This study underscores the critical importance of integrating engineering and geological assessments at various stages of dam construction. Re-evaluating and addressing evolving foundation conditions, particularly during construction, is essential for applying effective treatments to prevent dam failure during operation.

Recently, Structural Health Monitoring (SHM) has become a critical component of the maintenance and safety of lifeline infrastructures such as dams, skyscrapers, and bridges, thanks to its ability to detect structural failures at the early stages. In this paper, we evaluate the performance of the SHM damage identification tool using a novel metaheuristic algorithm called the Artificial Hummingbird Algorithm (AHA).

The main aim of this research is to develop a viable solution to treat and reuse car wash wastewater. To do so, two treatment systems were evaluated. The first treatment system comprised of coagulation-flocculation and ceramic ultrafiltration membrane and reverse osmosis and the second treatment system is enhanced membrane bioreactor (eMBR).

This paper presents a Bayesian approach based on integral experiments to create correlations which do not appear with differential data. Some quantities such as the fission cross section (s), neutron multiplicity (n¯p), neutron spectra (x), etc. are usually neither modeled together nor measured in coincidence, thus there is no correlation matrices in evaluated nuclear data libraries.

This article shows how the most recent gadolinium cross sections evaluations appear inadequate to provide accurate criticality calculations for a system with gadolinium fuel pins. In this article, a sensitivity and uncertainty analysis (S/U) has been performed to investigate the effect of gadolinium odd isotopes nuclear cross sections data on the multiplication factor of some LWR fuel assemblies.

This work makes use of the Generalized Least Square method to solve Bayes equation, as implemented in the CONRAD code. Experimental database used includes ICSBEP Uranium based critical experiments and benefits from recent re-analyses of MASURCA and FCA-IX criticality experiments (with Monte-Carlo calculations) and of PROFIL irradiation experiments.

The management of dairy farming has been historically based on experience and the skills the farm operator has in planning and decisions made. In cases where the farm has large herds, a farming system must be in place, thereby bring an evolution in dairy management, which is datadriven. Precision technologies can bring about increased efficiency and decision making in dairy management. Total farmers that have already adopted the technology is still relatively low, although data shows a growth in the adoption rate.

The importance of two putative Zn2+-binding (Asp347, Glu429) and two catalytic (Arg431, Lys354) residues in the tomato leucine aminopeptidase (LAP-A) function was tested. The impact of substitutions at these positions, corresponding to the bovine LAP residues Asp255, Glu334, Arg336, and Lys262, was evaluated in His6–LAP-A fusion proteins expressed in Escherichia coli. Sixty-five percent of the mutant His6–LAP-A proteins were unstable or had complete or partial defects in hexamer assembly or stability. The activity of hexameric His6–LAP-As on Xaa-Leu and Leu-Xaa dipeptides was tested.

In order to determine the amino-terminal sequence requirements for protein N-myristoylation, site-directed mutagenesis of the N-terminal region was performed using tumor necrosis factor (TNF) mutants as model substrate proteins. Subsequently, the susceptibility of thesemutants to protein N-myristoylation was evaluated by metabolic labe-ling in anin vitrotranslation systemusing rabbit reticulocyte lysate. A TNF mutant having the sequence MGAAAAA AAA at its N-terminus was used as the starting sequence to identify elements critical for protein N-myristoylation....

The enzymatic kinetics of glycoside hydrolase family 7 cellobiohydrolase (Cel7A) towards highly crystalline celluloses at the solid–liquid interface was evaluated by applying the novel concept of surface density (q) of the enzyme, which is defined as the amount of adsorbed enzyme divided by the maximum amount of adsorbed enzyme.

Interpreting, like playing chess, is a game of problem solving, evaluation, critical thinking, intuition and forecasting. Every game is different and each game is a challenge, which requires interpreters, to unceasingly develop knowledge and experience. It is disciplined study and repeated practice of many techniques and skills that bring victory to the interpreter. Apart from basic requirements of language mastery and culture sensitivity, there are quite a few skills that need to be acquired for successful interpreting. One of them is note-taking skill....

Despite its clinical importance, a dearth of information exists on the cellular and molecular mechanisms that underpin brain stem death. A suitable neural substrate for mechanistic delineation on brain stem death resides in the rostral ventrolateral medulla (RVLM) because it is the origin of a life-and-death signal that sequentially increases (pro-life) and decreases (pro-death) to reflect the advancing central cardiovascular regulatory dysfunction during the progression towards brain stem death in critically ill patients.
