Abstract: In the present study Jatropha curcus leaves were extracted with acetone and it was tested against the filarial vector Culex quinquefaciatus. The toxicity (LC50 and LC90 ) values were also worked out against different larval and pupal forms. The larval and pupal durations were extended and delayed in emergence of adult was also noted and it may be due to various compounds present in it (Jatrophine, Cyclic heptapeptide, Cyclogossine A and Saponins). These compounds show toxic effect on larval, pupal and growth inhibitory factors. Hence Jatropha curcus can be used for the control of filarial vector Culex quinquefaciatus at sewage water ecosystem.

Abstract: The microbiological quality of raw, boiled and oven roasted oysters were determined. The study was based on isolation and density enumeration of microbe indicator organisms and other pathogens. Thirty oyster ' s samples were analyzed from each of the raw, boiled and roasted samples. Salmonella typhi, Shigella dysenteriae, Escherichia coli, Erwinia amylovora and Aerobacter aerogenes were detected in the raw oysters with mean bacterial count of 1.73x106 cfu/g. The boiled and roasted oysters contained only Bacillus cereus and Bacillus subtilis respectively. However, traces of non-pathogenic Staphylococcus sp and Micrococcus luteus were also found in the boiled and roasted samples. The mean bacterial count in boiled and in the roasted oysters were <100 cfu/g. The fungi Mucor mucedo and Rhizopus nigricans were also isolated from roasted oyster meat due to poor handling. The mean fungal count in the roasted oyster meat was <10. The isolation of faecal coliforms and other pathogenic microorganisms was considered a high medicinal risk especially in places where oysters are eaten raw.

Abstract: Studies were carried out between June 2006 and May 2007 to evaluate the concentration of six heavy metals (iron, zinc, copper, lead, manganese and chromium) by atomic absorption spectrophotometer in the gills and muscles of six commercial fresh water fish species Mormyrus rume rume (Vallenciennes, 1847), Mormyrus tapirus (Pappenheim, 1905), Marcusenius cyprinoides (Linnaeus, 1758), Labeo coubie (Ruppell, 1832), Hepsetus odoe (Bloch,1794) and Protopterus annectens annectens (Owen, 1839) from Anambra River South East Nigeria. The gills on the average absorbed more metals in all the fishes studied when compared with the muscles except in Hepsetus odoe (Bloch, 1794). The order of heavy metal concentration in the fish species was Fe>Zn>Cu>Mn>Cr>Pb. While the concentration of Fe (except in the gills of M.rume rume (Vallenciennes,1847), Zn and Pb in the muscles and gills of all the six fish species studied were within the WHO and FEPA prescribed limits for food fish, that of Cu, Mn and Cr were above the prescribed limits thus indicating contamination of these fish species by these metals. The toxicological implications of this finding in relation to aquatic ecosystem and human health are discussed.

Abstract: A study of Tinea capitis and Tinea corporis infections among school children was carried out on pupils in 2 private and 2 public primary schools, within Obio-Akpor Local Government Area (LGA) of Rivers State, Nigeria. Of the 1320 pupils studied (632 males, 688 females), aged 5-13 years, 79 cases were clinically diagnosed for infection with 73 cases infected with tinea capitis and 6 cases with Tinea corporis. A total prevalence rate of 5.99% was observed, with 5.5% being Tinea capitis infection. Majority of the pupils (91%) had dry-inflammatory lesions while 9% had wet-inflammatory lesions. Males were more infected with Tinea capitis than females (64.6% vs 35.4%; p<0.05). Children within 8-10 years of age were more infected (45.6%) compared to ages 5 to 7 years (27.8%) and 11 to 13 years (26.6%). Pupils from the public schools were significantly more infected than pupils from private schools (93.6% vs 6.33%). Trichophyton, Microsporum and Epidermophyton sp. were isolated with a 50% recovery rate.

Abstract: Using multi-temporal European Remote-sensing Satellites (ERS-1/-2) and Canadian Radar Satellite (RADARSAT-1) synthetic aperture radar (SAR) data over the Louisiana coastal zone, we characterize seasonal variations of radar backscattering according to vegetation type. Our main findings are as follows. First, ERS-1/-2 and RADARSAT-1 require careful radiometric calibration to perform multi-temporal backscattering analysis for wetland mapping. We use SAR backscattering signals from cities for the relative calibration. Second, using seasonally averaged backscattering coefficients from ERS-1/-2 and RADARSAT-1, we can differentiate most forests (bottomland and swamp forests) and marshes (freshwater, intermediate, brackish and saline marshes) in coastal wetlands. The student t-test results support the usefulness of season-averaged backscatter data for classification. Third, combining SAR backscattering coefficients and an optical sensor -based normalized difference vegetation index can provide further insight into vegetation type and enhance the separation between forests and marshes. Our study demonstrates that SAR can provide necessary information to characterize coastal wetlands and monitor their changes.

