PURPOSE To compare the accuracy of 2D algorithm with an established 3D algorithm, and to define the number of CT-slices needed for treatment planning of intact breast irradiation. MATERIAL AND METHODS Twenty patients with breast cancer treated with conservative surgery were included in this study, ten of them had right breast cancer and the other 10 patients had cancer of the left breast. For...

A posturally induced "stretch weakness" of the right hip abductor muscles has been reported in many healthy right-handed persons in the literature. The purpose of this study was to test for differences in the maximal isometric hip abduction torque produced between hip sides across multiple hip abduction angles. The torques were measured on 40 healthy right-handed individuals using a specialized...

The asymmetric unit of the title compound, C(15)H(12)Cl(2)N(2)O(2), contains two independent mol-ecules. In both independent mol-ecules, the N-H bond in one of the amide fragments is anti to the meta-chloro group of the adjacent benzene ring and that in the other amide group is syn to the other meta-chloro group. Furthermore, in both mol-ecules, each amide group is almost coplanar with the adja...

A matching cut is a partition of the vertex set graph into two sets and B such that each has at most one neighbor in other side cut. The Matching Cut problem asks whether cut, been intensively studied literature. Motivated by question posed Komusiewicz et al. [Discrete Applied Mathematics, 2020], we introduce natural generalization this problem, which call d -Cut: for positive integer d, d-cut ...

The title compound, C(12)H(13)NO(3), crystallizes with four independent mol-ecules in the asymmetric unit. The N-H bond and the C=O bond in the amide segment are anti to each other. The C=C double bond is cis configured and an intra-molecular O-H⋯O hydrogen bond is formed in each molecule. The mean planes through the aromatic ring and the amide group -NHCO- are inclined at angles of 17.4 (3), 2...

The title compound, C(10)H(8)I(3)NO(4), crystallizes with two mol-ecules in the asymmetric unit. The I atoms and the benzene ring plane in the two mol-ecules are approximately coplanar, the I atoms deviating by -0.1631 (1), 0.0704 (1) and -0.0507 (1) Å from the mean plane of the benzene ring in one mol-ecule and by 0.1500 (1), -0.0034 (1) and -0.1213 (1) Å in the other. The planes of the ester ...

In the title compound, C(29)H(27)Cl(2)N(5)O(2)·C(4)H(8)O, the polycyclic system is composed of three parts: one central pyridine ring substituted by two functionalized pyrazoline rings. The dihedral angles between the central pyridine plane and pyrazoline planes are 5.11 (1) and 13.99 (1)°, whereas the dihedral angles between each chloro-phenyl plane and the attached pyrazoline planes are 88.65...

Bragg’s Law provides a means of explanation when investigating a crystal structure by relating the space between the spheres to the scattering angles of microwaves. This lab explored the phenomenon of Bragg diffraction by looking at the distances between the planes of a three dimensional crystal lattice. Using a microwave emitter, microwave were projected onto the crystal lattice, and then a re...

We describe a modification of Belghiti's liver hanging manoeuvre (LHM) using two small tubes placed in the cut planes, the first between the left lateral and medial sections, and the second along the right hepatic vein, to achieve complete anatomic central hepatectomy for a large tumour compressing surrounding vessels. Using this technique, a large central hepatocellular carcinoma compressing h...
