SUSY transformation of the Green function and a trace formula

An integral relation is established between the Green functions corresponding to two Hamiltonians which are supersymmetric (SUSY) partners and in general may possess both discrete and continuous spectra. It is shown that when the continuous spectrum is present the trace of the difference of the Green functions for SUSY partners is a finite quantity which may or may not be equal to zero despite the divergence of the traces of each Green function. Our findings are illustrated by using the free particle example considered both on the whole real line and on a half line

Training fisherwomen in fish processing

A project on training fisherwomen for their participation in rural development, sponsored by Ford Foundation (U.S.A), has been started by the Centre for Agricultural and Rural Development Studies, T.N AU.,at the Fisheries College, Tuticorin. The project alms to select a few literate rural women with leadership qualities for Imparting to them a training In the organisational and managerial aspects of a viable fish processing enterprise. It also alms to assist the trained fisherwomen in organising and operating cottage industries by continued technical backing and thus making the production units demonstration centres for the benefit of other women In the region. The preliminary survey helped in identifying 5 candidates from each of the 3 selected villages. The pre-survey revealed the respondents' choice of subject-areas to undergo training and their enthusiasm to learn techniques for the preparation of fish products like fish pickle and MasI Meen. It also revealed their desire to be exposed to new products like fish wafers, fish oil, fish meal, shark fin-rays etc. The pre- and post evaluations of the training programme helped In I) identifying training needs In the fields of marketing and financial management; II) Identifying some low-cost technological substitutes for some of the commercial products (eg: 'Gadi' for vineger); ill) identifying the products or techniques appreciated by the trainees and the products or techniques that received lukewarm response with reasons for such a response: Iv) Identifying the level of managerial efficiency gained by the trainees and the kind of support required for each Individual to start cottage industries. The programme Is being followed up by Interpersonal contacts and the co-ordinate efforts of the development departments

Annual reproductive cycle of the Rock Oyster Saccostrea cucullata (von Born)

The annual reproductive cycle of the rock oyster, Saccostrea cuculata (von Born) inhabiting Someshwar coast near Mangalore was investigated. The reproductive cycle commences with gametogenic activity during January - February, followed by gonadal development and maturation during March - May. Spawning is continuous from June to December, with two peaks, the first during late June to early September and the second during November to December

Larval development of the Rock Oyster Saccostrea cucullata (von Born)

The development of artificially fertilised eggs of the rock oyster, Saccostrea cucullata (von Born) was studied in the laboratory. The morphological and behavioural characteristics of the developing larvae were observed. A mixed diet of single celled algae consisting of Isochrysis galbana and Tetraselmis gracilis was fed to the larvae. The larval developmental stages observed include trochophore, D-veliger, late veliger, umbone stage, pediveJiger and plantigrade

An Effective Sentence Ordering Approach For Multi-Document Summarization Using Text Entailment

With the rapid development of modern technology electronically available textual information has increased to a considerable amount. Summarization of textual inform ation manually from unstructured text sources creates overhead to the user, therefore a systematic approach is required. Summarization is an approach that focuses on providing the user with a condensed version of the origina l text but in real time applicat ions extended document summarization is required for summarizing the text from multiple documents. The main focus of multi - document summarization is sentence ordering and ranking that arranges the collected sentences from multiple document in order to gene rate a well - organized summary. The improper order of extracted sentences significantly degrades readability and understandability of the summary. The existing system does multi document summarization by combining several preference measures such as chronology, probabilistic, precedence, succession, topical closeness experts to calculate the preference value between sentences. These approach to sent ence ordering and ranking does not address context based similarity measure between sentences which is very ess ential for effective summarization. The proposed system addresses this issues through textual entailment expert system. This approach builds an entailment model which incorpo rates the cause and effect between sentences in the documents using the symmetric measure such as cosine similarity and non - symmetric measures such as unigram match, bigram match, longest common sub - sequence, skip gram match, stemming. The proposed system is efficient in providing user with a contextual summary which significantly impro ves the readability and understandability of the final coherent summa

The potential link between corporate innovations and corporate competitiveness:Evidence from IT firms in the UK

Purpose: The purpose of this paper is to provide a thorough empirical investigation of the potential link between corporate innovations and corporate competitiveness in the context of the UK IT industry. Design/methodology/approach: This research uses a panel of 216 UK IT firms for the period from 2000 to 2016. The sample data for this study were extracted from the Worldscope, extracted from the Datastream database from Thomson Reuters. For the analysis of the data, the generalised method of moments model is applied. Findings: The results of this study provide empirical evidence that there exists a strong, positive link between corporate innovations and corporate competitiveness. Such evidence further reinforces the common view in the current literature of strategic management that because of the nature of their business, firms in the IT industry need to enhance their innovative capacities on a continual basis because of their critical role on these firms’ success and survival. Also, it is found that when the proxies for corporate innovations are lagged by two periods, their impact on corporate competitiveness becomes relatively more significant. However, when they are further lagged, i.e. by three periods, such an impact turns out to be relatively less pronounced. Research limitations/implications: The data gathered for this paper was restricted to IT-oriented firms in the UK. Using a secondary database (Datastream), the paper considered the period of 2000-2016. Originality/value: The research makes a significant contribution to the current debate on the relationship between information technology, innovation and performance, referred to in the literature as the productivity paradox, by studying the problem in the IT industry. It supports organisations from the sector in their efforts to deal with the dynamic nature of technological innovations and of the context where they operate. Methodologically, the way the study has measured the concepts of innovation and performance and the lessons learned from their analysis has also brought value to the research

Alternative Methods to Teach History of Anesthesia

Background: History of Anesthesia [HOA] may be taught through lectures, small group discussions, or by one-on-one teaching. HOA competes for scarce time in a busy didactic schedule and for coverage in mainstream medical journals devoted to anesthesiology. These efforts are hampered by the fact that HOA does not have any direct impact on the delivery of modern anesthesia, and the fact that these topics do not appear in written or oral board examinations. We describe three additional modalities to teach HOA to anesthesia residents that have been successfully employed by the Department of Anesthesiology at the University of Massachusetts: 1) Tours; 2) Historical Narratives and Novels; and 3) Movies and Video Clips. Conclusions: It is difficult to impart information using lectures due to time constraints and a very busy didactic schedule in residency programs. HOA related material does not get adequate coverage in standard textbooks of anesthesiology. We describe successful use of three modalities of imparting interesting information in an informal setting. Such efforts provide a unique experience during residency training. From preliminary reports we are confident that details from such tours, novels and movies remain imprinted in their memory for many years, perhaps permanently. These individuals are likely to remain advocates of history, and may choose to devote a part of their academic career towards exploration of HOA

Medical History for Anesthesiologists: Continuation of a Primer

Editor’s note: The absence of a recognized formal curriculum in anesthesia history means that many of us have known and unknown gaps in our knowledge. These gaps limit our ability to understand how things came to be, how things may become and how we can affect the future. I have asked Dr. Manisha Desai and Dr. Sukumar Desai to provide a primer on the history of medicine and anesthesia history. The goals of this primer are to educate and to help individuals target future study. Below is the second article in a continuing series
