Calculation of the Failure Characteristics
1993In the description of the equivalent reliability margins \(Z \in {\dot Z_{eqv}}\), discussed in 7.2.2, the ordered n -tuplet of non-random variables \(({x_{1,}}{x_{2,}}\ldots {x_n})\) appeared. Let us now assume that all elementary variables entering the expression for Z are independent random variables, \({\xi _1},{\xi _2}, \ldots,{\xi _n}\), which ...

Ultrasonographic characteristics of early pregnancy failure in bitches
Theriogenology, 2006Resorption of conceptuses was identified in 6 of 20 bitches examined daily from 15 to 35 d after the estimated pre-ovulatory LH surge. One or more conceptuses were resorbed in each bitch but there was continuation of the remaining pregnancy to term.

Failure Characteristics of Various Arthroscopically Tied Knots
Clinical Orthopaedics and Related Research, 2003The current study evaluated multiple arthroscopic knot configurations and compared their properties with open, hand-tied square knots. This is an experimental study done on a material testing system. Number 2 Ethibond Extra and Number 1 Polydioxanone sutures were used.

Characteristics of Crack Failure
1968Part I describes plane strain yielding, stresses and fracture about notches and cracks in terms of flow and fracture stresses and crack tip radii and, using generally appropriate dimensionless variables, it presents a graph of sub-surface fracture loci and a Table (I) from which notch and crack failure can be computed.

Psychological characteristics of males with secondary erectile failure
Archives of Sexual Behavior, 1981This study was designed to obtain objective data on the personality profiles of two groups of males with a primary complaint of erectile failure and compare them to a group of psychiatric patients unselected for sexual dysfunction and to a sexually "normal" control group.

Characteristics of the failure of tool materials
Metal Science and Heat Treatment, 1994Tool materials for metal cutting tools, with hardness exceeding 62 HRC as a rule, are destroyed, in distinction to most structural steels and alloys, by brittle failure without any noticeable macroscopic deformation. The article examines the characteristics of such failure.

Virological and immunological characteristics of HIV treatment failure
AIDS, 2000Resistance to antiretroviral treatment is prevalent. There is limited knowledge of the determinants of disease evolution in subjects infected with multidrug-resistant HIV (MDR-HIV).Infectivity, replication, chemokine receptor usage, and env, gag, protease and reverse transcriptase sequence analysis was performed for MDR-HIV isolates from 14 HIV ...

The prevalence and characteristics of pruritus in patients with heart failure
British Journal of Dermatology, 2015Pruritus (itching) can be a distressing symptom, and previous research suggests that it is common in patients with chronic heart failure (CHF).The primary aim was to examine the prevalence of itching in patients with CHF and to compare this first to that among patients with coronary artery disease (CAD) and second to that of a normal Swedish population.

Hampered Production of Words as a Characteristic of School Failure
Journal of Learning Disabilities, 1988The present study demonstrated that children with learning problems are characterized not by a restricted vocabulary as such (i.e., the variance common to both receptive and productive vocabulary measures), but by a hampered production of words (i.e., the variance common to both speed-of-naming and productive vocabulary measures).

Proliferation characteristics of erythroblasts in chronic renal failure
Blut, 1977Proliferation of bone marrow erythroblasts in patients with chronic renal disease was studied by combined application of cytophotometric measurement of the DNA content and 3H-TdR labeling in vitro. A striking decrease of 3H-TdR labeling was found in most of the cases. The proportion of diploid (G0 + G1) as well as of tetraploid unlabeled cells (G2) was
