Histomorphology of the Hypothalamo – Neurosecretory System of the Indian Scad, Decapterus tabl (Berry)

Hypothalamo-neurosecretory complex of Decapterus fabl consists mainly of the nucleus preopticus (NPO), nucleus lateral is tuberis (NL T) and their zonal tracts. The neurosecretory cells of NPO are generally bipolar and stain readily with aldehyde fuchsin (AF) and chrom-alum -hematoxylin-phloxine (CAPH) but they are also positive to acid fuchsin in Mallory's triple stain. NPO is a paired structure situated on either side of the third ventricle antero-dorsal to the optic chiasma. It is highly vascularized structure and looks inverted L.-shape in the sagittal section

Functional outcome following open reduction and internal fixation of proximal humerus fractures with locking compression plate

Background: Proximal humerus fractures (PHFs) are common upper extremity fractures representing break in humerus bone. Incidences of PHFs increased in last few years due to life style changes and increased road accidents. Appropriate management strategy for PHFs is still uncertain. The aim of current study is to assess the functional outcome following open reduction and internal fixation of proximal humerus fractures using locking compression plates.Methods: Current study is a descriptive investigation conducted on 31 PHFs patients admitted to baby memorial hospital, calicut, between January 2013 to June 2014. Surgical management of PHFs was done by open reduction and internal fixation using locking compression plates and functional outcomes and complications of the employed treatment modality were investigated.Results: PHFs were observed to be common in 41-60 years age group, with 65% males being affected. Road accidents and domestic falls were observed to be the most common causes of PHFs in younger and elderly populations respectively. Three parts PHFs were observed to be more prevalent, followed by two and four parts fractures. Results of current study revealed that majority of PHFs united by 8-10 weeks duration with 22.58% cases with excellent and 41.93%, 16.12% and 19.35% cases with good, moderate and poor constant and Murley score respectively. Two patients reported post-operative complication of shoulder stiffness, while one patient each reported plate impingement, varus maluion, infection and varus malunion with intraarticular screw cut-out.  Conclusions: Locking compression plates (PHILOS/PHLP) is an efficient treatment modality for proximal humerus fractures allowing early mobilization and good functional outcome

Branchial, renal and hepatic lesions in an estuarine mullet, Liza parsia Hamilton - Buchanan, induced by sublethal exposure to BHC

Gill of Liza parsia exposed to sublethal concentration (0.5 ppm) of BHC responded initially with the copious secretion of mucus followed by oedematous separation of epithelial lining cells from the basement membrane. Fusion of secondary gill lamellae, tissue hyperplasia and multiple telangiectases (aneurysms) were noticed on day 10 of the exposure. By day 15, the entire interlamellar spaces became filled with the hyperplastic epithelium. Kidney revealed an initial hypertrophy of the cells lining proximal convoluted tubules followed by shrinkage in the glomerular tufts resulting in the increase of Bowman's space and oedema. Tubulonecrosis, hyperemia and fibrosis were noticed in the reneal tissue after day 19 of BHC intoxication. Exposure to BHC elicited an initial dilation of bile canaliculi, enhanced secretion of bile and cellular hypertophy on day 4. Necrotic changes like excessive vacuolation, and karyorrhexis and karyolysis were seen on day 8. By day 10 and 15, complete vacuolation of hepatocytes, pycnosis of nuclei and focal necrosis were noticed

Nonlinear dynamics of the interface of dielectric liquids in a strong electric field: Reduced equations of motion

The evolution of the interface between two ideal dielectric liquids in a strong vertical electric field is studied. It is found that a particular flow regime, for which the velocity potential and the electric field potential are linearly dependent functions, is possible if the ratio of the permittivities of liquids is inversely proportional to the ratio of their densities. The corresponding reduced equations for interface motion are derived. In the limit of small density ratio, these equations coincide with the well-known equations describing the Laplacian growth.Comment: 10 page

Impact of Destination Attributes on Tourists Destination Selection: With Special Reference to Cultural Triangle of Sri Lanka

