Regulatory effects of polyamines on membrane-bound acetylcholinesterase
1974
The effects of putrescene, spermidine and spermine on membrane-bound acetylcholinesterase from human erythrocyte ‘ghosts’ and the solubilized enzyme of the electric organ of the electric eel were studied by kinetic methods. Measurements were made by using a photometric method which made it possible to record the enzyme reaction in the steady-state phase. Substrate-concentration-dependent activation and inhibition of acetylcholinesterase by polyamines is similar to that by Na+, K+, Ca2+, Mg2+ and certain quaternary and bisquaternary amines. The kinetics suggest an allosteric reaction mechanism. On the basis of the kinetic results a role for the polyamines as modulators of synaptic acetylchol…
Electrical distribution substation remote diagnosis and control system
2014
This paper presents the conception, design, set up and realization of a prototype system for telemanagement of a MV/LV substation. The prototype has been developed according to the current standards. This system allows to monitor the status of the MV/LV substation box, of the medium voltage equipment, of the transformer and of the low voltage equipment. In particular, the system acts when some specified events occur. The prototype has been realized by using a DAQ; the software that implement the telemanagement system has been developed in LabVIEW environment. The system allows a remote monitoring of the quantities of interest that is carried out using the TeamViewer software able to establi…
The influence of treatment programmes on the recidivism of juvenile and adult offenders: An european meta-analytic review
1999
Abstract Meta-analyses have examined the effectiveness of different treatment techniques on delin-quent and criminal behaviour in America and Europe. In one of the last meta-analyses, that integrated the results of programmes applied in European countries (Redondo, Garrido, and Sanchez-Meca, 1997), the global effect size obtained for all treatment and effectiveness measures (Psychological factors, education, etc.) was d = 0.3039 (r = 0.15). In general, it muld be interpreted that treatment groups surpassed controls by 15%, On this work, the results of a meta-analysis to determine which treatments are more effective in reducing on recidivism rates are presented. A total of 32 European studie…
A cardiovascular educational intervention for primary care professionals in Spain: positive impact in a quasi-experimental study
2015
Background Routine general practice data collection can help identify patients at risk of cardiovascular disease. Aim To determine whether a training programme for primary care professionals improves the recording of cardiovascular disease risk factors in electronic health records. Design and setting A quasi-experimental study without random assignment of professionals. This was an educational intervention study, consisting of an online-classroom 1-year training programme, and carried out in the Valencian community in Spain. Method The prevalence rates of recording of cardiovascular factors (recorded every 6 months over a 4-year period) were compared between intervention and control group. …
Ensuring Effective Prevention of Iodine Deficiency Disorders
2016
To access publisher's full text version of this article click on the hyperlink at the bottom of the page Programs initiated to prevent iodine deficiency disorders (IDD) may not remain effective due to changes in government policies, commercial factors, and human behavior that may affect the efficacy of IDD prevention programs in unpredictable directions. Monitoring and outcome studies are needed to optimize the effectiveness of IDD prevention. Although the need for monitoring is compelling, the current reality in Europe is less than optimal. Regular and systematic monitoring surveys have only been established in a few countries, and comparability across the studies is hampered by the lack o…
Pesticides and Herbicides: Residue Determination
2016
Pesticide and herbicide residue determination in food is becoming an especially imperative and challenging issue. Commonly, it involves the simultaneous trace analysis of hundreds of compounds belonging to many chemical classes. This article provides a review of the current status of the routine methods in the monitoring and control of these residues and discusses the analytic problems arising at each stage of the procedure. The role of mass spectrometry in screening, identification, and confirmation of target and nontarget pesticides is highlighted. Consideration is given to new developments and future trends.
On the robust design of unknown inputs Takagi-Sugeno observer
2012
This paper deals with the observer design for Takagi-Sugeno (T-S) fuzzy models subject to unknown inputs and disturbance affecting both states and outputs of the system. Sufficient conditions to design an unknown input T-S observer are given in Linear Matrix Inequalities (LMIs) terms. Relaxations are introduced by using intermediate variables. Numerical example is given to illustrate the effectiveness of the given result.
