An Experimental Approach for Developing RFID Ready Receiving and Shipping

Abstract: Radio Frequency Identification (RFID) and related technologies have been touted to allow exponential improvements in supply chain logistics and management. However, many industrial users have indicated that these technologies have not provided the anticipated benefits. The two complimentary strategies required to address the RFID reliability are: to improve the reliability of RFID technology and to design the supply chain infrastructure that enables RFID. The focus of this paper is on designing the supply chain infrastructure to enable RFID by developing guidelines for “RFID Ready Facilities”. These guidelines were developed based on a set of experiments conducted in the RFID supply chain laboratory. These guidelines were developed by using Design of Experiments (DOE) to determine the operational and facility factors that impact RFID reliability. The three different packaging strategies were tested on packages, boxes and their various combinations. The main factors considered in the experiments were the following among many others: Package Orientation (PO), Tag Placement (TP), Package Placement (PP), Reader Location (RL), Box Orientation (BO), Tag Placement on Box (TPB) and Tag Placement on Package (TPP). Based on the DOE results, general guidelines were developed for RFID packaging

Morphological and morphometric study of the subscapular arterial tree with its clinical implications

Background: Knowledge of anatomy of the subscapular arterial tree is very important as it is commonly used for microvascular grafting to substitute injured portions of the arteries of hands and forearm. So, the study aims to examine the subscapular arterial tree and its variants. Aim and Objectives: To observe the subscapular arterial tree and its variants in the origin and branching pattern as well as to locate the distance of origin of subscapular artery and circumflex scapular artery from various anatomical landmarks. Material and Methods: Twenty-six upper limbs were used in the study. The origin and branches of subscapular artery were noted down. Distance between the various anatomical landmarks and the origin of subscapular and circumflex scapular artery were noted down. Variants in the origin and branching pattern were noted. Results: In five limbs, the 2nd part of axillary artery gave rise to subscapular artery. On the right and left side, the mean distance between the origins of subscapular artery from pectoralis minor was 2.92 and 3.17 cm, respectively. In five limbs, subscapular artery was originating along with posterior circumflex humeral artery and in three limbs with lateral thoracic artery. In two limbs, the 3rd part of axillary artery was giving rise to circumflex scapular artery directly. The mean distance of the origin of circumflex scapular artery from pectoralis minor was 3.53 and 3.83 cm away on right and left side, respectively. On both right and left side, the mean distance of the origin of circumflex scapular artery was 2.18 cm away from the origin of subscapular artery. Conclusion: The measurements on the subscapular artery and its variations will help the surgeons in identifying subscapular artery easily for microvascular arterial grafting

An unorthodox innervation of the gluteus maximus muscle and other associated variations: A case report

Knowledge of peripheral nerve morphology, location, and variation is important for facilitating appropriate diagnosis and intervention. We present a unique case of absence of the inferior gluteal nerve and high division of the sciatic nerve. In this instance, the common peroneal nerve was found piercing the piriformis muscle and emerging distally in the form of two trunks: thin medial and thick lateral. The medial trunk presented an interesting course, supplying the gluteus maximus muscle before joining the lateral trunk to form the common peroneal nerve. Additionally, the arteria nervi ischiadisci was also observed accompanying and supplying the tibial nerve passing inferior to the piriformis. These variations are important for clinicians and surgeons for some radiological diagnoses and surgical procedures in the lower limb

Case Report Section: Pathology Pigmented epidermal cyst -A rare case report

ABSTRACT Epidermal cyst is a common benign cystic lesion of skin. These cysts are lined by stratified squamous epithelium. Melanin deposition can be seen in the wall of the cyst to variable extent, but dense collection of melanin is a rare entity. Here we present a case of 24 year old male patient with pigmented epidermal cyst on the back

ansa cervicalis: anatomical variation

The ansa cervicalis is a loop of nerves that is usually formed by the union of ventral rami of spinal nerves C1, C2, and C3. It is located in the carotid triangle of the neck, lying superficial to the carotid sheath. During routine dissection, unilateral variation of the ansa cervicalis was observed. The superior root, arising from hypoglossal nerve, was initially bifurcated and later united to form a single superior root. IN addition, the inferior root consisted of fibres arising from the spinal accessory nerve, C1, C2 and C3 spinal nerves that joined separately. Fibres from the spinal accessory and C1 joined to form a single root. Thus, a ‘triple form’ of ansa cervicalis was observed. An interconnection was observed between the C2 and C3 fibres. Knowledge of such anatomical variations is important for surgery, clinical intervention or trauma involving the carotid triangle or the structures within or deep to this region
