Experimental models of in vitro testing of spinal fixation are limited by constraints on availability of cadavers, variations in quality of some structures, such as bone density and area of endplate preparation, implant location and fixation method [ 22].
Based on the significance of expression fold changes, constraints on availability of reliable genomic structure (exon/intron) information, and known gene functionality, 11 upregulated genes, 7 downregulated genes, and 3 control genes were selected for ChIP analysis (Table 1 and Supplementary Table S4) in 24 hpf WT embryos.
Thus, preference is a term that describes the individual's forage intake in the absence of any constraints on availability or accessibility [ 4].
Results show that at a macroscale it is important to consider the natural climatic constraints of water availability.
A hybrid inexact chance-constrained mixed-integer linear programming (ICCMILP) method is proposed, with an objective of maximizing economic return under constraints of resources availability and environmental regulations.
Multi-source and multi-temporal Remote Sensing (RS) images (including Landsat ETM+ (30 June 2001), SPOT imagery (21 November 2003 and 5 May 2008) and CBERS02 CCD (5 June 2006)) were used due to the constraints of the availability of remotely sensed data.
Several factors are forcing to address the issues of differentiated Quality of Service (QoS) and ubiquitous accessibility in Internet services, from growing user requirements to the increasing heterogeneity of access devices, from the competition of service providers to the severe constraints of resource availability in emerging wireless environments.
In order to satisfy the constraints of high availability and high site resilience, multiple mirror-infrastructures can be provisioned in different geographical locations (location constraints); however, the performance constraints may require low network latency between different sites.
Particularly, the scientific literature underlines the importance of the balance between a validated approach, reliability and significance of the indicators and the objectives to be achieved (Girardin et al. 1999), under the constraints of data availability.
At a macro-scale, it is important to consider the natural climatic constraints of water availability as well as the appropriate choice of species/varieties and associated forest management options that are suitable for water conservation.
