The solution of this system will be found by using the method of the least squares:where represents the transpose matrix and is the inverse matrix operation. The Doppler evaluation made for the same teeth placed under the bridge gave results of the same type, so the two results of the methods, the classical, clinical (but approximate one) and of the more accurate (but more elaborate) method developed in this study confirm each other. The first step in order to obtain is to built the overdetermined system of equations [32, 33]:which can be written in the formal form where [X] is a m × 2n matrix, {s} is a 2n × 1 column matrix, and {x} is a m × 1 matrix (where m ≥ 2n). In each of them, the same tooth (i.e., the first right mandibular molar 46) was absent and three metal-ceramic FPPs were made. The discussion on these aspects is completed in Section 6. The authors declare that there are no conflicts of interest regarding the publication of this paper. From these results, we concluded that the developed equations indicate the importance of inhibiting the weight loss and can be used as a tool for assessment of quality or storage conditions of Shine Muscat fruit after harvest. literature, the mechanical properties of this zone are unknown and remain a rarely treated subject. The color changes of samples were confirmed in LHS; therefore, it was assumed that the low humidity or water loss may reflect their colors. Elastometric parameters of the 47 tooth-periodontal tissue system—with and without an FPP. Weight loss of “Shine Muscat” bunches during storage. For simplicity, to demonstrate the validity of the investigation method proposed, two teeth separated by a missing one are considered, and then the FPP which unites them. The bond is a result of mechanical interlocking provided by epitaxic growth of cement hydration products on the aggregate surface and by chem- The chroma, C, of samples did not change in HHS but gradually decreased in LHS with increasing storage duration (Figure 3(b)). The classical model of a single degree of freedom (DOF) damped oscillator with viscous damping. Therefore, one cannot compare their state of health based on the values of their υμ, but only based on the values of their Aμ, as performed above. To achieve this, we utilize a repetitive impact exciter represented by a Periotest device in order to periodically apply short impulses normal to the crown region of the teeth, as shown in Figure 3. Review articles are excluded from this waiver policy. Ten to twelve samples were used for the measurements.where , , and indicate the color data of nonstored samples. In the latter case, the expected average of the parameters is reached, as the healthier tooth losses some of the quality of the tooth-tissue system, while the less healthier tooth gains some of this quality. Strength 9. To achieve more accurate measurements, the impact response (the “free response”) of the tooth has to contain several components; therefore, After the FPP is in place, the amplitudes, However, regarding the previous aspect, one can successfully compare the situation of the blunts before and after placing the FPPs: for the blunt 45, the values of. 2018 Aug;113:151-160. doi: 10.1016/j.bone.2018.05.015. The three remaining movements should be possible—with certain parameters. Toughness 3. As demonstrated in the examples considered, these parameters can be utilized to analyse and to compare the status of the teeth affected by the periodontal disease and what happens after the FPP is set in place. J Appl Physiol (1985). The free response of two blunts for an impact test: blunt 45 (a) without a bridge/FPP and (b) with a bridge/FPP, and blunt 47 (c) without a bridge/FPP and (d) with a bridge/FPP. The Mooney-Rivlin material model is a hyperelastic material model and is available for 2D, brick, tetrahedral, membrane, and shell elements. In addition to these properties, it may be necessary to define some Isotropic Material Properties. However, with good foundry prac-tices and the use of available present process control tools, exceptionally strong, sound aluminum-copper alloys can be cast routinely.

