Study on the prediction technology of the retreaded tire residual life

Field: Engineering (Physical Sciences)

In view of the aging phenomena, a test system was established to forecast the residual life of the retreaded tire matrix based on the finite element simulation and performance tests of the loading-bearing capacity for the retreaded tire. The method was discussed to design and identify the safety factor of the matrix residual life. It can be achieved about life forecast of the tire carcass in establishing the compound material laminated structure model of load-vehicle retreaded radial tire, the finite element simulation analysis model and testing methods, and in simulating and identifying the used matrix remaining life factor of safety, and in setting up the stiffness coefficient database of the new tire of the same brand, type and specification under the standard load and tire pressure conditions. The method proposed in this paper can predict the residual life of old tire matrix without being renovated and identify whether the retreaded value of old tire or not, which bring a scientific basis for tire rethreaded companies when choosing old tire matrix; and moreover it can forecast the residual life of retreaded tire in view of the different matrix aging, which provides the effective method for the residual life appraisal and prediction of retreaded tire; and then it can present the actual service time and the real use situation that aren't obtained by tire retreaded companies, and determine the safety coefficient of the residual tire life scientifically. And moreover, the 11.00R22.5 retreaded tire was adopted to verify the effect of prediction method. The result indicts that the method is practical and feasible, which provides a theoretical reference in predicting the life of the retreaded tire matrix.

Other problems identified by the farmers werehigh cost of agro-chemicals and pest management.
Epidemiology of cervical cancer in elderly women: Analysis of incidence, treatment, and survival using German registry data

Field: Medicine (Health Sciences)

Abstract Background Cervical cancer (CC) screening is generally recommended until age 65. The incidence of CC could be underestimated, particularly in older women, due to a lack of hysterectomy correction. Furthermore, elderly women (≥65 years) are more often diagnosed with late‐stage disease and have worse outcomes than younger patients. This study aims to provide an in‐depth overview of CC in Germany. Methods Incidence rates of CC (ICD‐10 C53) were determined using data from the German Centre of Cancer Registry data (ZfKD) of six federal state registries. Incidence was corrected by using hysterectomy prevalence values from a real‐world study. The distribution of treatment modalities (surgery, chemotherapy, radiation therapy) was assessed. Relative survival was calculated using the period approach (2011–2015). Survival was stratified by tumor (T) stage and histological type. Results In total, 14,528 CC cases were included, 27.6% of which occurred in elderly women. Cumulative (2001–2015) age‐standardized incidence rates were 12.5 per 100,000 women without hysterectomy correction and 15.5 per 100,000 women after hysterectomy correction (+24% relative change). A lower proportion of elderly women were treated, especially in advanced tumor stages. Younger women (20–64 years) had a higher 5‐year relative survival compared to elderly women: 76.7% versus 46.9%, respectively. Survival was worse with increasing stage and for glandular histological subgroups, particularly among elderly women. Conclusions CC incidence in elderly women is underestimated and survival is lower compared to younger women in Germany. Due to the high disease burden in elderly women, screening and treatment strategies need to be improved.

Experimental measurements of dynamic control surface effectiveness

Field: Engineering (Physical Sciences)

This article reports on a low Reynolds number experimental study of the unsteady lift characteristics of an NACA 0009 airfoil pitched about its midchord, equipped with a 27% trailing-edge flap that could be independently deflected. The airfoil normal force, obtained from integrated surface pressure measurements, was captured during rapid, trailing-edge flap-only deflections; rapid, arbitrary, pitch-only excursions; and combined rapid pitch and flap-deflection motions. The measured aerodynamic response of the flapped airfoil to the various flap, airfoil, and airfoil flap combination motions was compared to theoretical and panel-code-computed aerodynamic-response predictions. These comparisons, and the results of flow visualization experiments, led to the observation that both the flap's effectiveness and the airfoil's lift-curve slope were higher during their motion than their steady-state values, and essentially matched their inviscid theoretical values.
Three’s Company: Two or More Unrelated Receptors Pair with the Same Ligand

