Comparison of the effects of delayed auditory feedback on speech and key tapping     

CHASE RA  HARVEY S  STANDFAST S  RAPIN I  SUTTON S 《Science (New York, N.Y.)》1959,129(3353):903-904

Delaying the return of a speaker's vocal output to his ears (the auditory feedback) radically changes his speech (1). The present report concerns the effect of delayed auditory feedback on simple key-tapping tasks. Evidence is presented which indicates that changes in speech and key tapping under delayed auditory feedback are analogous.  相似文献

Histological and immunohistochemical investigations of ovarian interstitial glands during non‐breeding season in camels (Camelus dromedarius)          下载免费PDF全文

MM Awad  RH Mohamed  YA Amin  HA Hussein 《Reproduction in domestic animals》2018,53(4):872-879

The aim of this was to investigate the histology and immunohistochemistry of interstitial glands during non‐breeding season in camel ovaries. A total of 21 mature, non‐pregnant and apparently healthy camels aged between 8 and 12 years were slaughtered. The ovaries were removed within 15 min, cleaned from adipose tissue, weighted and examined grossly. The histological preparation was made, and then, the blocks were cut at 3–5 microns thickness and stained by H&E for histological examinations. Moreover, some sections were stained with Sudan Black for lipid detection. Immunohistochemical analysis of paraffin‐embedded ovarian tissues was performed to detect the localization of S‐100, vimentin, progesterone receptors (PR) and oestrogen receptors (ER). Immunoreactive signals were detected using UltraVision Detection System. The results revealed that the interstitial glands were located in the cortical region and they were arranged in various arrangements either single, in couple or in groups rich in lipid droplet. All interstitial gland arrangements were enclosed by connective tissue capsules containing fibroblasts and collagenous fibres separated them from the surrounding ovarian structures. Both interstitial glands and their surrounding CT were penetrated by several blood vessels. There was a strong immunoreactive signal for S‐100 in the nuclei of interstitial cells, and no signals were detected either in cells of the interstitial glands or their connective tissue with PR. We could conclude that the interstitial gland is distinct in ovary of camel and further studies are needed to elucidate its rule in steroid synthesis.  相似文献   

Materials with negative compressibilities in one or more dimensions     

RH Baughman  S Stafstrom  C Cui  SO Dantas 《Science (New York, N.Y.)》1998,279(5356):1522-1524

Rare crystal phases that expand in one or more dimensions when hydrostatically compressed are identified and shown to have negative Poisson's ratios. Some of these crystals (i) decrease volume and expand in two dimensions when stretched in a particular direction and (ii) increase surface area when hydrostatically compressed. Possible mechanisms for achieving such negative linear and area compressibilities are described for single crystals and composites, and sensor applications are proposed. Materials with these properties may be used to fabricate porous solids that either expand in all directions when hydrostatically compressed with a penetrating fluid or behave as if they are incompressible.  相似文献

Nervous disorders in dogs associated with levamisole therapy     

R. H. SUTTON  R. B. ATWELL† 《The Journal of small animal practice》1982,23(7):391-397

The onset of nervous disorders associated with levamisole hydrochloride therapy is described in five dogs. Distemper and granulomatous encephalomyelitis were diagnosed in four cases. Possible stimulation of the cellular immune response by levamisole, with resultant secondary tissue damage, was believed to be associated with the time of onset and the severity of these disorders. The neuronal degeneration in the fifth case was not consistent with an inflammatory disorder. The possible role of levamisole in this case is unknown.  相似文献   

RE-SORPTION OF SOIL PHOSPHATE DURING FRACTIONATION     

N. RAJENDRAN  C. D. SUTTON 《European Journal of Soil Science》1970,21(1):199-202

Studies with ³²P on six soils showed that considerable re-sorption of phosphate occurred during the Chang and Jackson fractionation procedure. This re-sorption resulted in an underestimate of the NH₄Cl-extractable phosphate and an overestimate of‘occluded’ phosphate, with less consistent but significant changes in the other fractions. The corrections necessary to allow for re-sorption varied between soils.  相似文献   

Integrated optoelectronic devices based on conjugated polymers   总被引：1，自引：0，他引：1  

H Sirringhaus  N Tessler  RH Friend 《Science (New York, N.Y.)》1998,280(5370):1741-1744

An all-polymer semiconductor integrated device is demonstrated with a high-mobility conjugated polymer field-effect transistor (FET) driving a polymer light-emitting diode (LED) of similar size. The FET uses regioregular poly(hexylthiophene). Its performance approaches that of inorganic amorphous silicon FETs, with field-effect mobilities of 0.05 to 0.1 square centimeters per volt second and ON-OFF current ratios of >10(6). The high mobility is attributed to the formation of extended polaron states as a result of local self-organization, in contrast to the variable-range hopping of self-localized polarons found in more disordered polymers. The FET-LED device represents a step toward all-polymer optoelectronic integrated circuits such as active-matrix polymer LED displays.  相似文献
