Beta'-Lithiation of Alpha, Beta-Unsaturated Amides
The novel (beta)'-lithiation of (alpha)-alkyl-(alpha),(beta)-unsaturated secondary and tertiary amides is reported. N-Methyl-1-cyclohexenecarboxamide and N-methyl-1-cyclopentenecarboxamide are metalated at nitrogen and at the (beta)'-carbon with either sec-butyllithium/TMEDA at -78(DEGREES)C or …

A Comparative Study of Inductive Influence on the Hydrolysis of Beta-Thioglucopyranosides by Beta-Thioglucosidase and Beta-Glucosidase
A series of phenyl-D-thioglucopyranosides were prepared and characterized in order to determine the absolute specificity of the .B-thioglucosidase and B-glucosidese enzyme systems toward the th1oglucosidic bond. The specificity of B-glucosidase of almond emulsin toward oxygen linkage seems to be …

Efficacy of beta-hydroxy-beta-methylbutyrate (HMB) supplementation in hemodialysis patients
… to combat these co-morbidities are needed. Beta-hydroxy-beta-methylbutyrate (HMB) is a metabolite of the amino acid leucine that has been shown to improve lean mass and physical function in the elderly and clinical populations, but had not previously been studied in MHD patients. …

The design and structural characterization of oligomeric beta beta alpha mini-proteins
Oligomeric mini-proteins, short peptides with protein-like features, constitute valuable minimal models for the study of oligomeric proteins. Oligomerization is a common feature of cellular proteins that may confer structural and functional advantages. Oligomerization is proposed to have arisen by …

Beta-ensembles with covariance
This thesis presents analytic samplers for the [beta]-Wishart and [beta]-MANOVA ensembles with diagonal covariance. These generalize the [beta]-ensembles of Dumitriu-Edelman, Lippert, Killip-Nenciu, Forrester-Rains, and Edelman-Sutton, as well as the classical [beta] = 1, 2,4 ensembles of James, …

Synthesis and reactivity of alpha-thio-beta-chloroacrylamides and alpha-thio-beta-chloroenones
Development of novel synthetic methodology for selective transformation of organic compounds is a central element underpinning organic synthesis with control of chemo-, regio- and stereoselectivity a very high priority. Reactions which can be conducted under mild reaction conditions and, ideally in …

Higgs pair production in [beta][beta][tau][tau] final states at the HL-LHC
… of standard model Higgs pair production in [beta][beta][tau][tau] final states at the High Luminosity LHC is investigated. Higgs pair production can be used to measure the Higgs trilinear coupling constant, which uniquely determines the shape of the Higgs potential. The doubly hadronic, …

(n,nʹ[gamma]) reactions in 6̳3̳,̳6̳5̳Cu and background in 0[nu] [beta] [beta] experiments
… background for certain underground double beta decay experiments. Neutroninduced gammas are a contribution to background for the next generation of double beta decay experiments, which are designed to reach the sensitivity of the atmospheric neutrino mass scale (45 meV). Measuring and …

Beta-Gamma Directional Correlation Measurements
… will show a definite correlation with ->k1. In beta - gamma angular correlation studies a radioisotope emits in rapid succession a beta particle followed by a gamma-ray. The relative probability that the gamma-ray is emitted into the solid angle of a movable detector at an angle theta with …

The beta effect in alkylsilanes
… due to them possessing both an alpha group and a beta group. The aim of this research was to discover whether or not the alpha and beta effects interact with each other, and if so whether interaction is via steric or electronic effects. A series of compounds were made with a constant chloromethyl …
