the wet and dry spells can be defined as a number of consecutive months with rain amount greater or less than the truncation level, respectively.analysis of the wet and dry spell properties of monthly rainfall series at 40 meteorology stations in the golestan province is carried out for an extended period of 34 years (1974–2007). the results proved that the patterns of wet and dry spell duratio...

OBJECTIVES To evaluate the shear bond strength and site of failure of brackets bonded to dry and wet enamel. STUDY DESIGN 50 teeth were divided into ten groups of 5 teeth each (10 surfaces). In half the groups enamel was kept dry before bonding, and in the other half distilled water was applied to wet the surface after etching. The following groups were established: 1) Acid/Transbond-XT (dry/...

We have shown recently that antlers of red deer, at the time that they are used in fights in the rut, are essentially dry. We have also shown that dry antler material has a lower impact energy absorption than that of wet antler, a property which, in a fight, is probably very important in the first clashing of antlers. However, dry antler has a much higher Young’s modulus (stiffness) than wet an...

in order to simultaneously improve wet and dry strengths of paper and decrease environmental issues related to the wet strength resins, in this study effect of application method of wet strength additives on paper properties was investigated. wet strength resins were applied in four methods including spraying an aqueous glyoxal solution on to the surface of wet paper, addition of aminated polya...

BACKGROUND/AIMS With the increased efficacy of current therapy for wet age-related macular degeneration (AMD), better ways to detect wet AMD are needed. This study was designed to test the ability of three-dimensional contrast threshold Amsler grid (3D-CTAG) testing to distinguish wet AMD from dry AMD. METHODS Conventional paper Amsler grid and 3D-CTAG tests were performed in 90 eyes: 63 with...

Four swab materials were evaluated for their efficiency in recovery of Bacillus anthracis spores from steel coupons. Cotton, macrofoam, polyester, and rayon swabs were used to sample coupons inoculated with a spore suspension of known concentration. Three methods of processing for the removal of spores from the swabs (vortexing, sonication, or minimal agitation) and two swab preparations (premo...

OBJECTIVE • To measure urinary nerve growth factor (NGF) in women with overactive bladder (OAB)-dry and OAB-wet and investigate the association of urinary NGF expression with these factors. PATIENTS AND METHODS • Differentiation between OAB-wet and OAB-dry was based on symptoms and a 3-day voiding diary. • Urinary NGF levels were measured by enzyme-linked immunosorbent assay (ELISA). • The ur...
