Mapping of QTLs for Dehiscence Length at Basal Part of Thecae in Rice Based on TD70/Kasalath RIL Population

A population of 240 recombinant inbred lines （RIL） was derived from a cross between Japonica rice cultivar TD70 and Indica cultivar Kasalath, and their linkage map including 141 SSR markers was used to locate the QTLs controlling the length of dehiscence at the basal part of thecae （LDBT）. Then, the correlations between LDBT and other agronomic traits of rice were analyzed. Two QTLs con- trolling LDBT were mapped on chromosome 6 and 8, respectively, qLDBT6 was mapped between RM3 and RM3628 markers on chromosome 6 with a LOD value of 3.23, contribution rate of 6.18% and additive effect of 17.74%. qLDBT8 was mapped between RM1376-RM4085 markers on chromosome 8 with a LOD value 2.95, contribution rate of 8.00% and additive effect of 20.09%. This domain probably had a relationship with the sterility of rice. The LDBT of RILs had extremely signifi- cant positive correlations with flag leaf width, 1 000-grain weight, grain width, grain length and grain thickness, but no significant correlations with other agronomic traits, such as plant height, heading date, tiller number, flag leaf length, average and the maximum temperature during heading period or rice.

Synthesis and ceramization of polycarbosilane containing beryllium

Polycarbosilane containing beryllium(BPCS) precursors was prepared by the reaction of polycarbosilane(PCS) with beryllium acetylacetone(Be(acac)2).The analysis of structures and components of BPCS demonstrates that their main structures are basically the same as PCS.Ceramization of BPCS precursors shows that BPCS precursors are organic below 600 °C and inorganic at 800 °C.At 1400 °C,BPCS precursors convert into silicon carbide ceramics.The ceramization of different beryllium content precursors were studied,which show that beryllium plays an important role in the inhibition of crystalline grain growth of β-SiC at high temperature and it can adjust the dielectric constant of silicon carbide ceramics.

Study on oil–source correlation by analyzing organic geochemistry characteristics: a case study of the Upper Triassic Yanchang Formation in the south of Ordos Basin, China

In the south of the Ordos Basin, the oil source of the Upper Triassic Yanchang Formation is confused all the time, which affects further exploration. In this study, oil sources from the oil layers of Ch6, Ch8 and Ch9 are all analyzed and confirmed. Through their carbon isotope value and biomarkers, characteristics of crude oils from the Yanchang Formation are analyzed. Then, the oil–source relation is discussed, with the source rocks' features.Finally, the oil–source relation is calculated through cluster analysis. It is believed that the oils from the Yanchang Formation deposit in a similar redox environment, with weak oxidation–weak reduction, and have all entered maturity stage. Ch9 crude oil is more mature than crude oils from Ch6 and Ch8, and has more advanced plants and fewer algae. Gas chromatography(GC) and gas chromatography–mass spectrometry(GC–MS) analysis show that crude oils from Ch6 and Ch8 may come from Ch7, and Ch9 crude oil may not. Cluster analysis displays that crude oils from Ch6 and Ch8 have closer squared Euclidean distance with Ch7 source rocks than Ch9 crude oil does,indicating crude oils from Ch6 and Ch8 stem from Ch7 source rocks. And Ch9 crude oil has rather close squared Euclidean distance with Ch9 source rocks, illustrating Ch9 crude oil may be from Ch9 source rocks. This research may provide the theoretical basis for the next exploration deploy in the south of Ordos Basin.

Effect of Climatic Factors on the Radial Growth of Teak （Tectona grandis L.F.） in Parakou and Tchaourou Districts in Northern Benin

Climatic factor＇s effect was studied on the radial growth of teak （Tectona grandis L.F.） by using the stem analysis of 36 trees distributed in 6 plantations in Parakou and Tchaourou districts in northern Benin. The results showed that the plantations of Parakou were in general more productive than those of Tchaourou. The annual average growth was estimated in the first five years at 0.86 cm/year for Parakou and 0.76 cm/year at Tchaourou. The analysis of the radial growth showed that a significant percentage of the variance was allotted to the growth model. It follows that a big part of the ring width was predetermined before the intervention of the other factors, in particular the climatic conditions. The percentage of the variance related to the climatic conditions was thus more reduced for the plantations of Tchaourou than those of Parakou. The radial growth was influenced by the conditions of humidity （evapotranspiration, humidity and rain） of February to May on the one hand and those from August to October on the other hand.

Problems in Post-crisis Employment for Migrant Workers Remain Unsolved

As indicated by a survey of 105 villages in 19 provinces and cities, the 2008 international financial crisis had a serious impact on migrant workers＇ employment, which is prominently manifested in their earlier return to their hometowns, the dismissal of 20 percent of migrant workers from their jobs and a considerable decline in their wages. Thanks to a series of policies the state adopted to ensure growth and expand consumption, migrant workers soon got re-employed. However, some deep-rooted problems surrounding the issue of migrant workers＇ empoyment came to light as a result of this crisis. These problems need to be solved on an urgent basis, though it will involve a considerable amount of hard work over an extended period of time. While this will require a combination of transitional measures and long-range strategies, the employment of migrant workers should also be incorporated as a fundamental part of the undertaking to ensure economic growth, adjusting the industrial structure, transforming the development mode and pushing forward with the reform.

