Permeated by rurality and urbanity, the routine of "temporary rural workers" is quite revealing to whom it proposes to investigate it. Temporally, is marked by linear time, but also by the cyclical time which refers to social processes of agrarian past. Spatially, it is centered on the threshold between country and city. This seizure was objectified by this work, possible only on the premise that space has three levels, namely, social, physical and mental. This sort, we make use of fruitful thinking of Henri Lefebvre, which spans disciplinary boundaries. To this must be the fact that, in this article, several fields of knowledge were explored, such as sociology, anthropology and geography. Moreover, efforts fell also on the labor relations field, usually marked by over - exploitation of temporary workers, commonly called "temporary rural workers, the sugar cane cultivation. The article is broken into two parts. At first, we deal with time and space in the routine of "temporary rural workers." The next moment, the discussions are directed at the seizure of rural and urban anthropology from a dialectic of ?temporary rural workers?.

The performances of five different ESI sources coupled to a polystyrene-divinylbenzene monolithic column were compared in a series of LC-ESI-MS/MS analyses of Escherichia coli outer membrane proteins. The sources selected for comparison included two different modifications of the standard electrospray source, a commercial low-flow sprayer, a stainless steel nanospray needle and a coated glass Picotip. Respective performances were judged on sensitivity and the number and reproducibility of significant protein identifications obtained through the analysis of multiple identical samples. Data quality varied between that of a ground silica capillary, with 160 total protein identifications, the lowest number of high quality peptide hits obtained (3012), and generally peaks of lower intensity; and a stainless steel nanospray needle, which resulted in increased precursor ion abundance, the highest-quality peptide fragmentation spectra (5414) and greatest number of total protein identifications (259) exhibiting the highest MASCOT scores (average increase in score of 27.5% per identified protein). The data presented show that, despite increased variability in comparative ion intensity, the stainless steel nanospray needle provides the highest overall sensitivity. However, the resulting data were less reproducible in terms of proteins identified in complex mixtures -- arguably due to an increased number of high intensity precursor ion candidates.