Field: Biochemistry, Genetics and Molecular Biology (Life Sciences)

Abstract Intercellular communication relies on signal transduction mediated by extracellular ligands and their receptors. Although the ligand-receptor interaction is usually a two-player event, there are selective examples of one polypeptide ligand interacting with more than one phylogenetically unrelated receptor. Likewise, a few receptors interact with more than one polypeptide ligand, and sometimes with more than one coreceptor, likely through an interlocking of unique protein domains. Phylogenetic analyses suggest that for certain triumvirates, the matching events could have taken place at different evolutionary times. In contrast to a few polypeptide ligands interacting with more than one receptor, we found that many small nonpeptide ligands have been paired with two or more plasma membrane receptors, nuclear receptors, or channels. The observation that many small ligands are paired with more than one receptor type highlights the utilitarian use of a limited number of cellular components during metazoan evolution. These conserved ligands are ubiquitous cell metabolites likely favored by natural selection to establish novel regulatory networks. They likely possess structural features useful for designing agonistic and antagonistic drugs to target diverse receptors.

Indeterminacy in-decisions – science, policy and politics in the BSE (Bovine Spongiform Encephalopathy) crisis

Field: Social Sciences (Social Sciences)

This chapter aims to use an empirical engagement with Bovine Spongiform Encephalopathy-related scientific and policy practices, along with insights from non-human geographies, science studies and poststructuralism to suggest that old certainties and resolutions are misplaced. It demonstrates that the failure to take up the lessons from non human geographies has had and continues to have serious consequences. The chapter also demonstrates that the geographical 'postmodern and cultural turns' offer significant potential for re-engagement with political and policy practices. In 1997, the British government's Chief Scientific Advisor, Robert May, drafted a paper entitled 'The use of scientific advice in policy making'. One of the characteristic features of policy and media debate throughout has been the legitimacy and relevance of scientific advice on the disease. The policy depended upon a multitude of decisions over what and where did and what and where did not matter.
Comparison of serum fructosamine and glycated hemoglobin values for assessment of glycemic control in dogs with diabetes mellitus

Field: Veterinary (Health Sciences)

Abstract OBJECTIVE To evaluate the performance of 2 assays for measurement of serum fructosamine (SF) and glycated hemoglobin (HbA1c) values in dogs and to compare the usefulness of the 2 glycated proteins for assessment of glycemic control in dogs with diabetes mellitus (DM). SAMPLE Blood samples from 40 healthy dogs, 13 diabetic dogs, and 23 anemic normoglycemic nondiabetic dogs and results of 200 assessments of glycemic control in 46 diabetic dogs. PROCEDURES Colorimetric and immunoturbidimetric methods were used for measurement of SF and HbA1c values, respectively. Linearity and precision were determined. The usefulness of SF and HbA1c values for assessment of glycemic control was evaluated with a clinical scoring method used as the reference standard. Cutoff values obtained from receiver operating characteristic curves were used to identify the percentage of dogs correctly categorized by means of SF and HbA1c values. RESULTS Mean intra-assay and interassay coefficients of variation were 3.8% and 2.5%, respectively, for the SF assay, and 1.2% and 1.8%, respectively, for the HbA1c assay. Excellent linearity ( R 2 > 0.99) was obtained for both assays. Values for SF and HbA1c were inversely correlated ( r = −0.40 and −0.33, respectively) with clinical score and correctly indicated glycemic control in 99 of 200 (50%) and 88 of 200 (44%) assessments, respectively. CONCLUSIONS AND CLINICAL RELEVANCE The SF and HbA1c assays were precise, had good linearity, and appeared to be suitable for routine use in veterinary medicine. However, they performed poorly for classifying glycemic control in diabetic dogs.
Maximum likelihood synchronization for OFDM using a pilot symbol: analysis

Field: Computer Science (Physical Sciences)

