The current study investigated the effect of boric acid (H3BO3) nanosized powder on optical properties a Computer-Aided Design and Manufacturing (CAD-CAM) polymer infiltrated ceramic material. Specimens (n = 60), (15 × 8 1.5 mm3) were fabricated from network (PINC) (Vita Enamic, Vita Zahnfabrik, VITA-shade scale A2). Boric (B) nano was applied to Enamic in half specimens 30), while other left u...
OBJECTIVES: Topical antiseptics and antifungal agents are frequently used for the treatment of otomycosis. Topical use of boric acid solution in alcohol is also recommended, and some studies report its clinical efficacy. However, there are no studies in the English literature concerning the in vitro efficacy of boric acid salts on fungi isolated from the ears with otomycosis. In this study, we ...
the aim of this research was to evaluate the influence of rooting cofactors including hydrogen peroxide, boric acid and thiamine along with indole-3-butyric acid (iba) on rooting of olive cuttings cv. rashid in autumn 2007 and spring 2008. the study was carried out as a factorial experiment in a completely randomized design (crd) with three replications, and five cuttings in each replication. r...
Boric acid dust treatments were evaluated as a tool for the integrated management of the German cockroach, Blattella germanica (L.), in commercial confined swine production. The efficacy of boric acid dust was comparable to that of an organic residual insecticide, cyfluthrin, which is commonly used to control cockroaches in this environment. Fall treatments suppressed the cockroach population f...
Pistachio is one of the most important nuts and its mass production using tissue culture techniques is of great importance. Micro-propagation has many complications. Contamination is one of the critical limitations in the establishment stage. This study focused on different NaClO and HgCl2 concentrations and exposure times. Shoot tip necrosis (STN) is one of the most common problems during larg...
X-ray powder diffraction studies along with complementary Raman and infrared spectroscopy measurements disclosed the pressure-induced chemical decomposition of boric acid, H3BO3. The layered triclinic structure of H3BO3 suffers a highly anisotropic compression associated to a strong reduction of the interlayer spacing. The starting structure becomes unstable at about 2 GPa and decomposes on a c...
The objectives of this study were: to evaluate the leaching potential B in a Latossolo Vermelho-Amarelo (Oxisol) as function sources and doses micronutrient; among tested (boric acid, ulexite commercial source H2 Boro), determine one with lowest potential; losses at different each soil layer evaluated; identify chemical physical variables soils that influence leaching. For that, two experiments...
We studied B adsorption on amorphous aluminum and iron hydroxides, allophane, and kaolinite as a function of pH and initial B concentration. Boron adsorption lowered the point of zero charge of all four adsorbents, implying specific adsorption (inner-sphere complexation) of B. We provided novel information on the coordination of B adsorbed at mineral-water interfaces by attenuated total reflect...
Saprolegnia infections cause severe economic losses among freshwater fish and their eggs. The banning of malachite green increased the demand for finding effective alternative treatments to control the disease. In the present study, we investigated the ability of boric acid to control saprolegniosis in salmon eggs and yolk sac fry. Under in vitro conditions, boric acid was able to decrease Sapr...
