3 questions to Klaus Bahmann (Springer), Peter Gemmel (Thieme) and Angelika Lex (Elsevier) by Bruno Bauer
No full textIn the past years electronic books were booming at scientific libraries. E-books have established especially at medical libraries as an important part of the document supply in particular for students. The current interview with Klaus Bahmann (Springer), Peter Gemmel (Thieme) and Angelika Lex (Elsevier) informs about development, situation and outlook of e-books of three big scientific publishers. They spoke about the focal points in the supply and the diverse business models and the different estimation for the future development of electronic books.In den letzten Jahren haben elektronische Bücher an wissenschaftlichen Bibliotheken einen großen Aufschwung erfahren.

Echinococcosis/hydatidosis: socio-economic consequences and economic analyses of control programmes
No full textSocio-economic consequences of echinococcosis/hydatidosis in man and livestock are analysed. Cost-effectiveness and cost-benefit analyses of control programmes of the disease are discussed in order to provide the best control strategie
RFC3450: Asynchronous Layered Coding (ALC) Protocol Instantiation
No full textThis document describes the Asynchronous Layered Coding (ALC)
protocol, a massively scalable reliable content delivery protocol.
Asynchronous Layered Coding combines the Layered Coding Transport
(LCT) building block, a multiple rate congestion control building
block and the Forward Error Correction (FEC) building block to
provide congestion controlled reliable asynchronous delivery of
content to an unlimited number of concurrent receivers from a single
sender

No full textOver diagnosis of chronic obstructive pulmonary disease in an underserved patient population
No full textChristian Ghattas,1 Allen Dai,2 David J Gemmel,3 Magdi H Awad2 1Department of Internal Medicine, St Elizabeth Health Center, Youngstown, OH, USA; 2Northeast Ohio Medical University College of Pharmacy, Rootstown, OH, USA; 3Department of Medical Education and Research, St Elizabeth Health Center, Youngstown, OH, USA Introduction: While cross-national studies have documented rates of chronic obstructive pulmonary disease (COPD) misdiagnosis among patients in primary care, US studies are scarce. Studies investigating diagnosis among uninsured patients are lacking. Objective: The purpose of this study is to identify patients who are over diagnosed and thus, mistreated, for COPD in a federally qualified health center. Methods: A descriptive study was conducted for a retrospective cohort from February 2011 to June 2012. Spirometry was performed by trained personnel following American Thoracic Society recommendations. Patients were referred for spirometry to confirm previous COPD diagnosis or to assess uncontrolled COPD symptoms. Airway obstruction was defined as a forced expiratory volume in the first second of expiration (FEV1) to forced vital capacity ratio less than 0.7. Reversibility was defined as a postbronchodilator increase in FEV1 greater than 200 mL and greater than 12%. Results: Eighty patients treated for a previous diagnosis of COPD (n = 72) or on anticholinergic inhalers (n = 8) with no COPD diagnosis were evaluated. The average age was 52.9 years; 71% were uninsured. Only 17.5% (14/80) of patients reported previous spirometry. Spirometry revealed that 42.5% had no obstruction, 22.5% had reversible obstruction, and 35% had nonreversible obstruction. Conclusion: Symptoms and smoking history are insufficient to diagnose COPD. Prevalence of COPD over diagnosis among uninsured patient populations may be higher than previously reported. Confirming previous COPD diagnosis with spirometry is essential to avoid unnecessary and potentially harmful treatment. Keywords: chronic obstructive pulmonary disease, COPD, misdiagnosis, over diagnosis, spirometry, uninsured, underserve
Cleaner Air for Scotland Strategy – An Independent Review
No full textFirst paragraph: The air that we breathe is fundamental to human life and the quality of our environment. The quality of life lived is placed at short and longer term risk by pollution. In Scotland today, whilst industrial, domestic, agricultural, natural and transboundary pollution are all parts of the mix, pollution from transport is the single biggest source of concern. Tackling all sources requires concerted and systemic action

No full textRFC3452: Forward Error Correction (FEC) Building Block
No full textThis document generally describes how to use Forward Error Correction
(FEC) codes to efficiently provide and/or augment reliability for
data transport. The primary focus of this document is the
application of FEC codes to one-to-many reliable data transport using
IP multicast. This document describes what information is needed to
identify a specific FEC code, what information needs to be
communicated out-of-band to use the FEC code, and what information is
needed in data packets to identify the encoding symbols they carry.
The procedures for specifying FEC codes and registering them with the
Internet Assigned Numbers Authority (IANA) are also described. This
document should be read in conjunction with and uses the terminology
of the companion document titled, "The Use of Forward Error
Correction (FEC) in Reliable Multicast"
RFC3453: The Use of Forward Error Correction (FEC) in Reliable Multicast
No full textThis memo describes the use of Forward Error Correction (FEC) codes
to efficiently provide and/or augment reliability for one-to-many
reliable data transport using IP multicast. One of the key
properties of FEC codes in this context is the ability to use the
same packets containing FEC data to simultaneously repair different
packet loss patterns at multiple receivers. Different classes of FEC
codes and some of their basic properties are described and
terminology relevant to implementing FEC in a reliable multicast
protocol is introduced. Examples are provided of possible abstract
formats for packets carrying FEC
