objectives this study aimed to examine the relationship between patients’ anthropometric characteristics and depth of spinal needle insertion to the subarachnoid cavity. patients and methods 385 patients with asa class i – ii, aged 18 - 65 years and undergoing elective surgery of the lower abdomen and extremities under spinal anesthesia, were selected for this cross-sectional study. the patient...

Objectives: Dry Needling (DN) is a novel and effective intervention for patients with Myofascial Pain Syndrome (MPS). Some characteristics, such as needle penetration depth, needle insertion into the target muscle, and trigger points must be identified in this intervention. The Ultrasound (US)-guided DN is a technique that involves needle insertion at the site of injury and the simulation of ti...

We study some poset structures on the set of all compositions. In the first case, the covering relation consists of inserting a part of size one to the left or to the right, or increasing the size of some part by one. The resulting poset N was studied by the author in [5] in relation to non-commutative term orders, and then in [6], where some results about generating functions for standard path...

Cuckoo hashing is an efficient technique for creating large hash tables with high space utilization and guaranteed constant access times. There, each item can be placed in a location given by any one out of k different hash functions. In this paper we investigate the random walk heuristic for inserting in an online fashion new items into the hash table. Provided that k ≥ 3 and that the number o...
