    Description: Over the last two decades, improvements in developing computational tools have made significant contributions to the classification of images of biological specimens to their corresponding species. These days, identification of biological species is much easier for taxonomists and even non-taxonomists due to the development of automated computer techniques and systems. In this study, we developed a fully automated identification model for monogenean images based on the shape characters of the haptoral organs of eight species: Sinodiplectanotrema malayanum, Diplectanum jaculator, Trianchoratus pahangensis, Trianchoratus lonianchoratus, Trianchoratus malayensis, Metahaliotrema ypsilocleithru, Metahaliotrema mizellei and Metahaliotrema similis. Linear Discriminant Analysis (LDA) method was used to reduce the dimension of extracted feature vectors which were then used in the classification with K-Nearest Neighbor (KNN) and Artificial Neural Network (ANN) classifiers for the identification of monogenean specimens of eight species. The need for the discovery of new characters for identification of species has been acknowledged for log by systematic parasitology. Using the overall form of anchors and bars for extraction of features led to acceptable results in automated classification of monogeneans. To date, this is the first fully automated identification model for monogeneans with an accuracy of 86.25% using KNN and 93.1% using ANN.

    Notes: Abstract Alluvial (Inceptisols and Entisols) soils containing illite as dominant clay mineral released significantly higher amounts of K to 0.3 M NaTPB than smectitic Black (Vertisols) and kaolinitic Red (Alfisols) soils. Exchange rate indices derived from the plots of K released to 0.3 M NaTPB versus log t were also higher for illitic soils than for kaolinitic and smectitic soils. Magnitudes of both surface and internal K released from different soils were in the sequence: illitic 〉 smectitic 〉 kaolinitic. Data of K release to 0.3 M NaTPB could be described by first order rate equation. In parabolic plots, existence of a linear relationship throughout the period of exchange with NaTPB indicated the absence of film diffusion controlled processes. Diffusion coefficients calculated from radial diffusion equation were dependent upon texture and clay mineralogy of soils and decreased sharply with time for kaolinitic and smectitic soils. Illitic soils, however, maintained higher values of diffusion coefficients over extended periods of time.

    Notes: Abstract An extract of the hydrophyteMyriophyllum spicatum L. was found to be toxic to first- and fourth-instar larvae of the mosquitoes,Culex quinquefasciatus Say,Culex tarsalis Coquillett,Culiseta incidens (Thomson),Aedes aegypti L., and chironomid midges in the laboratory. When first-stage larvae were exposed to the extract, the lowest concentration (6.4 mg extract/100 ml H2O) produced 86,60, and 48% mortality inC. incidens, C. quinquefasciatus, andA. aegypti, respectively. Higher concentrations caused 100% mortality in both first and fourth instars (63.75 mg/100 ml H2O or more). In general, the biocidal activity of the extract was found to be similar when first- and fourth-stage larvae were exposed. Some mortality in the successive pupal and adult stages was observed when fourth-stage larvae were exposed to the extract, but mortality occurred only in the various larval instars when first instars were exposed. Among the chironomids,Tanytarsus spp. was more tolerant to the extract thanChironomus spp. In addition to the biocidal activity against immature mosquitoes, the extract was found to show a unique activity acting as an attractant to both sexes of adultC. quinquefasciatus andA. aegypti. The response elicited inA. aegypti appeared to be somewhat higher than that inC. quinquefasciatus. In general, the percentage of males responding to water treated with the extract was higher than that of the females. The extract at higher concentrations seemed to show some repellency at the outset to both species, but induced positive responses later on.

    Notes: Abstract Extracts of two species of green algae, filamentousRhizoclonium hieroglyphicum Kütz and a phytoplankton,Chlorella ellipsoidea Gerneck, obtained with solvents in the laboratory were assayed againstAedes aegypti L.,Culex quinquefasciatus Say, andCuliseta incidens (Thomson). On extraction with petroleum ether, groundR. hieroglyphicum yielded an active crude extract which was chromatographed on a neutral alumina column and eluted consecutively with petroleum ether, benzene, and methanol. All three eluted fractions were found to induce significant mortality in test mosquito species. The benzene-eluted fraction was the least toxic. The methanol-eluted fraction was the most toxic to all species and exhibited juvenile hormone-like activity; it also caused morphogenetic changes in emerging adults. All three fractions delayed the rate of development of mosquito larvae by 2–5 days. Three supernatants ofC. ellipsoidea obtained on different occasions were tested against first instars ofC. quinquefasciatus. After the confirmation of their activity, all supernatants were extracted with diethyl ether, combined, and assayed against first- and fourth-stage larvae of the three mosquito species. The first-stage larvae ofC. quinquefasciatus andC. incidens were approximately three times more suspectible than those ofA. aegypti. However, fourth-stage larvae of the former two species were about twice as susceptible to the extract as those of the latter species. Dead first-stage larvae of all the species had a shrunken appearance. In general,C. ellipsoidea extract was quicker acting than that ofR. hieroglyphicum.

    Notes: Summary The labile pool of zinc in alkaline soils was determined by the application of isotopic dilution principle under laboratory and greenhouse conditions using corn and wheat as experimental crops. Simultaneously, the selective distribution of65Zn isotope between the solid and solution phases in 0.1M CaCl2 was determined. The labile pool-selective distribution coefficient diagrams were used for delineating the soils into different categories of Zn availability. The variations of the parameters of zinc availability were related to the physical and chemical properties of the soils. The results indicated that the plants and the DTPA extractant removed forms of zinc that may not undergo isotopic exchange in indifferent electrolytes. The values of labile pool obtained by the laboratory and greenhouse methods were highly correlated. The selective distribution coefficient was related to the organic matter and clay contents of the soils (R=0.78). A comparison of the values of labile pool of zinc measured with corn and wheat crops indicated that the two crops differ appreciably in affecting the isotopic dilution of65Zn in their root zone. The results indicate that the greenhouse method of determining the labile pool of zinc may be used as a reference procedure for calibrating soil test methods that extract amounts of Zn equal or proportional to that removed by growing plants in alkaline soils. The DTPA procedure of determining the available Zn in such soils meets the requirements of a satisfactory soil test method. re]19760726

    Notes: Abstract The effect of blending of commercially available full fat and defatted rice brans in India from modern multistage rice mills with parboiling/stabilizing facilities in different food products in comparison to those obtained from laboratory milling of rice is reported. Bread volume and cookie spread decreased but muffin volume increased with the addition of different types of bran to wheat flour, however, the cookie spread factor was not affected by addition of full fat rice bran. The yields of the extrudate were increased by the blending of full fat rice bran but were decreased by the addition of defatted rice bran. Rice brans could be added to different food products to the extent of 5–10%. However, the full fat rice bran could not be used for production of extruded snack food.