System (5), which represents n-coupled oscillations is therefore expressed as follows: In the absence of the excitation force, Equation (5) becomes. The actual temperature and RH during each storage test were 14.8 ± 0.2°C, 96.2 ± 1.5% (HHS) and 15.1 ± 0.2°C, 39.4 ± 5.3% (LHS). Another important aspect that has to be investigated is the PDL system for the teeth abutments under dental bridges/fixed partial prostheses (FPPs). (v)The eigenfrequencies υμ are higher for a healthy periodontal tissue, which acts as a strong spring for the system, and are smaller for an affected periodontal tissue, which acts as a weaker spring. The method to be developed is intended to be utilized for such a specific situation, when it is important to monitor (or to evaluate) the mobility of a tooth under a prosthetic construct without taking out that bridge. (b)The z-axis translation (Figure 2) is the movement with the smallest oscillatory amplitudes Aμ and with one of the highest damping factors ξμ—the latter aspect due to the fact that the rigidity on the z-axis is the highest, as this movement is related to the adaptation to the masticatory forces and thus to the necessary stability of each tooth in the alveole of their gum. Therefore, it was assumed that the visual changes of samples in HHS were inhibited compare to that of LHS.

Medraj Mech. The PPA used in this research work was subjected to control burning of Plantain peel into ash, which was grinded and passed through 75Âµmm BS sieve. The other two functions can be determined from the one that is measured. The investigations were performed after preparing the abutments and after the FPP insertion. (i)The classical one-dimensional (1D) vibrational system with viscous damping consists of a mass m, an elastic element with an elastic constant k, and a damper characterized by a constant c (Figure 1). The same aspect can be concluded/is confirmed from the z-translations, which for the blunt 45 are larger, while for blunt 47 remain approximately constant. However, ΔE increased in LHS with increasing storage duration (Figure 3(a)). Section 5 presents the experimental results, while Section 6 discusses them and extracts rules-of-thumb for such a multiparametric analysis. The modal elastic constant and the damping constant are therefore given as follows: As an option, the density of the elastic constant and of the damping constant can also be defined as the elastic and as the damping constant on the unity of modal mass: In Tables 1 and 2, the parameters estimated for the abutments 45 and 47, respectively, are presented—for the corresponding records obtained without and with the dental bridge/fixed partial prostheses (FPPs). The latter are taking into account the tooth mass, the head mass, and the mandibular and the maxillary tooth mass. We consider that the recorded signal is sampled with a sampling frequency in accord with Shannon's theorem; thus, the sampling frequency obeys the condition , where represents the maximum frequency of the signal. The objective of this study was to identify the changes in mechanical and color properties of Shine Muscat fruit during storage. 4, pp. An accurate damped response was selected for each case from the series of impulses. Malleability 5. Positioning of the Periotest and of the Doppler ultrasound sensor towards an investigated tooth. Effect of heat treatment on the mechanical properties 3413 Figure (1) DSC curve for AA2014 alloy 3.2 Ideal heat treatment The fig.2.represent aging curve shows the response of age hardening treatments on hardness, the difference in hardness with the aging time displayed different peaks conforming to the precipitation of different phases. The resulting vibrations of the tooth are measured using the laser Doppler vibrometry [12, 13]. It supports the tooth in contact with compressive masticatory forces. In Figure 5, the responses for the abutment 45 and for the abutment 47 are presented, in the case of the blunt: 5(a) without and 5(b) with the bridge. Some parts of this study were supported by the Japan Society for the Promotion of Science KAKENHI Grant Number JP 17K15352 (Grant-in-Aid for Young Scientists (B)) and CORONA CORPORATION, Japan. Finally, the mechanical parameters of the free n-dimensional vibrating system can be expressed in three different ways: using the damping factors and the pseudoangular frequencies , ; using the modal parameters ; or using the damping factors and the natural angular frequencies , the latter equivalent to . Cosmin Sinescu, Virgil-Florin Duma, Marius Manole, and Gheorghe Eugen Draganescu have equal contributions. A set of mechanical parameters of the tooth-PDL system is obtained, and a new method for the evaluation of these parameters from the free response of the tooth is introduced. Strain was calculated as the ratio of deformation to the initial height of the sample. It is characterized, in a generalization of the discussion on the model (i), by a classical system of second-order differential equations:where is the n-dimensional column matrix of the generalized coordinates; is the n-dimensional column matrix of the excitation forces; [m] represents the n × n-dimensional matrix of inertia (in our case a diagonal matrix, which contains the masses and the moments of inertia); [c] is the damping n × n symmetric matrix; and [k] is the stiffness matrix, which is also n × n symmetric. However, in time, this system may be affected by periodontal diseases, which induce changes in the tooth mobility, with consequences on the well-being of the patient. If an impact is applied to the mass in the absence of the excitation force (i.e., F = 0) and for the case of an oscillatory regime (i.e., for ), the free response of the system can be written in the real or complex form aswhere , , and are the integration constants. Figure 1 shows weight loss of the Shine Muscat bunches during storage. In the presence of noise or of a reduced number of measured values, nonparametric methods like the autoregressive or the minimum variance method have to be utilized [27, 30]. The results indicated that the equations may be applied for easy assessment of these physical properties using only weight loss data as well as the importance of inhibiting weight loss of Shine Muscat fruit during storage. In addition, chlorophyll degradation is one of the factors of the color changes in ripening fruit [18]. Their usefulness, the efficiency of the related measuring method to assess the mobility of the teeth affected by periodontal diseases, and the effects of the FPP are finally investigated. Figures 2(a)–2(c) show the changes in mechanical properties of the samples during storage. We thus consider in the first step of this study different individual teeth, and in the second step, the dental bridge/FPP system which unites such teeth. Copyright © 2018 Takashi Watanabe et al. Finally, the austenitic core transforms into ferrite and pearlite. We showed the changes in weight loss and other physical properties and proposed equations to estimate the physical properties based on weight loss data. Each corresponding reduced eigenfrequency is. Mechanical properties of polymer grafted nanoparticle composites. Its biomechanical behaviour is still not well understood although this topic has been studied for almost 100 years [2–5]. Weight loss (%) was calculated using the following equation:where is the mass of bunches during storage and is the mass of nonstored bunches. Therefore, in performing such an analysis, one may use only two or even one of the DOF considered, while the other(s) can be used to confirm the results obtained—as it has been seen from the above discussion. The study demonstrates that this method can provide the dentist with the necessary objective evaluations regarding the properties and health of the tooth-PDL system, as well as of the construct that is obtained after installing a dental bridge. (vii)Using the values of the eigenfrequencies υμ, one can make a comparison between the different DOFs but, again, for the same tooth. (Doc: STI/277 17, June 2004). Mechanical Properties and Microstructure V. Musonda1, a*, E.T Akinlabi1, T.C Jen1 ... 2018. of the heat flow from the red-hot core to the low surface temperature. However, these eigenfrequencies cannot be used for practical investigations of the tooth mobility because they are strongly dependent on the links that the tooth has with the gingiva and with the jaw bone. In this research, we show that encapsulation of polymer chains into MOF nanochannels can effectively restrain the breakage of coordination bonding in … Nanocomposites: Vol. In fact, the color of Shine Muscat fruit at the preharvesting stage was previously investigated [8, 9]; however, the changes in color properties of the fruit during storage were not investigated. (2020). Click here to see this story as it appears in the March-April 2018 issue of Metal Casting Design & Purchasing. This research is aimed at investigating the effect of using plantain peel ash (PPA) obtained from plantain peel as a partial replacement of ordinary Portland cement (OPC) on the mechanical properties of concrete. As it can be seen from the analysis below, from the three movements identified above, it is even enough to use only the first two, i.e., those that are the easiest to point out, as they have the highest and the smallest amplitudes, respectively. Table 1 shows all calculated mechanical properties at the breaking point during compression tests. Review articles are excluded from this waiver policy. This brief analysis shows that one should describe the tooth-PDL system as a linear, coupled vibrating system with n DOFs—where a probable useful value, as pointed out above, is n which equals 3 and with viscous damping. As a second step, with the aid of the solution , a 2n-degree algebraic equation can be built:which has its solutions dependent on the modal parameters : The modal parameters finally are obtained as a set of n pairs of complex numbers: The modal damping factor and the pseudoangular frequency will therefore be the absolute values ofwhere . Resilience 10. The periodontal