Gantry structure has the advantages of easy production, high bearing capacity, stability and so on. It is widely used in engineering. There is an optimal solution for different structural parameters in gantry. In the practical engineering application, the safety factor is higher, which can meet the load demand, and the weight is less. In this paper, the advantages and disadvantages of the colum...

We propose a simple mechanism capable of achieving international agreement on averting the threat of global warming. It employs a contest creating incentives among participating nations to exert both efficient productive efforts and efficient emissions reductive efforts. Participation in the scheme is voluntary and turns out to be individually rational if the alternative is no agreement at all....

Preserved ejection fraction heart failure (HFpEF) diagnosis remains controversial, and invasive left ventricular (LV) hemodynamic evaluation and/or exercise testing is advocated by many. The stiffer HFpEF myocardium may show impaired stroke volume (SV) variation induced by fluctuating LV filling pressure during ventilation. Our aim was to investigate spectral transfer function (STF) gain from e...

Nowadays in highly competitive precision industries, the micromachining of advanced engineering materials is extremely demand as it has extensive application in the fields of automobile, electronic, biomedical and aerospace engineering. The present work addresses the modeling and optimization study on dimensional deviations of square-shaped microgroove in laser micromachining of aluminum oxide ...

In the Edge-Disjoint Paths with Congestion problem (EDPwC), we are given an undirected n-vertex graph G, a collection M = {(s1, t1), . . . , (sk, tk)} of demand pairs and an integer c. The goal is to connect the maximum possible number of the demand pairs by paths, so that the maximum edge congestion the number of paths sharing any edge is bounded by c. When the maximum allowed congestion is c ...

The effects of multiple doses of estradiol dipropionate (EDP) or calcium glucoheptonate (Ca) on the growth and function of pituitary somatotropes (GH cells) were studied. Female middle-aged rats were receiving i.p. EDP (0.625 mg i.p./kg b.w.), or Ca (11.4 mg/kg b.w) every day for two weeks. Blood samples were collected for hormone analyses and pituitaries dissected for histological and morphome...

In patients with technically adequate selective coronary arteriograms and left , ventriculograms, a scoring system was used to grade the severity of coronary obstruction from 0 (no disease) to 15 (total obstruction of all three major coronary arteries). The median score in 75 consecutive cases was 10. Three hemdynamic measurements were examined in these patients; left ventricular end-diastolic ...
