Morphological Analysis of the Human Internal Iliac Artery in South Indian Population
Objectives: The accidental hemorrhage is common due to erroneous interpretation of the variant arteries during surgical procedures, hence the present study has been undertaken with reference to its morphological significance. The objectives were to examine the level of origin, length and the branching pattern of the human internal iliac artery in South Indian population. Methods: The study included 60 human bisected pelvises irrespective of their side and sex. The specimens were collected from the anatomy laboratory and were fixed with the formalin. The branching patterns were studied and demonstrated as per the guidelines of Adachi. Results: The origin of internal iliac artery was at the level of S1 vertebra in majority (58.3%) of the cases. The average length of internal iliac artery was 37 ± 4.62 mm (range, 13-54 mm). The type I pattern of the internal iliac artery was most common (83.5%) followed by types III and II. The type IV and V pattern of adachi were not observed. Conclusions: The results of this study were different from those reported by others and may be because of racial and geographical variations. Prior knowledge of the anatomical variations is beneficial for the vascular surgeons ligating the internal iliac artery or its branches and the radiologists interpreting angiograms of the pelvic region
Power Generation System by using Piezo Sensors for Multiple Applications
Generally there is huge demand for power production. So going for alternative energy source is the best way to harvest electricity. We have proposed that piezo sensors produce electricity when pressure is applied on them. These sensors are then connected in series and parallel combination and placed in a tile like structure. This tile can be used in any place wherever pressure is applied. The harvested power can be stored in a battery and used for AC or DC loads and also voltage generated by a single tile can be displayed on display devices like LCD located at a different location using zigbee technology for smart analysis.

Yoga Reduces Symptoms of Distress in Tsunami Survivors in the Andaman Islands
A month after the December 2004 tsunami the effect of a 1 week yoga program was evaluated on self rated fear, anxiety, sadness and disturbed sleep in 47 survivors in the Andaman Islands. Polygraph recordings of the heart rate, breath rate and skin resistance were also made. Among the 47 people, 31 were settlers from the mainland (i.e. India, ML group) and 16 were endogenous people (EP group). There was a significant decrease in self rated fear, anxiety, sadness and disturbed sleep in both groups, and in the heart and breath rate in the ML group, and in the breath rate alone in the EP group, following yoga (P < 0.05, t-test). This suggests that yoga practice may be useful in the management of stress following a natural disaster in people with widely differing social, cultural and spiritual beliefs
QoS Constrained Optimal Sink and Relay Placement in Planned Wireless Sensor Networks
We are given a set of sensors at given locations, a set of potential
locations for placing base stations (BSs, or sinks), and another set of
potential locations for placing wireless relay nodes. There is a cost for
placing a BS and a cost for placing a relay. The problem we consider is to
select a set of BS locations, a set of relay locations, and an association of
sensor nodes with the selected BS locations, so that number of hops in the path
from each sensor to its BS is bounded by hmax, and among all such feasible
networks, the cost of the selected network is the minimum. The hop count bound
suffices to ensure a certain probability of the data being delivered to the BS
within a given maximum delay under a light traffic model. We observe that the
problem is NP-Hard, and is hard to even approximate within a constant factor.
For this problem, we propose a polynomial time approximation algorithm
(SmartSelect) based on a relay placement algorithm proposed in our earlier
work, along with a modification of the greedy algorithm for weighted set cover.
We have analyzed the worst case approximation guarantee for this algorithm. We
have also proposed a polynomial time heuristic to improve upon the solution
provided by SmartSelect. Our numerical results demonstrate that the algorithms
provide good quality solutions using very little computation time in various
randomly generated network scenarios

Comparative Analysis of QoS-Aware Routing Protocols for Wireless Sensor Networks
The main ability of wireless sensor networks (WSNs) is communicating and sensing between nodes, which are deployed in a wide area with a large number of nodes. Wireless sensor networks are composed of a large number of sensor nodes with limited energy resources. One critical issue in wireless sensor networks is how to gather sensed information in an energy efficient way, since their energy is limited. The limiting factors of the sensor nodes, such as their finite energy supplies and their moderate processing abilities, as well as the unreliable wireless medium restrict the performance of wireless sensor networks While contemporary best-effort routing approaches address unconstrained traffic, QoS routing is usually performed through resource reservation in a connection-oriented communication in order to meet the QoS requirements for each individual connection. This article surveys a sample of existing QoS-Aware Routing Protocols for Wireless Sensor Networks and highlights their key features, including merits and limitations. Keywords: Wireless sensor networks, Routing protocols, QoS-Aware Routing Protocols
Microbiological Hazard Identification and Exposure Assessment of Poultry Products Sold in Various Localities of Hyderabad, India
A study was carried out to identify microbiological hazards and assess their exposure associated with consumption of poultry based street food served in different localities of Hyderabad. The study indicated that chicken 65, chicken fried rice, chicken noodles, chicken Manchuria and chilly chicken are the most common recipes. A process flow diagram was developed to identify critical control points in the food item. After analysis of the samples at each level of preparation, it was observed that rice and noodles were kept at room temperature for about 5-6 hrs which was a critical control point. A total of 376 samples including chicken fried rice, chicken noodles, boiled noodles and boiled rice were collected from circle 1, 2, 3, 4, 5, 6, and 7 of Greater Hyderabad municipal corporation (GHMC) and analyzed for microbiological examination. The most prevalent pathogenic bacteria isolated were S. aureus (3.4 log 10 cfu/g) and B. cereus (3.4 log 10 cfu/g). Salmonella spp. was present in salads (3.2 log 10 cfu/g) and hand washings of the food handler (3.5 log 10 cfu/g). Salmonella contamination was found in salads served along with chicken fried rice and chicken noodles than in the food
Demographic profile and functional outcome following fixation of malleolar fractures in adults
Background: Malleolus are important structures which forms part of ankle mortise and provide stability to it. This article underlines the current demographic profile of patients sustaining malleolar fractures in adults. It also discusses the modalities of treatment and functional outcomes following open reduction and internal fixation of these fractures as well as the improvement in functional outcome following early mobilization.Methods: 30 patients sustaining malleolar fractures who attended the Department of Orthopedics were included in the study. The patients were operated as and when the soft tissue condition permitted and were followed up in outpatient department at 6 weeks, 3 months and 6 months where functional outcome based on Baird and Jackson scoring system was assessed.Results: In this study, the average age of patients was 43.8 years with a male preponderance. Supination-external rotation was the most common mechanism of injury following a slip or twisting injury. According to Baird and Jackson scoring system 20% patients had excellent, 50% patients had good results, 20% patients had fair results and 10% patients had poor results.Conclusions: 70% patients had excellent to good results following fixation of malleolar fractures. Early mobilization was started in 5 patients with 80% patients showing excellent results. Open reduction and Internal fixation proved to be an excellent procedure leading to union in all cases, less complication and early resumption of routine activities.
