Comments on "Solubility and Dissolution Thermodynamic Data of Cefpiramide in Pure Solvents and Binary Solvents" (open access)

Comments on "Solubility and Dissolution Thermodynamic Data of Cefpiramide in Pure Solvents and Binary Solvents"

Abstract: Errors are found in the mathematical correlation based on the combined Jouyban-Acree and Modified Apelblat model for describing the variation in the mole fraction solubility of cefpiramide with temperature and solvent composition for the binary aqueous-ethanol solvent system. The equation coefficents given by Tang and coworkers, when substituted into the model equation, do not yield the authors' calculated mole fraction solubilities of cefpiramide.

A rapid thioacidolysis method for biomass lignin composition and tricin analysis (open access)

A rapid thioacidolysis method for biomass lignin composition and tricin analysis

This article developed a modified, rapid higher throughput thioacidolysis method to analyze both lignin monomeric composition and tricin content in the lignin polymer. The results demonstrate that the modified method can be used for rapid, high-throughput, and reliable lignin composition and tricin content analyses for screening transgenic plants for cell wall modifications or in large-scale genome-wide association studies (GWAS).

Upper lethal temperatures of Northern Bobwhite embryos and the thermal properties of their eggs (open access)

Upper lethal temperatures of Northern Bobwhite embryos and the thermal properties of their eggs

This article explores the upper lethal temperature for Bobwhite eggs. Results find that thermal tolerances of Northern Bobwhite embryos are high, indicating an adaptation to the naturally occurring temperature extremes in the Bobwhite's environment. However, the results also indicate that high temperatures could have plausibly contributed to the population decline observed in the Bobwhite's semi-arid range.

Artificially structured boundary for confinement of effectively unmagnetized cryogenic antimatter plasmas (open access)

Artificially structured boundary for confinement of effectively unmagnetized cryogenic antimatter plasmas

The article is from conference proceedings that discuss an artificially structured boundary (ABS) considered to consist of a spatially periodic arrangement of electrostatically plugged magnetic cusps. As envisioned, a non-neutral positron plasma could be confined by an ASB along its edge, and the space charge of the positron plasma would serve to confine an antiproton plasma. If the conditions of the two-species plasma are suitable, production of antihydrogen via three-body recombination for antimatter gravity studies may be possible.

NSFDEB-NERC: Collaborative Research: Wildlife corridors: do they work and who benefits? (open access)

NSFDEB-NERC: Collaborative Research: Wildlife corridors: do they work and who benefits?

Data management plan for the grant, "NSFDEB-NERC: Collaborative Research: Wildlife corridors: do they work and who benefits?" Research on the impact of wildlife corridors using genetics as the measure of effectiveness. The study will use 20 independent landscapes to quantify how corridor traits affect gene flow, and will use non-flying mammals as focal species because they are strongly affected by fragmentation. The research team hypothesizes (1) a strong non-linear decline in success (gene flow) with corridor length, reflecting the skewed distribution of dispersal distances within species; (2) success will drop steeply as corridor width falls below a threshold, with the threshold determined by species traits; and (3) species that are bigger, are habitat specialists, or have greater dispersal abilities (relative to brain size or reproductive rate) will benefit more from corridors. Testing these hypotheses will allow generalization to a wide range of mammal species not included in this project. It will use highly flexible Random Forest models to answer the overarching question: What landscape traits (e.g., corridor width, degree of human disturbance) and species traits (mobility, affinity to particular land cover types) are associated with effective corridors?

Multisite phosphorylation of a synthetic peptide derived from the carboxyl terminus of the ribosomal protein S6

Article synthesizing and testing the synthetic peptide AKRRRLSSLRASTSKSESSQK (56-21) which corresponds to the carboxyl-terminal 21 amino acids of human ribosomal protein S6 as a substrate for S6/H4 kinase purified from human placenta. The data suggests that multiple S6 kinases may be required to phosphorylate S6 at all five sites which are modified in vivo.

Instructional Models for Course-Based Research Experience (CRE) Teaching

This article presents a study that was done over a period of 3 years to explicate the instructional processes involved in teaching an undergraduate course-based research experience (CRE). The study presented here delineated a set of specific instructional practices used by active CRE instructors and modeled the relations between the use of these practices and specified outcomes. The resultant educational models should provide clarification of the ways in which the aims of CRE can be effectively achieved by instructors.

The metabolic cost of turning right side up in the Mediterranean spur-thighed tortoise (Testudo graeca)

Article examining the the metabolic cost of self-righting in the terrestrial Mediterranean spur-thighed tortoise using respirometry and kinematic video analysis and comparing this to the metabolic cost of locomotion at a moderate, easily sustainable speed. The results found that self-righting is, relatively, metabolically expensive and costs around two times the mass-specific power required to walk.
