We analyze the first-year MACHO collaboration observations of microlensing towards the Galactic center using a new direct likelihood technique that is sensitive to the distribution of the events on the sky. We consider the full set of 41 events, and calculate the direct likelihood against a simply-parameterized Galactic model consisting of either a gaussian or exponential bar and a double expon...

The application of membranes in various industries is one of the most urgent needs to reduce energy consumption and environmental pollutants as well as low investment costs in the process of separation. In this investigation, the optimization of effective parameters for separation of gas mixture of CH4, CO2, O2 and N2 is studied by modified poly(4-met...

Significantly more occlusion bodies (OB) of DuPont viral construct HzSNPV-LqhIT2, expressing a scorpion toxin, were transported by artificial rainfall to cotton plants from sandy soil (70:15:15 sand-silt-clay) than from silt (15:70:15) and significantly more from silt than from clay (15:15:70). The amounts transported by 5 versus 50 mm of precipitation were the same, and transport was zero when...

The characterization of soft or low impedance materials is of increasing importance since these materials are commonly used in impact and energy absorbing applications. There is a need to measure the high-rate material properties of soft materials, where the mode of loading is predominantly compressive and large deformations may occur at high rates of deformation. Importantly, the competing eff...

salvia genus has 58 annual and perennial herbaceous species in iran that 17 species are endemic and salvia sahendica boiss & buhse is one of them. in order to investigate the effects of drought stress caused by peg 6000 and salinity stress induced by nacl on germination factors of salvia sahendica, two experiments were carried out based on a completely randomized design with 3 replications. in ...

In this work, a study of possible molecular states from the $\Lambda_c\bar{\Lambda}_c$ interaction and their productions in nucleon-antinucleon collision is performed quasipotential Bethe-Salpeter equation approach. Two bound with quantum numbers $J^{PC}=0^{-+}$ $1^{--}$ are produced almost same binding energy which described by light meson exchanges. However, result does not support assignment...

Objective To test whether standard information for patients using Crunchie and Aero chocolate bars to explain bone health and risk of fracture is robust. Design Observational study. Setting Domestic kitchen in rural west Wales. Participants 10 Crunchie bars and 10 Aero bars. Main outcome measure Fracture after falls from varying heights. Results Both Crunchie and Aero bars exhibited the same T ...

Using $448.1\times 10 ^6$ $\psi(3686)$ decays collected with the BESIII detector at BEPCII $e^+e^-$ storage rings, branching fractions and angular distributions of $\chi_{cJ}\to\Xi^-\bar{\Xi}^+$ $\Xi^0\bar{\Xi}^0$ $(J = 0, 1, 2)$ are measured based on a partial-reconstruction technique. The $\chi_{c1}\to\Xi^0\bar{\Xi}^0$ $\chi_{c2}\to\Xi^0\bar{\Xi}^0$ observed for first time statistical signifi...

By most accounts (1 ), the development of bar code technology is credited to 2 graduate students at Drexel University. In 1948, Bernard Silver had overheard the president of a local grocery chain asking a dean at the University whether they could develop a system to read product information at checkout. Silver told his colleague Norman Woodland of this request. After one failed idea involving u...