A performance analysis of algorithms for maximum likelihood estimation of channel parameters for orthogonal frequency-division multiplexing packet detection and synchronization is presented. The detection and synchronization algorithms, which are based on the use of a pilot symbol, are described in Coulson (2001). The performance analyses concentrate on operation in additive white Gaussian noise channels, and the accuracy of these analyses are demonstrated using experimental and simulation data. Methods to extend these analyses to frequency flat multipath fading channels are presented.
Criteria identification to select early thinning treatments in Pinus nigra ssp. laricio Arn. stands in the Basque Country

Field: Agricultural and Biological Sciences (Life Sciences)

The main objective of this study was to identify the best thinning treatment for young Pinus nigra ssp. laricio Arn. stands in the Basque Country. Felling selection criteria qould be based on individual tree attributes and vertical stratification. Data collected in the field indicate that the stands to do not show a tendency to vertical stratification. Individual tree characteristics are not distinctive enough to support felling decisions. Consequently, only operational aspects should be considered when planning treatments in young stands. Low thinning should be preferred over selective thinning at this stage of development in the stands.
Action-Angle formalism for extreme mass ratio inspirals in Kerr spacetime

Field: Physics and Astronomy (Physical Sciences)

We introduce an action-angle formalism for bounded geodesic motion in Kerr black hole spacetime using canonical perturbation theory. Namely, we employ a Lie series technique to produce a series of canonical transformations on a Hamiltonian function describing geodesic motion in Kerr background written in Boyer-Lindquist coordinates to a Hamiltonian system written in action-angle variables. This technique allows us to produce a closed-form invertible relation between the Boyer-Lindquist variables and the action-angle ones, while it generates in analytical closed form all the characteristic functions of the system as well. The expressed in the action-angle variable Hamiltonian system is employed to model an extreme mass ratio inspiral (EMRI), i.e. a binary system where a stellar compact object inspirals into a supermassive black hole due to gravitational radiation reaction. We consider the adiabatic evolution of an EMRI, for which the energy and angular momentum fluxes are computed by solving the Teukolsky equation in the frequency domain. To achieve this a new Teukolsky equation solver code was developed.
The outcomes of gonadotropins releasing hormone (GnRH) antagonist cycles with and without letrozole co-treatment in patients undergoing ICSI

Field: Medicine (Health Sciences)

Background: Letrozole is an aromatase inhibitor which has been proposed as a great tool in ovulation induction and infertility management. This study aimed to evaluate whether the use of letrozole in combination with gonadotropins and GnRH antagonist is superior to gonadotropins and GnRH antagonist alone in women undergoing ICSI treatment. Methods: This prospective randomized controlled trial was conducted during the period from October 2017 to March 2020 in a private fertility center. 112 participants were randomly allocated into two groups either intervention (Letrozole plus antagonist protocol) or control (antagonist protocol) groups. Participants were subjected to ovarian stimulation (OS) using a GnRH antagonist protocol. Only for the intervention group, letrozole was added from the second day of the cycle to the sixth day. On the day of hCG trigger, endometrial thickness, estradiol and progesterone level were assessed. The results were correlated to the outcomes of the Intracytoplasmic sperm injection (ICSI) cycle. Results: Both the intervention and control groups were balanced in respect to the demographic and clinical characteristics. The stimulation outcomes were comparable between the two studied groups. The clinical pregnancy rate and the ongoing pregnancy rate were comparable between both groups. There was no significant relation between the day of embryo transfer and either occurrence of clinical pregnancy or ongoing pregnancy among both groups' participants. Conclusions: Letrozole co-treatment in the first five days of gonadotropins stimulation in anatagonist cycles did not show any significant change in the pregnancy outcomes of ICSI cycles.
Effects of Parathyroid Hormone and Related Polypeptides on the Heart and Coronary Circulation of Dogs

Field: Pharmacology, Toxicology and Pharmaceutics (Life Sciences)

