Regulation of type 1 fimbriae synthesis and biofilm formation by the transcriptional regulator LrhA of Escherichia coli

2005

Type 1 fimbriae ofEscherichia colifacilitate attachment to the host mucosa and promote biofilm formation on abiotic surfaces. The transcriptional regulator LrhA, which is known as a repressor of flagellar, motility and chemotaxis genes, regulates biofilm formation and expression of type 1 fimbriae. Whole-genome expression profiling revealed that inactivation oflrhAresults in an increased expression of structural components of type 1 fimbriae.In vitro, LrhA bound to the promoter regions of the twofimrecombinases (FimB and FimE) that catalyse the inversion of thefimApromoter, and to the invertible element itself. TranslationallacZfusions with these genes and quantification offimEtranscript le…

On-chip purification of arc-discharge synthesized multiwalled carbon nanotubes via mobile liquid interface

2017

This thesis reports a novel approach for purification of carbon nanotube (CNT) samples deposited on smooth silicon substrates through a mobile liquid interface interacting with carbonaceous debris particles that contaminate the deposition. The method is based on physical interaction of the particles and the three-phase contact line via capillary interface forces, i.e. the surface tension, which results in the detachment of chemically indispersible colloids from the sample surface. In the experiments reported in this work, we focus primarily on arc-discharge grown multi-walled carbon nanotubes, whose synthesis is particularly plagued by carbonaceous debris that is difficult to remove without h…

Resource Allocation and Computation Offloading for Wireless Powered Mobile Edge Computing

2022

In this paper, we investigate a resource allocation and computation offloading problem in a heterogeneous mobile edge computing (MEC) system. In the considered system, a wireless power transfer (WPT) base station (BS) with an MEC sever is able to deliver wireless energy to the mobile devices (MDs), and the MDs can utilize the harvested energy for local computing or task offloading to the WPT BS or a Macro BS (MBS) with a stronger computing server. In particular, we consider that the WPT BS can utilize full- or half-duplex wireless energy transmission mode to empower the MDs. The aim of this work focuses on optimizing the offloading decision, full/half-duplex energy harvesting mode and energ…

Pacientu ar apakšstilba kaula lūzumu līdzestība aprūpē pēc ķirurģiskas vai neķirurģiskas ārstēšanas metodes

2018

Bakalaura darba tēma ir “Pacientu ar apakšstilba kaula lūzumu līdzestība aprūpē pēc ķirurģiskas vai neķirurģiskas ārstēšanas metodes”. Tēmas aktualitāti nosaka lūzumu statistika – 2016. gadā no visām Latvijā reģistrētajām traumām, visvairāk reģistrēti tieši lūzumi. Apakšstilba kaula lūzumi ir visai izplatīti – tie veido aptuveni 10% no visu kaulu lūzumiem. Pētījuma mērķis ir izpētīt pacientu ar apakšstilba kaula lūzumu līdzestību aprūpē pēc ķirurģiskas vai neķirurģiskas ārstēšanas metodes. Pētījuma uzdevumi ir izpētīt zinātnisko literatūru par apakšstilba kaula lūzumu un pacientu līdzestību ārstēšanās un atveseļošanās procesos. Raksturot Kalistas Rojas adaptācijas teoriju, un saistīt to ar …
