The effect of the rotational speed and axial torque on the diagnostics of tapered rolling element bearing defects was investigated. The accelerometer was mounted on the bearing housing and connected to Sound and Vibration Analyzer (SVAN 958) and was used to measure the accelerations from the bearing housing. The data obtained from the bearing was processed to detect damage of the bearing using ...

We consider whether Sub-Saharan African (SSA) countries are mainly poor because they are governed worse than other countries, as suggested by recent studies on the supremacy of institutions. Our empirical results show that the supremacy of institutions does not hold. SSA countries appear to face specific development problems in addition to weak institutions. Given their geographic and economic ...

where Q is an indefinite quadratic form on Z, f(m,n) is a doubly periodic function on Z such that the sums of f(m,n)q over all vertical and all horizontal lines in Z vanish. Some of these series appeared as coefficients in univalued triple Massey products on elliptic curves computed via homological mirror symmetry in [3]. In particular, in this context the condition of vanishing of sums over ve...

A set of central themes, constituting both a method and an approach, demonstrated in the “Problems of...” conference series over the last quarter century, are extracted from the work of Gerard de Zeeuw. These themes are based in a consideration of and concern for improvement, and an attempt to reduce the frequently negative side-effects of attempts at improvement by creating “high quality obser...

Streptomyces graminofaciens BA14348, isolated from a soil sample, was found to produce new specific inhibitors of estrogen binding to its receptor. Five related substances, BE-14348A approximately E, were isolated, and their structures were determined by analyses of spectral properties. Of these substances, A was identical with the known flavanone, naringenin. On the other hand, B, C, D and E w...

the silica gel waste (sgw), after its collection from a local factory (kolkata, india) was modified with cationic surfactant and was utilized as an adsorbing media for the removal of 2,4- dichlorophenoxyacetic acid (2,4-d) from agricultural runoff of a tea garden. characterization of base adsorbent and modified adsorbent was carried out. the efficacy of the adsorbent was evaluated through both ...

the aim of this sutdy is to prepare histocompatability y(hy) antibody in female mouse at the first phase (current study), and to separate mouse embryos with regard to their sex, to be able to obtain offsprings of disired sex, by means of hy antibody, at the second phase. totally 421 balb/c inbred mice were used. antibodies were produced in females by intraperitonial injections of spleen and tes...

THEODORE J. WEIMAN On July 22, 2004, the House of Representatives passed the Marriage Protection Act of 2004, a bill that would strip the federal courts of jurisdiction over cases challenging the constitutionality of the 1996 Defense of Marriage Act. Two months later, the House passed a similar bill that would curtail federal court jurisdiction for challenges to the constitutionality of the Ple...
