Limit, short term

There has been limited short-term experience as anti-obesity agents with the SSRI citalopram [101,102], and with the serotonin-noradrenaline reuptake inhibitor venlafaxine [103], and no recommendations can be made re use of these agents solely as anti-obesity therapy in clinical practice. 

TSIIOSH REL-STEL (Recommended Exposure Limits - Short Term Exposure Limit) (NIOSH, 2005) is defined analogous to the ACGIH TLV-TWA.

Table 2-8 shows the mass equivalents for natural and depleted uranium for radiation levels that caused potential radiological effects in rats exposed once for 100 minutes to airborne 92.8% enriched uranium with an estimated specific activity of 51.6 pCi/g (Morris et al. 1989). These mass equivalent values for natural and depleted uranium for the minimal concentration of radioactivity that is expected to induce potential radiological effects are well above levels that would be expected to be inhaled or ingested. In addition, the mass equivalents for natural and depleted uranium for potential radiological effects are 3,600 and 76,500 times higher, respectively, than the occupational exposure limits (short-term exposure) recommended by the National Institute for Occupational Safety and Health (NIOSH 1997). Therefore, MRLs for uranium based on studies that used enriched uranium are inappropriate. 

The acute toxicity of 1,1,2,2-tetrachloroethane in experimental animals is slight to moderate. This material is a skin, eye, and respiratory irritant. The oral LD50 has been reported from 250 to 1000 mg kg in the rat. Exposure to 1000 ppm for 4-6 h caused death in rats. Dermal and ocular irritations were reported in rabbits exposed to 580 ppm of 1,1,2,2-tetrachloroethane. There are limited short-term data available however, single low-level inhalation exposure effects have been reported to include hepatic... 

Recycling of nutrients further complicates the nature of limitation. Short term depletion of soil nutrient concentration by vegetation can eventually feed back, through litter production and mineralization processes.

Research and anecdotal evidence indicate that a number of factors can impair human performance. While working in complex surroundings, humans can easily experience a limited short-term memory. Running late or being in a hurry can impact task performance. Some individuals find it very difficult to multitask. 

As shown in Figure 11.1, any production framework actually defines a production process push-pull boundary across the order fulfillment cycle. On the left of the boundary, we have the production resources made available by the push-based planning processes. Customer orders arise, on the right of the boundary, to compete for these limited short-term production resources. The ATP system executes at the interface of the push-driven flow and pull-based flow systems. It plays a critical role in making best use of available resources, including raw materials, work-in-process, finished goods, and even production and distribution capacities, to commit customers order requests over a period of time across a supply chain. By doing so, it coordinates activities across the push-pull boundary of a supply chain. 

Maximum use concentration (MUC) means the maximum atmospheric concentration of a hazardous substance from which an employee can be expected to be protected when wearing a respirator, and is determined by the assigned protection factor of the respirator or class of respirators and the exposure limit of the hazardous substance. The MUC can be determined mathematically by multiplying the assigned protection factor specified for a respirator by the required QSHA permissible exposure limit, short-term exposure limit, or ceiling limit. When no QSHA exposure limit is available for a hazardous substance, an employer must determine an MUC on the basis of relevant available information and informed professional judgement.

IDLH (Immediately Dangerous to Life and Health, National Institute cf Occupational Safety and Health) (NIOSH, 2010) represents the maximum concentration from which one could escape within SOmin without any escape-impairing symptoms, or any irreversible hmlth fffects. The IDLHfor phosgene is based on acute inhalation toxicity data in humans (Diller, 1978). NIOSH REL-STEL (Recommended Exposure Limits—Short Term Exposure Limit) (NIOSH, 2010) is dffined analogous to the ACGIH TLV-TWA.
