Platform independent Java application to support interaction between an instructor, teaching assistants and students in a traditional on-campus course is developed. The TSI (teacher-student interaction) application includes a specialized Web server, an ordinary Web server, a mailer and a simple database. The HTTP protocol is used for all communications. Both teachers and students employ Web bro...
BACKGROUND The heart was very sensitive to fluctuating thyroid hormone levels. To assess intra-left ventricular (LV) systolic asynchrony in patients with subclinical thyroid dysfunction. METHODS Fifty patients with subclinical hypothyroidism and 40 controls were included. A diagnosis of subclinical hypothyroidism was reached with increased TSH and normal free T4. All subjects were evaluated b...
AIMS We compared the effects of total thyroidectomy (TTx) and radioiodine (RAI) administration on the course of thyroid hormones and thyroid-stimulating immunoglobulins (TSI) in patients with Graves' disease. METHODS We retrospectively studied 80 patients initially treated with antithyroid drugs and requiring either RAI (8.3 ± 1.7 mCi of (131)I; n = 40) or TTx (n = 40) as second-line therapy....
Surface sediment and water samples were collected from Daihai Lake to study the biogeochemical characteristics of nitrogen and phosphorus, to estimate the loads of these nutrients, and to assess their effects on water quality. The contents and spatial distributions of total phosphorus (TP), total nitrogen (TN), and different nitrogen forms in sediments were analyzed. The results showed that con...
Para-water is an analogue of para-hydrogen, where the two proton spins are in a quantum state that is antisymmetric under permutation, also known as singlet state. The populations of the nuclear spin states in para-water are believed to have long lifetimes just like other Long-Lived States (LLSs). This hypothesis can be verified by measuring the relaxation of an excess or a deficiency of para-w...
It is believed that the global warming since the mid-20th century is primarily the result of the combustion of fossil fuel. The fact that the climate also changed in the past during periods of rather constant atmospheric greenhouse gas concentrations points to additional factors such as solar and volcanic forcing. The Sun is by far the most important source of energy for Earth and direct satell...
