The application of N, P, K Chemical fertilizers during the time of planting of Black Wattle increases bark thickness and the percentage of moisture that can be retained in the dried condition during tbe fifth year. During the sixth year the applications increase the tannin content. Diameter increase is significant during the third year.

The Lyman Alpha Photometer (LAP), developed for flight on the Mars Orbiter Mission (MOM) spacecraft in 2013, is primarily designed to measure deuterium to hydrogen abundance ratio of the Martian exosphere over a 6-month period from a 263 km × 71,358 km elliptical orbit around Mars. A set of ultrapure (99.999%) hydrogen and deuterium gas-filled cells comprising tungsten filaments, a 25 mm diameter collection lens and a solar-blind photomultiplier tube together with an 8 nm bandpass Lyman alpha filter are the principal electro-optical assemblies of the instrument. This article presents scientific objectives of LAP and its performance specifications along with details of instrument design. The ground characterization techniques to assess LAP operational performance are also presented. End-to-end test results and evaluation matrix of LAP were satisfactory, well within the desired specifications. The first LAP onboard operation was carried out during the cruise phase of MOM spacecraft journey to verify its functionality and all recorded on-board health parameters were satisfactory.Keywords

Background/Objectives: The main objective of this paper is to gather and aggregate data in an efficient manner so that network lifetime is enhanced. Enhanced mechanisms for end-to-end encryption from the sensors to the sink, also termed converge cast traffic, address the concern of reducing both the energy consumption at the sensor nodes and the effect of physical attacks on the nodes. Concealed Data Aggregation provides a good balance between energy-efficiency and security while still allowing data to be processed at the nodes. Methods/Statistical analysis: In this paper, we first outline and discuss the formation of cluster nodes. In these each sensor node is controlled by the Cluster Head (CH) which in turn is controlled by a Base Station (BS). Then, an integrity and authenticity has been enhanced using Mykletun encryption scheme. Findings: To recover, the above issues a novel methodology has been proposed, which provides maximize data integrity and authenticity using Concealed Data Aggregation (CDA). This leads to reduce the transmission overhead and improves the overall lifetime of WSN. Applications/Improvements: We propose a novel approach using homomorphic encryption, Mykletun KeyGen and Boneh Signature Scheme to achieve confidentiality, integrity and availability for secure data aggregation in wireless sensor networks.Keywords

Many of us opt for Credit Cards provided by various banks for the convenience it extends in making purchases on credit with no interest for a limited period and various other offers attached to it. The customer care rendered in giving this service is more or less similar with all the banks. What we take for granted is the various security barriers that the banks employ to protect the customer while making financial transactions. What we are unaware is the quality of these security barriers which we associate with the brand name, reputation and credibility of the bank we choose. No customer knows to what extent the data he gives the bank when filling the application form and other information that the banks emphasize that the customers should keep confidential leaks into the public domain till he / she experiences a breach in the security barriers that is meant to protect the customer. That is when the customer is exposed to the fraudulent transactions in his / her card due to negligence arising from irresponsible conduct by the customer or by the impact of external factors in digital transactions beyond the control of individuals. These are described as cyber crime in digital marketing. This case study is based on the real time experience of Victor (Pseudonym) as a victim of cyber crime in credit card based transactions. The purpose of this case study is to share Victor's experience as a victim of cyber crime and reveal the inadequacies in the electronic financial transactions in India with particular reference to credit / debit card based transactions in digital marketing and expose the attitude of the service provider, namely the concerned bank (Bank X) (identity not revealed), in withdrawing their customer support at such a crucial juncture, thus turning customer care into a customer's nightmare. The steps to be taken by the victim to mitigate the impact of cyber crime has been given in detail as prescribed by the Cyber Crimes Cell. The steps to be taken in seeking relief as recommended by the bank as service provider has been stated under 'Escalation Matrix' in the study. In addition, precautions to be adopted in card based transactions has also been discussed.Keywords
