globally excessive consumption of hydrocarbon fuel in transport sector is a serious threat to the civilization due to paucity of fuel in future. also this growing use of vehicles for transport is contributing about 70% of total air pollution and causing environmental and ecological imbalances. thus the worldwide fast depletion of conventional energy resources and impact of emissions on environm...

twenty eight lactating buffaloes were used in a completely randomized design with 2×2 factorial arrangement of four experimental diets including low protein–low energy (lp-le), low protein–high energy (lp-he), high protein–low energy (hp-le) and high protein–high energy (hp-he). results showed that the hp-he diet recorded the highest digestibility coefficients of cp, ee, nfe, nutritive values, ...

introduction: as off pump coronary artery bypass grafting surgery (cabg) is a developing method in coronary cardiac surgery, most surgeons are anxious about the danger of emergency crash conversion. in this observational study we tried to show the rate and outcome of conversion . material and methods: in this descriptive study about 477 coronary off-pump cabg patients were operated in ghaem hos...

Diagnostic casts may help guide preimplant and treatment prosthodontics. Once the preimplant phase is satisfactory, prosthetically driven implant placement also must accommodate anatomical limitations, and possible adaptations of the original planning may be necessary. This set of requirements can be achieved using precise surgical guides. In recent years, advanced guidance has been developed t...

The yeast cytoplasmically inherited genetic determinant [PSI+] is presumed to be a manifestation of the prion-like properties of the Sup35 protein (Sup35p). Here, cell-free conversion of Sup35p from [psi-] cells (Sup35ppsi-) to the prion-like [PSI+]-specific form (Sup35pPSI+) was observed. The conversion reaction could be repeated for several consecutive cycles, thus modeling in vitro continuou...

The primary interest of this paper is in out-of-sample forecasting for the U.S. monthly unemployment rate. Several linear unobserved components models are fitted and their comparative forecasting accuracy is assessed by means of and extensive rolling-origin procedure using a test period that covers the last two decades. An attempt is made to link forecasting performance to the time domain prope...

The ultimate goal of Patternless Casting Manufacturing (referred to as PCM) is how to obtain the casts by casting the sand mold directly. In the previous PCM, the resin content of sand mold is much higher than that required by traditional resin sand, so the casts obtained are difficult to be sound and qualified products, which limits the application of this technique greatly. In this paper, the...

The importance of manuals certainly extends beyond their use in training and reference. In some sense (whether this is explicit or implicit) a user must ‘know’ what they are doing to use a system, and the manual is a representation of what they could know. Whether a user could in practice verbalise their knowledge as a system manual is unlikely — it may not even be necessary to be able to do so...

We present universal formulas for the spectral and temporal output optical fields from a linear traveling-wave medium whose refractive index changes during its propagation within the medium. These formulas agree with known changes in central wavelength and energy that are associated with adiabatic wavelength conversion (AWC). Moreover, they reveal new changes to the optical pulses that have not...

Intrachromosomal gene conversion is the non-reciprocal transfer of information between a pair of repeated genes on a single chromosome. This process produces eventual sequence homogeneity within a family of repeated genes. An evolutionary model for a single chromosome lineage was formulated and analyzed. Expressions were derived for the fixation probability, mean time to fixation or loss, and m...
