漫论余华小说的生命意识

余华注重刻画孤独，展示人生鬼态，揭示出人性的丑恶。但又充满了家园之恋、故土情结和对生命的哲理性思考。在揭示一定的宿命主题时，以抒情的笔调讴歌了生命的价值，用流水的意象表现对生命的终极关怀，那种关怀是热烈、饱满而又奔放的。

学前教育专业教法课程的综合化趋势

师范高职学前教育专业主要培养幼儿园一线教师,教法课程是该专业学生的必修课程。依据现阶段幼儿园的课程模式与教学模式,以形成学生从事幼儿园教育教学活动的能力作为教学目标,师范高职学前教育专业设立了“五大领域”教法课程。“五大领域”教法课程的内容既相互联系又相互作用,在教育目标、内容、方式上呈现出综合化趋势。在教法课程的教学实践中,提倡单科教法服务于全局、服务于幼儿园教学需要理念并对学生实施“五大领域”模拟教学综合考核。

Influence of deep sea environment on the performance of a LiFePO<Subscript>4</Subscript> polymer battery

A lithium-ion polymer battery cell is an ideal energy source for underwater vehicles due to its high energy density and small volume. However, the performance of lithium-ion batteries in a 10 000 m deep sea is still unknown and is of particular concern in the design of 10 000 m autonomous remote vehicles (ARVs). In this paper, we explore how the external characterizing parameters of a LiFePO₄ polymer battery during discharge are affected by a high pressure of 100 MPa and low temperature of 3 °C for simulating the conditions experienced in a 10 000 m deep sea environment. An unscented Kalman filter (UKF) algorithm is applied to estimate the state of charge (SoC) of a battery to investigate the influence of high hydrostatic pressure on SoC estimation due to changes in parameters. The results indicate that the LiFePO4 polymer battery works under 100 MPa hydrostatic pressure, but its parameters change obviously and influence SoC estimation. SoC estimation accuracy was improved through compensating the functions of open circuit voltage (OCV) versus the state of charge (OCV-SoC) of the battery in a 100 MPa hydrostatic pressure and a low temperature environment.

Cognitive-enhancing effects of hydrolysate of polygalasaponin in SAMP8 mice

Objectives

The aim of the study is to evaluate the cognitive-enhancing effects of hydrolysate of polygalasaponin (HPS) on senescence accelerate mouse P8 (SAMP8) mice, an effective Alzheimer’s disease (AD) model, and to research the relevant mechanisms.

Methods

The cognitive-enhancing effects of HPS on SAMP8 mice were assessed using Morris water maze (MWM) and step-through passive avoidance tests. Then N-methyl-d-aspartate (NMDA) receptor subunit expression for both the cortex and hippocampus of mice was observed using Western blotting.

Results

HPS (25 and 50 mg/kg) improved the escape rate and decreased the escape latency and time spent in the target quadrant for the SAMP8 mice in the MWM after oral administration of HPS for 10 d. Moreover, it decreased error times in the passive avoidance tests. Western blotting showed that HPS was able to reverse the levels of NMDAR1 and NMDAR2B expression in the cortex or hippocampus of model mice.

Conclusions

The present study suggested that HPS can improve cognitive deficits in SAMP8 mice, and this mechanism might be associated with NMDA receptor (NMDAR)-related pathways.
