Five cases of spinal leptomeningeal infiltration by systemic cancer are presented and myelographic features are discussed with a review of the literature. Common characteristic features are parallel longitudinal striations due to thickened nerve roots in the cauda equina and bizarre irregular filling defects with varying degrees of blocks, resembling arachnoiditis. Another pattern described in ...

From Definition 1.1, checking a polynomial is separable requires building a splitting field to check the roots are distinct. But we will see in Section 2 a criterion for deciding when a polynomial is separable (that is, has no multiple roots) without having to work in a splitting field. In Section 3 we will define what it means for a field extension to be separable and then prove the primitive ...

The paper describes the anatomical variation of four roots in a mandibular permanent first molar diagnosed using multiple angulated preoperative radiographs and its successful nonsurgical endodontic management. Careful observation and exploration of the pulpal floor using a dental operating microscope revealed a peculiar developmental root fusion line on the pulp chamber floor. Based on the abo...

We present an algorithm for isolating the roots of an arbitrary complex polynomial p that also works for polynomials with multiple roots provided that the number k of distinct roots is given as part of the input. It outputs k pairwise disjoint disks each containing one of the distinct roots of p, and its multiplicity. The algorithm uses approximate factorization as a subroutine. In addition, we...

In vitro budinduction and shoot regeneration of Lantana camara L. was investigated using axillary nodal explants. Multiple shoot buds were induced on Murashige and Skoog (MS) media supplemented with 0, 2, 4 and 8 mg/l of 6-benzylaminopurine (BAP) or thidiazuron (TDZ) for proliferation and 0, 0.25 and 0.5 mg/l indole-3 butyric acid (IBA) for rooting. After 4 weeks, a maximum number of shoot buds...

In this paper, we propose, to the best of our knowledge, first iterative scheme with memory for finding roots whose multiplicity is unknown existing in literature. It improves efficiency a similar procedure without due Schröder and can be considered as seed generate higher order methods characteristics. Once its convergence studied, stability analyzed showing good properties, it compared numeri...

Involvement of the peripheral nervous system is one of the complications of multiple myeloma with a varying incidence of clinical and subclinical neuropathy in different studies. As most of the patients with multiple myeloma suffer from generalized systemic symptoms such as malaise, bone and low back pain, the clinical clues to the diagnosis of the neuropathy in its initial stages could be ...

Background: Dentin dysplasia (DD) is a rare disturbance of dentin formation, characterized by normal enamel but atypical dentin formation with abnormal pulpal morphology. In DD type I, the teeth appear clinically normal in morphologic appearance and color. Radiographic analysis shows obliteration of all pulp chambers as well as short, blunted, and malformed or absent roots with multiple periapi...