The effects of parathyroid hormone and related polypeptides on the heart were examined using the canine heart-lung preparation supported by a donor. Synthetic bovine parathyroid hormone (PTH) containing 34 amino acids [PTH-(1--34)] and natural bovine PTH containing 84 amino acids [PTH-(1--84)] showed slight positive chronotropic and inotropic action and prominent coronary vasodilator action. The effects of the two compounds were very similar. The cardiac stimulatory action was not blocked by pindolol. The coronary vasodilation occurred without increase in the myocardial oxygen consumption, suggesting that it is due to a direct action on the coronary vasculature. All effects occurred soon after intra-arterial injection, lasted only about 20 min, and were not accompanied by changes in plasma Ca and Pi levels. Fragments of PTH, PTH-(24--34) containing 11 amino acids. PTH-(24--28) containing 5 amino acids, and PTH-(25--27) containing 3 amino acids showed very weak transient coronary dilatory action without cardiac stimulatory effects.

Free vibration of axisymmetrical solid bodies with meridionally varying profile

Field: Engineering (Physical Sciences)

An analysis is presented for the three-dimensional vibration problem of determining the natural frequencies and the mode shapes of axisymmetrical solid bodies, with meridionally varying profiles, expressed as an arbitrary function. For this purpose, the body is transformed into a circular cylinder with unit axial length and unit radius, by a transformation of variables. With the displacements of the transformed cylinder assumed in the forms of algebraic polynomials, the dynamical energies of the cylinder are evaluated, and the frequency equation is derived by the Ritz method. This method is applied to barrel or hourglass-type bodies and frustums of cone, under two combinations of boundary conditions at the ends, and the natural frequencies and the mode shapes are calculated, numerically giving the results.
Early results of subcutaneous mastectomy with immediate silicone prosthetic implant for carcinoma of the breast

Field: Medicine (Health Sciences)

Abstract Surgery for carcinoma of the breast is becoming less radical even to the extent of breast conservation. Subcutaneous mastectomy and implant offers itself as an alternative, retaining a breast shape and removing almost all breast tissue. Forty-four consecutive patients who had this procedure for breast carcinoma were studied with a follow-up of 5–44 months (mean 25·3 months). Only 4 patients (9 per cent) had local recurrences, i.e. recurrence in the skin flap or scar. This compares favourably with other series and other forms of treatment. Removal of the prosthesis was necessary in 10 patients due to local factors. The cosmetic result as assessed by the patients was almost universally pleasing. Twenty-six of 27 patients with prostheses in situ who were interviewed in person or by postal questionnaire were pleased with the results of their surgery. The absence of high recurrence rates locally and high patient acceptance makes this a definite surgical alternative.

The sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) were calculated for each group. Results: The diagnostic specifications of groups A, B, and C, respectively, were found as follows; sensitivity was 95.6%, 80.6%, and 87.1%, the specificity was 51.9%, 58.7%, and 37.8%, PPV was 36.6%, 52.7%, and 37%, and also NPV was 97.6%, 84.4%, and 87.5%, respectively. It was also found fair agreement between iQ200 Workstation and culture results in groups A (P<0.001, ?=0.278), and B (P<0.001, ?=0.353), and also slight agreement in group C (P<0.05, ?=0.179). Conclusion: Our study showed that agreement was highest in the analysis group which including ASP parameter. Addition of ASP to test combination apparently increased the diagnostic value of auto particle recognition software. Full Text: PDF DOI: 10.15640/jcb.v2n2a9
Multi-objective optimal temperature control for Organic Rankine Cycle systems

Field: Energy (Physical Sciences)

The Organic Rankine Cycle (ORC) has attracted a lot of interests for its ability to recover low-grade heat and the possibility to be implemented in decentralized low-capacity power plants. In this paper, a new optimal temperature control method is proposed for ORC systems with non-Gaussian disturbances which influence the quality of exhaust gas. The objective here is to control the speed of the pump so that the superheated vapor temperature follows a target one. It means that the error between those two temperatures is minimized both in magnitude and randomness, which are characterized by mean value and entropy, respectively. Therefore, the proposed control strategy is regarded as a multi-objective optimization problem. To solve this problem, a Multi-Objective Estimation of Distribution Algorithm (MOEDA) is adopted to obtain all the possible optimal control inputs. Simulation results show the effectiveness of the proposed technique.
