Influence of Smoking Consumption and Nicotine Dependence Degree in Cardiac Autonomic Modulation

Abstract Background: Smoking consumption alters cardiac autonomic function. Objective: Assess the influence of the intensity of smoking and the nicotine dependence degree in cardiac autonomic modulation evaluated through index of heart rate variability (HRV). Methods: 83 smokers, of both genders, between 50 and 70 years of age and with normal lung function were divided according to the intensity of smoking consumption (moderate and severe) and the nicotine dependency degree (mild, moderate and severe). The indexes of HRV were analyzed in rest condition, in linear methods in the time domain (TD), the frequency domain (FD) and through the Poincaré plot. For the comparison of smoking consumption, unpaired t test or Mann-Whitney was employed. For the analysis between the nicotine dependency degrees, we used the One-way ANOVA test, followed by Tukey's post test or Kruskal-Wallis followed by Dunn's test. The significance level was p < 0,05. Results: Differences were only found when compared to the different intensities of smoking consumption in the indexes in the FD. LFun (62.89 ± 15.24 vs 75.45 ± 10.28), which corresponds to low frequency spectrum component in normalized units; HFun (37.11 ± 15.24 vs 24.55 ± 10.28), which corresponds to high frequency spectrum component in normalized units and in the LF/HF ratio (2.21 ± 1.47 vs 4.07 ± 2.94). However, in the evaluation of nicotine dependency, significant differences were not observed (p > 0.05). Conclusion: Only the intensity of smoking consumption had an influence over the cardiac autonomic modulation of the assessed tobacco smokers. Tobacco smokers with severe intensity of smoking consumption presented a lower autonomic modulation than those with moderate intensity.

Assessment of the VoIP Transmission Quality over Digital Power Line Carrier Channels

This article is devoted to the research of VoIP transmission quality over Digital Power Line Carrier channels. Assessment of quality transmission is performed using E-model. Paper considers the possibility of joint using of Digital Power Line carrier equipment with different architecture in one network. As a result of the research, the rule for constructing of multi-segment Digital Power Line Carrier channels was formulated. This rule allows minimizing the transmission delay and saving frequency resources of high voltage Power Line Carrier range.

The Research of Increase of Channel Efficiency for IP Traffic Transmission over Digital Power Line Carrier Channels

This article is devoted to the research of channel efficiency for IP-traffic transmission over Digital Power Line Carrier channels. The application of serial WAN connections and header compression as methods to increase channel efficiency is considered. According to the results of the research an effective solution for network traffic transmission in DPLC networks was proposed.

Distribució de revistes científiques en format digital

L'aparició de les revistes en format digital posa de nou de manifest la necessitat de disposar de bons mecanismes de distribució i accés a les mateixes. Això encara esdevé més rellevant en els actuals moments de concentració en grans grups empresarials de l'edició i la distribució de les revistes de l'anomenat àmbit científic, tècnic i mèdic (STM: “scientific, technical and medical”). Davant d'aquest fenomen, encara ho tenen més complicat les publicacions amb una circulació més restringida per raons de llengua o d'especialització. És el cas de moltes revistes publicades a Catalunya, editades i distribuïdes per canals diferents als del sistema STM comercial internacional. Davant d’aquesta problemàtica, el Consorci de Biblioteques Universitàries de Catalunya (CBUC) ha encarregat el present informe. Un dels objectius fonamentals del CBUC és facilitar l'accés dels usuaris a la informació especialitzada; dins d'aquesta es vol prestar un suport especial als continguts creats a Catalunya per tal de facilitar-ne la seva utilització i contribuir al seu desenvolupament futur. Dins l’actual moment de canvi provocat per la irrupció de l’edició digital, es corre el risc de que els continguts catalans no tinguin la suficient presència i utilització en aquest nou suport, cosa que suposaria un evident endarreriment. Per tal d’evitar-ho, el CBUC vol explorar les implicacions i les possibilitats de crear plataformes o portals per a la difusió de les revistes erudites catalanes, en el cas que no ho puguin fer pels canals comercials internacionals. A nivell operatiu aquest informe intenta respondre a les següents preguntes: Què és un portal de revistes científiques?, Quins elements s’han de preveure en la seva constitució?, Quines alternatives de servei hi ha?, Quines problemàtiques tècniques es plantegen? i Existeixen iniciatives o inquietuds semblants a les plantejades pel CBUC?
