Using a high-statistics sample of neutral current elastic neutrino interactions, MiniBooNE measured the fluxaveraged neutral current elastic differential cross-section on mineral oil (CH2). Using the latter, a χ2 test of MC with different values of the axial vector mass has been performed. Also, a possibility of using a sample of neutral current elastic protonenriched events above Cherenkov thr...
The paper discusses mineral water consumer market and development policy in Georgia, the tools and measures, which will contribute to production of mineral waters and increase its export. The paper studies and analyses current situation in mineral water production sector as well as the factors affecting increase and reduction of its export. It’s noted that in order to gain and maintain competit...
OBJECTIVES A longitudinal study was conducted to investigate the relationships of the change in radius bone mineral density for seven years with lifestyle, body measurement data and laboratory data. METHODS The subjects of this study were 191 female employees working in an LSI manufacturing factory in Japan. Bone mineral density was measured on the radius of their nondominant side using DXA (...
OBJECTIVE To estimate how axial rotation of lumbar vertebrae quantitatively affects bone mineral density, as measured by dual energy X-ray absorptiometry in the anteroposterior plane. DESIGN Observational study. SETTING University teaching hospital, Hong Kong. PATIENTS Cadaver lumbar vertebrae (L2 to L4) were removed from four adults. MAIN OUTCOME MEASURES Using dual energy X-ray absorp...
The effect of kadosero, a crude mineral used by traditional healers as a supplement to plant extracts against microbial infections was evaluated. A sample of kadosero from a local market was both analyzed for its basic composition and its role on bioactivity of plant extract. Titrimetric, Gravimetric and Atomic Absorption Spectrometric analyses were used to determine contents of the mineral kad...
Many animals in the tropics of Africa, Asia and South America regularly visit so-called salt or mineral licks to consume clay or drink clay-saturated water. Whether this behavior is used to supplement diets with locally limited nutrients or to buffer the effects of toxic secondary plant compounds remains unclear. In the Amazonian rainforest, pregnant and lactating bats are frequently observed a...
Background and aims. Mineral trioxide aggregate and calcium hydroxide are considered the gold standard pulp-capping materials. Recently, Portland cement has been introduced with properties similar to those of mineral trioxide aggregate. Histopathological effects of direct pulp capping using mineral trioxide aggregate and Portland cements on dog dental pulp tissue were evaluated in the present s...
Intensified mineral consumption and reserve depletion means that it is becoming increasingly important for policymakers to account for and manage national mineral capital. Exergy replacement costs (ERC), an indicator based on the second law of thermodynamics, provides a physical value of mineral loss. When only a unit mass analysis is used, the role of scarcer minerals, such as gold, is obscure...
