Seasonal observation on physico-chemical parameters were correlated with population of ostracoda in southern region off Rameswaram, Gulf of Mannar, Ramanathapuram district, Tamil Nadu, southeast coast of India, by collecting bottom sediment and water samples in the inner shelf region. 11 samples were collected every season, for four different seasons, namely, northeast monsoon (October 2010), winter (January 2011), summer (April 2011) and southwest monsoon (July 2011) seasons. Spatial and seasonal variation in physico-chemical and hydrographic parameters and sampling stations having higher population of ostracoda were critically analysed with the observed parameters. Highest population of ostracoda was recorded during summer followed by southwest monsoon, northeast monsoon and winter season. Cluster analysis reveal that station 9 falls in all seasons under favourable location, during different seasons and is having the most congenial environment for ostracoda to thrive. Depth, pH, dissolved oxygen, salinity, EC, TDS, nitrite and silica show positive correlation, and turbidity, nitrate and phosphate show negative correlation with total population of ostracoda.
Field experiment was conducted at Agricultural Research Station, Kovilpatti during rabi season (October 2017 to January 2018) to find out the suitable plant geometry, levels of fertilizers and foliar spray of micronutrients (Zn and Fe) at 15, 30 and 45 DAS to improve the growth and yield of sorghum variety K12 (dual purpose). The experiment was laid out in randomized block design with three replication and twelve treatments. The treatment consists of two plant geometry, three different dose of fertilizer and foliar spray of micronutrients viz., 0.5% ZnSO4 + 0.2% FeSO4 at 15, 30 and 45 DAS. Observation on growth parameters, grain yield, stover yield, fodder qualities and Rainfall use efficiency were recorded. The experimental results shows that reduced plant spacing of 30 × 15 cm together with enhanced application of 50:25:25 kg NPK ha -1 + foliar spray of 0.5% ZnSO4 + 0.2% FeSO4 at 15, 30 and 45 DAS significantly increased the growth parameters viz., plant height, stem girth days to flowering and drymatter production. This attributes ultimately resulted in higher grain (3961 kg ha -1 ) and stover (13972 kg ha -1 ) yield of dual purpose sorghum compared to recommended practice of rainfed sorghum having 45 × 15 cm spacing and application of recommended 40:20:0 kg NPK ha -1 alone.
Vocabulary Bombardment is an evidence based therapy procedure, in which the client is made to listen to amplified target words only through auditory modality. A standardized set of words are provided in a repeated and intensified manner for a period of time. Individuals with Broca’s aphasia have naming difficulties with limited vocabulary, therefore the aim of this study focuses on effect of intense vocabulary bombardment on word retrieval through auditory mode for a client with aphasia. A case study was done on an individual with Broca’s aphasia. Method includes a material, which had tasks to recollect words. The test had 12 sub-tests under it, with each sub-test pertaining to a specific category. The client was provided with intervention with this material for a period of 4 weeks and the word retrieval ability was checked. Significant improvement was obtained following the intervention with vocabulary bombardment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
