Graphs are often used as models to solve problems in computer science, mathematics, and biology. A pancake sorting problem is modeled using a graph whose classes include burnt graphs, signed permutation restricted graphs. The network cost degree × diameter. Finding with small like finding good algorithm. We propose novel recursively divided (RDP) that has smaller than other pancake-like In the ...

We consider the following single-machine time-dependent scheduling problem with constraints on the machine availability. There is given a set of independent and deteriorating jobs Jj , 1 ≤ j ≤ n, to be processed on a single machine, starting from time t0 > 0. The processing time pj of job Jj is a proportional function of the starting time Sj of this job, pj = αjSj, where Sj ≥ t0 and deteriorati...

Eight ruminally cannulated steers (BW = 753 +/- 48 kg) were used to evaluate in situ N, NDF, and DM degradation characteristics of by-product feeds and their application for beef cows consuming low-quality forage. Experimental feedstuffs included (DM basis) 1) extruded-expelled cottonseed meal (ECSM; 33% CP and 55% NDF), 2) extruded-expelled cottonseed meal with linters (ECSML; 25% CP and 41% N...

To encourage health professionals to raise the issue of alcohol among patients and to provide better advice to reduce hazardous drinking, Swedish health authorities implemented the Risk Drinking Project (RDP) between 2004-2009. The main activities were training seminars focusing on teaching motivational interviewing and screening for risky drinking. To evaluate the impact of RDP, baseline and f...

OBJECTIVE "Ischemic tolerance" can be induced in the retina by "preconditioning" with brief periods of non-injurious retinal ischemia or systemic hypoxia. The present study was undertaken to assess whether tolerance can be induced pharmacologically by deferroxamine (DFX), an iron chelator, which promotes the expression of the transcription factor, hypoxia-inducible factor 1-alpha (HIF-1alpha), ...

Metabolizable protein (MP) supply and amino acid balance in the intestine were manipulated through selection of highly digestible rumen-undegradable protein (RUP) sources and protected methionine (Met) supplementation. Four ruminallycannulated, multiparous Holstein cows averaging 193±13 days in milk were used in a 4×4 Latin square design to assess N utilization and milk production responses to ...

PURPOSE Long-term health risks of occupational exposures to uranium processing were examined to better understand potential differences with uranium underground miners and nuclear reactor workers. METHODS A cohort study of mortality of workers from Port Hope, Canada (1950-1999) and Wismut, Germany (1946-2008) employed in uranium milling, refining, and processing was conducted. Poisson regress...

The objective of this meta-analysis was to quantitatively summarize variations in urea kinetics related ruminant species, diet composition, and ruminal fermentation. A database 31 studies measuring recycling were used derive 2 sets linear mixed-effects regression models. Study as a random intercept regressions weighted by 1 divided the standard error mean observation. Models compared, when appr...

Las competencias tecnológicas distintivas se han convertido en un determinante de la competitividad empresarial. Redes Petri (RdP) resultan muy útiles al modelar una sucesión acciones, sus requerimientos, y las restricciones que puedan presentarse procedimiento. El objetivo del trabajo es el modelado análisis a partir redes flujo trabajo, derivadas RdP clásicas, procedimiento para determinación...
