"The effect of gravity on the evolution of life on earth based on general relativity and the low of free fall "

The radius of the universe can be determined by combining the Einstein formulas, which determine the degree of gravitational redshift and describe the angle of refraction of a beam of light running along celestial bodies. The relationship between the two equations is made by the ratio of the total angle to the angle of deflection of the beam of light passing by the Earth according to the rules of Euclidean geometry (2∙π/α). The so-called Darwinian evolutionary distances measured from the color changes of the respiratory pigments of biological creatures (in connection with the phase of their circulation) can be paralleled with this. It is possible to measure these to the radius of the universe determined in this way. During the nearly 4-billion-year uninterrupted process of Darwinian evolution, living organisms presumably adapted to surface gravity during mutations as well as to any other environmental factor. In this way, they can accelerate continuously along the imaginary straight line from the origin of life to the appearance of the human race, i.e., within the short evolutionary distance, due to the attractive effect of gravity. During the free fall from the past to the present, the curvature of space-time may gradually appear in their physiological processes and anatomical structure. Specifically in their circulatory system, the rate of evolution would correspond to the most qualitatively advanced level, i.e., the velocity of human blood circulation. In this way, the evolution accelerating to almost the speed of light is reduced to 5.23 cm/s due to an enormous time dilation (as a proportion of angles; α/2/π). With this average human blood flow velocity, together with data from cardiac and circulatory procedures, a toroidal, or even more refined, ‘interlocking figure 8 model’ can be constructed. It reflects the dimensions, flow and pressure conditions of the pulmonary and systemic circulation, as well as the work of the heart.

3D-printing analysis of surface finish

Abstract 3D printing is a process of producing 3D objects from CAD model. Using additive processes, 3D printing is done where a part is formed layer by layer. A melted affidavit model conveying ordinary surface examples with various element sizes and angle proportions will be produced on a FDM framework with various form directions. The surface finish of each 3D printed part will be inspected. The objective is to evaluate surface finish of different parts by changing the layer thickness and other parameters such as infill, infill pattern, roof thickness, floor thickness, and number of shells were considered for the study of build time optimization and also find out the relation between surface roughness and layer thickness.

Changes in overall ventricular myocardial architecture in the setting of a porcine animal model of right ventricular dilation

BackgroundChronic pulmonary regurgitation often leads to myocardial dysfunction and heart failure. It is not fully known why secondary hypertrophy cannot fully protect against the increase in wall stress brought about by the increased end-diastolic volume in ventricular dilation. It has been assumed that mural architecture is not deranged in this situation, but we hypothesised that there might be a change in the pattern of orientation of the aggregations of cardiomyocytes, which would contribute to contractile impairment.MethodsWe created pulmonary valvular regurgitation by open chest, surgical suturing of its leaflets in seven piglets, performing sham operations in seven control animals. Using cardiovascular magnetic resonance imaging after 12 weeks of recovery, we demonstrated significantly increased right ventricular volumes in the test group. After sacrifice, diffusion tensor imaging of their hearts permitted measurement of the orientation of the cardiomyocytes.ResultsThe helical angles in the right ventricle approached a more circumferential orientation in the setting of right ventricular RV dilation (p = 0.007), with an increased proportion of surface-parallel cardiomyocytes. In contrast, this proportion decreased in the left ventricle. Also in the left ventricle a higher proportion of E3 angles with a value around zero was found, and conversely a lower proportion of angles was found with a numerical higher value. In the dilated right ventricle the proportion of E3 angles around −90° is increased, while the proportion around 90° is decreased.ConclusionContrary to traditional views, there is a change in the orientation of both the left ventricular and right ventricular cardiomyocytes subsequent to right ventricular dilation. This will change their direction of contraction and hinder the achievement of normalisation of cardiomyocytic strain, affecting overall contractility. We suggest that the aetiology of the cardiac failure induced by right vetricular dilation may be partly explained by morphological changes in the myocardium itself.
