In this study, a odor concentration estimation model in the grow to finish swine pen was derived using principal component analysis and multiple regression models. 14 kinds of compounds were used. Prior statistical analysis, missing value (less than MDL)for each imputed with MDL/2, unit log-transformed follow normal distribution. The three components extracted through explained for 77.03% initi...

نانوذرات مغناطیسی فریت نیکل- منگنز- مس عمدتأ در دارورسانی مغناطیسی، محیط های مغناطیسی ضبط داده ها، حسگرهای گازی، مدارهای فرکانس بالا و ذخیره اطلاعات و ... کاربرد فراوانی دارند. در این پایان نامه نانوذرات مغناطیسی فریت نیکل - منگنز - مس با درصدهای متفاوت جانشانی مس به جای منگنز به روش هم رسوبی شیمیایی تهیه شدند و خواص ساختاری، مغناطیسی و الکتریکی آنها مورد مطالعه و بررسی قرارگرفت. برای مشخصه یاب...
Shlomo Morant Self stabilizing protocols for distributed systems in the shared memory model are defined and studied. The protocols presented here improve upon previous protocols in two ways: Ftrst, it is assumed that the only atomic ol>erations are either read <r write ~ the shared memory. Second, our protocols work for dynamic networks, in which the topology of lhe network may change during th...
In both forest and agricultural soils, plant derived cuticular materials can constitute a significant part of soil organic matter. In this study, the sorption of nonpolar (naphthalene and phenanthrene) and polar (phenol and 1-naphthol) aromatic organic pollutants to aliphatic-rich cuticularfractions of green pepper (Capsicum annuum) (i.e., bulk (PC1), dewaxed (PC2), nonsaponifiable (PC3), nonsa...
Parent-of-origin-dependent (epi)genetic factors are important determinants of prenatal development that program adult phenotype. However, data on magnitude and specificity of maternal and paternal genome effects on fetal bone are lacking. We used an outbred bovine model to dissect and quantify effects of parental genomes, fetal sex, and nongenetic maternal effects on the fetal skeleton and anal...
Understanding distribution of soil properties at the field scale is important for improving agricultural management practices and for assessing the effects of agriculture on environmental quality. Spatial variability within soil occurs naturally due to pedogenic factors as well as land use and management strategies. The variability of soil properties within fields is often described by classica...
This article aims to investigate the 3D morpho-sedimentary dynamics of two gravel beaches in relation hydrodynamic forcing, using a multi-sensor approach. Study sites, namely Etretat and Hautot-sur-Mer, are both located Normandy, France. Thus, they face similar wave conditions English channel's eastern side, with megatidal ranges channelized orientations. However, differ size (D50 = 5.2 cm; D50...

Nonlinear principal component analysis (NLPCA) is a descriptive dimension reduction method that examines the relationships between variables and displays results numerically visually in multivariate datasets have linear or nonlinear relationship them. In this study, it was aimed to present basic explanatory information about components emphasize its usability by performing application. data obt...