Characteristics of carbonate cementation in clastic rocks from the Chang 6 sandbody of Yanchang Formation, southern Ordos Basin

Densification of reservoir is an important factor that restricts oil and gas exploration from low porosity and extra-low permeability reservoirs. Carbonate cementation was heavily developed in Chang 6 sandbody, a facies of underwater distributary channel in delta front, of Upper Triassic Yanchang Formation in Fuxian area, southern Ordos Basin, and the cementation is one of the major factors that affect quality of reservoir. Based on the macro-microcosmic petrology and geochemistry features, the genesis of densification of carbonate-cemented reservoir was systematically discussed. The carbonate cementation can be classified into endogenous and exogenous, and the essential differences between them are that they were formed in different fluids and in different diagenesis periods. With the aid of identification of thin sections, analyses on electron probe, trace and rare-earth elements, carbon and oxygen isotope, we propose that the endogenous fluid for cementation came from the rock itself during early diagenetic stage. The minerals related to endogenous fluid had good shapes. The reservoir property was enhanced with porosity increasing by 3%-8% because of later dissolution by endogenous fluid. The exogenous fluid might be water combining with CO 2 , likely released from organic matter-rich mudstone. Calcite cement, in form of substrate cementation, was precipitated from the fluid and filled in the remaining pores of sandstones in late diagenetic stage as variations of physical and chemical conditions. The exogenous cement reduced rock porosity, damaged reservoir property, affected some oil enrichment, and seriously caused Chang 6 reservoir densification. Some of the dense layers that formed on top of sandbody could have served as diagenetic traps, and thus the exogenous cementation area could be favorable for oil exploration.

Zircon SHRIMP U-Pb age and geological implications of tuff at the bottom of Chang-7 Member of Yanchang Formation in the Ordos Basin

A table tuff interlayer at the bottom of Chang-7 Member of Yanchang Formation,the Ordos Basin,may serve as an indicator for stratigraphic division and correlation.In this study,zircon SHRIMP U-Pb dating was performed on the tuff at the bottom of Chang-7 Member using samples from wells Luo-36 and Zhuang-211 in the southwest of the basin,which yielded weighted average 206Pb/238U ages of 241.3±2.4 and 239.7±1.7 Ma,respectively.The cathodoluminescence images and the U/Th element ratio of tuff indicate that the zircons are magmatogenic and their ages represent that of the sedimentation age of the tuff at the bottom of Chang-7,which is 239.7–241.3 Ma in age.This finding confirms presence of the Middle Triassic strata at the bottom of Yanchang Formation.Taking previous findings into account,we suggest restricing the Late Triassic Yanchang Formation sensu stricto to the interval from Chang-7 to Chang-1 and assigning the interval from Chang-10 to Chang-8 as the Tongchuan Formation.The tuff at the bottom of the Chang-7 Member of Yanchang Formation represents the sedimentary response to the Qinling orogenic event in the early Indosinian.This tectonic event resulted in major changes in paleogeomorphology and the sedimentary environment of the lake basin during deposition of the Yanchang Formation.During this period,extremely favourable conditions were present for subsequent hydrocarbon generation and pooling of lake basin.

Extended anterolateral thigh pedicled flap for reconstruction of trochanteric and gluteal defects： A new 8： innovative approach for reconstruction

Descending branch of the lateral circumflex femoral artery （LCFA） is commonly used pedicle for anterolateral thigh （ALT） flap. Oblique branch of LCFA is an alternative pedicle that can be used in microvascular surgery. According to review of literature and to the best of our knowledge we could not find the use of oblique branch of LCFA as a pedicle of the ALT flap in regional soft tissue reconstruction. Here we presented a case of a 55-year-old man sustaining soft tissue injury and wound over the left trochanteric and gluteal region following a road traffic accident, who was treated by the use of extended ALT pedicle flap with oblique branch of LCFA as the pedicle for reconstruction of soft tissue defect in trochanteric and gluteal regions with successful outcome.

The heart rate - breathing rate relationship in aquatic mammals： A comparative analysis with terrestrial species

Aquatic and semi-aquatic mammals, while resting at the water surface or ashore, breathe with a low frequency （f） by comparison to terrestrial mammals of the same body size, the difference increasing the larger the species. Among various interpretations, it was suggested that the low-f breathing is a consequence of the end-inspiratory breath-holding pattern adopted by aquatic mammals to favour buoyancy at the water surface, and evolved to be part of the genetic makeup. If this interpretation was correct it could be expected that, differently from f, the heart rate （HR, beats/min） of aquatic and semi-aquatic mammals at rest would not need to differ from that of terrestrial mammals and that their HR-fratio would be higher than in terrestrial species. Literature data for HR （beats/min） in mammals at rest were gathered for 56 terrestrial and 27 aquatic species. In aquatic mammals the allometric curve （HR=191 .M^18; M= body mass, kg） did not differ from that of terrestrial species （HR=212.M^-0.22） and their HR-fratio （on average 32±5） was much higher than in terrestrial species （5±1） （P〈0.0001）. The comparison of these HR allometric curves to those forfpreviously published indicated that the HR-fratio was body size-independent in terrestrial species while it increased significantly with M in aquatic species. The similarity in HR and differences in f between aquatic and terrestrial mammals agree with the possibility that the lowfof aquatic and semi-aquatic mammals may have evolved for a non-respiratory function, namely the regulation of buoyancy at the water surface [Current Zoology 61（4）： 569-577, 2015].
