Opis:
Honania complicidentata and Tsiyuania simplicidentata are pareiasaur taxa based on material from the Shangshihezi Formation of Jiyuan, Henan Province, China that were earlier designated as nomina vana. Based on the study of new material, and the reexamination of old specimens, we determine that the pareiasaur material from Jiyuan represents a single species that differs from all known species from other localities. Thus, we resurrect the name H. complicidentata for the material from Jiyuan. H. complicidentata is characterized by maxillary teeth with high crowns, dentary teeth slightly posteriorly inclined compared to the dentary dorsal margin, nearly all preserved marginal teeth have a cusped cingulum on the lingual surface, and humerus without an ectepicondylar foramen. Phylogenetic analysis shows Honania is more basal than Shansisaurus and Shihtienfenia from the Sunjiagou Formation of China.

Opis:
A new troodontid dinosaur, Xixiasaurus henanensis gen. et sp. nov., from the Upper Cretaceous Majiacun Formation of the Xixia Basin, Henan Province, is erected, based on a partial skull. It is characterized by bearing 22 maxillary teeth, a distinct opening on the lateral surface of the base of nasal process of the premaxilla, the rostral end of the upper jaw forming a tapered U−shape, and the mandibular symphyseal region slightly inflected medially. Xixiasaurus is most closely related to the Mongolian Byronosaurus among troodontids. Byronosaurus, Urbacodon, and Xixiasaurus may form a new clade, suggesting an endemic radiation of troodontids across Asia, including multiple taxa without dental serrations. The discovery of Xixiasaurus in the Xixia Basin may imply that the Xixiasaurus−bearing Majiacun Formation is Campanian in age.

Opis:
A three-dimensional computational model, solving Reynolds equations with the ke turbulence closure, has been presented to simulate the flow field in an open channel near a side-discharge channel. The purpose of this study was to exam this model's applicability for simulating the three-dimensional recirculation velocity field in the vicinity of the side discharge channel. The numerical simulations show that both the height and length of the recirculation zone were correctly predicted when compared with laboratory measurements. The predicted trend of the shape of the recirculation zone under different flow conditions agrees with experimental data. It was confirmed that the SMART upwinding scheme performs better than QUICK and HYBRID schemes, since it induces less numerical diffusion and no oscillations. It was found in this study that the SMART scheme needs some minor modifications for complex flow computations.

Opis:
This paper reported characteristics of aerial photographs of mainland China taken by U-2 spy planes, which were archived and made public in NARA II of USA, and discussed the possibility to use them for environmental studies. U-2 photographs of China, which have high ground resolution of about 75cm were mainly taken in the first half of 1960s. Large amount of photographs including oblique photos as well as overlapped vertical photos covers vast range of China and enable us to use for detailed stereoscopic interpretation as well as creating ortho photos and digital surface models. Case studies in Loess Plateau (Shaanxi Province, China) showed the possibility of detailed observations of land features and land uses such as cave dwellings, check dams, agricultural terraces and cultivated crops, as well as estimation of the amount of gully erosion. In the process of archival research in NARA II, however, various inconveniences were found and improvement of retrieval system were desired.
W artykule opisano charakterystykę zdjęć lotniczych Chin kontynentalnych wykonanych przez samoloty szpiegowskie U-2, które zostały zarchiwizowane i upublicznione w NARA II w USA, a także omówiono możliwości wykorzystania ich w studiach ochrony środowiska. Fotografie lotnicze z samolotów U-2, wykonanych nad terytorium Chin, mają wysoką rozdzielczość terenową, wynoszącą około 75 cm, zostały wykonane głównie w pierwszej połowie lat sześćdziesiątych XX wieku. Duża liczba zdjęć, w tym zdjęcia skośne, a także zdjęcia pionowe w pokryciu stereoskopowym obejmują znaczną powierzchnię Chin. Pozwalają one na szczegółową interpretację stereoskopową, jak również na tworzenie ortozdjęć i cyfrowych modeli terenu. Studia przypadków na płaskowyżu lessowym (prowincja Shaanxi, Chiny) wskazały na możliwość szczegółowych obserwacji cech terenu i użytkowania gruntów, takich jak mieszkania w jaskiniach, tamy kontrolne, tarasy rolnicze i pola uprawne, a także oszacowanie wielkości erozji. W procesie korzystania z archiwalnych zasobów zdjęć w NARA II (National Archives and Records Administration - USA) stwierdzono różne niedogodności i pożądane było ulepszenie systemu pobierania zdjęć.

