Then 12 research papers report on such matters as the Alexander module of a trigonal curve, fibered links of singularities of polar weighted homogeneous mixed polynomials, classes in the classification of curves on rational surfaces with respect to logarithmic pluri-genera, computing algebraic local cohomology classes associated with semi-quasihomogeneous singularities, some geometric-arithmetic aspects of separated variable curves, and mirror symmetry between orbifold projective lines and cusp singularities.

Rane A et al (7) stated that dysuria, which was reported by 36.7% patients in their study is usually experienced at the end of voiding, and is secondary to trigonal irritation by the distal end of the stent when it crosses the midline or forms an incomplete loop.
In particular, depending on the crystallization conditions and molecular characteristics, different packing structures of the PP helices lead to the formation of the four well-known crystal forms: monoclinic ([alpha]), trigonal ([beta]), triclinic ([gamma]), and smectic ([delta]) structure [1, 2].
