Metachronic Breast and Cerebellar Neoplasm in a Young Patient.

Several factors trigger the development of genetic mutations that are responsible for causing a neoplasm. Medulloblastoma is a malignant and invasive cerebellar neoplasm, that affects children and young adults. Mucinous carcinoma is a special type of breast cancer.

Differential effects of weather and natural enemies on coexisting aphid populations.

Study of mechanisms responsible for regulating populations of living organisms is essential for a better comprehension of the structure of biological communities and evolutionary forces in nature. Aphids (Hemiptera: Sternorrhyncha) comprise a large and economically important group of phytophagous insects distributed worldwide. Previous studies determined that density-dependent mechanisms play an important role in regulating their populations.

Applying systems engineering to implement an evidence-based intervention at a community health center.

Impressive results in patient care and cost reduction have increased the demand for systems-engineering methodologies in large health care systems. This Report from the Field describes the feasibility of applying systems-engineering techniques at a community health center currently lacking the dedicated expertise and resources to perform these activities.

Relation between index finger width and hand width anthropometric measures.

Measures of hand and finger anthropometry are very important for designing many hand held devices as well as understanding anthropometric effects on the operation of such devices. Many historical datasets have measured and recorded gross hand dimensions but do not often record the finer dimensions of the hand such as finger anthropometry. Knowing the size and mass of fingers across genders can be critical to the design and operation of hand held devices.

Relation between mouse button click duration and muscle contraction time.

Contraction and half relaxation times are important temporal measures of the physiological state of the muscle. We hypothesize that mouse button click durations may mirror muscle twitch contraction times (contraction time + half relaxation time). When comparing muscle twitch contraction times and mouse button-click durations between children, adult females and adult males only small differences in muscle twitch contraction times were observed across these groups whereas large differences in mouse button click durations were measured.
