Frequency of abortions recorded through Dairy Herd Improvement (DHI) testing was summarized for cows with lactations completed from 2001 through 2009. For 8.5 million DHI lactations of cows that had recorded breeding dates and were >151 d pregnant at lactation termination, the frequency of recorded abortions was 1.31%. Effects of year, herd-year, month, and pregnancy stage at lactation terminat...

Seminal plasma is composed of secretions from accessory sex glands, which are mixed with sperm at ejaculation and contribute the majority of semen volume. Seminal plasma is considered a transport and support medium for sperm in the female reproductive tract. Because seminal plasma is not required for fertilization, the importance of its constituents to the establishment of normal pregnancy has ...

Isometric twitch and tetanus parameters, force-velocity curves, maximum shortening velocity (Vmax) and percentage relaxation between stimuli (%R) across a range of stimulus frequencies were determined for a muscle used during call production (the tensor chordarum) and a locomotor muscle (the sartorius) for three species of hylid frogs, Hyla chrysoscelis, H. versicolor and H. cinerea. The call o...

A random number of vehicles crossed a transverse line of a highway during an arbitrary interval of time and a random number of vehicles situated on an arbitrary part of the highway at a fixed instant of time form a complicated stochastic dependence. In case of bad weather and bad road conditions the spatial intervals between the neighbouring vehicles at a fixed instant of time (a spatial charac...

In this paper, we present two New models named New-Weibull-Weibull ($NWW$) and New-Weibull-Rayleigh ($NWR$) from The New-Wei- bull-G family recently introduced that can have a variety of hazard rate shapes allows to describe observations different fields study. unknown parameters the $NWW$ $NWR$ been estimated under maximum likelihood estimation method. Moreover, construct modified chi-squared ...

Anaerobic ammonium oxidation (anammox) converted into nitrogen gas using nitrite as an electron donor in anaerobic conditions by anammox bacteria. Granular was used commonly to remove from wastewater. It easy be broken and tend settle the bottom of reactor application. A pored ceramic carrier proposed cultivate bacteria with two-inflow substrate feeding. The a diameter 1.0 mm set up center L co...

In this study, TiO2 nanosheets (NSs) grown in situ on extremely conductive Ti3C2Tx MXene to form TiO2/Ti3C2Tx composites with abundant active sites are proposed effectively achieve electrocatalytic NH3 synthesis. Electron transfer can be promoted by high conductivity. Meanwhile, the NSs in-situ formation not only avoid microstacking but also enhance surface specific area of MXene. The catalyst ...
