On sounding the bladder some roughness of a foreign bod/was felt. Patient placed under the influence of chloroform, morphia injected under skiu and median operation perfomed. On introducing finger into bladder, the grass stick was felt, it was bent, hooked by finger and brought out. One end of it was covered by deposit of salt. There was also a nuall soft stone which crumbled during extraction ...

Aspergillus terreus gave the overall best results in alpechin at approximately 80% concentration, degrading organic material by 53%, expressed as COD, and 67%, expressed as BOD. Degradation of the total phenol content, which included the great majority of phenolic compounds, reached 69%.

The Metal-Ferroelectric-Semiconductor FET (MFSFET) device is structurally similar to a regular MOSFET device except that the gate material is composed of a ferroelectric material (PZT) normally sandwiched between two layers of silicon dioxide. Ferro models the PZT material with a set of four material parameters; the saturation polarization Ps, the remanent polarization Pr, the coercive field Ec...

This work proposes a novel geometry field effect transistor with graphene as a channel-graphene field-effect transistor (GFET), having a hybrid contact that consists of an ohmic source/drain and its extended part towards the gate, which is capacitively coupled to the channel. The ohmic contacts are used for direct current (DC) biasing, whereas their capacitive extension reduces access region le...

Classical French vertical flow constructed wetlands (VFCWs) plant comprises two stages of treatment which the first one nearly respects standard outlet levels. It is therefore attractive to use recirculation on a single vertical stage to reduce its footprint when outlet levels required are not too severe regards to nitrification. The present study aims at evaluating performances and limits of a...

Few-layer black phosphorus (BP) attracts much attention owing to its high mobility and thickness-tunable band gap; however, compared with the commonly studied transition metal dichalcogenides (TMDCs), BP has the unfavorable property of degrading in ambient conditions. Here, we propose an inverted dual gates structure of ultrathin BP FET to research the air adsorption on BP. In fabrication proce...

Amongst the technologies available, the upflow anaerobic sludge blanket (UASB) process has been one of the most widely applied methods for municipal wastewater treatment especially in countries of warm climatic conditions like India. However, past about one decade has witnessed rapid decline in the UASB popularity and its implementation. There has been criticism from various sections on the per...

Conduction band modification due to shear stress is investigated. Mobility in singleand double-gate SOI FETs is modeled for Silicon thin body orientation (001) and (110) under general stress conditions. Decrease of conductivity mass induced by uniaxial [110] tensile stress leads to mobility enhancement in the stress direction in ultra-thin body SOI MOSFETs.

Accurate FET Model parameters need to be determined to give accurate simulation results for RF amplifiers. The accuracy required varies depending on the application of the final amplifier. For Doherty amplifiers, a high accuracy is required for the transfer characteristic of the amplifier. An amplifier was simulated using a model obtained from data sheet information, and then built. Measurement...
