In the recent past, tracking applications increasingly develop towards distributed sensor scenarios. In many cases, such schemes must cope with low observable targets in cluttered environments. Furthermore, such a setup suffers from communication delays and timely delayed sensor data. However, Track-before-Detect methodologies are not suitable for processing time delayed data yet. In this paper...

Advancements in information and communication technologies have enhanced our possibilities to communicate worldwide, eliminating borders and making it possible to interact with people coming from other cultures like never happened before. Such powerful tools have brought us to reconsider our concept of privacy and social involvement in order to make them fit into this wider environment. It is p...

The cellobiose lipid of Cryptococcus humicola, 16-(tetra-O-acetyl-β-cellobiosyloxy)-2-hydroxyhexadecanoic acid, is a natural fungicide. Sensitivity of the cells of Saccharomyces cerevisiae to the fungicide depends on a carbon source. Cellobiose lipid concentrations inducing the leakage of potassium ions and ATP were similar for the cells grown in the medium with glucose and ethanol. However, th...

Growth at near-zero specific growth rates is a largely unexplored area of yeast physiology. To investigate the physiology of Saccharomyces cerevisiae under these conditions, the effluent removal pipe of anaerobic, glucose-limited chemostat culture (dilution rate, 0.025 h(-1)) was fitted with a 0.22-microm-pore-size polypropylene filter unit. This setup enabled prolonged cultivation with complet...

The present study assessed the use of hydrolysate of lipid extracted algal biomass (LEA) combined with the sugar factory wastewater (SFW) as a low cost nutrient and a carbon source, respectively for microalgal cultivation. Microalgal strain Ettlia sp. was both mixotrophically and heterotrophically cultivated using various amounts of hydrolysate and SFW. The culture which was grown in medium con...

Filamentous species of Ulva are ideal for cultivation because they are robust with high growth rates and maintained across a broad range of environments. Temperate species of filamentous Ulva are commercially cultivated on nets which can be artificially 'seeded' under controlled conditions allowing for a high level of control over seeding density and consequently biomass production. This study ...

While bitter manioc has been one of the most important staple crops in the central Amazon for thousands of years, there have been few studies of its cultivation in the fertile whitewater landscapes of this region. Anthropological research on bitter manioc cultivation in the Amazon has focused almost exclusively on long-fallow shifting cultivation in marginal upland areas of low soil fertility. ...

Marigold cultivation is now a profitable enterprise to the farmers, but the socioeconomic data and information of this flower are very scarce in Bangladesh. Therefore, the study was conducted to identify agronomic practices, analyze relative profitability, and input-output relationship during February 2011. Primary data were collected from 100 randomly selected farmers from Jessore and Jhenaida...

An efficient Agrobacterium-mediated durum wheat transformation system has been developed for the production of 121 independent transgenic lines. This improved system used Agrobacterium strain AGL1 containing the superbinary pGreen/pSoup vector system and durum wheat cv Stewart as the recipient plant. Acetosyringone at 400 microM was added to both the inoculation and cultivation medium, and picl...

Batch and fed-batch cultivation of Bacillus thurillgiellsis var. kurstaki was carried out to achieve high cell and spore density with maximum insecticidal activity. Cell cultivation was done in fully equipped fermentors under controlled conditions at different feed rates. Increased cell mass, high spore counts and improved insecticidal activity were achieved with fed-batch cultivation system. W...