ligament (PDL) system connects the tooth with the alveolar bone [1]. These can be considered the elastometric parameters which characterize the status of the tooth-PDL tissue system [32, 33], affected in a certain degree by parodonthosis [34]. We consider the system as a linear vibrational one with viscous damping and n degrees of freedom. Eighteen samples were used for the measurements. Future work in our groups includes the study of the variation of these parameters with the repeated application of the impacts, which constitutes the so-called adaptation phenomenon. Investigation of Mechanical Properties of CFRP/EVA Laminated Composites According to Tensile and Flexure Test. [5]. Nevertheless, the strain and elasticity revealed that the mechanical properties were not recovered (Figures 2(b) and 2(c)). The Lab data were recorded, where L indicates lightness or luminance, a indicates chromaticity on a green (−) to red (+) axis, and b indicates chromaticity on a blue (−) to yellow (+) axis [7]. Again, like for the amplitudes Aμ, an average of the initial values is achieved after placing the FPPs, in accordance with the conclusion obtained in point (iv). The other physical properties—breaking strain, elasticity, color differences, and chroma—could be estimated using the weight loss data and simple equations (R2 = 0.81–0.94). Several devices and methods have been therefore introduced in order to provide quantitative measurements regarding the tooth mobility; they are an alternative to purely empirical tests. Environmental Technology: Vol. Macromolecular Research, CrossRef; Google Scholar Komatsubara investigated the acceptability values of some color parameters for human [16] and showed that the ΔE can be used as an index of the allowable color differences for the visual perception. Possible elementary motions of the tooth (considered as a rigid body): the displacements (. The mechanical properties—stress, strain, and elasticity—at the break point were examined by compression tests. The parameters evaluated from these measurements can be considered as the elastometric properties of the dental system investigated. The recorded response given by Equation (12) can then be expressed in the sampled form:where are unknown complex conjugate quantities, depending on the damping factors and on the pseudoangular frequencies defined for each DOF similar to Equation (9). Elasticity 7. (ii)To achieve more accurate measurements, the impact response (the “free response”) of the tooth has to contain several components; therefore, a model with n DOFs has to be used. The classical equation of motion of the mass m iswhere is the instantaneous position of the vibrating mass, is its speed, and is its acceleration. (MPa) 0 10 20 30 40 50 60 70 80 % Cold Reduction FIGURE 1 – EFFECT OF COLD WORK ON TENSILE PROPERTIES UTS 0.2% YS Elongation There are no records, to our knowledge, about a mobility evaluation method for teeth placed under a bridge, due to the fact that the behaviour of the teeth is different when they are connected. The differences between the responses of the systems in these two cases are determined with the new method proposed. The results showed that most of the apparent properties for the Sante variety were greater than those of the Marfona variety. The frictional properties of the tubers were affected by the tuber size, the surface type, and the interaction between them. Therefore, only one of these two parameters is enough to complete the analysis. The bunches were subjected to storage tests, and when the physical property tests were performed, each individual fruit was used as a sample (Brix value: 18.75 ± 1.01 °Brix, pH value: 3.69 ± 0.16, diameter: 28.07 ± 2.08 mm, weight: 17.38 ± 2.11 g). The stronger tooth-PDL system thus supports the weaker. The model was able to describe the mobility of the tooth-PDL tissue system with or without a dental bridge/FPP, as well as to complete the evaluation of each dental bridge abutment. Plasticity 6. As pointed out above, there are two ways to describe the properties of this deformable solid, each with a corresponding set of parameters which expresses the physical properties of the system investigated: with more precise rheological models or with a simplified description of these properties with discrete mechanical models with n DOFs. All these parameters are also common for such tests. Cosmin Sinescu also acknowledges the support of the Victor Babes University of Medicine and Pharmacy of Timisoara (Grant PIII-C2-PCFI (2015-2016), DENTALOCT). On the contrary, the tooth is also subjected to constraints that actually reduce its possible motions and its number of DOF. Six bunches were used for the measurements. In further studies, we will investigate the