindered optimal performance.

description: The role and importance of nano-particles for interstellar chemistry and beyond is explored within the framework of The Heterogeneous dust Evolution Model at the IaS (THEMIS), focussing on their active surface chemistry (nascence), the effects of nitrogen doping and the natural selection of interesting nano-particle sub-structures. Nano-particle driven chemistry, and in particular the role of intrinsic epoxide-type structures could provide a viable route to the observed gas phase OH in tenuous interstellar clouds en route to becoming molecular clouds. The aromatic-rich moieties present in asphaltenes likely provide a viable model for the structures present within aromatic-rich interstellar carbonaceous grains. The observed doping of such nano-particle structures with nitrogen, if also prevalent in interstellar dust, is likely to have important and observable consequences for surface chemistry and the formation of pre-cursor pre-biotic species.

description: We report extensive spectroscopic and differential photometric BVRI observations of the active, detached, 1.309-day double-lined eclipsing binary IM Vir, composed of a G7-type primary and a K7 secondary. With these observations we derive accurate absolute masses and radii of M(1) = 0.981 +/- 0.012 M(Sun), M(2) = 0.6644 +/- 0.0048 M(Sun), R(1) = 1.061 +/- 0.016 R(Sun), and R(2) = 0.681 +/- 0.013 R(Sun) for the primary and secondary, with relative errors under 2%. The effective temperatures are 5570 +/- 100 K and 4250 +/- 130 K. The significant difference in mass makes this a favorable case for comparison with stellar evolution theory. We find that both stars are larger than the models predict, by 3.7% for the primary and 7.5% for the secondary, as well as cooler than expected, by 100 K and 150 K, respectively. These discrepancies are in line with previously reported differences in low-mass stars, and are believed to be caused by chromospheric activity, which is not accounted for in current models. The effect is not confined to low-mass stars: the rapidly-rotating primary of IM Vir joins the growing list of objects of near-solar mass (but still with convective envelopes) that show similar anomalies. The comparison with the models suggests an age of 2.4 Gyr for the system, and a metallicity [Fe/H] of approximately -0.3 that is consistent with other indications, but requires confirmation.

description: Organised crime tightens its corrupting influence on politics through violent intimidation. Anti-crime measures that increase the cost of corruption but not of the exercise of violence might accordingly lead mafia-style organizations to retaliate by resorting to violence in lieu of bribery. On the other hand, this kind of anti-crime measure might also induce criminal clans to go inactive, owing to the lower expected payoff from the “business” of influencing politics, which would reduce violence. To determine which of these possible effects is prevalent, we undertake an empirical assessment of the impact of city council dissolution for mafia influence in Italy as prescribed by Decree Law 164/1991 in discouraging violence against politicians in the period 2010-2019. Our difference-in-differences analysis shows that in the dissolved municipalities the enforcement of the Law reduces violence and that the effect persists (at least) for two electoral rounds. The most likely driving channel of this result is the renewed pool of politicians elected after compulsory administration. These findings are robust to a series of endogeneity tests.

description: Abstract

This paper investigated the determinants of maternal mortality across sixteen West African nations from 2000 to 2022, employing robust econometrics methods such as Pooled Mean Group (PMG) and Fully Modified Ordinary Least Square (FMOLS). Grounded in life-course perspective theory, the study explored the interplay between clinical determinants and socio-economic factors including life expectancy, political stability, fertility rate, HIV prevalence, education, and healthcare expenditure. Findings unveil significant long-run and short-run determinants affecting maternal mortality. While life expectancy exhibits a statistically insignificant negative relationship in the PMG model, the FMOLS model highlights a significant negative association, emphasizing methodological robustness. Contrarily, political stability, initially appearing positively significant, loses significance in the FMOLS model, indicating nuanced dynamics. The positive and highly significant connection between fertility rate and maternal mortality aligns with economic theory, highlighting the strain on healthcare resources. HIV/AIDS prevalence emerges as a notable determinant, urging targeted interventions. Health expenditure's nuanced relationship underscores the importance of effective utilization, advocating strategic investments. Education expenditure, while showing contradictory results, emphasizes the need for targeted education policies. Policy recommendations advocate for a multifaceted approach, prioritizing strategic investments in healthcare infrastructure, targeted HIV/AIDS programs, comprehensive family planning services, and education policies. Leveraging political stability for effective policy implementation is paramount, ensuring tangible improvements in maternal health outcomes in West Africa.

