Impact of Poultry Manure-Derived Biochar and Bio-Fertilizer Application to Boost Production of Black Cumin Plants (Nigella sativa L.) Grown on Sandy Loam Soil
No full textBiochar derived from poultry manure increases nutrient availability and promotes plant growth. This study investigated the effect of biochar with mycorrhizal and/or plant growthpromoting rhizobacteria on soil fertility, chemical properties, oil, and seed yield of Black Cumin (Nigella sativa L.) plants. A split-plot design with three replicates was employed, with biochar derived from poultry litter (BC) applied at rates of 0, 5, and 10 t ha−1, with beneficial microbes such as arbuscular mycorrhizal fungi (AMF) and plant growth-promoting rhizobacteria (PGPR) affecting the growth of Black Cumin plants, and some soil properties, such as pH, electrical conductivity (EC), soil organic matter (SOM) and fertility index (FI), showing significant differences (p ≤ 0.05) among biochar and/or bio-fertilizer treatments. All biochar treatments with or without bio-fertilizers significantly increased pH, EC, OM and FI in comparison to the control treatment. The results demonstrated that applying biochar at the highest rate (10 t ha−1) increased fresh and dry capsule weights by 94.51% and 63.34%, respectively, compared to the control treatment (C). These values were significantly increased by 53.05 and 18.37%, compared to untreated plants when combined with AMF and PGPR. Furthermore, when biochar was applied in conjunction with both AMF and PGPR, fresh and dry capsule weights saw significant increases of 208.84% and 91.18%, respectively, compared to the untreated control treatment. The interaction between biochar, AMF, and PGPR
significantly improved plant growth, yield, soil properties, and the fixed and volatile oil content of Black Cumin. These findings suggest that the combined application of biochar, AMF, and PGPR enhances nutrient availability and uptake, leading to improved growth and higher yields in Black Cumin plants, resulting in increased yield productio
Modelling correlated consumers’ preferences
No full textThe CUB model is a mixture distribution recently proposed in literature for modelling ordinal data. The CUB parameters may be related to explanatory variables describing the raters or the object of evaluation. Although various methodological aspects of this class of models have been investigated, the problem of multivariate ordinal data representation is still open. In this article the Plackett distribution is used in order to construct a bivariate distribution from CUB margins. Furthermore, the model is extended so that the effect of rater characteristics on their stated preferences is included
L’islam in Italia e le carceri
No full textEsiste un islam europeo? Larga parte dell’opinione pubblica in Europa ha una percezione negativa dei musulmani, dovuta alla paura per gli attacchi terroristici e al racconto allarmista dell’immigrazione islamica, considerati così due fenomeni correlati. Tutto ciò genera forme di islamofobia con ricadute dagli alti costi sociali, sia per quel che riguarda il processo di integrazione sia – paradossalmente – per la stessa lotta alla radicalizzazione. L’Europa ha la storia e le risorse per produrre modelli di inclusione capaci di disinnescare questa spirale di conflitti sociali interconnessi. Le voci autorevoli raccolte nel volume mostrano la realtà poco conosciuta dei “musulmani d’Europa” e indicano la strada di un’integrazione possibile
Beating cancer in multiple ways using nanogold
No full textGold nanoparticles possess a unique combination of properties which allow them to act as highly multifunctional anti-cancer agents (X. H. Huang, P. K. Jain, I. H. El-Sayed and M. A. El-Sayed, Nanomedicine, 2007, 2, 681–693; P. Ghosh, G. Han, M. De, C. K. Kim and V. M. Rotello, Adv. Drug Delivery Rev., 2008, 60, 1307–1315; S. Lal, S. E. Clare and N. J. Halas, Acc. Chem.

Not only can they be used as targeted contrast agents for photothermal cancer therapy, they can serve as scaffolds for increasingly potent cancer drug delivery, as transfection agents for selective gene therapy, and as intrinsic antineoplastic agents. This tutorial review will highlight some of the many forms and recent applications of these gold nanoparticle conjugates by our lab and others, as well as their rational design and physiologic interactions. © 2011 The Royal Society of Chemistry
Computational design of optimal discrete-time output feedback controllers
No full textAbstract This paper considers the problem of designing a stabilizing static output feedback controller of linear discrete-time systems that minimizes certain quadratic performance index. A trust-region method is developed to solve an equivalent optimization problem of this optimal control problem. In addition, a first-order method is introduced to compute suboptimal stabilizing output feedback controllers that are used to initiate the trust-region method. Finally some numerical results that illustrate the performance of the proposed methods are given