Abstract: The application of global algorithms to optical satellite imagery often fails to correctly assess the concentrations of seawater constituents (chlorophyll, CHL, suspended sediments, SS and yellow substance , YS) in spectrally complex marine environments. Additional problems may come from inaccurate radiometric, atmosperic and geometric corrections of the remotely sensed imagery. This issue is currently analyzed using a data set of seawater samples and MODIS images taken in the Tuscany Sea (Central Italy). The analysis demonstrates that the mentioned problems mainly introduce amplitude variations in the measured reflectance. This may have negative effects on the outcome of inversion algorithms based on the minimization of conventional spectral errors. Such effects can be notably reduced by using an error index derived from the angle between measured and simulated reflectance vectors, which is insensitive to spectral amplitude variations. The potential of a classical and the new error indicates is first evaluated by regressing their values against concentration differences of optically active constituents found over the available sample pairs. The performance of the two error indices are then assessed within an inversion algorithms applied to the same samples. The results obtained show the potential of the new error index particularly to improve the estimation of CHL concentration.

Keywords: Information fusion, decision tree classifiers
Abstract: We describe a system that uses decision tree-based tools for seamless acquisition of knowledge for classification of remotely sensed imagery. We concentrate on three important problems in this process: information fusion, model understandability and handling of missing data. Importance of multi-sensor information fusion and the use of decision tree classifiers for such problems have been well-studied in the literature. However, these studies have been limited to the cases where all data sources have a full coverage for the scene under consideration. Our contribution in this paper is to show how decision tree classifiers can be learned with alternative (surrogate) decision nodes and result in models that are capable of dealing with missing data during both training and classification to handle cases where one or more measurements do not exist for some locations. We present detailed performance evaluation regarding the effectiveness of these classifiers for information fusion and feature selection, and study three different methods for handling missing data in comparative experiments. The results show that surrogate decisions incorporated into decision tree classifiers provide powerful models for fusing information from different data layers while being robust to missing data.

Abstract: Completely cloud-free remotely sensed images are preferred, but they are not always available. Although the average cloud coverage for the entire planet is about 40 percent, the removal of clouds and cloud shadows is rarely studied. To address this problem, a closest spectral fit method is developed to replace cloud and cloud -shadow pixels with their most similar non-clouded pixel values. The objective of this paper is to illustrate the methodology of the closest spectral fit and test its performance for removing clouds and cloud shadow in images. The closest spectral fit procedures are summarized into six steps, in which two main conceptions , location-based one-to-one correspondence and spectral-based closest fit, are defined. The location-based one-to-one correspondence is applied to identify pixels with the same locations in both base image and auxiliary images. The spectral-based closest fit is applied to determine the most similar pixels in an image. Finally, this closest spectral fit approach is applied to remove cloud and cloud-shadow pixels and diagnostically checked using Landsat TM iamges. Additional examples using Quick-Bird and MODIS images also indicate the efficiency of the closest spectral fit for removing cloud pixels.

Abstract: Pixel-swapping algorithm is a simple and efficient technique for sub-pixel mapping (Atkinson, 2001 and 2005). It was initially applied in shorelilne and rural land-cover mapping but has been expanded to other land-cover mapping. However, due to its random initializing process, this algorithm must swap a large number of sub-pixels and therefore it is computation intensive. This computing power consumption intensifies when the scale factor is large. A new, modified pixel-swapping algorithm (MPS) is presented in this paper to reduce the computation time, as well as to improve sub-pixel mapping accuracy. The MPS algorithm replaces the original random initializing process based on a sub-pixel/pixel spatial attraction model. The new algorithm was used to allocate multiple land-covers at the sub-pixel level. The results showed that the MPS algorithm outperformed the original algorithm both in sub-pixel mapping accuracy and computational time. The improvement is especially significant in the case of large scale factors. Furthermore, the MPS is less sensitive to the size of neighboring sub-pixels and can still result in increased accuracy even if the size of neighbors is small. The MPS was also much less time consuming, as it reduced both the iterations and total amount of swapping needed.

