Given a rectangle A and a set S of n points in A, the maximum empty rectangle problem is that of finding a largest-area rectangle which is contained in A. has its sides parallel to Ihose ofA. and does Dot contain any of the points in S. This Dote describes an efficient algorithm for solving this problem.

In this working paper the regional impacts of road pricing on cars are analysed taking into account externality effects from transportation on wages and productivity. In the paper the direct impacts from changes in transport costs on level of wages and productivity (=direct externality effects) have been estimated. The direct and derived impacts of road pricing have been analysed with AKF's loc...

When working with hot mix asphalt, road pavers are exposed to polycyclic aromatic hydrocarbons (PAHs) through the inhalation of vapors and particulate matter (PM) and through dermal contact with PM and contaminated surfaces. Several PAHs with four to six rings are potent carcinogens which reside in these particulate emissions. Since urinary biomarkers of large PAHs are rarely detectable in asph...

BACKGROUND/AIM Cardiovascular morbidity and mortality are markedly increased in chronic renal failure (CRF). The aim of this study was to evaluate lipid parameters and bioindices in patients with different stages of CRF. METHODS In 46 hemodialysed (HD), 50 CRF patients with II, III and IV stage of CRF (non-HD) and 48 control subjects triglycerides (TG), total cholesterol (C), HDL-C, urea, cre...

In the past 40 years, cultivated land has faced continued anthropogenic interference, which become a significant issue for preservation during rapid urbanization. The purpose of this research was to reveal spatio-temporal evolutionary characteristics and correlation between rural population variation farmland change in China. Fifty county-level administrative units Zhejiang Province were select...

Forests play an irreplaceable role in preserving soil and water, as well realizing carbon neutrality. However, logging urban expansion have caused widespread forest fragmentation globally, resulting biodiversity loss emissions. Therefore, it is a prerequisite to develop comprehensive index for evaluating the degree of propose effective policies protection restoration. In this study, (FFCI) was ...

GPR55 is a seven transmembrane G protein-coupled receptor and was originally identified as a putative third cannabinoid receptor. Recently, lysophosphatidylinositol (LPI) was reported to be a GPR55 ligand. Stimulation of GPR55 by LPI activates G(12/13) and G(q/11) proteins, induces phosphorylation of the extracellular signal-regulated kinase and increases intracellular calcium concentration. Ly...
