Patients will be observed for abnormalities of the lid , conjunctiva, cornea and tear film by diffuse illumination aided by Schirmer's Test, corneal and conjunctival staining and conjunctival swab when required. Other factors like consciousness, use of a ventilator, preexisting comorbidities shall also be noted. Patients will be observed on Day1, 5, 6, and so on. 60 eyes of 30 patients were examined . In mechanically ventilated patients , 36 eyes (60%) had conjunctival hyperemia which resolved upon intervention which included antibiotics and lubricants . 18 eyes (9%) had conjunctival discharge which resolved upon intervention. 12 eyes (20%) were stain positive. The critically ill often develop ocular surface disorders, especially when sedated and immobilized. A close relationship was observed between these conditions and the inability to close one's eyes. The presence of ocular surface disease was closely correlated with the degree of lagophthalmos, which in turn was closely related to the depth of sedation or paralysis.","PeriodicalId":14491,"journal":{"name":"Invertis Journal of Science & Technology","volume":"18 1","pages":"93-97"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91061627","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the present investigation 0.01N Ammonium Molybdate doped ZTS crystal was grownusing single diffusion gel growthtechnique which has an advantage over normally employed solution growth method, in terms of controlled nucleation and hence better perfection. A significant morphological alteration was observed due to doping. The functional groups of pure and doped ZTS crystals were recorded and identified using Fourier Transform Infrared Spectroscopic (FTIR) analysis. A study on hardness variation due to doping was conducted using Vickers' Hardness Tests. The increase in hardness observed can be assigned to the impurity hardening effect as found to increased due to effect of dopant. The results obtained are elaborated and discussed in the paper.","PeriodicalId":14491,"journal":{"name":"Invertis Journal of Science & Technology","volume":"66 1","pages":"104-110"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81530773","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Portions of these blend films are exposed to swift heavy O 7+ ion radiations. Changes taking place in thermal, electrical and relaxation properties at various LiCF 3 SO 3 salt concentrations of all the blend specimens prior and after irradiation are thoroughly investigated. Relaxation time τ and Kohlrausch-William-Watt's exponent β which throw light on the relaxation dynamics of the blend samples are calculated using modulus formalism. For both, prior as well as after irradiation, all these properties are found to be optimum at 9 wt% of salt concentration. However, irradiation has led to a significant enhancement in these properties of the blends at all salt concentrations. Scaling of modulus is carried out to analyse time-composition superposition principle. Relaxation dynamics is observed to be independent of salt concentration in cases of both, pristine and irradiated blends.","PeriodicalId":14491,"journal":{"name":"Invertis Journal of Science & Technology","volume":"74 1","pages":"77-85"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73279808","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thermal properties of the samples are studied by means of Differential Scanning Calorimetry (DSC) revealed that the glass transition temperature increases for the composites [PVA + 10% SCN (Tg = 109°C)] compared to pure PVA (Tg = 97°C) samples. The dielectric characterization has been studied by means of impedance gain-phase analyzer.