Abstract: This study examines and validates a technique for spatial enhancement of thermal satellite images for urban heat island analysis, using a nightime ASTER satellite image. The technique, termed Emissivity Modulation, enhances the spatial resolution while simultaneously correcting the image derived temperatures for emissivity differences of earth surface materials. A classified image derived from a higher resolution visible wavelength sensor is combined with a lower resolution thermal image in the emissivity correction equation in a procedure derived from the Stephan Bolzmann law. This has the effect of simultaneously correcting the image-derived "Brightness Temperature" (Tb) to the true Kinetic Temperature (Ts), while enhancing the spatial resolution of the thermal data. Although the method has been used for studies of the urban heat island, it has not been validated by comparison with " in situ" derived surface or air temperatures and researchers may be discouraged from its use due to the fact that it creates sharp boundaries in the image. The emissivity modulated image with 10 m pixel size was found to be highly correlated with 18 in situ surface and air temperature measurements and a low Mean Absolute Difference of 1K was observed between image and in situ surface temperatures. Lower accuracies were obtained for the Ts and Tb images at 90 m resolution. The study demonstrates that the emissivity modulation method can increase accuracy in the computation of kinetic temperature, improve the relationship between image values and air temperature and enable the observation of microscale temperature patterns.

Keywords: Asynchronism, camera, three-dimensional photogrammetric analysis
Abstract: The three -dimensional photogrammetric analysis of image sequences is a growing field of application. For the analysis of dynamic processes one important precondition has to be guaranteed: All cameras have to be synchronized, otherwise the results are affected by asynchronism. In this article a new method is presented, which can determine the asynchronism of an arbitrary number of image sequences.In contrast to already existing methods, in the new approach the asynchronism is modeled in object space and then converted into an interpolation function containing a set of unknowns for each camera. In this form the asynchronism is introduced into an extended bundle adjustment, in which the unknows are solved simultaneously with the image orientation parameters and the object coordianates of the points. Therefore, the approach has no restrictions with regard to the number and the set-up of the cameras in the acquisition network. Furthermore, both the temporal and spatial analysis step are carried out simultaneously. We have implemented the suggested method and have run a number of experiments in the context of vehicle impact testing. First, sequences with a frame rate of 1,000Hz observing an object with a speed of up to 7 m/s and an asynchronism of 0.8 ms were analyzed. The accuracy of the object point determination could be improved by a factor of 10. Then, five sequences of a vehicle impact test with a speed of 15.6 m/s were investigated. Here, errors in the object coordinates of up to 30 mm could be eliminated using the new approach. Given the small tolerances in car development, this improvement in point accuracy is significant.

Abstract: Functional efficiency of caprine macrophages and B cells and the effect of dexamethasone on their function were studied in the present investigation. Macrophages induced more proliferation in unprimed animals whereas B cells stimulated significantly (p<0.01) increased proliferation of T cells in sensitized animals, indicating the specific and memory response, characteristics of adaptive immune system. S.aureus induced more proliferation followed by M.paratuberculosis and tetanus toxoid. Autologous macrophages and B cells were used as target cells to assess the cytotoxicity by MTT colorimetric method. M.paratuberculosis primed macrophages and B cells were subjected to cytotoxicity more than S.aureus and TT primed macrophages and B cells. Dexamethasone did not influence on the antigen presentation and cytotoxicity function of caprine macrophages and B cells. Caprines may be considered as corticosteroid resistant species.

Abstract: A phytoremediation study was carried out at Pariyej reservoir, an internationally important wetland listed in Asian Directory of Wetlands, designated as a "Wetland of International Importance" and a proposed community reserve of Gujarat State, India, to ascertain the degree of heavy metal contamination. The study focused on assessment of heavy metal accumulation in certain aquatic macrophytes used as biomonitors, in comparison with water and sediments (abiotic monitors) for phytoremediation. Roots, stems and leaves of native aquatic plants (biomonitors) represented by seven species:Ipomea aquatica, Forsk, Eichhornia crassipes, (Mart.) Solms, Typha angustata Bory & Chaub, Echinochloa colonum (L.) Link, Hydrilla verticillata (L.f.) Royle, Nelumbo nucifera Gaerth and Vallisneria spiralis L.along with surface sediments and water, were analyzed for Cd, Co, Cu, Ni , Pb and Zn contamination. The greater accumulation of heavy metals was observed in Nelumbo nucifera and the poor content in Echinochloa colonum. Based on the concentration and toxicity status observed in the lake ' s vegetation, the six heavy metals are arranged in the following descending order: Zn>Cu>Pb>Ni>Co>Cd. Compared with the standard, normal and critical toxicity range in plants. The detected values of Cd and Pb falls within normal range, while that of Co and Ni was within the critical range. However ,Zn and Cu showed the highest accumulation with alarming toxicity levels, which are considered as one of the most hazardous pollutants in Pariyej reservoir.Species like Typha angustata and Ipomoea aquatica are also proposed as bioremediants, which are the two most useful plant species in phytoremediation studies due to their ability to accumulate heavy metals in high concentration in the roots. The results showed the significant differences in accumulaion of metals like Zn, Cu and Pb in different plant organs, in roots than that of stems and leaves. High positive correlation between combinations of different metal pairs in plant ' s root, stem or leaf system was established. The potential use of these wetland plants in phytoremediation is also discussed.
