INTRODUCTION Recent studies show similar outcome between surgery and conservative treatment in patients with non-obstructive meniscal tears. However, surgery is still often preferred over conservative treatment. When conservative treatment is non-inferior to surgery, shifting the current standard treatment choice to conservative treatment alone could save over €30 millions of direct medical cos...

Continuous development and increase of population in the urban areas, a series of problems related to environment such as deforestation, release of toxic materials, solid waste disposals, air pollution and many more, have attracted attention much greater than ever before. The problem of air pollution in cities has become so severe that there is a need for timely information about changes in the...

The integration between technology of remote sensing, information from the data of digital image, and modeling technology for the simulation of water quality will provide easiness during the observation on the quality of water changes on the river surface. For example, Ciliwung River which is contaminated with non-point source pollutant from household wastes, particularly on its downstream. Thi...

Petroleum substances are the main source of pollutants stored in old waste pits. They cause degradation of biological life in the area of storage. The aim of this article is to present laboratory research on petroleum pollutant biodegradation. The hydrocarbon contaminants in old drilling wastes came from the Graby-19 waste pit. The tests included basic bioremediation and inoculation with a biop...

The low-dose effect and non-monotonicity hypotheses challenge key concepts in eco-toxicology and risk assessment, and also the possibility to predict the effects of a chemical at low levels of exposure from its effects at higher levels of exposure. Low-dose effects and Non-Monotonic Dose-response Curves (NMDRC) provides situations to understand impacts for toxicological risk assessment paradigm...

Identification of the specific pollutants contributing most to the health hazard of the air pollution mixture may have important implications for environmental and social policies. In the current study, we conducted a time-series analysis to examine the specific effects of major air pollutants [particulate matter less than 10 microns in diameter (PM(10)), sulfur dioxide (SO(2)), and nitrogen di...

Abstrae--The normal-mode-expansion technique is used to obtain a semi-analytical solution for the angular distribution of radiation at any optical distance within a linearly anisotropicscattering, absorbing, emitting, non-isothermal, gray medium between two parallel reflecting boundaries. Both conservative and nonconservative cases are considered. The general problem is decomposed into simpler ...

background: seroma formation is a common complication after breast cancer surgery. several techniques such as tube drainage, fibrin sealant and suturing methods have been employed to prevent or reduce seroma formation. capitonnage, a suturing method widely used following hydatid cyst removal, has been used after breast surgery in limited studies. our aim was to compare the effectiveness of tube...

background: several effects of volatile organic compounds (vocs) have been recognized such as toxic and carcinogenic human health effects. to evaluate cancer risk of benzenes air samples were taken, at an automobile manufacturing painters in tehran following inhalation exposure. methods: to perform this study, cross-sectional was done in 2016. sampling was carried out by active pump sampler usi...
