To assess students' perception about Kahoot! as an innovative learning tool in oral pathology- a qualitative study.

This qualitative study was conducted to investigate the perception of third-year dental students' about Kahoot! as an innovative learning, teaching, and assessment tool for the subject of Oral Pathology at the Fatima Jinnah Dental College, Karachi. This online App was implemented as a teaching and assessment tool in both the first and second semesters during the academic year 2019. Out of 75 students, 50 were females and 25 were males.

Simulation and Measurement of Aerosolisation in Different Chest Drainage Systems.

The aim of the study was to assess the degree of aerosolisation in different chest drainage systems according to different air leak volumes, in a simulated environment. This novel simulation model was designed to produce an air leak by passing air through and agitating a fluorescent fluid. The air leak volume and amount of fluorescent fluid were tested in various combinations and aerosolisation was assessed at 10-minute intervals using the ultraviolet light.

A Predictive Model for Height Tracking in an Adult Male Population in Bangladesh to Reduce Input Errors.

The advancement of ICT and affordability of medical sensors enable healthcare data to be obtained remotely. Remote healthcare data is erroneous in nature. Detection of errors for remote healthcare data has not been significantly studied.

Purity and mechanical strength of naturally frozen ice in wastewater basins.

A fairly clean ice cover can form over a contaminated water pond when the air-cooled surface of water freezes and impurities are efficiently expelled to the remaining water underneath. Natural freeze crystallization has recently been studied as a potential wastewater purification method with aqueous solutions on a laboratory scale. The effect of impurity inclusions on ice strength has been researched in model ice basins over the past few decades.

Endodontic Procedural Errors: Frequency, Type of Error, and the Most Frequently Treated Tooth.

Introduction. The aim of this study is to determine the most common endodontically treated tooth and the most common error produced during treatment and to note the association of particular errors with particular teeth. Material and Methods.

Photonic nanojet-enhanced nanometer-scale germanium photodiode.

A design challenge for photodiodes yielding both high speed and responsivity is the necessity to concentrate incident light into a subwavelength active volume region. Photonic nanojets have been reported in the literature as a means to focus an incident plane wave to a subwavelength-waist propagating beam with applications ranging from next-generation DVDs to characterizing subwavelength features within dielectric targets. In the present work, a new application of photonic nanojets is proposed, focusing electromagnetic energy into a photodiode.

Catalytic hydrogenation with frustrated Lewis pairs: selectivity achieved by size-exclusion design of Lewis acids.

Catalytic hydrogenation that utilizes frustrated Lewis pair (FLP) catalysts is a subject of growing interest because such catalysts offer a unique opportunity for the development of transition-metal-free hydrogenations. The aim of our recent efforts is to further increase the functional-group tolerance and chemoselectivity of FLP catalysts by means of size-exclusion catalyst design. Given that hydrogen molecule is the smallest molecule, our modified Lewis acids feature a highly shielded boron center that still allows the cleavage of the hydrogen but avoids undesirable FLP reactivity by simple physical constraint.

Hydrophobic ionic liquids with strongly coordinating anions.

Ionic liquids containing the hexafluoroacetylacetonate anion are immiscible with water and they exhibit strong metal-complexing ability.

Cobalt(II) complexes of nitrile-functionalized ionic liquids.

A series of nitrile-functionalized ionic liquids were found to exhibit temperature-dependent miscibility (thermomorphism) with the lower alcohols. Their coordinating abilities toward cobalt(II) ions were investigated through the dissolution process of cobalt(II) bis(trifluoromethylsulfonyl)imide and were found to depend on the donor abilities of the nitrile group. The crystal structures of the cobalt(II) solvates [Co(C(1)C(1CN)Pyr)(2)(Tf(2)N)(4)] and [Co(C(1)C(2CN)Pyr)(6)][Tf(2)N](8), which were isolated from ionic-liquid solutions, gave an insight into the coordination chemistry of functionalized ionic liquids.

Cefpodoxime proxetil compared with cefixime for treatment of typhoid fever in children.

In order to evaluate clinical and bacteriological efficacy of Cefpodoxime Proxetil (CP) in typhoid fever in comparison to cefixime (CF), we assessed 140 children with suspected typhoid fever. Fulfilling inclusion criteria finally 40 culture confirmed typhoid fever were allocated in randomized double blind clinical trial (RCT) to receive therapy with either oral CP (16 mg/kg/day, n = 21) or oral CF (20 mg/kg/day, n = 19) for 10 days. The two groups were comparable in their clinical and baseline characteristics.

Imidazolium ionic liquids as solvents for cerium(IV)-mediated oxidation reactions.

Use of imidazolium ionic liquids as solvents for organic transformations with tetravalent cerium salts as oxidizing agents was evaluated. Good solubility was found for ammonium hexanitratocerate(IV) (ceric ammonium nitrate, CAN) and cerium(IV) triflate in 1-alkyl-3-methylimidazolium triflate ionic liquids. Oxidation of benzyl alcohol to benzaldehyde in 1-ethyl-3-methylimidazolium triflate was studied by in-situ FTIR spectroscopy and 13C NMR spectroscopy on carbon-13-labeled benzyl alcohol.
