Achievements obstacles

In order to achieve a high level of product safety it is well known that good work practices in the bench are necessary, and having a clean environment and proper work clothing are of vital importance. Knowledge about the interaction between air movements and the dispersion of contaminants plays an important role. Wake regions and vortex streets can easily be formed behind obstacles. 

Literature provides the basis for a user to objectively determine the maximum flame speed that will be achieved with a particular combination of confinement, obstacles, fuel reactivity, and ignition source. ... 

What the talk did not address was whether and how aims b) and c) might be achieved. It is the purpose of this paper to remedy this omission. It will, first, analyse recent developments affecting energy in the political and economic fields. That is to be followed by considering the obstacles to the achievement of greater public support and a discussion whether these can be overcome. Lastly, we draw some conclusions... 

Potential obstacles for the large-scale application of phytoremediation technologies, however, include the time required for remediation, the pollutant levels tolerated by the plants used, the disposal of the contaminated plants, and the fact that only the bioavailable fraction of the contaminants will be treated. This means that phytoremediation does not achieve 100% removal or reduction of the contaminants From the ecological, toxicological, and medical (health) points of view, the... 

Researchers have many obstacles to overcome in the quest to make macroelectronics the next big thing. The keys to achieving the desired levels of functionality for a wide range of large-area electronic functions are advances in materials and processes and device structures that can get cost down to pennies (rather than dollars) per square centimeter.Tools and process methods... 

Parenteral administration is not perceived as a problem in the context of drugs which are administered infrequently, or as a once-off dose to a patient. However, in the case of products administered frequently/daily (e.g. insulin to diabetics), non-parenteral delivery routes would be preferred. Such routes would be more convenient, less invasive, less painful and generally would achieve better patient compliance. Alternative potential delivery routes include oral, nasal, transmucosal, transdermal or pulmonary routes. Although such routes have proven possible in the context of many drugs, routine administration of biopharmaceuticals by such means has proven to be technically challenging. Obstacles encountered include their high molecular mass, their susceptibility to enzymatic inactivation and their potential to aggregate. 

The lack of financial profit of the production of orphan drug production is the main obstacle in achievement of the protection task. NBC orphan drugs (NBC-OD) are necessary in large amount, only in critical situations (war, natural or technological disaster, terrorist attack etc ). Practically all NBC-OD, with very few exceptions, like anthrax vaccine, have no civil use, as drugs. 

However, there still remain limitations to C-H functionalization chemistry in order to achieve the goal of high turnover, selective, clean catalysis employing mild conditions. It is hoped that these issues will be addressed and at least some of the obstacles will be overcome in the next decade. 

There has much analysis in the petroleum industry as what is the prudent spacing table to use in the layout of an onshore facility. Attempts have even been made to compare the spacing tables used by individuals companies. This would provide a consolidated table the entire industry could apply. Although such an idea is admirable, there are several obstacles in achieving such a goal.