description: The origin of the diffuse interstellar bands is one of the longest-standing mysteries of the interstellar medium is explored within the framework of The Heterogeneous dust Evolution Model at the IaS (THEMIS). The likely nature of the diffuse interstellar band carriers and their evolution is here explored within the framework of the structures and sub-structures inherent to doped hydrogenated amorphous carbon grains in the interstellar medium. Based on the natural aromatic-rich moieties (ashphaltenes) recovered from coal and oil the likely structure of their interstellar analogues is investigated within the context of the diffuse band problem. It is here proposed that the top- down evolution of interstellar carbonaceous grains, and in particular a-C(:H) nano-particles, is at the heart of the formation and evolution of the diffuse interstellar band carriers and their associations with small molecules and radicals such as C2, C3, CH and CN. It is most likely that the diffuse interstellar bands are carried by dehydrogenated, ionised, hetero- cyclic, aromatic rich moieties that form an integral part of the contiguous structure of hetero-atom doped hydrogenated amorphous carbon nano-particles and their daughter fragmentation products.

description: The work of this thesis has been focused on the characterisation of inorganic membranes for the hydrogen purification from steam reforming gas.
Composite membranes based on porous inorganic supports coated with palladium silver alloys and ceramic membranes have been analysed.
A brief resume of theoretical laws governing transport of gases through dense and porous inorganic membranes and an overview on different methods to prepare inorganic membranes has been also reported.
A description of the experimental apparatus used for the characterisation of gas permeability properties has been reported.
The device used permits to evaluate transport properties in a wide range of temperatures (till 500°C) and pressures (till 15 bar).
Data obtained from experimental campaigns reveal a good agreement with Sievert law for hydrogen transport through dense palladium based membranes while different transport mechanisms, such as Knudsen diffusion and Hagen-Poiseuille flow, have been observed for porous membranes and for palladium silver alloy ones with pinholes in the metal layer. Mixtures permeation experiments reveal also concentration polarisation phenomena and hydrogen permeability reduction due to carbon monoxide adsorption on metal surface.
Dust evolution, a global view: III. Core/mantle grains, organic nano-globules, comets and surface chemistry

description: Within the framework of The Heterogeneous dust Evolution Model at the IaS (THEMIS) this work investigates in detail the surface processes and chemistry relating to core/mantle interstellar and cometary grain structures and its influence on the nature of these fascinating particles. It appears that a realistic consideration of the nature and chemical reactivity of interstellar grain surfaces could self-consistently and within a coherent framework explain: the anomalous oxygen depletion, the nature of the CO dark gas, the formation of 'polar ice' mantles, the red wing on the 3 um water ice band, the basis for the O-rich chemistry observed in hot cores, the origin of organic nano-globules and the \sim 3.2 um 'carbonyl' absorption band observed in comet reflectance spectra. It is proposed that the reaction of gas phase species with carbonaceous a- C(:H) grain surfaces in the interstellar medium, in particular the incorporation of atomic oxygen into grain surfaces in epoxide functional groups, is the key to explaining these observations. Thus, the chemistry of cosmic dust is much more intimately related with that of the interstellar gas than has previously been considered. The current models for interstellar gas and dust chemistry will therefore most likely need to be fundamentally modified to include these new grain surface processes.

description: We investigate the properties of "star forming regions" in a previously published numerical simulation of molecular cloud formation out of compressive motions in the warm neutral atomic interstellar medium, neglecting magnetic fields and stellar feedback. In this simulation, the velocity dispersions at all scales are caused primarily by infall motions rather than by random turbulence. We study the properties (density, total gas+stars mass, stellar mass, velocity dispersion, and star formation rate) of the cloud hosting the first local, isolated "star formation" event in the simulation and compare them with those of the cloud formed by a later central, global collapse event. We suggest that the small-scale, isolated collapse may be representative of low- to intermediate-mass star-forming regions, while the large-scale, massive one may be representative of massive star forming regions. We also find that the statistical distributions of physical properties of the dense cores in the region of massive collapse compare very well with those from a recent survey of the massive star forming region in the Cygnus X molecular cloud. The star formation efficiency per free-fall time (SFE_ff) of the high-mass SF clump is low, ~0.04. This occurs because the clump is accreting mass at a high rate, not because its specific SFR (SSFR) is low. This implies that a low value of the SFE_ff does not necessarily imply a low SSFR, but may rather indicate a large gas accretion rate. We suggest that a globally low SSFR at the GMC level can be attained even if local star forming sites have much larger values of the SSFR if star formation is a spatially intermittent process, so that most of the mass in a GMC is not participating of the SF process at any given time.

