The use of Wireless Sensor Network (WSN) with IP network in Precission Agriculture (PA) would be an added advantage to existing solutions of PA system. However, existing WSN Technologies, such as Zigbee and other legacy sensor networks are originally design for non IP-based WSN. Hence, they have difficulties in constructing global infrastructure for the(More)
Wireless sensor network is one of the emerging technologies which will have impact on our daily life in near future. This paper presents a 6LoWPAN communicator, which is a mobile device system and responsible for bi-directional communication to retrieve sensor data and conFig sensor nodes. This paper discusses about the overall system and communication(More)
The low power wireless sensor devices which usually uses the low power wireless private area network (IEEE 802.15.4) standard are being widely deployed for various purposes and in different scenarios. IPv6 low power wireless private area network (6LoWPAN) was adopted as part of the IETF standard for the wireless sensor devices so that it will become an open(More)
Spontaneous coronary artery dissection is a very rare cause of acute coronary syndromes and can be life threatening given the rarity of the condition. It should be part of differentials in young females presenting with acute coronary syndromes without routine risk factors for coronary artery disease, especially before, during, and after pregnancy. It is(More)

Hepatitis associated aplastic anemia (HAAA) is a rare syndrome in which severe aplastic anemia (SAA) complicates the recovery of acute hepatitis (AH). HAAA is described to occur with AH caused by viral infections and also with idiopathic cases of AH and no clear etiology of liver injury. Clinically, AH can be mild to fulminant and transient to persistent(More)
