Poor exocarp colour development is a common postharvest problem for early harvested “Hass” avocado fruit during ripening, which affects fruit quality and consumer preference. Therefore, measures to improve “Hass” avocado fruit colour developments are of great importance in the industry. This study investigated the effectiveness of postharvest methyl jasmonate treatment to improve early matured “Hass” avocado fruit exocarp colour during ripening. The results showed that T1 (10 μmol∙L−1) and T2 (100 μmol∙L−1) MeJA treatment increased visual colour, and decreased objective colour parameters (L*, C* and h˚) during ripening when compared with control fruit. Moreover, MeJA treated “Hass” avocado fruits had lower total chlorophyll content and higher total anthocyanin and cyanidin-3-O-glucoside concentration during ripening. In conclusion, “Hass” avocado fruit post-harvest treated with either T1 (10 μmol∙L−1) or T2 (100 μmol∙L−1) MeJA concentration improved exocarp quality attributes such as colour parameters (L*, C* h˚ and visual colour) and pigments (total anthocyanin and cyanidin-3-O-glucoside) during ripening, therefore, can be recommended for avocado fruit.

对高水分稻谷进行了间歇干燥,研究干燥段数和缓苏温度对稻谷干燥品质的影响,并应用隶属度分析法对干燥品质进行综合评价。结果表明,间歇干燥可缩短干燥时间,与连续干燥40℃缓苏组相比,4段60℃缓苏组的干燥时间缩短了26.36%。间歇干燥可显著地降低干燥后稻谷的爆腰率,提高整精米率。高温缓苏(50、60℃)时,缓苏温度对整精米率影响优于干燥段数。热风干燥后稻谷的脂肪酸值增加,发芽率降低。隶属度分析法得出优化后的干燥条件为:干燥段数为2段,缓苏温度为60℃,综合分为最大值0.80。

Purpose: Defects aro und the distal one third of the leg and ankle are difficult to man age by con servative measures or simple split thickness skin graft. Distally based peroneus brevis muscle flap is a well described flap for such defects. Methods: This is a retrospective analysis conducted on 25 patients with soft tissue and bony defects of distal third of lower leg and an kle, which were treated using distally based per on eus brevis muscle flap from January 2013 to January 2018. Information regarding patient demographics, etiology, size and location of defects and complications were collected. All patients were followed up for at least 3 months after surgery. Results: There were 21 males and 4 females with the mean age of 39 (5-76) years. The most comm on cause of injuries was road traffic accident, followed by complicated open injury. The average size of defects was 20 (4—50) cm^2. The mean operating time was 75 (60-90) min for flap harvest and inset. We had no patient with complete loss of the flap. Five patients (20%) had marginal necrosis of the flap and two patie nts have graft loss due to un derlyi ng hematoma and required sec on dary split thickness skin grafting. Conclusion: The distally based peroneus brevis muscle flap is a safe optio n w 让h reliable an atomy for small to moderate sized defects following low velocity injury around the ankle. The commonest complication encountered is skin graft loss which can be reduced by primary delayed grafting.

利用不同的干燥方式对稻谷进行干燥,降至安全水分含量12%(湿基),测定干燥后稻谷的整精米率(head rice yield,HRY)、脂肪酸值以及RVA特征值。结果表明:对于连续干燥作业,缓苏过程中存在一个临界缓苏时间,达到临界缓苏时间能显著提高整精米率,且干燥温度越高,该临界缓苏时间的出现越明显;但干燥温度高于60℃,且一次降水幅度不小于9.4%,缓苏温度与干燥温度相同时,通过延长缓苏时间,整精米率难以达到70%;对于干燥-通风联合作业,干燥温度高于60℃,且缓苏温度不低于干燥温度时,虽能保持较高整精米率(>72%),但稻米的RVA特征值(峰值黏度、最低黏度、崩解值、最终黏度、回生值)总体上随着干燥温度、缓苏温度的升高和缓苏时间的延长而增加,且存在一些波动,干燥温度、缓苏时间对其影响显著性低于缓苏温度。两种干燥方式的脂肪酸值都存在不同于恒低温干燥持续增加的变化趋势。

Though several maize varieties have been developed and introduced over the years in Ghana, farmers still face challenges of access to quality seed maize. Among the major constraint is lack of proper drying systems to guarantee quality of seed produced. As in most parts of Africa, drying of maize in the open, on bare ground along shoulders of roads is still a common practice in Ghana. In this study, a 5-tonne capacity hybrid solar biomass dryer was developed for drying maize for seed and food/feed in Ghana. Effect of air temperature in the dryer on the physiological quality and germination of maize kernels was investigated. Maize grains were dried in the open sun simulating farmers practice and using the dryer at 4 varying levels (L1, L2, L3 and L4) with corresponding heights (0.6 m, 1.2 m, 1.8 m and 2.4 m, respectively) from the ground. Harvested maize at 22.8% moisture content was dried at the varying levels until reaching the final desired moisture content of 12.8% ± 0.2% (wb). Results showed that, air temperatures in the dryer increased in accordance with height with lowest mean temperature of 44.4°C ± 4.6°C recorded at L1 and mean maximum of 52.8°C ± 5.4°C at L4. Drying temperatures recorded at L1 - L3 and ambient had no significant effect (p < 0.05) on kernel damage and viability. Drying conditions at L1-L3 were considered optimum (<50°C) for kernel drying compared to the topmost tray, L4. Kernel stress crack index (multiple and checked) was therefore reduced on average by 14% while kernel germination increased by 33%. This satisfies the dryer’s potential to be used for commercial drying of maize grains for seed production for smallholder farmers in Ghana.

以不同干燥温度、相对真空度为因素对稻谷进行真空干燥-常压缓苏实验,研究其干燥后稻米爆腰增率、整精米率及蒸煮质构品质变化,分析其相关性,并通过扫描电镜观察不同干燥条件对稻谷籽粒显微形态的影响。结果表明:干燥温度和真空度对稻谷干燥后爆腰增率及整精米率影响极显著(p<0.01)。干燥温度、真空度且二者交互作用对米饭质构特性有极显著影响(p<0.01)。经过对稻谷干燥后各品质相关性分析,得出稻谷爆腰增率与其蒸煮硬度、胶黏性及胶着性呈极显著的正相关性(p<0.01),稻谷整精米率与硬度、胶黏性、胶着性呈极显著负相关性(p<0.01),且二者均与弹性、咀嚼性及内聚性没有相关性。干燥温度越高,相对真空度越大,干燥速率越大,淀粉粒与蛋白质的结合度越小,结构越稀松,干燥裂纹越粗大,数量越多。

近年来,人类活动影响导致水生态系统遭到破坏,水生生物多样性锐减,水生态功能严重退化并影响人类健康。而生物多样性是维持生态平衡的基础,因此,对水生生物进行监测是开展水生态环境管理和保护的前提。目前,传统的水生态研究主要依赖形态学生物监测,以及通过直接观察、显微镜和生物声学收集数据。然而传统形态学生物监测存在费时费力、成本高、物种分辨度低等诸多缺陷,无法在流域开展大规模、高频率的水生态监测。
