Nitrate and nitrite control of anaerobic respiratory gene expression is mediated by dual two-component regulatory systems. The sensors NarX and NarQ each communicate nitrate and nitrite availability to the response regulators NarL and NarP. In the presence of nitrate, the NarX protein acts as a positive regulator ("kinase") of both NarL and NarP activity. In the presence of nitrite, the NarX pr...

1) Smoking cessation 2) Replacement of the pharmacologic (pleasurable) sensations of nicotine in cigarette products with non-cigarette products that can be viewed as providing either medicinal nicotine or analogue chemicals with similar function 3) Reduction in toxic components of cigarette smoke immediately to levels that are suggested by current science as ‘‘acceptable’’ based on existing dos...

In this paper we propose a condition for rejecting the input word by an accepting splicing system which is defined by a finite set of forbidding words. More precisely, the input word is accepted as soon as a permitting word is obtained provided that no forbidding word has been obtained so far, otherwise it is rejected. Note that in the new variant of accepting splicing system the input word can...

there are hadiths whose understanding and accepting would become possible not merely through observing principles of communication and not for everybody, but rather for specific addresses who are endowed with specific degree of knowledge. such hadiths, which are narrated in shiite collections of hadiths in a variety of forms and by various chains of transmission, are entitled “difficult and com...

Islamic banks in Indonesia are currently experiencing quite rapid development. This happens because of regulatory changes that make it easier to establish and operate banks. In addition, is possible the Indonesian people, who mostly Muslim, have great potential for development banks, one which East Tanjung Jabung Regency area has strong traditions. study aims look at potential, preferences beha...

there are a number of requirements by which animals should be managed so that the best performance is achieved in a way acceptable to those responsible for the care of the animals and to the community generally. these requirements are the keys to good management and may be used to test the management of a poultry enterprise in relation to the standard of its management. these requirements are a...

BACKGROUND Elderly in several European countries are currently being vaccinated against influenza and pneumococcal disease, and various reasons have been put forward to expand these programs. To successfully immunize the older adult population, however, it is crucial for the target group to accept such interventions. This study aims to elucidate the motives of Dutch persons aged ≥ 50 years for ...

In this paper we consider the time and the crossing sequence complexities of onetape off-line Turing machines. We show that the running time of each nondeterministic machine accepting a nonregular language must grow at least as n logn, in the case all accepting computations are considered (accept measure). We also prove that the maximal length of the crossing sequences used in accepting computa...
