A review of imperative technologies for wastewater treatment I: oxidation technologies at ambient conditions

A review of imperative technologies for wastewater treatment II: hybrid methods

The [2 + 2] photocycloaddition is undisputedly the most important and most frequently used photochemical reaction. In this review, it is attempted to cover all recent aspects of [2 + 2] photocycloaddition chemistry with an emphasis on synthetically relevant, regio-, and stereoselective reactions. The review aims to comprehensively discuss relevant work, which was done in the field in the last 20 years (i.e., from 1995 to 2015). Organization of the data follows a subdivision according to mechanism and substrate classes. Cu(I) and PET (photoinduced electron transfer) catalysis are treated separately in sections 2 and 4, whereas the vast majority of photocycloaddition reactions which occur by direct excitation or sensitization are divided within section 3 into individual subsections according to the photochemically excited olefin.

CLINICAL NEUROSURGERY Edited by Barnes Wordall. Vol. 18. (Pp. 557; illustrated; £8 25.) Churchill Livingstone: Edinburgh. 1971. CLINICAL NEUROSURGERY Edited by G. T. Tindall. Vol. 19. (Pp. 598; illustrated; £12.) Churchill Livingstone: Edinburgh. 1972. The Congress of Neurosurgeons began in 1951 on the initiative of a group of younger neurosurgeons. In the last 20 years its membership has grown from 69 to over 1,000, but it has retained its original intentions and virility by a constitution which ensured that the office bearers and organizers were always young men. Residents in training are encouraged to join, financial concessions make it possible for them to attend meetings, and these are organized as an educational exercise, by inviting established authorities to give lectures on selected topics, chosen to provide a balanced programme. As a result Clinical Neurosurgery is a valuable volume which all neurosurgeons look forward to each year; it is in quite a different class from the usual conference tome, full of brief and unconnected papers of widely varying quality. As the title suggests Clinical Neurosurgery includes excellent clinical reviews but the two recent volumes include also a section of seminars on fundamental research-in volume 18 on coma and sleep, in volume 19 on basic mechanisms of memory. It is also the custom to invite a senior neurosurgical citizen as guest of honour and his two or three papers afford an opportunity for historical and philosophical reflections as well as an experienced perspective on clinical and experimental work. Add to this the refreshing presidential address, from one of the (angry?) young men of neurosurgery and it will be clear that these volumes really do include something of interest for every neurosurgeon, whatever his own interests or prejudices. It is a relief to be able so warmly to recommend these books, when the question posed by so many other books is whether anyone would really want to read them. The most recent volume has a more consistent theme than former ones, and that is 'head injury'. It includes papers on mechanisms as revealed by animal experiment and by a pathologist who visited the scene of the accident before examining the brains of head injury fatalities. There are chapters on engineering and socio-psychological aspects of accident prevention, as well as down to earth clinical accounts of metabolic disorders, testing for acoustic vestibular 36 damage, and aspects of prognosis. This is a significant contribution to the literature on head injury.

An approach for reduction of false predictions in reverse engineering of gene regulatory networks

A vote is considered as one of the most important legal rights a citizen can practice in a democratic country. Presently, votes are cast in two manners: manual mode, i.e., paper voting and the semi-manual mode using e-voting machine (EVM). Both systems require the accumulation of the voters in centralized voting booths. Several discrepancies arise due to the lack of security management in a centralized voting system. These can be avoided if a decentralized voting system can be implemented thereby providing a high-security impact. Blockchain is a technology that acts as a backbone for the highly secured parallel economy like the Bitcoin system. If this technology can be implemented as a security measure in a decentralized e-voting system, this will ensure the total security and authenticity of the voting system. In this paper, an endeavor has been made to design a blockchain-based e-voting system. Initial experimentation displayed satisfactory prospects of the system.

Automatic Speaker Verification (ASV) is a challenging task over the mobile/IP based system as the coding introduces some loss in system performance This paper reports on the work in progress to examine the impact of GSM-AMR codec used in mobile at its various bit rates and G729 codec for VoIP, along with different kind of noise and packet loss scenario for the speech signal PURE YOHO database has been used for the evaluation of this task Respective encoder and decoders are used back to back on wideband clean microphone speech to simulate the real-life situation Evaluation of performance is done through the measurement of Equal Error Rate (EER) It has been shown that the loss due to GSM-AMR codec is very significant for speaker verification compared to undecoded speech Though the packet loss and bit rate may degrade the quality of speech but it is not significant to detection of speaker's identity

Coronary artery disease (CAD) is one of the leading causes of mortality and morbidity globally. Nowadays, it is spreading at an alarming rate. Recently, there is an increasing interest to develop simple and non-invasive automated methods for reliable diagnosis of CAD. Studies reported that the use of single-channel phonocardiogram (PCG) signal for detecting weak CAD murmurs caused by the stenosed coronary arteries due to turbulent blood flow. In this work, we introduce a new framework with multi-channel data acquisition system to classify CAD and normal subjects. The proposed method does not require any reference signal such as an electrocardiogram (ECG) signal for PCG signal segmentation as reported in the earlier studies. Subsequently, the study has used five different features, such as spectral moments, spectral entropy, moments of PSD function, autoregressive (AR) parameters, and instantaneous frequency derived from frequency representations of PCG signals. These features have captured the specific details related to the disease. We use an artificial neural network (ANN) for the classification task. Experimental results show that the AR features well-performed. We achieve an accuracy of 74.24% by using multi-channel recorded data where as the best performance obtained using single-channel signal is 69.69%.