Sri Lanka is one of the fastest-growing tourist destinations in the world. Amongst tourists’attractions, “Cultural Triangle”, a region of the cultural heritage of the country has becomethe highest income generating destination. However, when compared with the othertourists’ destinations of the country, the number of tourists visiting the cultural triangle islow. As the literature reveals, the attributes of the destination matter in destinationselection by the international tourists. Thus, considering the importance of this region asthe top income contributor but not in terms of the number of tourists' visits, this studyproblematizes the impacts of destination attributes on tourist`s destination selection.Accordingly, the objective of this study is to identify the destination attributes and theirrelationship with the tourists’ destination selection decisions. Data was collected throughquestionnaires from a sample of 222 foreign tourists who visited the cultural triangleduring 2019 through a selected travel agent. Results of the multiple regression analysisrevealed that attributes of Amenities, Destination Attractions, Accessibility, AncillaryServices, and Destination Environment as having a moderate positive relationship whilst,the service quality weak positive relationship with Tourist’s Destination selection.Destination attraction was identified as the most influential factor of all attributes. Thefindings of this study can be used by policymakers in developing destinations for tourists’attractions in the country

Can deficit irrigations be an optimum solution for increasing water productivity under arid conditions? A case study on wheat plants

Water scarcity is of growing concern in many countries around the world, especially within the arid and semi-arid zones. Accordingly, rationalizing irrigation water has become an obligation to achieve the sustainable developmental goals of these countries. This may take place via using deficit irrigation which is long thought to be an effective strategy to save and improve water productivity. The current study is a trial to evaluate the pros and cons of using 50 and 75 % of the irrigation requirements (IR) of wheat (deficit irrigations) versus 100 %IR, while precisely charting changes in wheat growth parameters, antioxidant enzymes in plant shoots and the overall nutritional status of plants (NPK contents). Accordingly, a field experiment was conducted for two successive seasons, followed a split-plot design in which deficit irrigations (two irrigations to achieve 50 % of the irrigations requirements (IR), three irrigations to attain 75 % IR, and four irrigations to fulfill 100 % IR) were placed in main plots while four different studied wheat cultivars were in subplots. Results obtained herein indicate that deficit irrigations led to significant reductions in growth parameters and productivity of all wheat cultivars, especially when using 50 % IR. It also decreased NPK contents within plant shoots while elevated their contents of proline, peroxidase, and catalase enzymes. On the other hand, this type of irrigation decreased virtual water content (VWC, the amount of water used in production on ton of wheat grains). Stress tolerance index (STI), and financial revenues per unit area were also assessed. The obtained values of grain productivity, STI, VWC and financial revenues were weighted via PCA analyses, and then introduced in a novel model to estimate the efficiency of deficit irrigations (ODEI) whose results specified that the overall efficiency decreased as follows: 50 %IR < 75 %IR < 100 %IR. In conclusion, deficit irrigation is not deemed appropriate for rationalizing irrigation water while growing wheat on arid soils

Reduced graphene oxide-multiwalled carbon nanotubes hybrid film with low Pt loading as counter electrode for improved photovoltaic performance of dye-sensitised solar cells

In this work, the role of reduced graphene oxide (rGO) with hyperbranched surfactant and its hybridisation with multiwalled carbon nanotubes (MWCNTs) and platinum (Pt) nanoparticles (NPs) as counter electrode (CE) were investigated to determine the photovoltaic performance of dye-sensitised solar cells (DSSCs). Sodium 1,4-is(neopentyloxy)-3-(neopentyloxycarbonyl)- 1,4-dioxobutane-2-sulphonate (TC14) surfactant was utilised as dispersing and stabilising agent in electrochemical exfoliation to synthesise graphene oxide (GO) as initial solution for rGO production prior to its further hybridisation and fabrication as thin film. A chemical reduction process utilising hydrazine hydrate was conducted to produce rGO due to the low temperature process and water-based GO solution. Subsequently, hybrid solution was prepared by mixing 1 wt% MWCNTs into the produced rGO solution. TC14-rGO and TC14-rGO_MWCNTs hybrid solution were transferred into fluorine-doped tin oxide substrate to fabricate thin film by spraying deposition method. Finally, the CE films were prepared by coating with thin Pt NPs. Photoanode film was prepared by a two-step process: hydrothermal growth method to synthesise titanium dioxide nanowires (TiO2 NWs) and subsequent squeegee method to apply TiO2 NPs. According to solar simulator measurement, the highest energy conversion efficiency (η) was achieved by using CE-based TC14-rGO_MWCNTs/Pt (1.553%), with the highest short current density of 4.424 mA/cm2. The highest η was due to the high conductivity of CE hybrid film and the morphology of fabricated TiO2 NWs/TiO2 NPs. Consequently, the dye adsorption was high, and the photovoltaic performance of DSSCs was increased. This result also showed that rGO and rGO_MWCNTs hybrid can be used as considerable potential candidate materials to replace Pt gradually
