Sixty-four DurocxLandrace pigs (Sus scrofa) of both sexes were reared from birth to 6 weeks of age in either fresh air or an atmosphere containing an artificial odourant (Ambi-Pur). Their behavioural responses to a novel environment (a modified open field) were then observed over 1h when the test arena contained either the familiar Ambi-Pur odourant or ammonia gas at 45ppm. Although members of ...

INTRODUCTION We report the results of treatment of posterior urethral rupture (PUR) by primary realignment with some modifications of the technique. MATERIALS AND METHODS In this prospective study, 25 patients (mean age, 33.5 years; range, 18 to 70 years) in whom PUR had been proved underwent primary urethral realignment. All patients were evaluated postoperatively for urinary incontinence, e...

BACKGROUND The emergence of Clostridium difficile ribotype 027 raised the question of sporicidal surface disinfectants are also effective against spores of C. difficile ribotype 027. MATERIALS AND METHODS Three surface disinfectants based on magnesium monoperoxyphthalate hexahydrate (Dismozon pur), a combination of (ethylenedioxy)dimethanol, glutaral and benzyl-C12-18-alkyldimethylammonium ch...

The impact of cold temperatures on the shear strength of Scots pine (Pinus sylvestris) joints glued with seven commercially available adhesives was studied in this work. The cold temperatures investigated were: 20, −20, −30, −40, and −50 °C. Generally, within the temperature test range, the shear strength of Scots pine solid wood and wood joints were more resistant to the effect of temperature ...

In the present paper, fracture toughness of a polyurethane (PUR) foam (manufactured by Necumer GmbH, Germany, under commercial designation Necuron 651) is experimentally and numerically investigated in order to examine its dependence on specimen sizes. As matter fact, best knowledge authors, such an analysis still missing technical literature. To perform experimental campaign, notched PUR beams...

We measured in situ inherent optical properties and seagrass maximum depth distribution in widely differing optical water types, including turbid green waters of the Indian River Lagoon (IRL, Florida, USA), a mix of turbid and clear waters in Panama, and very clear waters in Belize. We used Hydrolight to model in situ spectral energy distributions and measured leaf absorbance spectra (Thalassia...

The genes encoding the enzymes of IMP biosynthesis in Bacillus subtilis constitute the pur operon, whereas the genes encoding GMP biosynthetic enzymes, guaA (GMP synthetase) and guaB (IMP dehydrogenase), and the purA gene encoding adenylosuccinate (sAMP) synthetase all occur as single units. The purB gene encodes an enzyme involved in both IMP and AMP biosynthesis and is located in the pur oper...

The studies were carried out to isolate the mango quick decline fungi from mango bark beetle, Hypocryphalus mangiferae S. collected from mango orchards of Nawab pur, Lutfabad and Faiz pur bhatian, Multan, Pakistan. Different life stages of H. mangiferae were collected from diseased mango trees and fungal isolations were carried out from each stage as well as from different body parts (head, tho...

The effects of adding an extra layer within a sandwich panel and two different core types in top and bottom cores on low velocity impact loadings are studied experimentally in this paper. The panel includes polymer composite laminated sheets for faces and the internal laminated sheet called extra layer sheet, and two types of crushable foams are selected as the core material. Low velocity impac...
