Passive microwave remote sensing techniques can be used to monitor freeze/thaw at frozen soil surface. Researches found that the negative spectral gradient at 19GHz and 37GHz was a good criteria for decision of frozen soil[1]. At vegetated area, to make the algorithm simple, vegetation scattering were ignored, only their attenuation were considered, which were kept constant, regardless of veget...

the aim of the present study was to compare three reducing sugars (d-glucose, d-arabinose, d-mannose) with respect to the antioxidative activity characteristics of their caramelisation products (cps) prepared by monitoring uv-absorbance, browning intensity, ferric ion reducing capacity, fe2+ ion chelating activity as well as dpph radical scavenging activity. moreover, the effect of cps from d-g...

Ferti l i ty of semen frozen in a mechanica~ forced-vapor freezer was compared with that frozen in static nitrogen (N) vapor. Semen from 10 Holstein bulls was extended in milk-10% glycerol at 30 x 106 progressively motile spermatozoa/ml and packaged in .5-ml French straws. Straws were divided into three equal g roups ' bu l l l ' co l l ec t ion day -I and frozen in a mechanical freezer at full...

Software testing eff iciency is very important factor for all test organizations. By conducting a case study in data base environment. this paper is talking about how we can improve the test execution process by considering the factors like automation using standard framework, introducing risk based testing, parallel execution , modularization , avoiding code redundancy and thr ough proper test...

t has been shown that under certain conditions multidimensional signals can be recovered from one-level crossings (e.g. o crossings) However, the accuracy wlth which the locans of the one-level crossings need to .be specified is large ough to limit its applicabllity in practical situations. To ercome this problem, we derive two sampling strategies for construction of multidlmensional signals fr...

Land application of manure containing antimicrobials results in the dispersion of the antimicrobials in agro-ecosystems. Dissipation of excreted antimicrobials in seasonally frozen agricultural soils has not been fully characterized under field conditions. This study investigated the field dissipation kinetics of chlortetracycline, sulfamethazine, and tylosin over a 10-mo period after fall appl...

background and objective: to determine the diagnostic accuracy and pitfalls of frozen section in ovarian tumors in one of the largest university affiliated gynecologic oncology centers in tehran, and determine the cause of discrepancies. materials and methods: we retrospectively analyzed the results of frozen section and permanent diagnoses of ovarian masses by reviewing the reports in the dep...

The multi-index matching problem generalizes the well known matching problem by going from pairs to d-uplets. We use the cavity method from statistical physics to analyse its properties when the costs of the d-uplets are random. At low temperatures we find for d ≥ 3 a frozen glassy phase with vanishing entropy. We also investigate some properties of small samples by enumerating the lowest cost ...

frozen section and touch imprint cytology are important diagnostic procedures for surgeons during operation and must be accurate if the patient is to receive maximum benefit. to assess the accuracy of intraoperative pathologic consultation including frozen section and touch imprint cytology during a five year period (1995- 2000), a retrospective survey of 1000 consecutive cases of frozen sectio...