description: Abstract

MSM are one of the groups at risk of contracting HIV and AIDS because their safe sexual practices are still low. The low level of safe sexual practices among MSM can increase the prevalence of HIV and AIDS. The health belief model can explain the safe sexual behavior of MSM with HIV. This research aims to analyze factors related to safe sexual behavior among men with HIV at the Bandung City Regional General Hospital. This research uses an analytical correlation method with a cross-sectional research design. The sample used was 89 MSM using a purposive sampling technique. Data collection used the Indonesian version of the Safe Sex Behavior Questionnaire instrument and a questionnaire on factors related to safe sexual behavior. Data analysis uses the Pearson product-moment test and linear regression test. Results: Bivariate results showed that factors related to safe sexual behavior were perceptions of obstacles (p 0.007), perceptions of benefits (p 0.000), cues to action (p 0.000), and self-confidence (p 0.004). The most dominant factor related to safe sexual behavior is the perception of benefits (β 0.249, p 0.032, R2 0.025), which explains around 25.8%, while the rest is other influencing factors. Most respondents have the perception that safe sexual behavior, namely using condoms and utilizing voluntary counseling and testing (VCT), has benefits for them. The higher the perception of benefits, the better the safe sexual behavior of MSM. Nursing care that is carried out by prioritizing the rights and privacy of MSM and by motivating safe sexual behavior can encourage MSM to engage in safe sexual behavior.

description: An experimental investigation is made of sub-recoil cooling by velocity selective coherent population trapping in a two-level system in Sr. The experiment is carried out using the narrow linewidth intercombination line at 689 nm. Here, the ratio between the recoil shift and the linewidth is as high as 0.64. We show that, on top of a broader momentum profile, subrecoil features develop, whose amplitude is strongly dependent on the detuning from resonance. We attribute this structure to a velocity selective coherent population trapping mechanism. We also show that the population trapping phenomenon leads to complex momentum profiles in the case of highly saturated transitions, displaying a multitude of subrecoil features at integer multiples of the recoil momentum.

description: Abstract

The association between udder and teat biometrics with occurrence of subclinical mastitis (SCM) in dairy cows was investigated in this study. The relationship of udder and teat biometrics with udder health status were analyzed by using Chi- square test, one-way ANOVA, and a binomial logistic regression model. Funnel teats and round udder were the most common, and their distribution among the breeds differed. Teat shape (TS) was associated with SCM, and the cows with bottle shaped teats experienced the highest odds of SCM, while cylindrical teats were least affected. The udder SCC was higher in Jersey while quarter SCC was larger in fore teats in both Jersey and HF. Similarly, quarter and udder SCC were higher in SCM cows compared to the healthy ones. Teat length (TL), teat diameter (TD), and teat-to-floor distance (TFD) were associated with increased risk of SCM. Teats were longer and wider in HF and placed farther from floor, while Lulu had the shortest and thinnest teats placed nearer to the floor. The SCM animals had low set udders, longer and thicker teats with smaller udder length, width, TFD and distance between teats than in healthy animals. The increase in TL and TD and decrease in TFD showed an intensification of the risk of SCM by 11.55 folds in fore, 3.88 folds in hind, 9.58 times in right teats and 8.52 folds in thicker teats. Each unit increase in TFD cuts off probability of SCM by 43% in fore, 11% in hind and 10% in left teats. Thus, biometric traits are important characteristics for SCM management and need to be duly considered in the selection and breeding program of dairy cows to cut off the incidence of SCM.

description: This thesis provides a comprehensive treatment of agriculture in Canada as examined from the viewpoint of modern production theory. This theory has it's origins in Hicks (1946) who developed the implications of profit-maximizing behavior in the context of a multiple input, multiple output technology. The main body of the thesis is divided into three major papers. In the first paper we provide a comprehensive overview of the concepts and methodology which have been employed in making observations of agricultural production during the period 1926-1970. In the second and third papers of the thesis we apply the previously analysed data base to the problem of measuring the rate of increase in total factor productivity during the post-war period and to estimating the internal structure of agricultural production during the post-war period. The second paper is devoted to measuring the growth in total factor productivity during the post-war period. Two problems are explicitly examined: i) the calculation of rental prices or user costs for durable inputs (see Jorgenson and Griliches (1967) (1972), Diewert (1972) Section VI "Producer Behavior when Depreciation Rates are Variable", and King (1974)) and (ii) the aggregation of the numerous inputs and outputs (see Jorgenson and Griliches (1972) and Diewert (1974a)). In the third paper, the data base is applied to the problem of modeling and estimating empirically a multiple-output production function for the Canadian Agricultural Sector. This study not only provides insight into the internal structure of production within the agricultural sector, but also allows many of the assumptions and implications of the neoclassical theory of production to be tested empirically. In each of the applications the results achieved are directly related to the accounting framework by which the various inputs and outputs are measured and to the way in which the data has been handled. Thus a major concern in the applications sections is with possible ways by which the data and the studies may be improved.

