BRICS, a Multi-Centre “Legal Network”?  [PDF]
Lucia Scaffardi
Beijing Law Review (BLR) , 2014, DOI: 10.4236/blr.2014.52013
Abstract:

The paper analyzes the phenomenon of the BRICS group and its transformation into BRICs. From the first Summit, whose final declarations were mainly centered on economic, financial and commercial themes, the group attention has broadened its horizons, as to encompass health, agriculture, environment, international relations. The BRICS working method seems to suggest a new pattern of inter-state relations, based on peer-to-peer cooperation, experiences sharing and “soft” policy transfer. Given the difficult classification of this new “entity”, the author suggests considering it more as a network, where there is not a singular hegemony power, but where the relevance of the different countries varies according to the issue discussed in the Summit.

Protective Effects of Many Citrus Flavonoids on Cartilage Degradation Process  [PDF]
Lucia Crascì, Annamaria Panico
Journal of Biomaterials and Nanobiotechnology (JBNB) , 2013, DOI: 10.4236/jbnb.2013.43035
Abstract: The objective of this study was to investigate the effects of many citrus flavanones, such as neoeriocitrin, naringin and neohesperidin, in cartilage degradation. Degenerative joint disease involved degradation of joints, including articular cartilage and subchondral bone. When bone surfaces become less well protected by cartilage, bone may be exposed and damaged. The degradation cartilage is mediated by alteration of the balance between anabolic and catabolic processes, changes in proteolytic enzyme activity, mechanical disruption of the cartilage extracellular matrix (ECM), or a combination of these processes. We examine the capability of neoeriocitrin, naringin and neohesperidin, to inhibit metalloproteinase (MMP)-13, collagenase involved in degradation of cartilage matrix components. Also, we assay the flavonoids effect on reducing of Glycosaminoglycans (GAGs) release, and restore Nitric oxide (NO) levels in explant of human articular cartilage. Our results suggest that neoeriocitrin, naringin and neohesperidin are a potential therapeutic agent to protect cartilage tissue.
Simulating the Seismic Response of Concentrically Braced Frames Using Physical Theory Brace Models  [PDF]
Liang Chen, Lucia Tirca
Open Journal of Civil Engineering (OJCE) , 2013, DOI: 10.4236/ojce.2013.32A008
Abstract:

The aim of this paper is to assess the accuracy of brace models formulated in Drain 2DX and OpenSees by comparing the simulated results with those obtained from experimental tests. Both, Drain 2DX and OpenSees rely on the physical theory brace model. In this study, experimental tests conducted on the behaviour of structural hollow section braces subjected to symmetric and asymmetric quasi-static cyclic loading were selected for calibrating the numerical model. In addition, the predicted failure strain parameter resulted from a proposed empirical equation as a function of slenderness ratio, width-to-thickness ratio and steel properties was used to define the low-cycle fatigue material that was assigned to model braces in OpenSees. It is concluded that both Drain 2DX and OpenSees brace models give a good prediction in terms of maximum tensile and buckling force, as well as interstorey drift. However, in Drain 2DX, the brace model is not able to replicate the out-of-plan buckling and the braced frame model cannot provide an accurate response when the system experiences highly nonlinear demand. To emphasise the differences in performance between Drain 2DX and OpenSees, the behaviour of a 4-storey concentrically braced frame with zipper bracing configuration, located in Victoria, BC, was investigated.

Effects of Water Distribution Uniformity on Waxy Corn (Zea mays L.) Yield: Preliminary Results  [PDF]
Lucia Bortolini, Marco Martello
Journal of Water Resource and Protection (JWARP) , 2014, DOI: 10.4236/jwarp.2014.611098
Abstract:

To face climatic changes, the increase of frequency and severity of droughts, and economic development pressures, Water Management Institutions point at the necessity of water conserving. A sustainable demand-led approach is the most viable option, focusing on achieving more efficient irrigation practices instead of less sustainable expansion of supply. The aim of this work is to investigate on some aspects of the rational water management for the irrigation of corn in order to evaluate the actual possibility of introduction of drip irrigation systems on the Venetian Plain. Trials were carried out on a farm located in Isola della Scala (Verona, Italy) in an area of about 13 ha (12 ha with a drip irrigation system and 1 ha with a solid-set sprinkler system); the effects of the performance of the two systems on waxy corn yield were considered. In particular, water distribution uniformity, water use efficiency, and yield performance of irrigation systems were evaluated. DUlq and CU coefficients for distribution uniformity and IWUe and WUEb indexes for water use efficiency were calculated. To visualize and better analyze the distribution uniformity, the crop yield and the efficiency parameters, ArcGIS 10 (ESRI?) with IDW interpolation were used to create maps. First results show a good water uniformity distribution in the drip irrigation system but only with a careful and proper design of the entire system. As regards the water use efficiency, drip irrigation values are lower than those of sprinkler irrigation (-46% for IWUe and -25% for WUEb), probably due to different irrigation management and water volumes used: in fact, drip irrigation was scheduled every three days, while only supplemental operations were done for sprinkler irrigation. No statistical correlation was found between application rate and yield for both

Virginia Woolf’s History of Sexual Victimization: A Case Study in Light of Current Research  [PDF]
Lucia C. A. Williams
Psychology (PSYCH) , 2014, DOI: 10.4236/psych.2014.510128
Abstract:

Virginia Woolf’s history of sexual victimization is presented in a case study format, and reviewed in light of the present literature on the impact of child sexual abuse (CSA) to human development. The methodology to compose the case study involved reviewing the works of Woolf’s main biographers, the author’s memoirs, and the groundbreaking work of Louise DeSalvo, presenting data from Woolf’s diaries and letters, in which sexual abuse is disclosed. Woolf was sexually abused by her two older half-brothers. The abuse was extremely traumatic, and lasted several years. The various mental health symptoms that Woolf experienced are consistent with the literature of CSA. Woolf also presented some adequate coping skills by disclosing the CSA publicly, keeping records of her depressive episodes, and seeking help. Like many incest survivors, Woolf’s sexual abuse was minimized and questioned by biographers. In addition to Woolf’s enormous literary legacy, her knowledge of psychology was impressive. She was a feminist, as well as a visionary in exploring the effects of CSA before other incest survivors. Understanding her life influences is advantageous, not only to literary scholars but to most readers, and mainly clinicians and researchers are interested in the dynamics of sexual abuse.

