Aim: Hoarseness of voice is generally due to change in quality of voice. The etiology of hoarseness of voice varies from benign conditions to malignant disease, hence should not be ignored. All cases of hoarseness of voice persisting for more than 3 weeks should be investigated for the underlying disease. It may indicate either malignancy of larynx or silent bronchogenic carcinoma. A retrospect...

Isothermal oxidation tests of mechanically treated Ti-Beta-21S (TIMET, Ti–15Mo–3Nb–3Al–2Si, ASTM Grade 21) were performed under dry air at 650, 700 and 750 °C for 100 h compared to untreated samples. Two different mechanical surface treatments used: ultrasonic shot-peening (SP) laser-shock peening (LSP). The study investigates the effect both on kinetics process role atmospheric nitrogen insert...

Dey et al. [1] derived an equation of state (EOS) for matter in strange stars (SS from hereon) with quark masses showing chiral symmetry restoration (CSM) and an interquark potential which (i) has asymptotic freedom built into it, (ii) shows confinement at zero density (ρB = 0) and deconfinement at high ρB. This EOS gives a stable configuration for chargeless, β-stable quark matter. The SS deri...

OBJECTIVES The aim of this study was to emphasize the necessity of a standard in segmentation threshold and algorithm for measuring volume and surface area of mastoid air cell system (MACS). METHODS First, we obtained axial computed tomography scans of 54 normal temporal bones from 27 subjects. Then, we manipulated Hounsfield units (HU) image data in DICOM (digital imaging and communications ...

O(2) photoreduction by photosynthetic electron transfer, the Mehler reaction, was observed in all groups of oxygenic photosynthetic organisms, but the electron transport chain mediating this reaction remains unidentified. We provide the first evidence for the involvement of A-type flavoproteins that reduce O(2) directly to water in vitro. Synechocystis sp. strain PCC 6803 mutants defective in f...

Tomat memiliki nilai ekonomi yang cukup baik sehingga menartik petani untuk membudidayakannya. Selain itu mengandung vitamin C tinggi berfungsi mencegah berbagai penyakit seperti sehatan gigi dan gusi, mempercepat sembuhnya luka serta kerusakan atau pendarahan pada pembuluh darah. Namun permasalahan dihadapi oleh tomat di Wolasi adalah gangguan yaitu hawar daun tomat. Transfer teknologi tepat g...