description: Abstract

Background/aim: Analysis compounds containing antioxidant activity of magenta plant leaves (Peristrophe Bivalvis (L.) Merr) in preventing oxidative stress and predicting its potential as a candidate medicinal compound for cervical anticancer. Materials and methods: The cervical anticancer activity of Peristrophe Bivalvis (L.) Merr was conducted by in silico and in vivo methods. The in silico research design was performed using molecular docking techniques, while the in vivo research design was carried out using Elisa by examining the levels of MDA, SOD, GSH and Nrf2 tissue in experimental animal models that experienced oxidative stress. Results: The ethanol extract of magenta leaves has antioxidant activity that can prevent oxidative stress through its activity in reducing Malondialdehyde (MDA) levels, increasing Superoxide Dismutase levels and Glutathione levels through the regulation of Nuclear Factor Erythroid Related Factor-2 (Nrf2). The molecular docking results of magenta leaf compounds showed a high affinity to target proteins, namely Nrf2/Keap1, CDK2, and EGFR. Conclusion: This study concluded that the ethanol extract of magenta leaves has good antioxidant activity. The molecular docking approach also shows the potential of active compounds from magenta leaves ethanol extract as cervical anticancer agents.

description: The electromagnetic form factors are the most fundamental quantities to describe the internal structure of the nucleon and the shape of a spatially extended particle is determined by its intrinsic quadrupole moment which can be related to the charge radii. We have calculated the electromagnetic form factors, nucleon charge radii and the intrinsic quadrupole moment of the nucleon in the framework of chiral constituent quark model. The results obtained are comparable to the latest experimental studies and also show improvement over some theoretical interpretations.

description: Abstract

Bureaucratic Reform (RB) based on Presidential Decree Number 81 of 2010 concerning the Grand Design of Bureaucratic Reform 2010-2025 in practice must be carried out by all Ministries/Institutions/Dinas/Institutions (K/L/D/I) in an innovative, creative and monitored manner institutional. The government also then issued Presidential Regulation Number 39 of 2019 concerning Data Management. Indonesia's One Data Policy (SDI) is expected to be a strategy for improving data governance to produce data that is accurate, up-to-date, integrated and accountable so that it can become the foundation for determining effective and appropriate policies. Indonesia's One Data Policy (SDI) is expected to be a strategy for improving management data to produce accurate, timely, integrated and accountable data which forms the basis for the creation of effective and targeted policies. The TNI AD Data Center is an Indonesian military facility that contains electronic systems and related components to be used and used for the placement, storage and processing of data in support of the Indonesian military information system. Data center facility infrastructure includes four aspects. First, infrastructure that guarantees the continuity of business processes when something critical and dangerous occurs in the data center. Internalization of RB, SPBE, and realizing SDI within the TNI AD institution must be realized through the arrangement of the Information System in order to further support the implementation of the Main Tasks of the TNI AD. The TNI AD needs to conceptually manage the data center, data processing architecture, network centralization, human resources, software and organizational management.

description: Camptothecin, (CPT) is a pentacyclic alkaloid isolated for the first time from the
Chinese tree Camptotheca acuminata, and which has soon attracted the attention of
medicinal chemists and pharmacologists due to its promising anti-cancer activity
against the most aggressive histo-types. So far, most of the synthesized camptothecin
analogues are A and B ring modified compounds, which have been prepared via
synthetic or semi-synthetic routes. To the best of our knowledge, a very limited number
of C, D, or E ring modified analogues of CPT have been reported; moreover, the few
derivatives known from the literature showed a reduced or no biological activity.
This dissertation presents synthetic studies on camptothecin new derivatives along with
the development of a new and general semi-synthetic methodology to obtain a large
variety of analogues.
We report here the semi-synthesis of a new family of 5-substituted CPT's, along with
their biological activity evaluation, which will be compared with reference compounds.
The use of carrier-linked prodrugs has emerged as a useful strategy to overcome some
of the drawbacks related with the use of the parent drug, such as low solubility,
membrane permeability properties, low oral absorption, instability, toxicity, and nontargeting.
Herein we report CPT-prodrugs synthesized via ring opening of the lactone
moiety as 17-O-acyl camptothecin tripartate conjugates, which bear a polyamine side
chain with different architectures, as the carriers.
Moreover, we found that the replacement of the oxygen atom with sulphur on the
piridone D-ring, dramatically improves the potency of the novel 16a-thio-camptothecin
derivatives, opening new possibilities in the modelling of this class of compounds.

description: Homogeneous Multi-scale Entanglement Renormalization Ansazt (MERA) state have been recently introduced to describe quantum critical systems. Here we present an extensive analysis of the properties of such states by clarifying the definition of their transfer super-operator whose structure is studied within a informational theoretical approach. Explicit expressions for computing the expectation values of symmetric observables are given both in the case of finite size systems and in the thermodynamic limit of infinitely many particles.
