- 感官科学 感官科学
- 消费者研究 消费者研究
背景情况:
- 由于COVID-19流行病的限制,感官评估转向了远程方法.
- 家庭使用测试 (HUT) 与技术集成,实现了场外样本评估.
- 显而易见的是,需要在地理上灵活的感觉测试方法.
研究的目的:
- 为了比较中央位置测试 (CLT),传统家庭使用测试 (HUT) 和无接触家庭使用测试 (N-HUT) 的感觉评估结果.
- 评估N-HUT用于收集感官概况和情绪反应的有效性.
- 确定N-HUT是否可以克服CLT和HUT的区域限制.
主要方法:
- 通过当地社区网站招募参与者进行三个测试条件:CLT (n=104),HUT (n=120) 和N-HUT (n=111).
- 通过HUT和N-HUT的配送服务提供咖啡样品.
- 使用智能手机进行N-HUT感官数据收集,包括接受度,感官档案和情绪反应.

01:14Assessing Body Temperature - Oral
784
Here are the steps to accurately measure oral temperature using an electronic thermometer:
Step 1:
Start by practicing proper hand hygiene to prevent the spread of microorganisms.
Step 2:
Take the thermometer out of the charging unit, switch it on, and wait for the ready sign.
Step 3:
Gently slide the probe cover until a click is heard. This simple action prevents cross-contamination and ensures the correct placement of the probe cover.
Step 4:
Instruct the patient to open their mouth and place...

When the quality of water for concrete preparation is uncertain, its impact on the setting time of cement and compressive strength of mortar is assessed by comparison with de-ionized or distilled water benchmarks. American Society for Testing and Materials (ASTM) C1602 requires the setting times to be within 90 minutes of the control, British Standard (BS) 3146:1980 allows a 30-minute variance in the initial setting, while British Standards European Norm (BS EN) 1008 specifies initial setting...
