Physical Review
2013/10/8
Physical Review A (PRA) provides a dependable resource of worldwide developments in the rapidly evolving area of atomic, molecular, and optical physics and related fundamental concepts. The journal co...
In the late 1950's, Editor Sam Goudsmit decided to collect the Letters to the Editor of the Physical Review into a new standalone journal entitled Physical Review Letters (PRL). PRL featured short, im...
Fundamentals and Physics, such as: classification of effects, physical effects, measurement theory, modelling of sensors, measurement standards, measurement errors, units and constants, time and frequ...

Effects of Physical Form and Urea Treatment of Rice Straw on Rumen Fermentation, Microbial Protein Synthesis and Nutrient Digestibility in Dairy Steers
Rice Straw Urea Treatment Physical Forms Rumen Fermentation Microbial Protein Synthesis
2016/5/16
This study was designed to determine the effect of physical form and urea treatment of rice straw on rumen fermentation, microbial protein synthesis and nutrient digestibility. Four rumen-fistulated d...
Rumen Fermentation and Performance of Lactating Dairy Cows Affected by Physical Forms and Urea Treatment of Rice Straw
Rumen Fermentation Microbial Protein Synthesis Dairy Cows
2016/5/12
The aim of this study was to determine the effect of different physical forms and urea treatment of rice straw on feed intake, rumen fermentation, and milk production. Four, multiparous Holstein cross...
Effects of chemical and physical conditions on hatching success of Bythotrephes longimanus resting eggs
Effects of chemica Bythotrephes longimanus resting eggs
2014/4/2
Dormant eggs of zooplankton are considered to be tolerant of harsh environmental conditions, yet lethal
thresholds of exposure have rarely been determined. We describe 3 yr of dose–response experimen...
Physical responses of small temperate lakes to variation in dissolved organic carbon concentrations
dissolved organic carbon concentrations lakes
2014/4/2
We used a mechanistic physical model to examine the effect of variability in dissolved organic carbon (DOC)
concentrations on the physical properties of small temperate lakes. The model was validated...
物理方向国际著名学术期刊《Physical Review E》近期在线发表了交大致远学院2009级数理科学方向汤迎，及其合作者袁若石、马易安的最新研究成果“Dynamical behaviors determined by the Lyapunov function in competitive Lotka-Volterra systems”。汤迎为第一作者,负责了团队的主要工作。
The goal of this study was the determination of basic physical properties such as density, calorific value and rheological properties of liquid biofuels. Biofuels on the base of bioethanol and rapesee...
Light-likeness of Bordlines of Extremal Surfaces of Mixed Type in Physical Space-times
Light-likeness Bordlines Extremal Surfaces Mixed Type Physical Space-times
2018/4/19
In this paper, we prove the light-likeness of bordlines of smooth extremal surfaces of mixed type in general physical space-times, and for the case of the (1+2)-dimensional Minkowski space R1+2, we im...
PHYSICAL CONSTRAINTS ON THE SIZE AND SHAPE OF MICROALGAE
PHYSICAL CONSTRAINTS SIZE AND SHAPE
2015/11/12
Scaling laws provide a link between biology and physics. They provide a means
by which patterns in biology can be quantified and an explanation from physics can be
correlated with such patterns. I...