relationships between these properties and nondestructive methods of estimation of mechanical properties using color parameters. The breaking stress did not reflect changes in the mechanical characteristics of samples during storage. Therefore, the storage conditions in this study were 15°C, RH 95% (high-humidity storage: HHS) and 15°C, RH 40% (low-humidity storage: LHS). We focused on breaking points in the compression tests and evaluated several mechanical parameters, namely, breaking force, breaking energy, breaking stress, breaking strain, and breaking elasticity. However, such a simplifying remark cannot be fully made for Kμ (in order to completely eliminate it from the analysis) as this parameter is (Equation (22)) a combination of the parameters υμ and ξμ. Changes in mechanical properties of “Shine Muscat” fruit during storage: (a) breaking stress; (b) breaking strain; (c) breaking elasticity. The storage tests were performed at 15°C under two relative humidity (RH) conditions, i.e., RH 95% and RH 40%. (viii)The modal damping factor ξμ is less relevant for the analysis; as by comparing the values in Tables 1 and 2, some of them increase and some decrease after the FPP is placed—with regard to a different DOF. Error bar shows standard error (, Changes in color properties of “Shine Muscat” fruit during storage: (a) color difference; (b) chroma. Research article 28 Mar 2018. Taking into account the aspects above, we have chosen in the present study not a continuous mechanical model, but the method of the impact response of the tooth with multiple DOFs in order to fulfill the aim of this work, i.e., to provide a more accurate, but also a clinically applicable information on the elastic properties of the tooth-PDL tissue. Because the fruit is distributed after harvest, it is necessary to study the storage characteristics of the fruit to prevent quality decline, such as texture and color; however, flavor and aroma volatile content are the only storage characteristics that have been investigated [3]. Mechanical Properties Plain Galvanized sheets and coils available from BSL, conforming to mechanical properties requirements as per IS 277:2003 (amendment No.4, 2011), are as follows : However, due to their brittleness, the application of CPC implants is limited to non-load bearing areas. These methods are based on the investigation of the function of the frequency response to a harmonic excitation [11]. gov.in.is.277.2003 Identifier-ark ark:/13960/t2z33pn5d Ocr ABBYY FineReader 8.0 Ppi 600 Rights Published under the auspices of the Right to Information Act 2005. plus-circle Add Review. We have introduced a linear mechanical model with several DOFs, consisting of a viscous-damped vibrating system. 1Graduate School, Department of Mechanical Engineering, Jeonju University, KOREA . Wei, Jingjing Ma, Songqi Yue, Hong Wang, Sheng and Zhu, Jin 2018. These results clarified that the weight loss greatly influenced the mechanical and color characteristics of Shine Muscat fruit and the inhibition of weight loss, namely, water loss, was critical to maintain these characteristics after harvest. 2018, Article ID 7258029, 6 pages, 2018. https://doi.org/10.1155/2018/7258029, 1Food Research Institute, NARO, 2-1-12, Kannondai, Tsukuba, Ibaraki 305-8642, Japan, 2Institute of Fruit Tree and Tea Science, NARO, 2-1 Fujimoto, Tsukuba, Ibaraki 305-0852, Japan, 3Graduate School of Horticulture, Chiba University, 648 Matsudo, Chiba 271-8510, Japan. It is well-known that the free response can be written as a combination:where the pairs () or () represent the integration constants. The mechanical and color properties, excluding breaking stress, were correlated with increasing storage duration in LHS and weight loss. Stress was calculated as a ratio of the load to the area of the probe. The cement-aggregate interface is considered an additional phase introduced by the presence of aggregates. The first part (i.e., the 0–2 ms interval) contains the response of the tooth (abutment) during the impact period between the Periotest hammer and the tooth (abutment), followed by the true free response. The mass of the excitation head of the Periotest device is m = 8 g and the time of impact is τ = 0.1 to 0.2 ms, with a repetition frequency of 4 Hz. Hardness 2. Figures 4(a)–4(e) reveal the relationships between weight loss and mechanical or color properties of the sample. You can assign properties such as color and linetype to individual objects, or as default properties assigned to layers. Moreover, we confirmed a strong correlation between the color and mechanical properties, excluding breaking stress, of samples. In all such investigations, a mechanical system with a single degree of freedom (DOF) has been considered; therefore, a