4482   Comparative Investigation of 200KtsS-2 Condenser with Smooth and Knurled Tubes. Comparative Investigation of 200KtsS-2 Condenser with Smooth and Knurled Tubes.    1982 Results of investigations of the condenser manufactured by the Leningrad Metal Works are presented. The cooling surface of two condenser versions consisted of smooth and knurled tubes. It is shown that the heat transfer coefficient of the condenser is considerably higher when smooth tubes are replaced by the knurled ones. Comparative investigations of the material of knurled and smooth tubes and of the nature of deposits in them following opeation are summed up. 查看全文

4485   Near infrared measurement of cotton fiber micronaire, maturity and fineness - a comparative investigation Near infrared measurement of cotton fiber micronaire, maturity and fineness - a comparative investigation    2010 A key cotton fiber quality property is micronaire, which acts as an indicator of the fiber's maturity and fineness. Previous studies have demonstrated the ability of Near Infrared (NIR) instrumentation to measure these cotton properties with varying degrees of success, but these studies did not provide conclusions on the capabilities of NIR spectroscopy as a general technique for these analyses. Recent advances in NIR technology could result in improved measurements of these cotton properties. A... 查看全文

4486   Comparative investigation of N-heptane droplet ignition in high temperature convective environments Comparative investigation of N-heptane droplet ignition in high temperature convective environments    2008 A 2-D numerical model was proposed to investigate the ignition of liquid fuel droplets in convective environments at high temperature. This model employed a skeletal mechanism consisting of 34 reactive species and 56 elementary reactions, rather than one-step overall reaction as in normal 2-D droplet ignition models, because the skeletal mechanism for n-heptane reproduces ignition delay times at various temperatures and pressures reasonably well. In present investigation an emphasis was addresse... 查看全文

4487   Reference load for a conventional 138K CBM LNG carrier in a comparative approach Reference load for a conventional 138K CBM LNG carrier in a comparative approach    2009 Still limited to knowledge about the actual phenomena so far, the comparative method has been used to assess the design load and the strength of cargo containment system for target ship designs. In the comparative approach, the sloshing load and strength of a conventional sized LNG carrier are compared with the load and strength for target LNG vessels. A 138,000 m3 LNG carrier with 4 cargo tanks is used as a reference vessel in the comparative approach according to the market practice. Recently,... 查看全文

4489   Comparative investigation of replication techniques used for the study of (S + Au)-sensitized AgBr microcrystals Comparative investigation of replication techniques used for the study of (S + Au)-sensitized AgBr microcrystals    1996 A full understanding of the chemical sensitization of silver halide microcrystals with nanoscale silver/gold-sulfide clusters requires knowledge of both their nature and distribution on the microcrystal surface. Because direct electron microscopy studies of sensitized silver halide microcrystals are almost impossible, due to the electron-induced release of photolytic silver, one must resort to reliable preparation techniques such as carbon replication or gelatin encapsulation. In the present stu... 查看全文

4490   Resonance Raman and theoretical investigation of the photodissociation dynamics of benzamide in S3 state Resonance Raman and theoretical investigation of the photodissociation dynamics of benzamide in S3 state    2008 Resonance Raman spectra were obtained for benzamide in methanol and acetonitrile solutions with excitation wavelengths in resonance with the S 3 state. These spectra indicate that the Franck-Condon region photodissociation dynamics have multidimensional character with the motions mainly along the benzene ring C=C stretch ν9, the Ph-CO-NH 2 and ring benzene stretch ν14, the CCH in plane bend ν17, the Ph-CO-NH2 stretch and NH2 rock ν19, the ring trigonal bend ν23, and the ring defor... 查看全文

4492   Investigation of the MS-Al2S3 systems (M = Ca, Sr, Ba) and luminescence properties of europium-doped thioaluminates Investigation of the MS-Al2S3 systems (M = Ca, Sr, Ba) and luminescence properties of europium-doped thioaluminates    1992 Solid state-investigation of the MS-Al2S3 systems (M = alkaline earth) shows the existence of the following thioaluminates: CaAl2S4, SrAl2S4, Sr2Al2S5, BaAl4S7, BaAl2S4, Ba2Al2S5, Ba4Al2S7 and Ba5Al2S8. All are isostructural with homologous thiogallates. When substituted for M, divalent europium shows an emission in all host lattices.

4493   Comparative thermal cyclic testing and strength investigation of different Be/Cu joints Comparative thermal cyclic testing and strength investigation of different Be/Cu joints    1998 One of the main problems for ITER divertor target technology is to provide a reliable joint between Be as armour material and copper alloy heat-sink structure. Such joints are to satisfy numerous requirements. In particular these joints should successfully withstand cyclic hear fluxes and should have good properties after neutron irradiation. To study such a complex problem, several investigation stages were planned in Russia. This paper presents the results of comparative thermal cyclic testing... 查看全文

4502   Temporal Bone Carcinoma: Contemporary Perspectives in the Skull Base Surgical Era† Temporal Bone Carcinoma: Contemporary Perspectives in the Skull Base Surgical Era† MP Santos, SD Gutierrez-Nibeyro, AA Stewart, RM Hyde and DH Rodgerson    2009 Historically, malignant tumors that arose within the temporal bone or that intimately juxtaposed the petrous ridge portended an ominous prognosis. Perusal of the surgical literature from 1950 to 1975 strongly supports the impression that despite heroic surgical efforts many of these patients sustained significant morbidity and a high mortality rate. 查看全文
