In particular, TOUGH2Viewer allows to navigate through a 3D grid compatible with the iTOUGH2 data file format and see: (1) the thermodynamic variables and the material (namely, petrophysical properties) of each block; (2) maps of isovalues (2D) of all thermodynamic variables; (3) isosurfaces (3D) of all thermodynamic variables; (4) flows of mass and heat between blocks; (5) spatial profiles of thermodynamic variables, of a selected set of blocks, long a Cartesian directions; (6) time plot of thermodynamic variables of a selected block. All commands to manage a 3D visualization (zooming, pan, rotations) are CAD complying

An analysis on decentralized adaptive MAC protocols for Cognitive Radio networks

The scarcity of bandwidth in the radio spectrum has become more vital since the demand for more and more wireless applications has increased. Most of the spectrum bands have been allocated although many studies have shown that these bands are significantly underutilized most of the time. The problem of unavailability of spectrum and inefficiency in its utilization has been smartly addressed by the Cognitive Radio (CR) Technology which is an opportunistic network that senses the environment, observes the network changes, and then using knowledge gained from the prior interaction with the network, makes intelligent decisions by dynamically adapting their transmission characteristics. In this paper some of the decentralized adaptive MAC protocols for CR networks have been critically analyzed and a novel adaptive MAC protocol for CR networks, DNG-MAC which is decentralized and non-global in nature, has been proposed. The results show the DNG-MAC out performs other CR MAC protocols in terms of time and energy efficiency

Robert Nelson\u27s \u3cem\u3eA Room with a View\u3c/em\u3e: The Creation of a Contemporary Opera

My recent engagement as music director and conductor of Robert Nelson’s A Room with a View (1992, rev. 2004) has offered me the valuable opportunity to work on an opera side by side with its composer. The purpose of this dissertation is to reconstruct the various stages of the process of creation, interpretation, and performance of a contemporary opera, addressing aspects of the collaboration between the composer and the conductor. The methodology used in my research is based primarily on direct observation and interview. The investigation is conducted from the perspective of a “participant-observer,” due to my personal involvement in the project, as music director and conductor first, and then as interviewer and researcher. The document will be organized in three sections: - the first chapter will establish the context and specific features of my research, providing a scholarly background in relation to the study of the relationship between composer and conductor; - the second chapter will focus on the process of composition in all its stages. I have defined this as the “extended creative process” of A Room with a View; - the third chapter will discuss the Michigan State University production of the opera, considering several aspects of the artistic collaboration between Robert Nelson and me, as well as my involvement in the process as conductor. Through my research, I wish to provide useful insight into the crucial aspects of the composition and the production of new music. In addition, the project aims to offer a fresh contribution to the investigation of the relationship between composers and interpreters, and perhaps could provide some background reference for an interrogation about the current state and the future of American opera

Celecoxib for the prevention of nonmuscle invasive bladder cancer: Results from a matched control study

New targets and approaches are under investigation for the treatment of nonmuscle invasive bladder cancer (NMIBC). Preclinical data suggest cyclooxygenase-2 (COX-2) as a promising target. Celecoxib, a COX-2 selective inhibitor, inhibits tumor development and enhances survival, both in vitro and in vivo models of bladder cancer. Therefore, we conducted a pilot study of celecoxib to prevent recurrence in patients with intermediate risk NMIBC

A unified framework to catalogue and classify digital games based on interaction design and validation through clustering techniques

The digital games industry has grown exponentially due to the diversification of games and the increasing multiplicity of the user target base. The market explosion and the great variety make digital game cataloguing and classification challenging issues whose effectiveness can advance scientific research and address design, development and distribution. Firstly, the present study reviews previous cataloguing for video and serious games through systematic literature review and, joining together the findings from the literature review, develops a unified cataloguing model based on five definitions. This model can aid designers in tailoring their applications and contribute to disseminating game design knowledge in academic research. Then, a matrix that correlates design principles and the cataloguing model’s metadata is applied to the cataloguing model, obtaining a unified classification system. Together, they offer a comprehensive framework for understanding the multifaceted landscape of digital games, addressing the limitations of existing domain-specific approaches and providing a versatile tool for game designers. Research validation exploits a two-stage cluster analysis using agglomerative hierarchical and k-means clustering on the data extracted from a sample of digital games. The results show the framework's effectiveness in categorizing digital games without a clear-cut distinction between video and serious games. The system's application in real-world scenarios suggests its potential to guide game development. Future work will refine the proposal based on feedback from digital game designers, expanding the research scope to include a broader range of games

Endometrioma of the Abdominal Wall after Caesarean Section

Background:Endometrial cell implantation after abdominal surgery, mainly after caesarean section, may result in formation of endometrioma, which is usually described to be of various sizes, and adjacent to the surgical scar. Case:A 36-year old woman complaining of a mass of the abdominal wall with pain during the menstrual period, with a caesarean section 5 years earlier, presented a rounded tumour not contiguous to the Pfannenstiel’s laparotomy scar, of hard consistence, fixed and adherent to the deep abdominal wall structures, located on the left paramedian epigastric region. Magnetic Resonance imaging showed the nodule, involving the deep layers of the abdominal wall and the distance from the laparotomic scar. Surgical removal was performed with wide excision of the lesion, causing a large wall defect. After histological con-firmation (endometriosis) by frozen section, reconstruction of the abdominal wall required prolene mesh grafting. After twelve months the patient is healthy. Conclusion: When abdominal wall endometrioma is located distant from the scar, perhaps more frequently after Pfannenstiel’s laparotomic inci-sion, the differential diagnosis may be more difficult and MRI can help diffe-rentiating many of these lesions, and histological confirmation should be ob-tained intraoperatively, by frozen section, to allow an oncological resection if required

Mitochondrial caseinolytic protease p: A possible novel prognostic marker and therapeutic target in cancer

Caseinolytic protease P (ClpP) is a mitochondrial serine protease. In mammalian cells, the heterodimerization of ClpP and its AAA+ ClpX chaperone results in a complex called ClpXP, which has a relevant role in protein homeostasis and in maintaining mitochondrial functionality through the degradation of mitochondrial misfolded or damaged proteins. Recent studies demonstrate that ClpP is upregulated in primary and metastatic human tumors, supports tumor cell proliferation, and its overexpression desensitizes cells to cisplatin. Interestingly, small modulators of ClpP activity, both activators and inhibitors, are able to impair oxidative phosphorylation in cancer cells and to induce apoptosis. This review provides an overview of the role of ClpP in regulating mitochondrial functionality, in supporting tumor cell proliferation and cisplatin resistance; finally, we discuss whether this protease could represent a new prognostic marker and therapeutic target for the treatment of cancer

Exploring game design approaches through conversations with designers

This paper explores game designers' attitudes and praxis through a Grounded Theory analysis of data collected from interviews with 11 game design professionals. The aim of the research is to investigate and map possible shared approaches and strategies. The study presents a theoretical framework based on the core category “Balancing permanence and change”. Designers appear to build and maintain elements of stability, and contemporarily ensure the process’ flexibility and adaptability to possible constraints through collaborative approaches and iterative methods. The findings contribute to a deeper understanding of game design practices and provide a theoretical framework for interpreting designers' choices. Future research should assess the adaptability of the framework across game genres and cultural backgrounds of designers
