Alkaline hydrolysis of ethyl acetate is essentially an irreversible and second order reaction. Industrial importance of the reaction product, sodium acetate, necessitate for process improvement in terms of maximum conversion and economical usage of raw materials. Statistical design of experiments was utilized to enhance conversion in both batch and plug flow reactors.A full two level factor...

Verification of low-level C/C++ requires a precise memory model that supports type unions, pointer arithmetic, and casts. We present a new memory model that splits memory into a finite set of disjoint regions based on a pointer analysis. The main contribution is a field-, arrayand context-sensitive pointer analysis tailored to verification. We have implemented our memory model for the LLVM bitc...

Reliability of the listening test design has a great influence on the performance of the quality estimation model. In this paper we compare four different listening test designs by Monte Carlo simulation. Three common problems of interval scale ratings are included in the simulation, and their influences on the performance of estimating the underlying true quality are investigated. It turns out...

Organic farming represents strategic action for many European countries. Although the subsidies to organic farming sector are present there is no desired level of conversion from conventional to organic farming. System approach was applied in order to analyze the problem state. In order to provide proper strategy to achieve desired level of conversion the simulation model was build. By analysis...

This paper summarizes the current main methods of heterogeneous data conversion, focuses on the necessity of establishing the data conversion specification for China’s agricultural product quantity safety, as well as specifies the main designs and solutions for data conversion structure, data conversion process and data conversion format in research. Establishing a data conversion specification...

We introduce evolutionary resampling and combine (erc) – a genetic algorithm based selection scheme for training examples for a multilayer perceptron (MLP) classifier. The erc method is compared to various adaptive resample and combine techniques arc-fs, arc-lh and arc-x4. To diminish the dependencies on the size of the training data set (TDS) and the missing consideration of test set performan...

SOILS are usually considered to influence animal nutrition through the quantity and quality of the herbage they produce, so that the sequence is soil-plant-animal. The fact that soil is ingested by grazing animals indicates that a direct soil-animal effect also needs to be considered. Soil is taken in by animals along with herbage, as soil adhering to leaves, as soil on roots, and as earthworm ...

OBJECTIVES To evaluate the efficacy and safety of conversion from calcineurin inhibitors to sirolimus among liver transplant recipients with calcineurin inhibitor-induced complications. MATERIALS AND METHODS After receiving liver transplants, 25 patients with calcineurin inhibitor-induced complications (22 renal dysfunction and 3 new-onset diabetes mellitus) were converted from sirolimus to t...

hysteria is one of the conversion disorders that can be presented similar to neurological and organic disorders. conversion symptoms are usually associated with emotional conflicts of the patient. belching is often reported in patients with gastroesophageal reflux and is a rare manifestation of hysteria. the authors would describe a young female patient with serial belching that, after several ...
