A systematic set of geo-referenced 154 soil samples were collected from the Karimnagar district, Telangana state, India, covering the entire rice growing area using GPS (Global positioning system) and the maps showing the spatial variability of individual macronutrients (N, P, K and S) were generated using Arc-info GIS (Geographic information system). The soil samples were analysed for physicochemical properties and available macronutrients. The available N status ranged from 119.17-784.0 kg ha-1 while the available P, K and S status varied from 12.61-88.46 kg ha-1, 105.68-754.4 kg ha-1 and 5.85-75.5 mg kg-1 respectively. Analytical results and the GPS data were used for the preparation of thematic map showing spatial distribution of N, P, K and S status, mandal-wise in the district. Locations of soil sampling sites of Karimnagar district were marked on the base map on 1:50,000 scale prepared from state revenue maps and digitized using Arc-info GIS. The delineation study clearly indicated that the available N was found to be low in 61.7% of soil samples of Karimnagar district, while phosphorus is in medium status. Nearly 33.8 and 62% of the surface soils were medium and high in available K, respectively. Most of rice growing soil samples were low (39%) in available sulphur in the district. The GIS-aided thematic maps indicated that 49.73, 11.85 and 24.4% of the total geographical area of Karimnagar district was deficient in the N, P and S, respectively. © 2017, Technoscience Publications.

Polycyclic Aromatic Hydrocarbons (PAHs) are a group of organic pollutants, containing carbon and hydrogen, composed of two or more condensed benzene rings in linear, angular, and cluster arrangements. Number of benzene rings may vary between 2 to 13. Sometimes sulphur, nitrogen and oxygen atoms may get readily substituted in the benzene ring1. These are non-polar, hydrophobic and readily soluble in hydrophobic solvents like fat, oil, ethereal solvents. The aqueous solubility of PAHs decreases with increasing molecular size. The hydrophobicity of PAHs plays key role in high persistence and low bioavailability to microbial attack and retained environment for longer times without degradation2. The PAHs namely phenanthrene, anthracene and pyrene are common PAHs pollutants that occur in all contaminated sites. © 2016, Global Research Online. All rights reserved.

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.

Correlation and path analysis studies were made for yield and its attributing traits in fifty blackgram genotypes. Based on correlation studies, it was observed that the number of branches per plant, number of clusters per plant, number of pods per plant, number of pods per cluster, pod length and number of seeds per pod showed highly significant positive correlation with seed yield per plant at genotypic level and improvement of these characters might contribute to high seed yields in blackgram. Path analysis revealed the highest positive direct effects on seed yield by number of seeds per plant followed by number of pods per plant, number of seeds per pod, pod length, number of branches per plant and 100 seed weight. Therefore these characters must be given priority in selecting for high yielding varieties in blackgram.

Interoperability Cross Atlantic Trials (ICATS), a two year Demonstration project, was launched in September 2013, under the framework of the Single European Sky (SES) initiative, and co-financed by the SESAR Joint Undertaking (SJU). ICATS primary objective is to quantify operational benefits enabled by the International Civil Aviation Organization (ICAO) inter-region exchange of flight object data including 4D Trajectories for trans- Atlantic flights. ICATS successfully demonstrated the feasibility of integrating two different regional implementations of the flight object by means of a Flight Information Exchange Model (FIXM) based Global Flight Object (GFO) concept and associated technical infrastructure. The infrastructure was deployed at Indra and Air Navigation Service Provider (ANSP) facilities in Europe and at the Florida NextGen Testbed (FTB) at Embry Riddle Aeronautical University in Daytona, Florida for conduct of the ICATS Live Flight Trial in spring 2014. The ICATS Live Flight Trial successfully demonstrated significant operational improvements both in terms of Fuel Efficiency and CO2 Emissions, as well as improved accuracy and predictability of key data derived from the flight object for Air Traffic Control (ATC) use. ICATS met or exceeded a number of the quantitative benefit targets established during the initial project definition and planning activity.

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 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.

This paper presents a benchmarking analysis of the efficiency and productivity of the air navigation service providers in Europe. Its aim is to determine the relative position of each air navigation service provider in terms of efficiency, the potential for achieving specific performance targets, and how close or far each organization is from the optimal efficiency level determined by the most efficient amongst their peers. The study is based on Data Envelopment Analysis (DEA), a nonparametric method extended in operations research and economics for the estimation of production frontiers, that is used to empirically measure productive efficiency of Decision Making Units (or DMUs).

Traffic Demand Forecast is a key aspect of Air Traffic Management (ATM), even more relevant recently as becomes increasingly more important to effectively scale capacity and associated resources (Air Traffic Controllers amongst them) to match the actual demand. In the case of ATM, many different demand forecasts can be considered, from the simplest to the most complicated ones, all aiming to provide a reliable forecast with the maximum time anticipation, thereby allowing the Network Managers at the different network levels to anticipate the needs to fulfill. However, there is no real indicator assessing the real accuracy of these forecasts. In this scenario it has been launched by CRIDA a long-term research activity with the goal to define reliability indicators that can be applied to traffic forecasts to fill in the described gap. This study will be performed through the availability of samples of both real-time flight plan information and post-flight data, and divided into several analysis phases. This reliability index is envisioned as a valuable complementary tool in combination with any traffic forecasts, as it is intended to provide the user improved awareness of the results obtained by using a particular demand forecast. Thus, this paper addresses an analysis of real ATM system data in order to determine both predictability and accuracy indicators which will eventually combine for a reliability index. The promising results of the first stage of this research activity are presented here, showing some already applicable conclusions.
