In the summer of 2002, field crews from the Burpee Museum of Natural History in Rockford, IL recovered the partially articulated skeleton of a seven meter long tyrannosaurid from the Hell Creek Formation (Uppermost Maastrichtian) of Carter County, MT. Nicknamed Jane;the specimen (BMR P2002.4.1) is represented by 145 skeletal elements including a nearly complete but disarticulated skull. Cranial bones of BMR P2002.4.1 (Jane) closely resemble those of CMNH 7541, a con-

Catalytic Performance in CO Hydrogenation Over SiO_2-Supported Ru-M (M=Co, Fe,Mo,Ni,Rh,Mn and Cr) Bimetallic Cluster-derived Catalysts

The bimetallic Ru-M (M=Co,Fe,Ni,Mo, Rh,Cr, Mn) catalysts were prepared from SiO_2-supported bimetallic carbonyl clusters, and it was found that the Ru-Co, Ru-Fe and Ru-Mo bimetallic carbonyl cluster-derived catalysts showed higher activity and selectivity for oxygenates such as C_1-C_5 alcohols in CO hydrogenation,in contrast to catalysts prepared from SiO_2-supported homometallic Ru and Co carbonyl clusters. In situ FT-IR studies revealed that the bands at 1584 and 1555 cm^(-1) species were intermediates to produce methanol and higher oxygenates,and at higher temperatures the 1584 cm^(-1) species could react with alkyl to form 1555 cm^(-1) species. By the surface chemical reaction and the IR study of isotopic molecules,it was suggested that 1584 and 1555 cm^(-1) were assigned to surface formyl and acetyl species.

Cocoon samples were collected from fifty-two mulberry gardens with high, intermediate, and low silkworm cocoon productivities in the lower-middle reaches of the Yangtze River in the six China’s provinces of Jiangsu, Jiangxi, Anhui, Fujian, Hunan, and Hubei to determine the transformation efficiency of S from mulberry leaves to silkworm cocoons, and to evaluate the sulfur cycle (uptake and output) in the mulberry leaf-silkworm cocoon system with typical mulberry gardens in the lower-middle reaches of the Yangtze River in China. The transformation efficiency of sulfur (TES) from mulberry leaves into silkworm cocoons in the high-productivity mulberry gardens was significantly lower (P ductivity gardens. For the high-productivity mulberry gardens the TES from mulberry leaves into the cocoon shells was significantly higher (P d mulberry gardens. Producing 1 kg dry cocoon in mulberry gardens required uptake of about 20 g S, however 1 kg of dry cocoon only removed about 4 g S. Therefore, recycling of these organic wastes with silkworm cultivation was important for sulfur balances.

Regional Moisture Source Changes Inferred from Late Holocene Stable Isotope Records

引用

Advances in Atmospheric Sciences 2008年第6期25卷 1021-1028页

作者： Zhonghui LIU Andrew C. G. henderson Yongsong HUANG department of Geological Sciences Brown University Providence RI 02912 USA Environmental Change Research Centre Department of Geography University College London 26 Bedford Way London WCIH OAP UK

Qinghai Lake, China, is located near the northern limit of the East Asian summer monsoon （EASM） and thus is an ideal region for studies of past monsoonal changes. However, isotope records from this region reflect the combined effects of multiple climatic factors, and make climatic interpretations difficult. The authors use multi-proxy records, generated from the same sediment core from Qinghai Lake, to disentangle these multiple effects in isotope records and to infer EASM variability during the late Holocene. Records of leaf wax （C2s） δd, lake carbonate 5180 and the dunde ice core δ18O all indicate a millennial-scale depletion of mean isotopic values at -1500-1250 years before present. Compared with independent lake temperature and salinity records, the authors suggest that this depletion of long-term mean isotopic values must have resulted from changes in moisture sources in this region. In contrast, the authors attribute high-frequency （centennial timescale） C2s δd and ice core δ18O variability dominantly to a temperature effect. The multiproxy records provide a coherent picture in that many aspects of this regional climate （temperature, dryness, and moisture source） are strongly linked to the EASM variability.

敦巴顿橡树园中的连香树是北美最古老的连香树之一,在该花园建成之前就已存在。日本园艺大师藤元藏人受园方委托,检查并主导对这株古树的保护工作——“胡祖”(hoozue)是一种日本本土技术,通过对树木枝干进行一系列支撑,以使这株每况愈下的古老树木重新焕发青春。胡祖的建造和实施过程基于对树木的评估,包括对枝干结构的检查,以及对实施后未来几十年生长情况的预测。绳索、树皮保护裹布、钉子等材料的使用,以及木制胡祖本身的制作和安装都是依照日本本土知识和经验进行的,这些知识和经验也以图文的形式记录了下来。本文记述了这一保护项目的过程,展示了这一日本本土技术的重要意义。

Cremaster muscle thickening: the anatomic difference in men with testicular retraction due to hyperactive cremaster muscle reflex

引用

Asian Journal of Andrology 2023年第4期25卷 484-486页

作者： Parviz K Kavoussi Hayden T henderson Kayla Hudson Romtin Mehrabani-Farsi Graham Luke Machen Austin Fertility and Reproductive Medicine/Westlake IVF AustinTX 78746USA

The objective was to assess whether men suffering from testicular retraction secondary to hyperactive cremaster muscle reflex havean anatomic difference in the thickness of the cremaster muscle in comparison to men who do not have retraction. From March2021 to december 2021, 21 men underwent microsurgical subinguinal cremaster muscle release (MSCMR) on 33 spermatic cordunits, as 12 of them had bilateral surgery, at Surgicare of South Austin Ambulatory Surgery Center in Austin, TX, USA. duringthat same time frame, 36 men underwent subinguinal microsurgical varicocele repair on 41 spermatic cord units, as 5 werebilateral for infertility. The thickness of cremaster muscles was measured by the operating surgeon in men undergoing MSCMRand varicocele repair. Comparison was made between the cremaster muscle thickness in men with testicular retraction due toa hyperactive cremaster muscle reflex undergoing MSCMR and the cremaster muscle thickness in men undergoing varicocelerepair for infertility with no history of testicular retraction, which served as an anatomic control. The mean cremaster musclethickness in men who underwent MSCMR was significantly greater than those undergoing varicocele repair for infertility, witha mean cremaster muscle thickness of 3.9 (standard deviation [s.d.]: 1.2) mm vs 1.0 (s.d.: 0.4) mm, respectively. Men withtesticular retraction secondary to a hyperactive cremaster muscle reflex demonstrate thicker cremaster muscles than controls,those undergoing varicocele repair. An anatomic difference may be a beginning to understanding the pathology in men whostruggle with testicular retraction.
