科学领域:
- 环境健康 环境健康
- 城市规划 城市规划
- 儿科 儿科 儿科
背景情况:
- 撒哈拉以南非洲 (SSA) 城市的儿童在小学中面临着严重的环境污染.
- 关于空气和噪音污染水平,SSA学校环境中的不平等和决定因素的数据有限,特别是在快速城市化地区.
研究的目的:
- 为了评估大阿克拉,SSA的小学中的空气和噪音污染.
- 探索这些学校周围污染水平的决定因素.
- 为了评估儿童的噪音烦.
主要方法:
- 在90个校园里,为期一周的细颗粒物 (PM2.5),黑碳 (BC) 和声压水平的测量.
- 评估校园的特点 (表面类型,绿色,道路附近).
- 用于检查污染物和校园因素之间的关联的通用添加模型;进行噪音烦调查.

01:19Factors Affecting Pulmonary Ventilation
2.8K
Besides the pressure difference between the external environment and the lungs, the airflow rate and ease of pulmonary ventilation are also influenced by three other factors: surface tension of the fluid in the alveoli, compliance of the lungs, and airway resistance.
Alveolar Surface Tension
The alveolar fluid lines the luminal surface of the alveoli and exerts a force called surface tension. This force is caused by the polar water molecules in the liquid being more strongly attracted to each...

Asthma is a chronic respiratory ailment that requires careful management due to its varying symptoms and influencing factors. It is characterized by airway inflammation, bronchial hyperresponsiveness, and reversible airflow obstruction, leading to symptoms like wheezing, shortness of breath, chest tightness, and coughing. The symptom frequency and intensity may vary considerably over time. It is also linked to immune system responses to allergens and irritants, highlighting the complex...
