Rather than obsessiveness being an odd quality possessed by eccentrics and geniuses, perhaps you could say it is a fairly ubiquitous response to the difficulties of being human – the key difference is whether it propels you to over-consume, to kill people who don't agree with you, or to shred your fingers clambering up rocks.
Vague complaints, like aches and pains and difficulty sleeping are ubiquitous.
However, perhaps hoping to lower the barrier of entry for users, and with the advent of more ubiquitous Internet connections, or the difficulty in persuading the majors to jump on-board with such an innovative and, perhaps controversial model, We7 gradually shifted to ad-supported streaming via a web browser.
However, high cost, long time consumption, extensive effort, and in some cases irrevocability are the main challenges and difficulties for developing ubiquitous systems.
In regard to the ubiquitous system itself, some practical difficulties were expressed by users.
Another recently described baculovirus immediate-early promoter, ie1, also exhibits limited activity in the larvae (Masumoto et al. 2012), demonstrating the difficulty of identifying a bona fide ubiquitous promoter.
Reduced-representation approaches, such as methylation filtration (MF) and Cot-based cloning and sequencing, have been developed to alleviate some of the difficulties presented by the presence of ubiquitous repetitive DNA [ 23- 27].
However, the biological consequences of these ubiquitous lesions are not fully understood due to the difficulty of generating DNA substrates containing structurally defined, site-specific DPCs.
By treating the endogenous retroviruses as inheritable loci, we have brought the formidable knowledge of human genetics to bear on their role in disease, and avoided the difficulties of establishing the causality of a ubiquitous agent by conventional means.
Most of these difficulties are of two types: those that are ubiquitous among students in all areas of biology and those that stem from an inadequate understanding of FCs from developmental, cell, and molecular biology.
b) Exposure assessment is a particular difficulty of EMF epidemiology, in several respects: i) The exposure is imperceptible, ubiquitous, has multiple sources, and can vary greatly over time and short distances.
