Etiology and characteristics of congestive heart failure in blacks

The American Journal of Cardiology, 1996
In this study of 301 black patients with congestive heart failure (CHF), systemic hypertension is the most common cause of CHF and is the primary etiology of CHF in 61%. Left ventricular hypertrophy is highly prevalent and is seen in 63% of the patients who had an echocardiogram.

Failure and fatigue characteristics of adhesive athletic tape

Medicine & Science in Sports & Exercise, 2002
Athletic tape has been commonly reported to lose much of its structural support after 20 min of exercise. Although many studies have addressed the functional performance characteristics of athletic tape, its mechanical properties are poorly understood. This study examines the failure and fatigue properties of several commonly used athletic tapes.A Web ...

Failure to Thrive: A Controlled Study of Familial Characteristics

Journal of the American Academy of Child Psychiatry, 1983
The significance of ecological stress factors in the etiology of failure to thrive (FTT) was explored through structured interviews with mothers of 42 infants who were failing to thrive and 42 matched controls. Three factors distinguished the FTT families from the controls.

Ultrasonographic characteristics of early pregnancy failure in bitches

Theriogenology, 2006
Resorption 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.

Proliferation characteristics of erythroblasts in chronic renal failure

Blut, 1977
Proliferation 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

Statistical characteristics of serious network failures in Japan

Reliability Engineering & System Safety, 2014
Abstract Due to significant environmental changes in the telecommunications market, network failures affect socioeconomic activities more than ever before. However, the health of public networks at a national level has not been investigated in detail.

Acute renal failure in the elderly: particular characteristics

International Urology and Nephrology, 2006
Elderly individuals comprise the faster growing patient population group and acute renal failure (ARF) is quite common among them, although exact numbers are not known. We reviewed the literature with regards to the characteristics of ARF in elderly patients and describe some useful guidelines.

Hampered Production of Words as a Characteristic of School Failure

Journal of Learning Disabilities, 1988
The 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).

Control of Progressive Failure in Composite Laminates: Characteristic Failure Signatures

43rd AIAA/ASME/ASCE/AHS/ASC Structures, Structural Dynamics, and Materials Conference, 2002
Structural designs for composite laminated systems can be optimized for a fail-safe in-service performance by introducing the built-in cumulative-damageindicators for the progressive degradation of material properties. This design methodology is based on the concepts of the characteristic failure signature (CFS), the cumulative-damage-states and a load
