    Description: The Bay of Bengal (BoB) is strongly density stratified due to large freshwater input from various rivers and heavy precipitation. This strong vertical stratification, along with physical processes, regulates the transport and vertical exchange of surface and subsurface water, concentrating nutrients and intensifying the oxygen minimum zone (OMZ). Here, we use basinwide measurements to describe the spatial distributions of nutrients, oxygen, and phytoplankton within the BoB during the 2013 northeast monsoon (November–December). By the time riverine water reaches the interior bay, it is depleted in the nutrients nitrate and phosphate, but not silicate. Layering of freshwater in the northern BoB depresses isopycnals, leading to a deepening of the nutricline and oxycline. Oxygen concentrations in the OMZ are lowest in the north (〈5 µM). Weak along-isopycnal nutrient gradients reflect along-isopycnal stirring between ventilated surface water and deep nutrient-replenished water. Picoplankton dominate the phytoplankton population in the north, presumably outcompeting larger phytoplankton species due to their low nutrient requirements. Micro- and nanoplankton numbers are enhanced in regions with deeper mixed layers and weaker stratification, where nutrient replenishment from subsurface waters is more feasible. These are also the regions where marine mammals were sighted. Physical processes and the temperature-salinity structure in the BoB directly influence the OMZ and the depth of the oxycline and nutricline, thereby affecting the phytoplankton and marine mammal communities.

    Notes: We report thick superconducting films of Y-Ba-Cu-O on oxidized silicon substrates. The critical temperatures for onset and zero resistance are 96 and 77 K, respectively. X-ray diffraction analysis predicts 1, 2, 3 composition and orthorhombic phase of the film.

    Notes: The origin, length, cross-sectional area, the fascicular number, their area and arrangement, total myelinated fibre count, and diameter-spectra of the optic nerve were investigated in the Indian buffalo. The majority of the optic nerve fibres are myelinated fibres arranged in fascicles. The peripheral portion of the nerve has a significantly greater number of myelinated nerve fibres. The right and left optic nerves do not differ significantly in their length, cross-sectional area and the number of myelinated fibres. The number, area and arrangement of the nerve fascicles varies (the peripheral portion contains a greater percentage of small-sized ones). The total interfascicular area is significantly greater than the fascicular area. The external diameter of the myelinated fibres ranges from 1 to 12 microns. Histograms reveal an unimodal distribution of these fibres with a peak at 2 microns. Thinner fibres predominate in the peripheral portion.〈section xml:id="abs1-2"〉〈title type="main"〉Zusammenfassung Anatomische Untersuchung des N. opticus des indischen Biiffels (Bubalis bubalis)Ursprung, Länge, Querschnittszone, Bündelanzahl nach Lage und Anordnung, Gesamtzahl der myelinhaltigen Fasern und Durchmesserspektrum des N. opticus wurden beim indischen Büffel untersucht. Die Mehrzahl der Nervenfasern sind myelinhaltige, faczikulär angeordnete Fasern. Der periphere Abschnitt des Nerven besitzt eine bedeutend grofiere Anzahl myelinhaltiger Nervenfasern. Rechter und linker Nerv unterscheiden sich in ihrer Länge, Querschnittszone und Anzahl der myelinhaltigen Fasern nicht bemerkenswert. Zahl, Lage und Anordnung der Nervenbündel variieren (der periphere Abschnitt enthält einen größeren Prozentsatz dünner Bündel). Das gesamte interfaszikuläre Gebiet ist bedeutend größer als das faszikulare. Der außendurch-messer der myelinhaltigen Fasern reicht von 1 bis 12 Mikra. Histogramme enthüllen eine gleichmäßige Verteilung dieser Fasern mit einem Gipfel bei 2 Mikra. Im peripheren Abschnitt herrschen dünnere Fasern vor.〈section xml:id="abs1-3"〉〈title type="main"〉RésuméRecherches anatomiques sur le nerf optique (N. opticus) chez le Buffle indien (Bubalis bubalis)Les recherches ont porté sur ľ origine, la longueur, la surface de section, le nombre de fascicules, leur étendue et leur disposition, la numération totale des fibres myélinisées et leur spectre de diamètres dans le nerf optique de Buffle indien. La majorite des fibres de ce nerf sont myélinisées et groupees en faisceaux. La partie peripherique du nerf possede de façon significative un nombre plus élevé de fibres myélinisées. Le nerf droit et le nerf gauche ne different pas de façon significative en ce qui concerne leur longueur, leur surface de section et le nombre de fibres myélinisées. Le nombre, le calibre et la disposition des faisceaux nerveux sont variables (la partie peripherique contient un pourcentage plus élevé de fibres minces). La surface totale des parties interfasciculaires est de façon significative plus grande que la surface fasciculaire. Le diametre exterieur de fibres myélinisées s étend de 1 à 12 microns. Les histogrammes révèlent une disposition unimodale de ces fibres avec un pic a 2 microns. Les fibres les plus minces predominent a la partie périphérique.〈section xml:id="abs1-4"〉〈title type="main"〉ResumenInvestigaciones anatomicas en el nervio optico del búfalo índico (Bubalis bubalis)Se investigaron en el nervio óptico del bufalo indico el origen, la longitud, las zonas de cortes transversales, el número de fasciculos segun su situación y distribución, el número y los diferentes diametros de las fibras mielinicas. La mayoria de las fibras nerviosas son mileínicas, distribuidas en fasciculos, que se encuentran especialmente en la regién periférica del nervio. No hay diferencias notables entre el lado derecho e izquierdo con respecto a su longitud, las zonas de cortes transversales y el número de fibras mileínicas. Número, situación y distribución de los fasciculos nerviosos son variables (conteniendo la porción periférica un porcentaje mayor de fasciculos delga-dos). El territorio interfascicular en su totalidad es mucho mas grande que el fascicular. El diametre externo de las fibras mielinicas varia entre 1 y 12 micra. Histogramas revelan una distribucion equitativa de estas fibras con prevalencia de las de 2 micra. En la periferia predominan fibras mas delgadas.

    Notes: The anatomy of the spinal cord segments was studied and recorded for the impala. The root attachment lengths were greatest at C3, T10 and L3 cord segment levels in the respective regions. As to the root emergence length the greatest lengths were observed at C7, T]0〉 L5 and S1 cord segment levels respectively. The interroot interval was longest at C2, T8 and L1 segments respectively. The longest cord segments were C2, T13, L2 and S2 segments. The widest cord segments of their respective regions were C7, T1, L5 and S1 cord segments. As to segment volume C3, T13, L2 and S1 were the most voluminous cord segments in the respective cord regions.Statistical analysis revealed a high correlation among all of the study parameters suggesting a high degree of multicolinearity.Gross anatomical relationships concerning the location of the spinal cord segments with respect to the vertebrae were studied. The cord segments C], Ts–T4 and Li–L3 were within their vertebral limits. In the impala the spinal cord terminated at the midlevel of S4 vertebra.
