Abstract:
ABSTRACT Microcin B17 (MccB17) is a peptide antibiotic produced by Escherichia coli strains carrying the pMccB17 plasmid. MccB17 is synthesized as a precursor containing an amino-terminal leader peptide that is cleaved during maturation. Maturation requires the product of the chromosomal tldE (pmbA) gene. Mature microcin is exported across the cytoplasmic membrane by a dedicated ABC transporter. In sensitive cells, MccB17 targets the essential topoisomerase II DNA gyrase. Independently, tldE as well as tldD mutants were isolated as being resistant to CcdB, another natural poison of gyrase enco

TldD and TldE proteins interact and form a complex to degrade unfolded peptides. The gene Tk0499 from Thermococcus kodakarensis encoded a putative modulator of gyrase (TkTldE).

Here, the three-dimensional structure of TkTldE was determined by X-ray diffraction. Crystals were acquired by the sitting-drop vapor-diffusion method.

Integrating existing liquid storage and supply tanks in buildings with tuned liquid dampers (TLDs) are significant for reducing the effective cost of TLDs.

To overcome this problem, a passive liquid control system named TLD with a stable replenishment sub-tank system (TLD-SRS) is proposed.

Thermoluminescence dosimeters (TLDs) are widely used for both personal and environmental dosimetry. TLDs should have high accuracy under different conditions. The TL signal can drop over time because of fading (loss of signal due to thermally induced recombination of trapped charriers), thus leading to underestimation of the irradiation dose. The Saudi climate is extremely hot for most of the year, which could significantly affect TLD measurements. Therefore, the effect of ambient temperature, storage time and irradiation dose were investigated both in laboratory controlled-temperature conditi

As buildings become taller and slenderer, managing their vibrational response and mitigating it pose significant challenges in design.

However, the dynamic behavior of TLDs and their interaction with structures is complex.

Abstract:
Commodity-based and vehicle-trip-based freight demand modeling is discussed. The characteristics of the trip length distributions (TLDs) are examined, defined in terms of tons, as required in commodity-based modeling, and in vehicle trips, as required in trip-based modeling. With data used from a major transportation study in Guatemala, the TLDs are estimated for both tons and vehicle trips. The analysis revealed that ( a) the shape of the TLDs depends upon the type of movements being considered; ( b) TLDs defined in terms of tonnage differ significantly from those defined in terms of vehicle

This paper focuses on the wind-induced vibration control of the Dalian international trade mansion (DITM) by using the tuned liquid dampers (TLDs).

The wind loading is subsequently simulated by the Davenport model according to the structural environmental condition where the actual samples of wind speed are measured. Following

A 1: 200 scaled model of an aeroelastic tall building was built, and TLCD models of mass ratio of 1.5% and 3%, respectively, were designed and tested with the aeroelastic model.

In order to solve the shortcomings of traditional TLDs (tuned liquid dampers), such as their narrow frequency bands and their occupation of large amounts of space, based on deep-water theory, a new type of TLD incorporating Karmen vortex street theory is proposed and named as KV-TLD. A shaking table experimental test is conducted to fully analyze its vibration damping characteristics and its effectiveness in terms of vibration control is confirmed.

Relative deviation between doses measured with TLDs and doses stated by RT centre should not exceed 3%. During 2015–2017, all Czech RT centres equipped with modern linear accelerators were subjected to this more advanced TLD audit. A total of 70% of participants complied with the limit of 3% in the fi
