Water is one of the prime necessities of life. We can hardly live for a few days without water. In a man's body, 70-80% is water. Cell, blood, and bones contain 90%, 75%, and 22% water, respectively. ...The general survey reveals that the total surface area of earth is 51 crore km(2) out of which 36.1 crore km(2) is covered sea. In addition to this, we get water from rivers, lakes, tanks, and now on hills. In spite of such abundance, there is a shortage of soft water in the world. Physicochemical parameter of any water body plays a very important role in maintaining the fragile ecosystem that maintains various life forms. Present research paper deals with various water quality parameter, chlorides, dissolved oxygen, total iron, nitrate, water temperature, pH, total phosphorous, fecal coli form bacteria, and adverse effect of these parameters on human being.
According to the Newtonian formula for a simple pendulum, the period of a pendulum is inversely proportional to the square root of g, the gravitational field strength. Einstein's theory of general ...relativity leads to the result that time slows down where gravity is intense. The two claims look contradictory and can muddle student and teacher alike. There is, however, no real paradox. This article, which aims to clarify the conceptual issues, identifies two sources of confusion. One is a failure to distinguish a pendulum from a pendulum clock. The other is a failure to distinguish between two distinct gravitational fields.
To analyze population pharmacokinetics of Propofol in Indian patients after single bolus dose of Propofol using WINNONLIN program.
Population pharmacokinetics of Propofol was investigated in Indian ...subjects in 26 elective surgical patients (14 males and 12 females) following single bolus dose of 2 mg/kg propofol. A total of 364 samples were estimated by High Performance Liquid Chromatography and pharmacokinetic parameters were derived using WINNONLIN (5.2). The effect of demographic characters of the study population on pharmacokinetic parameters was investigated.
Three-compartment model was used to describe the pharmacokinetic data of Propofol in Indian subjects. Initial volume of distribution (V1) clearance (Cl) and steady state volume of distribution (Vd(ss)) was 13.5 ± 3.3 l, 1.08 ± 0.42 l/min, and 77.69 ± 48.0 l, respectively. Body weight best described the volume of central compartment (V1) as well as elimination clearance (P<0.01).
Pharmacokinetics of Propofol in young healthy Indian subjects show lower volume of distribution and clearance as compared with most of the western data. Body weight best describes the V1, Vd(ss), and Clearance in this group.
Propofol is a potent intravenous hypnotic agent, which is widely used for induction and maintenance of anesthesia and for sedation in the intensive care unit. It has a quick onset of action with a ...dose related hypnotic effect The onset of hypnosis is rapid, i.e. in one arm brain circulation time when it is used in doses 2.0-2.5 mg/kg, with a peak effect seen at 90 to 100 seconds, duration of hypnosis is dose dependent (5-10 minutes with 2.5mg/kg). Recovery is rapid even after prolonged use as the required decrease in blood concentration for awakening after anesthesia is less than 50%. These properties make propofol an excellent induction and maintenance agent. As a result of these properties, propofol is extensively used in anesthesia as a sedative agent in intensive care units, radiology and gastroenterology procedures. It is also considered as one of the anesthetic drugs of choice for out-patient surgeries Propofol decreases cerebral oxygen consumption and reduces intracranial pressure making it an excellent anesthetic agent for neuro-surgeries. Propofol is also preferred for cardiac surgeries as it is an important component of fast track cardiac anesthesia. It is a potent anti-convulsant, antioxidant and a bronchodilator. As a consequence of these properties, propofol is being increasingly used in the management of status epilepticus and status asthmaticus.