Opis:
Recent developments in Taiwan toward the technology intensive country, the employment of cost effective foreign labors by shipping companies, the widespread of universities and the internationalization of shipping industries propose considerable threats on the quality assurance of maritime education. A resultant crisis for lacking on-board seafarers with managerial levels has urged the consolidation of governmental, private and educational organizations in the attempts to further improve the quality of maritime education and to promote the on-board career incentives. The process from the formulation of problems to the implementation of strategies undertaken by the National Kaohsiung Marine University (NKMU) is reviewed. A chain reaction initiated from the degradation of students’ entry performances due to the widespread of universities has formed a viscous cycle leading to the outsourcing of foreign human resources by shipping industry. Strategies in the aspects of course reform, joint ventures of lectureship with shipping industry, pre-courses for students’ extended career plans and the establishment of educational center that consolidates the departments of navigation, marine engineering and fishery in NKMU are illustrated.

Opis:
It is important to evaluate the deformation and failure of sandstone in the foundation engineering of coast, river bank and lake shore. While the deformation and failure of sandstone is a comprehensive result of energy release and dissipation, and energy release is the internal reason which leads to global failure of the sandstone. The experimental analysis is conducted on the character of energy revolution of the sandstone specimen by rating loading and unloading, and the catastrophe model is followed in analyzing elastic strain energy accumulation and release in rock deformation and failure. The index based on elastic energy release is proposed to assess the rock brittleness. It is found that increasing water content is to relieve energy release and catastrophe failure of the rock specimen, and weakening the capacity of elastic energy storage. The peak and residual values of elastic energy are raised as the confining pressure increases, and the post-peak released energy decreases progressively. The confining pressure strengthens energy storage and inhibits energy release of the rock specimen, and saturation of rock will weaken this inhibit effect. The brittleness index decreases with increasing confining pressure as the rock specimen transforming from brittle to ductile.

Opis:
Pyrolysis is potentially an effective treatment of oily sludge for oil recovery, and the addition of a catalyst is expected to affect its pyrolysis behavior. In the present study, Fe/Al-pillared bentonite with various Fe/Al ratios as pyrolysis catalyst is prepared and characterized by XRD, N2 adsorption, and NH3-TPD. The integration of Al and Fe in the bentonite interlayers to form pillared clay is evidenced by increase in the basal spacing. As a result, a critical ratio of Fe/Al exists in the Fe/Al-pillared bentonite catalytic pyrolysis for oil recovery from the sludge. The oil yield increases with respect to increase in Fe/Al ratio of catalysts, then decreases with further increasing of Fe/Al ratio. The optimum oil yield using 2.0 wt% of Fe/Al 0.5-pillared bentonite as catalyst attains to 52.46% compared to 29.23% without catalyst addition in the present study. In addition, the addition of Fe/Al-pillared bentonite catalyst also improves the quality of pyrolysis-produced oil and promotes the formation of CH4. Fe/Al-pillared bentonite provides acid center in the inner surface, which is beneficial to the cracking reaction of oil molecules in pyrolysis process. The present work implies that Fe/Al-pillared bentonite as addictive holds great potential in industrial pyrolysis of oily sludge.

Opis:
African swine fever virus (ASFV) causes feverous and hemorrhagic disease of domestic pigs and European wild boars with high mortality, yet no commercial vaccine is currently available. Several ASFV strains with natural deletion or gene-targeted knockout of multiple MGF360 and MGF505 genes are attenuated in vitro and in vivo, and can offer full protection against homologous challenge. However, the mechanisms underlying the protection are not fully understood. This study aims to investigate the effects of MGF360-12L of ASFV-SY18 on the cGAS-STING signaling pathway and explore the potential mechanisms. We identified that ASFV-SY18 MGF360-12L could inhibit cGAS-STING, TBK1, or IRF3-5D-stimulated IFN-β expression and ISRE activation. Specifically, MGF360-12L inhibits both the activation of PRD(III-I) in a dose-dependent manner, and suppresses the exogenous expression of TBK1 and IRF3-5D. MGF360-12L could block NF-κB activation induced by overexpression of cGAS-STING, TBK1, IKKβ. Downstream of the IFN-β signaling, MGF360-12L blocks the ISRE promoter activation by reducing total protein level of IRF9. Moreover, MGF360-12L protein can inhibit IFN-β-mediated antiviral effects. In conclusion, our findings suggest that MGF360-12L is a multifunctional immune-evasion protein that inhibits both the expression and effect of IFN-β, which could partially explain the attenuation of relevant gene-deleted ASFV strains, and shed light on the development of efficient ASFV live attenuated vaccines in the future.
