Tematy:: battery capacity measurements
maintenance
telecommunications systems
Opis:: The article presents numerous problems with standby batteries used in telecommunications systems, with a particular emphasis placed on the assessment of their real capacity. The methods used to evaluate the technical condition of batteries and to measure their real capacity are presented. Also, the a new test device which measures the actual battery capacity is presented. The said measurement is based on the discharge test method and is performed with the use of a new TBA-A automated test unit. The article is targeted for electronic designers, managers and telecommunications hardware maintenance personnel, as well as for other telecommunications systems experts.

VRLA real capacity
Opis:: The article describes the results of testing a Benning AC/DC power supply, with integrated NIT TBA-ST meter. Such integration enables accurate and energy-efficient measurements of available capacity of individual 48-voltage VRLA/AGM batteries with remote management possibilities. The full compliance with the requirements for telecommunication power systems, the great functionality, upgrade ability, immunity to user errors and the high accuracy of capacity and voltage measurement of battery monoblocks of proposed solution are presented.

Opis:: Introduction. The problem concerning the impact of pregnancy on diabetic complications is a matter for discussion as there is some evidence suggesting that pregnancy may trigger development or progression of diabetic chronic complications. However, currently available data concerning this issue is still controversial. Objective. The aim of the study was to evaluate the impact of obstetric history on the development of chronic microangiopatic and macroangiopatic complications in type 1 diabetic women. Materials and Method. The retrospective study comprised 226 white Caucasian type 1 diabetic women, including 190 parous and 36 nulliparous women. Anthropometric data, information concerning the course of the disease, including metabolic control and chronic complications, together with obstetric history, were registered. Results. Parous women were older (p<0.001), but did not differ significantly regarding metabolic control in the course of the disease (p>0.05) and diabetes duration (p>0.05) from nulliparous subjects. There were no significant differences in the incidence (p>0.05) nor onset (p>0.05) of chronic diabetes complications between the groups. The number of deliveries did not correlate with either the incidence nor the onset of chronic complications. Longer DM duration at the moment of first delivery was related to the higher incidence of retinopathy (p<0.01), nephropathy (p<0.05) and neuropathy (p<0.001). Conclusions. The incidence of chronic diabetic complications does not differ between parous women and the subjects that were never pregnant, and is not related to the number of pregnancies.
