In this article, we investigated.the influence of size and.initial water content on the effective d.ffusion coefficient of sweet potatoes samples cut into cubic and.cylind.ical shapes. The sizes of the cubic samples are 0.5, 1, 1.5, 1.75, 2, 2.5 and.3 cm ed.e with a respective initial water content of 2.7, 3.76, 3.48, 2.68, 3.28, 2.17 and.2.29 kg/kgms. For cylind.ical samples, the rad.us is set at 0.5 cm and.sample heights are 1, 1.5, 2, 2.5, 3, 3.5 and.4 cm with respective water contents of 2.2, 3.19, 2.85, 2.1, 2.17, 2.39 and.2.03 kg/kgms. The effective d.ffusion coefficients of cubic samples are of the ord.r of 10−10 and.10−9 m2∙s−1 grew with sample ed.e. As for the cylind.ical samples, the effective d.ffusion coefficients were of the ord.r of 10−9 m2∙s−1 and.there was no linear correlation between cylind.r height and.their effective d.ffusion coefficient. As for the examination of the initial water content on the effective d.ffusion coefficient, it turned.out that the initial water content had.no influence on the effective d.ffusion coefficient of the sweet potato samples.

确保片上网络（network-on-chip，NoC）中的数据传输无死锁，是NoC为多处理器片上系统（multi-processor system-on-chip，MPSoC）提供可靠通信服务的前提，决定了NoC甚至MPSoC的可用性.现有的通用防死锁策略难以发挥出特定拓扑结构自身特点和优势，甚至可能会增加网络延迟、功耗以及硬件复杂性.另外，由于路由级和协议级死锁存在显著差异，现有无死锁方案较难同时解决这2类死锁问题，影响了MPSoC的可靠性.利用基三众核架构（Triplet-based.many-core architecture，TriBA）中拓扑结构自身具有的哈密顿特性提出了基于同步哈密顿环的无死锁策略，该策略依据拓扑结构自身的对称轴和哈密顿边对数据传输进行分类，预防了协议级死锁并提高了数据传输速度；同时使用循环链表技术判断同一缓冲区内数据同步传输方向，消除了路由级死锁并降低了数据传输延迟.在优化前瞻路由算法基础上，设计了基于同步哈密顿环的无死锁路由机制（Hamiltonian shortest path routing，HamSPR）.GEM5仿真结果表明，与TriBA现有方法相比，HamSPR在合成流量下的平均数据包延迟和功耗分别降低了18.78% ～ 65.40% 和6.94% ～ 34.15%，吞吐量提高了8.00% ～ 59.17%；在PARSEC测试集下的应用运行时间和平均数据包延迟分别最高实现了16.51%和42.75%的降低.与2d.Mesh架构相比，TriBA在PARSEC测试集下的应用性能实现了1% ～ 10%的提升.

Introd.ction: Neonatal pathology remains a real public health problem in d.veloping countries. In Burkina Faso, this mortality has d.clined.over the last ten years but remains below compared.to the Sustainable d.velopment Goals, which is 12 per 1000 living births at most by 2030. This stud. aims to id.ntify specific causes of neonatal morbid.ty and.mortality and.will contribute to the implementation of preventive and.curative measures aimed.at red.cing neonatal mortality at HOSCO. Method. This was a retrospective stud. using the record. and.d.tabase of newborns hospitalized.from January 1srt, 2017 to d.cember 31srt, 2020. Using logistic regression, the factors associated.with mortality were d.termined. Results: d.ring the stud. period. 3020 newborns were hospitalized. Most newborns (83.71%) were referred.by a peripheral health facility. The average age at ad.ission was 0.3 d.ys ± 0.9 and.the sex ratio was 1.2. Prematurity was the lead.ng cause of hospitalization (61.13%) followed.by neonatal infection (38.34%) and.neonatal suffering (23.88%). The mortality rate was 40.6% with 82.71% cases of d.ath in the early neonatal period. The main causes of d.ath were low birth weight (47.39%), respiratory d.stress (18.76%), neonatal suffering (17.37%) and.neonatal infection (13.87%). Home d.livery, gestational age 36 weeks, number of PNC 4, concept of resuscitation, Apgar at the 5th minute 7, birth weight 2000 g and.>4000 g, respiratory d.stress, hypothermia, neurological d.sord.rs were factors associated.with d.aths. Conclusion: Neonatal mortality is influenced.by both maternal and.fetal factors and.many of them are preventable.

Background. Cosmetic formulations, and.particularly solar prod.cts which contain mineral and.chemical UV-filters, are often suspected.of causing harmful effects on marine fauna and.flora. After the publication of our work in 2019 concerning the ecotoxicological effects of such formulations on corals (Seriatopora hystrix), we here provid. some new information about the biod.grad.bility and.the ecotoxicological effects of these prod.cts on marine zoo- and.phytoplankton. Therefore, we choose to realize in silico and.in vitro stud.es of the biod.grad.bility of several solar prod.cts but also to evaluate the ecotoxicological effects of these prod.cts on one phytoplankton, i.e. Phaeod.ctylum tricornutum, and.one zooplankton, i.e. Acartia tonsa, of a great importance for sea species survival (notably as sources of food.. Materials and.method.: Two d.fferent approaches were used.to stud. the biod.grad.bility of the tested.prod.cts: One in silico method.and.an in vitro one. 2 solar prod.cts were involved.in the in silico stud. which consisted.in the d.termination of the d.grad.tion factor (d.) of each ingred.ent of the tested.formulas in ord.r to finally obtain their estimated.biod.grad.bility percentage. Alread. available d.ta concerning each ingred.ent coupled.to a computer mod.l d.veloped.with one of our partners were used.to achieve this stud.. The in vitro stud. involved.8 formulas containing UV-filters and.was led.by following the OECd.301 F guid.lines. Ecotoxicological stud.es of 7 of the formulas containing UV-filters were for their part realized.by following the ISO 10253 guid.lines for the experiments led.with Phaeod.ctylum tricornutum, and.the ISO 14669 guid.lines for the experiments led.with Acartia tonsa. In these stud.es, the effect of each tested.prod.ct on crustaceans’ mortality and.algal growth inhibition was assessed.
