Workloads heavy

Dynamic workload heavy manual handling, lifting (heavy or frequent, unexpected heavy, infrequent, torque), carrying, forward flexion of trunk, rotation of trunk, pushing/pulling... [Pg.1070]

Mean arterial pressure and cardiac output, an expression of the amount of blood that the heart pumps each minute, are the key Indicators of the normal functioning of the cardiovascular system. Mean arterial pressure is strictly controlled, but by changing the cardiac output, a person can adapt, e.g., to increased oxygen requirement due to increased workload. Blood flow in vital organs may vary for many reasons, but is usually due to decreased cardiac output. However, there can be very dramatic changes in blood pressure, e.g., blood pressure plummets during an anaphylactic allergic reaction. Also cytotoxic chemicals, such as heavy metals, may decrease the blood pressure. [Pg.297]

In 1985, with a young family and burdened by a heavy workload,... [Pg.163]

An estimate of the number of tests also is necessary for estimating computer core memory requirements if the data reduction workload is so heavy that computer data storage seems attractive. [Pg.429]

Because of the heavy workload placed upon the hydroxyl radical through such cleansing reactions in the atmosphere, some scientists are concerned that the atmospheric content of OH has diminished with increasing pollution, estimating the probable drop to be as much as 5-25% during the past three centuries since the start of the Industrial Revolution. Ironically, some of llte very pollulanls lltal are targets for reduction also are compounds from which the OH radical is produced and, as they are reduced, so will the concentration of OH be reduced. The fact that there is only one hydroxyl radical per trillion air molecules must not detract from its effectiveness as a scavenger. [Pg.13]

Given the above analysis and also the high cost of purchasing relatively small quantities of 5-aminoimidazole-4-carboxamide (XXIII, AIC), we in Chemical Development were given the backing to explore other possibilities and identify a safer, lower-cost route to Temozolomide that would avoid the hazards and preferably require conventional rather than specialist equipment. Another requirement, made necessary by the heavy workload in our New Jersey Chemical Development operation, was that we find an outside partner to carry out the process exploration work with us. [Pg.297]

The most creative application of the secondary cathode approach was described by Schelles and Van Grieken [24], who investigated its ability to determine the elemental constituents of polymeric materials. Mass spectrometric analysis has almost exclusively been directed at the determination of molecular weights and disparity characteristics secondary ion mass spectrometry (SIMS) [53,54] and matrix assisted laser desorption ionization (MALDI) [55,56] have carried the major share of the workload. Growing concerns over the fate of polymeric materials in the environment and the leaching of heavy metals into ground waters have necessitated the development of methods that permit the elemental analysis of bulk polymers. In addition, the use of polymers as immobilization media for waste remediation is also pressing these developments. [Pg.274]

Sue, who is 50 years old, works as an administrator in a busy office. She had to take the afternoon off again, in spite of the heavy workload in the office. She has been having severe headaches recently with visual disturbances these make her feel nauseous, and sometimes vomiting occurs. She was treating the headaches with painkillers such as paracetamol/acetaminophen for a while however, recently these drugs do not seem to help. Nobody in her family has suffered from any headaches like this, and she has never had any accident or injury to her head. She finally decides to see her family doctor. The doctor has now made a diagnosis and has prescribed sumatriptan. [Pg.21]

Typically, angina presents as pain, but sometimes patients experience a sensation of chest tightness or heaviness. These symptoms are made worse by heavy meals, emotional stress and by cold weather, since the latter causes peripheral vasoconstriction and increases the workload of the heart. [Pg.171]

Analytical unreliability may arise when new analysts or operators, samples, methods, or instruments are introduced. Loss of an analyst or operator and replacement by another is a common predictor of unreliability in analytical results, as is the shift of an analyst or operator to a new assignment or a temporary one for a vacation period or heavy workload. Thorough education and training can help prevent bad analyses that are caused by unfamiliarity with a process. [Pg.246]

Tissue In a mill manufacmring primarily facial grades from bisulfite pine and Kraft hardwood, the primary cause of foam is the wet strength resin used in production. The negative impact of foam is twofold. First, heavy foam would fill the basement, where the electrical room is located, creating the potential for a major fire. Second, entrained air in the stock would increase the workload on the fan pump, reducing machine efficiency and production. [Pg.55]

While working on the Manhattan Project, he traveled each day into New York City, at the same time carrying a full-time teaching schedule at Princeton — a crushing workload. He used to tell a story about those years with a bit of wry humor. After years of hard work, he had a store of light water enriched, as we remember, with about 25% of heavy water which he "loaned" to the government. At the end of the war, he was paid back in kind 100% heavy water diluted back to 25% heavy water. [Pg.41]

Typically, relatively high workloads can be tolerated for short periods of time. However, with longer exposure to heavy workloads and multiple exposures to shorter-duration heavy workloads, fatigue accumulates and worker capacity is diminished. [Pg.1161]

When this method is used, the fan can run normally, it does not affect the production and safety. But for the large depth, and a lot of roadway and complex ventilation system, you need to set up multiple measuring points, a heavy workload for measuring and computing is needed, and you will take a long time to measure the average density of the air. This method can not be directly concluded the natural wind pressure value of the ventilator in the multiple levels of multi loop ventilation system. [Pg.77]

Namely, if the quantity of gas emitted is beyond the limits of standard, sealing approach can be applied. But the method has heavy workload. [Pg.967]

In addition to the criteria listed above, significant improvements in hygiene and occupational safety conditions have also been achieved in the new lead and precious metals refining plants, with minimal fume emissions and the eradication of nearly all of the heavy manual workload characteristic of the old plant. A significant reduction in zinc consumption compared to the previous process has been observed. In addition, the recycle rate of dross material has been significantly reduced, and the overall predicted increase in plant capacity was achieved. These achievements along with the production ctqiadty increases were accomplished with virtually the same labour compliment as with the old plant. [Pg.200]

Improve maternal health Access to better medical facilities for maternal care, including medicine refrigeration, equipment sterilisation and operating theatres reduction in excessive workload and heavy manual labour improves health of pregnant women improved production and distribution of sex education literature and contraceptives access to distance medicine improved provision of cooked food, space heating and boiled water. [Pg.73]

Management of outsourcing was generally believed to be a critical factor in determining its safety impact. In particular, one individual noted that if managed properly, use of contractor services need not affect safety he observed that at his own airline, contractors were required to meet the same standards as airline personnel. Another individual remarked that at his airline, use of contractors in the maintenance field is quite limited. He pointed out that scheduled heavy maintenance is not contracted out at his airline, and that the airline has its own maintenance people wherever there is sufficient workload to justify that. Where the airline cannot afford to have its own maintenance people, and instead has contractors on call in case of problems. [Pg.54]

Determination of heavy metals and trace elements, e.g., lead, cadmium, copper, and zinc are best measured using atomic absorption. Electrothermal equipment has a wider application owing to its greater sensitivity. The workload, limited application of the tests, and the capital cost of equipment mean that spectrometers are located in larger laboratories. Inductively coupled plasma-mass spectrometry (ICP-MS) is used in some specialist centers, supplanting atomic absorption spectroscopy. [Pg.701]
