Present study attempts to understand the potential of multispectral ASTER (Advanced space borne thermal emission and reflection radiometer) data for spatial mapping of kimberlite. Kimberlite is an economic rock known for hosting diamond. Kimberlite also has petrogenetic importance for giving us clue on the composition of lower part of the mantle. Kimberlites often contain serpentine, carbonate minerals;which have their diagnostic spectral signatures in short wave infrared (SWIR) domain. In the present study, attempt is made to delineate kimberlite from adjacent granite-granodiorite gneiss based on processing of the ASTER data as ASTER’s spectral channels can detect some of the diagnostic absorption features of kimberlites. But it has been observed that the kimberlites are difficult to be delineated by processing the ASTER data using correlative information of both sub-pixel and per-pixel mapping. Moreover, smaller spatial size of kimberlites with respect to pixel size of ASTER SWIR channels further obscures the spectral feature of kimberlite. Therefore, an attempt is also made to understand how intra pixel spectral mixing of kimberlite and granite granodiorite-gneiss modifies the diagnostic spectral feature of kimberlite. It is observed that spectral feature of kimberlites would be obscured when it is has very small spatial size (one-tenth of pixel) with respect to pixel size. Moreover, calcrete developed in the adjacent soil has identical absorption feature similar to the spectral features of kimberlites imprinted in the respective ASTER convolved spectral profiles. This also has resulted false-positives in ASTER image when we use spectral feature as a tool for spatial mapping of kimberlite. Therefore hyperspectral data with high spatial and spectral resolution is required for targeting kimberlites instead of using broad band spectral feature of kimberlites.

Primary pleural lymphoma is a rare entity that has been described in association with human immunodeficiency virus （HIV） infection or pyothorax. This paper reports on a 27 year old man with no history of HIV infection or pyothorax who presented with progressive dyspnea and heaviness of *** radiography revealed complete opacification of the left hemithorax, and contrast enhanced computed tomography showed large left pleural effusion and homogeneous, extensive thickening of the parietal pleura. CT guided biopsy of thickened pleura is suggestive of non-Hodgkin＇s lymphoma-T cell lymphoblastic variety. Physicians should be aware of this rare location of primary pleural lymphoma manifested by thickening of the pleura.

喷煤管是水泥回转窑的关键承力部位,长期承受高温熟料粉尘和气流的剧烈冲刷,需具备优异的高温力学性能。本工作分别以新型SioxX-Zero和传统铝酸钙水泥为结合剂,采用板状刚玉、α-Al_(2)O_(3)微粉和碳化硅等为主要原料,分别在1100℃和1400℃热处理3 h,制备了喷煤管用无水泥和低水泥结合Al_(2)O_(3)-SiC质浇注料,并研究了新型SioxX-Zero结合剂对浇注料显微结构、常规物理性能和高温力学性能的影响。结果表明:与传统铝酸钙水泥相比,SioxX-Zero能有效提高浇注料流动值和延缓流动值衰减,改善其施工性能。同时,含SioxX-Zero的Al_(2)O_(3)-SiC质浇注料中原位生成了数量较多、尺寸较大的针状莫来石,大幅改善了材料的常温抗折/耐压强度、高温抗折强度和高温耐磨性能。

The influence of a growth factor supplemented serum-free system on the development, gene expression, and cryotolerance of in vitro pro- duced bovine embryos was investigated. To assess the embryo development and gene ex- pression in blastocysts, abattoir-derived oo- cytes (obtained from 3 - 10 or <3 mm follicles) were matured and fertilized in serum-free media and cultured in synthetic oviductal fluid sup- plemented with fetal bovine serum (FBS, 4%), epidermal growth factor (EGF, 10 ng/mL), insulin like growth factor-1 (IGF-1, 100 ng/mL), stem cell factor (SCF, 50 ng/mL) or combinations of the growth factors. Expressions of selected gene transcripts were relatively quantified in the d 8 blastocysts. To assess the cryotolerance, d 4 morulae (derived from 3 - 10 mm follicles and cultured with the supplementation of FBS or combinations of the growth factors) were vitri- fied, thawed and cultured (with respective sup- plementations). Total cell number and DNA frag- mentation in blastocysts derived from the vitri- fied morulae were assessed through TUNEL assay. The rate (%) of cleavage, blastocyst and expanded/hatched blastocyst did not differ among the culture medium supplementations within the follicle size of 3 - 10 mm (range 65.1 ± 4.3 - 75.4 ± 3.9;22.4 ± 3.9 - 36.4 ± 3.6;and 11.2 ± 2.9 - 23.3 ± 3.2, respectively) or <3 mm (range 59.3 ± 4.2 - 74.5 ± 3.7;15.0 ± 3.5 - 28.7 ± 4.5;and 9.3 ± 2.8 - 17.3 ± 2.7, respectively). Nevertheless, significantly lower (P < 0.05) cleavage and blastocyst rates with FBS and lower blastocyst rate with SCF supplementations were observed for the oocytes derived from <3 compared to 3 - 10 mm follicles. The expression patterns of BCL-2, BAX, HSP1A1, GJA1 and BIRC5 tran- scripts varied significantly (P < 0.05) in all cases, except for BIRC5 in the blastocysts derived from 3 - 10 mm follicles. Following thaw and culture, the development (%) of vitrified morulae into expanded/hatched blastocysts was lower (P < 0.01) with the supplementation of