Multicriteria Partial Cooperative Games  [PDF]
Graziano Pieri, Lucia Pusillo
Applied Mathematics (AM) , 2015, DOI: 10.4236/am.2015.612186
Abstract: In this paper, we study an approach to environmental topics, through multicriteria partial cooperative games. In general, not all players wish to cooperate to solve a common problem, so we consider a model where only some decision-makers cooperate. Starting from the transformation of a coalition game into a strategic one, we give a new concept of solution for partial cooperative models proving an existence theorem.
Attention deficit hyperactivity disorder secondary to lesion of the basal ganglia  [PDF]
Giovanni Mazzotta, Lucia Lucia Cirulli, Marco Sposato, Domenico Serino
World Journal of Neuroscience (WJNS) , 2012, DOI: 10.4236/wjns.2012.21007
Abstract: Attention Deficit Hyperactivity Disorder (ADHD) is a childhood onset autoregulation disorder characterized by attention deficit, hyperactivity and/or impul- siveness, which results in social and academic functional impairment. ADHD has a complex aetiology: along with genetic factors, anomalies in several cere-bral districts have been reported. We describe the case of a 9 year old boy with glucose-6-phosphate dehydrogenase deficiency in association with memory, behavioural and attentive disabilities. The patient’s clinical history is characterized by cerebral stroke at 3 years of age during a febrile episode, resulted in slight hemiparesis. Neuroimaging revealed a cystic lesion in the anterior portion of the right lenticular nucleus. Neuropsychological and psychiatric assess- ment evidenced alterations of executive functions. Diagnosis of ADHD secondary to lesion of the basal ganglia was made. We report the patient’s clinical profile in the light of current evidence pointing towards dysfunction of the basal ganglia as a crucial aetiological factor in memory and executive function impairment.
On the Individual Expectations of Non-Average Investors  [PDF]
Lucia Del Chicca, Gerhard Larcher
Journal of Mathematical Finance (JMF) , 2011, DOI: 10.4236/jmf.2011.13010
Abstract: An “average investor” is an investor who has “average risk aversion”, “average expectations” on the market returns and should invest in the “market portfolio” (this is, according to the Capital Asset Pricing Model, the best possible portfolio for such an investor). He is compared with a “non-average investor”. This - in our setting - is an investor who has the same “average risk aversion” but invests in other investment strategies, for example options. Such a “`non-average investor” must consequently have expectations on the market return that are different from the average: the “non-average expectations” In this paper we give an explicit formula for the “non-average expectations” in an arbitrary N-step model and for the extended concept in a Black- Scholes model, in the path-independent case and in the path-dependent case. Further we explicitly classify all the investment strategies for which the resulting “non-average expectations” show this mean aversion property. Various examples are given in the paper. These investigations were part of more general investigations initiated by an investment company carrying out certain subtle option trading strategies.
International Fragmentation of Production and Trade Volatility: An Analysis for the European Countries  [PDF]
Anna Maria Falzoni, Lucia Tajoli
Modern Economy (ME) , 2015, DOI: 10.4236/me.2015.63032
Abstract: In the last years, world exports have displayed very strong fluctuations, much higher than GDP fluctuations. Some recent works tried to understand the causes of these fluctuations, and in particular if these strong swings in world trade flows are related to the growing weight of intermediates in trade and to the phenomenon of international fragmentation of production (IFP) or international outsourcing. This is the issue addressed in this paper. We analyze the influence of international fragmentation of production and trade in intermediate goods on the fluctuations of trade flows for the EU countries. After assessing the relevance of international trade in intermediate goods at the sector level using indices computed from the input-output tables of the EU countries, we test whether a significant relation exists between the extent of international fragmentation of production measured by this proxy and the volatility of trade flows, and the possible implications of these results.
A MultiScale Gibbs-Helmholtz Constrained Cubic Equation of State
Angelo Lucia
Journal of Thermodynamics , 2010, DOI: 10.1155/2010/238365
Abstract: This paper presents a radically new approach to cubic equations of state (EOS) in which the Gibbs-Helmholtz equation is used to constrain the attraction or energy parameter, a. The resulting expressions for (,) for pure components and (,,) for mixtures contain internal energy departure functions and completely avoid the need to use empirical expressions like the Soave alpha function. Our approach also provides a novel and thermodynamically rigorous mixing rule for (,,). When the internal energy departure function is computed using Monte Carlo or molecular dynamics simulations as a function of current bulk phase conditions, the resulting EOS is a multiscale equation of state. The proposed new Gibbs-Helmholtz constrained (GHC) cubic equation of state is used to predict liquid densities at high pressure and validated using experimental data from literature. Numerical results clearly show that the GHC EOS provides fast and accurate computation of liquid densities at high pressure, which are needed in the determination of gas hydrate equilibria.