single damped oscillator has been used. A nonperturbative measurement method, based on the impact response of the tooth, is further discussed for the estimation of these parameters. The tuber’s size positively affected the physical and mechanical properties of the tubers. For υμ and for Kμ, we have already seen that they have the same behaviour as for the other two DOFs. An advantage of such discrete dynamical models is the fact that the free response of the tooth presents one to several damped harmonic components, corresponding to the one or several DOFs of the system. [10] clarified the influence of humidity on the mechanical and color changes of the strawberry fruit during storage. This study reports on clinical and mathematical studies to determine the constitutive law of the PDL. An experimental method based on the free response analysis was utilized in order to obtain these parameters. 3. Tensile properties of the TiZrHfNbTa alloy at 77K. Weight decrease may influence the mechanical properties of the fruit [11]. Effects of organic matter on mechanical properties of dredged sediments for beneficial use in road construction. Based on these data, we developed equations to estimate the changes in these physical properties from the weight loss data collected during storage. Using a Doppler ultrasound sensor placed on the gingiva in the vicinity of the tooth investigated, this method eliminated the interaction between the exciter and the tooth-PDL tissue system. Mechanical properties, physiological behavior and function of aponeurosis and tendon. In their study, the relative humidity (RH) was controlled at high or low conditions to investigate the influence of storage humidity on the physical properties of the samples. The storage tests were conducted using the FJ-TR-H240 incubator (Fuji Plant, Japan) and a custom incubator (Ebara, Japan). The mechanical strength of metal–organic frameworks (MOFs) is highly relevant for their practical applications. Equation (5) gives n solutions for the n complex conjugate pairs of eigenvalues and eigenvectors , where . The objective of this study was to clarify changes in weight loss, mechanical, and color properties of Shine Muscat fruit during storage and the relationships between them. During hot rolling, events such as work hardening, Still, as pointed out in (viii), Kμ and υμ do have the same trend. Its solution gives the free response (i.e., the response to a Dirac impulse) of the system:where , are the complex quantities. Weight loss was highly correlated with the breaking strain and elasticity, ΔE, and C. In addition, the physical properties could be estimated from weight loss data (R2 = 0.81–0.94). Readers can access the data underlying the findings of the study (please see Figures 4 and 5, as well as Tables 1 and 2). Specifically, if we consider that the tooth is a free rigid body, it has six DOFs corresponding to its six possible independent motions: three translations of the center of mass along the axes (x, y, z) and three rotations around these axes, characterized by the angles (α, β, γ) (Figure 2). [7] and Maury et al. This represents, if m > 2n, an overdetermined system of equations. The signal processing is pointed out in Section 4. Typical sequence of the measured response to the Periotest pulses (where the instantaneous velocity. The PDL is a complex structure which consists of fiber bundles, fluids, cells, and vessels; it displays a time-dependant and force-dependant, nonlinear behaviour. We will be providing unlimited waivers of publication charges for accepted research articles as well as case reports and case series related to COVID-19. Actually, because the tooth is an elastic deformable solid, additional motions exist as a result of its flexural and torsional motions; these motions have been investigated by using FEM on simplified models [21, 22]. Once n is established, the Prony series method is utilized to determine the reduced eigenangulars and the damping factors , where . The sampling frequency is given by . Its impact response measured in a point can be written classically as the linear combination of 2n terms of complex argument exponentials: The modal analysis/structural dynamics provides a series of methods (in time or in the frequency domain) that are able to extract the relevant information concerning the properties of the physical system from the experimental results [28, 29]. From Equation (3), it is possible to obtain the rest of the modal parameters. Nonetheless, the results were limited by simple sensory evaluations, including firmness (high or medium). The biomechanical behaviour of the periodontal ligament (PDL) is still not well understood although this topic has been studied for almost 100 years.
