Ethiopia has undergone a substantial shift in land use and land cover (LULC), which is home to the majority of the human and animal population.Land degradation has occurred in the Ethiopian highlands as a result of modifications in LULC caused by poor farming methods, high livestock population, and human pressures.Most researchers identified the ma
Energy-saving, punctuality and smoothness are difficult to achieve in the operation of heavy haul train.This paper proposes a multi-objective method for speed curve optimization.Firstly, a quadratic programming optimization model is established, using train kinetic energy and train force as independent variables and several goals of energy conserva
This study investigated the effect of various layer arrangements and their impact becksfabrics on the properties of laminated veneer lumber (LVL).Seven different layer arrangements (CCCCCCC, DDDDDDD, PPPPPPP, CDDDDDC, CPPPPPC, CDDCDDC, CPPCPPC, CDCDCDC, CPCPCPC, CCDDDCC, CCPPPCC, CCDCDCC, and CCPCPCC) were used in the manufacturing of the LVL, with
Introduction.Phenylketonuria is an inborn opi march in uniform metabolism error with a high phenotypical variability, due in part to the large number of implicated genetical variants (over 1200 reported) but also due to other factors.Establishing a genotype=phenotype correlation, accessible today through molecular testing, is an important instrumen
