A Pink pigmented facultative Methylotrophic bacterium was isolated from the phyllosphere region of cotton by leaf imprinting method on Ammonium mineral salt agar supplemented with 0.5% of methanol and cyclohexamide. Their distinctive pink pigmentation is due to carotenoid, which render them to be tolerant to extreme light condition and radiation. The isolate was morphologically and biochemically characterized and identified as a member of the genus Methylobacterium. The parameters such as temperature, pH, and carbon source were optimized for the extraction of pigment from PPFM bacteria. The optimum pH for growth and pigment production was around 7.5 at temperature of 25 ° C with 0.5% of methanol. The PPFM bacterium was mass multiplied at these optimum conditions, pigment was extracted, and the sample was analyzed by UV- visible Spectrophotometer.

In the recent years many problems are emerging due to the aircraft noise on the airport surrounding areas. The solution to this problem is not easy considering that the neighbourhood asks for the reduction of the number of aircraft operations and the airlines ask for a growing demand in the number of operations in the major airports. So the airport and regulatory authorities try to get a solution imposing a fine to the aircraft which its actual trajectory differs from the nominal one more than a lateral deviation. But, which is the value of this deviation?. The current situation is that many operators have to pay a lot of money for exceeding a deviation which has been established without operational criteria. This paper presents the results of a research program which is being carried out by the authors which aims to determine the "delta" deviation to be used for this purpose. In addition it is proposed a customized method per SID and per airport to be used for determining the maximum allowed lateral deviation by which if the aircraft is within it, then none fine will be imposed. The paper will also explain the current criteria used to design and publish the SIDs and will show the results of the performed assessment for determining the deviation of different aircraft families flying the same departure procedure in an airport aiming to define a current deviation value considering operational factors such airfield elevation, temperature, wind, SID design, etc. And last, the method for determining the allowed lateral deviation without any penalty consists in the computation of a set of templates per aircraft family/SID/airport, in such a way that a particular deviation could be compared against the corresponding template. When the trajectory to be assessed is within the selected template limits, it will mean none penalty should be imposed.

The 'Rajapuri' (AAB) banana cultivar is very popular in Belgaum and Bagalkot districts of Karnataka. However, in recent years its cultivation decreased due to rapid spread of Sigatoka leaf spot disease through sucker propagation. Availability of tissue culture multiplied plant is very scarce as it is highly recalcitrant to tissue culture. The present investigation was undertaken to enhance shoot proliferation using TDZ. Shoot tip explants derived from sword suckers were inoculated on MS medium supplemented with different concentrations of Thidiazuron [TDZ (0.2 and 0.3 mg/L)], 6-Benzylaminopurine [BAP (2.0 and 5.0 mg/L)] and Naphthalene acetic acid [NAA (0.2 mg/L)] alone or in combinations. Cultures were incubated at 25±3°C with a 16 hour photoperiod (2000 lux) provided by cool white florescent tubes. Among the all treatments TDZ 0.2 mg/L produced the maximum number of shoots (3.04) and number of adventitious buds (2.67) per explants as compared to BAP.

A field experiment was conducted during 2008 to 2009 in naturally poly house. Selected chemical and physical characteristics of four types of growing medias comprising of coirpith, perlite, vermiculite and peat as separately and combination with vermicompost as 50% on volume basis ((v/v) were determined and their suitability as growing media was tested using beet root (nobol). Data on pH, EC, nutrient contents and various aspects of air-water relationships of the media, as well as yield of beet root were collected. The root yield per treatment was not significantly influenced by the treatments T1' T2, T3 and T4 but while root yield of beet root was found to be significantly influenced by treatments T5, T6, T7 and T8. Results indicated that certain chemical and physical properties of selected soilless media can be improved through incorporation of vermicompost and its positive effect was clearly reflected in the yield of beet root.

The main mission shared by current Arrival Managers (AMAN's) is to assist the Air Traffic Controller (ATCo) in the tasks related to the traffic synchronisation in its arrival, relieving his workload. AMAN's goals are: sequencing, metering and merging with the only objective of optimising the time of arrival. On the other hand, AMAN's should be interconnected with other decision support tools which provide eficiency to ATM. It is expected that this versatility will convert them into a key collaborative tool within the air traffic synchronisation process.
