Evaporation is a ubiquitous phenomenon in the natural environment and a dominant form of energy transfer in the Earth's climate. Engineered systems rarely, if ever, use evaporation as a source of energy, despite myriad examples of such adaptations in the biological world. Here, we report evaporation-driven engines that can power common tasks like locomotion and electricity generation. These eng...

the aim of the present study was to determination the prevalence of gastric ulcer in caspian miniature horse. the design field- laboratorial study on 23 caspian miniature horses. feed withdraw 12-16 hours before study and the owners or riders completed a form about housing, medication, age, sex, cell boold counts and the biochemical profile tests were carried out. endoscope performed through th...

nanoparticles of silver were treaeted as clinical trials in some broiler farms for its disinfecting characters in 4 broiler farms during growing period. the nanosilver were used orally and inhalatory in amount of 2 -4 ppm and 40 ppm respectively. some samples of breast muscle, femora muscle, heart, gizzard, liver, skin, spleen, lung, kidney and cloacal feces were collected randomly in slaughter...

ome of the highlights of the ongoing program within the Sensor Science Group of APL’s Milton S. Eisenhower Research and Technology Development Center to develop novel magnetometers are summarized. In particular, two approaches are described: a magnetostrictive device based on the deflection of a Terfenol-D coated single-crystal silicon cantilever and a Lorentz-force device based on a classical ...

In the absolute integrating-sphere method, the total luminous ̄ ux of a lamp inside an integrating sphere is determined by comparing it with a known ̄ ux introduced into the sphere from an external light source. As the measurement geometry of the lamps to be compared is different, the spatial non-uniformity of the sphere surface may affect the results. In order to evaluate this effect, the spat...

A series of miniature photometers has been developed for use as on-stream detectors in systems for liquid chromatography. All of the detectors feature dual-beam, dual-wavelength operation without mechanical or electrical switching of either wavelength or signal. The two types of detectors originally developed-ultraviolet (254 and 280 nm) and colorimetric (any two choices of visible wavelengths)...

This paper presents a method for determining the uniaxial tensile properties such as Young’s modulus, yield strength and the flow behaviour of a material in a virtually non-destructive manner. To achieve this, a new dumb-bell shaped miniature specimen has been designed. This helps in avoiding the removal of large size material samples from the in-service component for the evaluation of current ...

Blood samples were collected from 20 healthy miniature Caspian horses at 37 °C. Isolation of cryoglobulin was performed based on a standard method in present study. Harvested sera were kept at 4 °C for two hours and then examined for cryoglubolin. Four serum samples containing precipitate Suspicious of containing cryoglobulin were selected. Subsequently serum protein electrophoresis was perform...

Ultrasonography is a relatively easy, safe and non-invasive examination method which can be used in diagnosis of ocular disorders as complementary to routine ophthalmic examinations. As there has been no collated study undertaken on the normal measurements of ocular structures in Caspian miniature horse, obtaining these measurements could be a benchmark to diagnose some of the diseases and eye ...
