The road to animal-free glycosaminoglycan production: current efforts and bottlenecks.

Improving for Drum_Buffer_Rope material flow management with attention to second bottlenecks and free goods in a job shop environment

Drum–Buffer–Rope is a theory of constraints production planning methodology that operates by developing a schedule for the system’s first bottleneck. The first bottleneck is the bottleneck with the highest utilization. In the theory of constraints, any job that is not processed at the first bottleneck is referred to as a free good. Free goods do not use capacity at the first bottleneck, so very...

The Long Road to Eradicate Rinderpest

Genetic Relationships among Four Saudi Arabian Sheep Populations

Four Saudi Arabian indigenous sheep populations including Najdi, Hbsi, Arb, and Naemi were genotyped for 16 microsatellite markers recommended by the food and agriculture organization (FAO). This study aims to provide information on the genetic structure of the breeds analyzed and give indications and proposals for the cross breeding program. All loci were polymorphic in all populations and loc...

Biochemical and Physiological Changes during Thermal Stress in Bovines: A Review

The variation in climatic variables like temperature, humidity and radiations were recognized as the potential hazards in the growth and production of all domestic livestock species. Thermal environment is a major factor that can negatively affect both production and reproduction in dairy animals, especially in animals of high genetic merit. Among the stressors, heat stress has been of major co...
