Personal protective equipment (PPE) is an important part of worker protection during filovirus outbreaks. The need to protect against a highly virulent fluid-borne pathogen in the tropical environment imposes a heat stress on the wearer that is itself a safety risk. No evidence supports the choice of PPE employed in recent outbreaks, and standard testing procedures employed by the protective ga...

An analysis of technologies that allow creating microrelief structures on the surface sapphire substrates has been carried out. It is shown most effective method forming relief with submicron dimensions ion beam etching through a protective mask formed by photolithography. The main problems in are removal static electric charge process substrates, as well obtaining windows specified sizes, whic...

Background: Paraquat (PQ), an herbicide, is a very poisonous compound for both humans and animals. This study was conducted to examine the protective effect of the Coenzyme Q10 (CoQ10) in newborn rats from pregnant rats pre-treated with PQ. Methods: The experiments were conducted on 25 rats, divided in five groups randomly and equally: 1 - Control Group received normal saline (0.1ml/day); 2...

One challenge for geotechnical centrifuge testing of soil–structure interaction problems is the reliable measurement induced structural strains/forces. This paper presents a novel application fibre Bragg grating (FBG) sensors strain within tests. FBG have several advantages testing, in particular their small size and minimal self-weight. gives an overview recently developed installation calibra...

Urocanic acid is a major ultraviolet (UV)-absorbing chromophore. Chitins are highly crystalline structures that are found predominantly in crustacean shells. Alpha-chitin consists of microfibers that contain nanofibrils embedded in a protein matrix. Acid hydrolysis is a common method used to prepare chitin nanofibrils (NFs). We typically obtain NFs by hydrolyzing chitin with acetic acid. Howeve...

Corrosion of reinforcement is one the main problems related to durability reinforced concrete structures. This can cause cracks and a separation protective layer, as well reducing strength structural stiffness, which result in numerous human casualties. Visual inspection standard method assessing condition structures whose limitations, such time, interpretability, accessibility, etc., may affec...

Abstract The defect detection of thermal protective structures is great significance in ensuring the safe flight aircraft. In this paper, a dynamic measurement method based on planar capacitance sensing principle proposed to solve problem detecting defects adhesive layer large-area protection structures. This paper analyses capacitive and establishes array system. dielectric distribution struct...

Poutiainen, Piritta 2012. Comparison of impact characteristics of different ice hockey arena dasher boards. Department of Biology of Physical Activity, University of Jyväskylä. Master ́s Thesis in Biomechanics, 65 pp. During last years the incidence and severity of ice hockey related concussions have been increased and, hence, something should be done to stop this growth. The main aim of this st...

the present study was conducted to evaluate the protective effect of methanolic leaf extract of caesalpinia bonduc (l.) on gentamicin-induced hepatotoxicity and nephrotoxicity in rats . a control group (saline, group i, n = 6) was compared with rats administrated 80 mg/kg gentamicin, once daily for 7 days (groups ii, iii and iv). the effect of methanolic leaf extract of caesalpinia bonduc (grou...

BACKGROUND Little is known about the extent of human isocyanate skin exposure in auto body shops and the effectiveness of personal protective equipment. Animal studies have suggested that skin exposure to isocyanates may be an important risk factor for respiratory sensitization leading to asthma. This study provides initial data on hexamethylene diisocyanate skin exposure in three auto body sho...
