What's the difference between causal and experimentation?

Causal


Definition:

  • (a.) Relating to a cause or causes; inplying or containing a cause or causes; expressing a cause; causative.
  • (n.) A causal word or form of speech.

Example Sentences:

  • (6) The most important causal factor, well illustrated by pressure studies, was the presence of a dynamic or static deformity leading to local areas of peak pressure on insensitive skin.
  • (7) The results support Kuiper and colleagues' distinction between concomitant and vulnerability schemas, and help to clarify differences between cognitions that are symptoms or correlates of depression and those that may play a causal role under certain conditions.
  • (8) This inhibition was correlated with the enhanced Ado toxicity, suggesting inhibition of methylation as a possible causal factor for the great increase in Ado sensitivity.
  • (9) It is felt that the use of quinidine was causally related to the development of nephrotic syndrome in this patient.
  • (10) Epidemiological criteria for a causal association between snoring and vascular disease have not been satisfied.
  • (11) Although the pathophysiology of the pancreatic injury is obscure, the lack of other etiological factors and temporal association of the pancreatitis with acetaminophen-induced hepatic and renal toxicity suggest a causal relationship.
  • (12) Twenty-three unique causal pathways to diabetic limb amputation were identified.
  • (13) With tetrachlorodecaoxide (TCDO), a causal therapeutic concept for the topical treatment of infected hypoxic wounds with chronic disturbance of wound healing has been introduced for the first time.
  • (14) A recording which implies mtabolic disorder should prompt the immediate search for the causal disturbance.
  • (15) It is not possible to say whether the changes in PRA and function are causally related or whether changes in plasma sodium alone account for the observed changes in PRA.
  • (16) The human mutant proteins were isolated by immunoaffinity and shown to have altered enzymatic properties demonstrating the causality of these two allelic mutations for Gaucher disease.
  • (17) Using this approach, a potential causal linkage between early functional patterns and late structural abnormalities was examined in glomeruli of two established rat models of glomerular sclerosis.
  • (18) Nonexperimental and experimental studies related to handwashing were reviewed and evidence for a causal association evaluated.
  • (19) Mitochondria may also be causally related to the cytotoxic or antitumor activities, in that DPPE may be concentrated in cells via the presence of the inner mitochondrial membrane potential.
  • (20) Whether these two effects are causally related awaits future study.

Experimentation


Definition:

  • (n.) The act of experimenting; practice by experiment.

Example Sentences:

  • (1) Similar experimental manipulation has yielded in vitro lines established from avian B-cell lymphomas expressing elevated levels of c-myc or v-rel.
  • (2) The distribution and configuration of the experimental ruptures were similar to those usually noted as complications of human myocardial infarction.
  • (3) The predicted non-Lorentzian line shapes and widths were found to be in good agreement with experimental results, indicating that the local orientational order (called "packing" by many workers) in the bilayers of small vesicles and in multilamellar membranes is substantially the same.
  • (4) Clinical signs of disease developed as early as 15 days after transition to the experimental diets and included impaired vision, decreased response to external stimuli, and abnormal gait.
  • (5) The various evocational changes appear to form sets of interconnected systems and this complex network seems to embody some plasticity since it has been possible to suppress experimentally some of the most universal evocational events or alter their temporal order without impairing evocation itself.
  • (6) Single-case experimental designs are presented and discussed from several points of view: Historical antecedents, assessment of the dependent variable, internal and external validity and pre-experimental vs experimental single-case designs.
  • (7) Parents of subjects at the experimental school were visited at home by a community health worker who provided individualized information on dental services and preventive strategies.
  • (8) In each study, all subjects underwent four replications (over two days) of one of the six permutations of the three experimental conditions; each condition lasted 5 min.
  • (9) Content of cyclic nucleoside monophosphates was decreased in all the eye tissues in experimental toxico-allergic uveitis as well as penetration of cAMP into the fluid of anterior chamber of the eye.
  • (10) The performance characteristics of the CCD are well documented and understood, having been quantified by many experimenters, especially in the physical sciences.
  • (11) Because of the dearth of epidemiological clues as to causation, studies with experimental animal models assume greater importance.
  • (12) A beta-adrenergic receptor cDNA cloned into a eukaryotic expression vector reliably induces high levels of beta-adrenergic receptor expression in 2-12% of COS cell colonies transfected with this plasmid after experimental conditions are optimized.
  • (13) Neither Brucella organisms, nor increased numbers of neutrophils could be found in semen samples collected from the experimental animals.
  • (14) An experimental Anaplasma marginale infection was induced in a splenectomized mule deer (Odocoileus hemionus hemionus) which persisted subclinically at least 376 days as detected by subinoculation into susceptible cattle.
  • (15) Reasonably good agreement is seen between theoretical apparent rate-vesicle concentration relationships and those measured experimentally.
  • (16) This value is about 30 times higher than the association constant for guanine-cytosine base pair formation under the same experimental conditions.
  • (17) This experimental system allows separation of three B lymphocyte developmental stages: early differentiation in vitro, progression to IgM secretion in vivo, and late differentiation dependent upon mature T lymphocytes in vivo.
  • (18) An experimental autoimmune model of nerve growth factor (NGF) deprivation has been used to assess the role of NGF in the development of various cell types in the nervous system.
