半导体延时电路

通信与信息技术 1973年第1期 21-28页

作者： James J.pinto

半导体延时电路通常采用最普通的定时机构,即通进一个定时电阻R对定时电容c充电,使电压从起始数值V上升到一个标志时间间隔结果的电压V, 如图1。定时电容上的电压呈指数上升,只有采用恒流充电才能保持直线上升。

Sugarcane mosaic caused by Sugarcane Mosaic Virus (ScMV) is one of the most important virus diseases of sugarcane. In the present study, changes in the transcription profile obtained by cDNA-AFLP analysis were investigated in two sugarcane varieties contrasting to ScMV resistance, when challenged with a severe virus strain. Healthy plants derived from meristem tip tissue culture were mechanically inoculated under greenhouse controlled conditions and sampled at 24, 48 and 72 hours after inoculation. A total of 392 transcript-derived fragments (TDFs) were verified in the resistant variety against 380 in the susceptible one. The two sugarcane genotypes showed differential behavior in the number of induced and repressed TDFs along the time-course samplings. Ten out of 23 sequenced TDFs (unique from the resistance variety), showed identity with known plant sequences, mostly related to plant defense mechanisms against pathogens. The cDNA-AFLP technique was effective in revealing changes in the transcription profile within and between contrasting varieties when challenged by ScMV.

Flowering is essential in any breeding programme, particularly in genetic introgression programmes in which flowering synchronism is required. In this work, 16 sugarcane genotypes were evaluated using three different flowering-inductive photoperiod treatments (30 s, 45 s, and 1 min of a daily photoperiod decrease from 12 h 55 of light). Each genotype was planted in 43 L pots (equal proportion of soil, sand, and substrate) with three tillers per pot. Plants with 4 to 6 internodes were placed in a photoperiod facility with three controlled chambers, each chamber containing all 16 genotypes (one treatment per chamber). The temperature range (21°c to 32°c) and humidity were the same for all of the treatments. The flower induction started in September 2010 and ended in April 2011. The plant elongation and flag leaf and inflorescence emergence were recorded and the pollen viability was evaluated by using the iodine staining method. The photoperiod facility provided suitable conditions for flowering, as the plants in the three treatments successfully flowered. The genotypes in the three treatments behaved differently in relation to the date of panicle emergence, with the treatment of 45 s showing better results. The results here presented contribute to synchronise flowering for desired sugarcane crosses, particularly those from introgression programmes between commercial cultivars and species from the Saccharum complex.

The aim of the work was to evaluate the productivity, leaf nutrient content and soil nutrient concentration in maize (Zea mays L.) grown in sequence with black oats (Avena strigosa Schreb.) under Leucaena diversifolia alley cropping agroforestry system (AFS) and traditional management system/sole crop (without trees-TS), after two years of cultivation following a randomized block design. The experiment was carried out in the Brazilian Association of Biodynamic Agriculture, in Botucatu—S?o Paulo, Brazil. Treatments were: control (c), chemical fertilizer application (F), biomass of L. diversifolia alley cropping application (B), biomass of L. diversifolia alley cropping + chemical fertilizer application (B + F). In the second year of management it was observed that black oat yield was higher in treatments B + F and F with significant difference in relation to the others treatments in both systems, followed by treatment B. Between systems, only treatment B showed significant difference, with higher yield value corresponding to AFS, reflecting the efficiency of AFS to promote soil fertility. Maize production presented the second year of cultivation an increasing trend in all treatments in both production systems. This result may be due to the cumulative effect of mineralization and maize straw and oats, along the experiment. How productivity was higher in the AFS system, could also be occurring effect of biological nitrogen fixation, water retention and reduction of extreme microclimate through the rows of L. diversifolia. comparing the AFS and TS, it was observed that the concentration of N in leaf tissue was higher in the AFS treatments, probably due to nitrogen fixation performed through the rows of L. diversifolia, that is a nitrogen fixing tree species. After two years, carbon stocked in soil show higher values in the treatments biomass + fertilizer and biomass application, in both systems, AFS and TS.

The use of batteries in UAVs （unmanned aerial vehicles） has become common due to some advantages in comparison with internal combustion engines such as weight reduction and better power control. However, in these vehicles it is critical to monitor the RUL （remaining useful life） of the batteries. This information can be used, for instance, as a decision support tool to define which missions could be assigned to the UAV until the next battery recharge. This work presents a methodology to predict the RUL of Li-Po （Lithium-Polymer） batteries. The approach uses an extended Kalman filter and an exponential model for the degradation evolution. The proposed methodology uses time series of battery terminal voltages, assuming that the discharge occurs under a constant current condition. Different discharge current levels were *** results showed that the proposed methodology provides good results, despite its simplicity.

Aim: To determine whether bladder functions deteriorate with age. Methods: Data contained in electronic medical record (INFOMED?) were used in this institutional retrospective review. Analysis was done on the urodynamic studies in women over 18 years old conducted between May 2011 and November 2015. Patients with previous history of pelvic surgery or radiotherapy, neurological disease, vaginal prolapse greater than grade I, congenital urogenital malformations, urinary obstructive disease, diabetes, or the use of any medication that could interfere with bladder function were excluded from the analysis. The urodynamic parameters analyzed were the Maximum cystometric capacity (Mcc), Voiding Volume (VV), Maximum Flow (Qmax), Bladder compliance (Bc), Detrusor Pressure at Maximum Flow (PdetQmax), Bladder contractility Index (BcI), Bladder Voiding Efficiency (BVE) and Post-Void Residual Urine Volume (PVR). Patients were further stratified in five groups according to age (A—18 to 40;B—41 to 50;c—51 to 60;D—61 to 70;E—over 70 years old). Results: Out of 3103 urodynamic studies analyzed, 719 were eligible for the study. The average age of patients was 49.3 (+13.2) years old and in all evaluated parameters, statistically significant correlation between age and decline of bladder function was obtained (p conclusions: This study showed a decline in bladder storage function (reduction in Mcc and Bc) and in bladder emptying function (reduction in Qmax, PdetQmax, VV, BcI and BVE with an increase in PVR) with age.
