interrupting the processes which control ecosystem resources has dramatic impacts on the rangeland conditions. to protect ecosystems and landscape, it needs to understand the ecosystem processes which regulate the ecosystem resources. as main components of ecosystems, patches and inter-patches play important roles in energy and materials cascade. ecologically, functional parameters such as stab...

the present study was conducted on buffaloes that were non-cycling (heifers, n=32; lactating, n=13) or cycling (heifers, n=11; lactating, n=27) and in the buffaloes that conceived (heifers; n=11; lactating, n=23)or failed to conceive (heifers, n=32; lactating, n=17) subsequent to artificial insemination. plasma samples were analyzed for thyroid stimulating hormone, thyroid hormones, glucose, to...

background as the field of off-road cycling is usually remote areas with limited access to medical care, off-road cyclists are at higher risk of animal attacks and related injuries. case presentation we report two cases of dog attacks in off-road cycling and discuss the basic principles in prevention and management of such incidents. the cyclists received all 5-dose regimen of the rabies vaccin...

The aim of this study is to evaluate the color stability, translucency and hardness eight different composite resins, after thermal cycling immersion in beverages. Six light-cured dimethacrylate-based (Clearfil Majesty Esthetic, Clearfil Posterior, Grandio, Grandio Flow, Arabesk Top, Valux Plus), an ormocer (Admira) a silorane-based (Filtek Silorane) were tested study. Fifteen samples (8x2 mm) ...

Digital PCR is an exciting new field for molecular analysis, allowing unprecedented precision in the quantification of nucleic acids, as well as the fine discrimination of rare molecular events in complex samples. We here present a novel technology for digital PCR, Crystal Digital PCR™, which relies on the use of a single chip to partition samples into 2D droplet arrays, which are then subjecte...

A two-color magneto-optical trap (MOT) for trapping cesium (Cs) atoms is experimentally realized. This two-color MOT employs the radiation forces due to photon scattering from the Cs 6P(3/2) F' = 5 - 8S(1/2) F" = 4 excited-state transition, which replaced one pair of the three pairs of cooling/trapping laser beams operating on a single-photon red detuning to the Cs 6S(1/2) F = 4 - 6P(3/2) F' = ...

Fracture analysis of glass/epoxy composites under different thermal cycling conditions is considered. Temperature difference, stacking sequence, fiber volume fraction and number of thermal cycles are selected as the experimental design factors. The Taguchi method is implemented to design of the experiment and an apparatus is developed for automatic thermal cycling tests. The tensile tests are d...

Sensor networks are an example of a wireless network that needs each sensor to execute events in synchronization. This synchronization is necessary to coordinate power cycles to conserve energy and to ensure the proper functioning of sensors that measure time-sensitive events. Clock synchronization is important to the operation of each distributed wireless sensor network (WSN) because it sets a...
