The aim of the present work was to investigate how colour changes of foal meat can vary after thawing out in relation to the slaughtering age of the horses and to the post-thawing time. Eighteen Italian Heavy Draught Horse (IHDH) foals were used for the trial. They were subdivided in three groups according to their slaughtering age (6, 11 and 18 months). Two different surfaces were investigated...
نفوذپذیری از جمله مهمترین متغیرهای فیزیکی خاکها و دادهای بنیادین در کلیه مدلهای بارش و رواناب به منظور تعیین تلفات آب در سطح حوزههای آبخیز میباشد. اما اندازهگیری آن بسیار وقتگیر و پرهزینه بوده به همین دلیل برآورد مقادیر نفوذپذیری خاکها توسط مدلهای مختلف همواره از دغدغههای پژوهشگران بوده است. در این پژوهش به منظور تعیین بهترین معادله نفوذ در سطح حوضه آبخیز امامه، با استفاده از دستگاه ...
Sea Surface Salinity (SSS) is measured operationaly with Radiometers (e.g. SMOS) a resolution from 25 to 40 km. In this contribution, we theoretically evaluate Radar sensitivity SSS, especially focus on SAR (Synthetic Aperture Radar) due their intrinsic high-resolution imaging capabilities. This work focuses firstly the variations of dielectric properties seawater salinity at different frequenc...
The Advanced SCATterometer (ASCAT) is a real aperture, vertical polarisation, C-band radar designed primarily to provide global ocean winds operationally [Figa-Saldaña et al 2002, Klaes et al 2007]. The main application of these data is the assimilation into numerical weather prediction models, but its dense coverage makes the data also extremely useful for direct use by operational weather for...
Inherent in all empirical estimates of the geophysical model function (which relates the wind t o the normalized radar cross section, NRCS, of the ocean surface) is uncertainty caused by parameters not included in the empirical model. This can be thought of as variability in the NRCS for given wind conditions. W h e n the estimated variability is included in the max imum likelihood wind retriev...
BACKGROUND Microbiology reference laboratories are critical in the development of high-quality clinical and public health services. In Belgium, the reference laboratories performed their activities on a voluntary basis and lacked a legal status. METHODS Pathogens or groups of pathogens necessitating a national reference center (NRC) were prioritized based on diagnostic and epidemiologic relev...
Abstract The United States Department of Agriculture-Natural Resources Conservation Service (USDA-NRCS) works in a voluntary and collaborative manner with agricultural producers to solve natural resource issues on private lands. One the key steps formulating solution those is conservation planning process that identifies issues, highlights one or more practice standards can be used address allo...
The improved phase modulation method is used to numerically simulate a two-dimensional freak wave. While generating waves at specific positions, the spectral structure of target spectrum can also be maintained, and statistical characteristics wave sequences satisfied. numerical simulation process discussed in detail from perspective different spectra other parameters, priority applicability Joi...
We have investigated the effects of nonradiative recombination centers (NRCs) on the device performances of InGaN/GaN multi-quantum-well (MQW) light-emitting diodes (LEDs) incorporating low-temperature n-GaN (LT-GaN) underlying layers. Inserting an LT-GaN underlying layer prior to growing the MQWs is a successful means of separating the induced NRCs as a result of the presence of a growth inter...
