The vitamin B₁₂ concentrations in both the water and sediments
of Klamath Lake were found to vary significantly during a
one-year period. The patterns of B₁₂ distribution were remarkably
similar among the three main sites. In all cases there was an extremely
sharp gradation in concentration in relation to depth...
Forecasting of ocean waves over a short duration on the order of tens of seconds was approached with the optimization of wave energy conversion in mind. This study outlines the development of an artificial neural network model, specifically the Nonlinear Autoregressive Network with Exogenous Input (NARX), to predict a wave-by-wave...

In the United States, the utilization of digital media has assumed an omnipresent status and has altered the manner in which we communicate, conduct business, and create art and music. However, it has been demonstrated that art therapy lags behind the current culture of prolific use of digital media. To...
The Accounting Education Change Commission (AECC) is
a consortium of concerned accounting professionals and
accounting educators that advocates the redesigning of

The mycosporins, formerly called P310's are secondary metabolites
of fungi closely associated with fungal reproductive processes that
require light. The structurally related iminomycosporins are found in
marine plants and animals and may also have functions related to
light. In this study, approaches toward the asymmetric synthesis of
the mycosporins are...
The stage of dormancy development at which deciduous nursery
stock can be safely defoliated for harvest was investigated in red-osier
dogwood (Cornus stolonifera Michx.). This stage, previously called
"vegetative maturity," was found to correspond to the onset of winter
dormancy in red-osier dogwood. A reduction in ethylene production

Semen characteristics and egg production of male and female
commercial broiler breeders maintained in cages or on litter floors

The reaction of cyclodeca-1,215triene with mercuric salts
gave only rearranged hydrocarbon, tricyclo[4.4.0.0²'⁴]deca-5ene
in acetic acid. Other catalysts [Rh(CO)₂C1]₂ and AgC10₄ gave
the same rearranged hydrocarbon. The isomerization is proposed
to proceed through a "metalcomplexed" carbenoid intermediate.
The reaction of bicyclo[7.1.0 ]deca-213diene gave
oxymercurated products.
The relationship between self-concept and teacher competency
was examined among 29 female college students enrolled in a

Anthozoa-class red fluorescent proteins (RFPs) are frequently used as biological markers, with far-red (lambda(em) similar to 600-700 nm) emitting variants sought for whole-animal imaging because biological tissues are more permeable to light in this range. A barrier to the use of naturally occurring RFP variants as molecular markers is that...
The bivalve Pacific geoduck (Panopea generosa) has been used in the eastern North Pacific Ocean to create proxies for environmental factors such as temperature and oceanographic conditions. This type of research depends upon accurate age determination of Pacific geoducks, which historically was based on shell growth-increment counts. A recent study...

The action of a medicine may be less predictable in an older person and its intended action may be altered. Sometimes the effect is insignificant; other times it can be dramatic.
Medicines today are powerful chemicals that are more effective than ever before. Used carefully they can work wonders. However, both prescription and over-the-counter (nonprescription) medicines can create problems, especially if misused or abused. You probably try to find out about movies and restaurants before going to them, how to use...

Selenium (Se) is an essential micronutrient in cattle, and Se-deficiency can affect morbidity and mortality. Calves may have greater Se requirements during periods of stress, such as during the transitional period between weaning and movement to a feedlot. Previously, we showed that feeding Se-fertilized forage increases whole-blood (WB) Se concentrations...
