title: Humoral and Secretory Immunoglobulins of the Sheepshead, Archosargus probatocephalus, A Marine Teleost
Creators: name: Lobb, Craig J.
Publisher: name: Utah State University
Year: 1980

description: The sheepshead has two readily isolatable humoral immunoglobulins, a 16S tetrameric form and a 6S monomeric form. The 16S tetrameric form is composed of two subpopulations, one being a disulfide linked form (~700,000 daltons) and the other a noncovalently linked population of predominantly disulfide linked dimers (~350,000 daltons). The 6s immunoglobulin (~140,000 daltons) is composed of two noncovalently linked units (~70,000 daltons) each having one heavy and one light chain. The 6S immunoglobulin is antigenically deficient to the 16S immunoglobulin, this deficiency may be due to the heavy chain of the 6s protein lacking a~25,000 dalton segment present in the heavy chain of the 16S molecule.
Cutaneous mucus and bile also contain immunoglobulins. The mucus contains three proteins that can be considered immunoglobulins: a 6S form which is antigenically indistinguishable from the serum 6S immunoglobulin: a ~700,000 dalton form which does not have a "dimeric" subpopulation as observed with the serum 16S protein; and a dimeric form of ~350,000 daltons. The dimeric form may have a secretory piece since the reduced mucus dimeric protein shows an additional polypeptide chain at ~95,000 daltons. All of the cutaneous mucus high molecular weight immunoglobulins have heavy and light chains identical to the serum high molecular weight immunoglobulins (~70,000 and ~25,000 daltons).
Bile immunoglobulin is dimeric and composed of two noncovalently linked monomers of ~l60,000 daltons. The bile heavy chains are ~55,000 daltons; the light chains are ~25,000 daltons. The bile immunoglobulin does not appear to be a different class of protein from that of the serum or mucus immunoglobulins.
In vivo administration of radiolabeled 16S and 6S serum immunoglobulins indicates that the 6S protein is not a degradation product of the 16S form. The half lives of the 16S and 6s forms are both ~16 days.
Furthermore, the secretory immunoglobulins of the bile and mucus are not due to simple transudation or active transport of the predominant serum immunoglobulins. This result suggests that the secretory immunoglobulins of the sheepshead may be locally synthesized.
Elastic energy loss and longitudinal straggling of a hard jet

description: The elastic energy loss encountered by jets produced in deep-inelastic scattering (DIS) off a large nucleus is studied in the collinear limit. In close analogy to the case of (non-radiative) transverse momentum broadening, which is dependent on the medium transport coefficient $\hat{q}$, a class of medium enhanced higher twist operators which contribute to the non-radiative loss of the forward light-cone momentum of the jet ($q^-$) are identified and the leading correction in the limit of asymptotically high $q^-$ is isolated. Based on these operator products, a new transport coefficient $\hat{e}$ is motivated which quantifies the energy loss per unit length encountered by the hard jet. These operator products are then computed, explicitly, in the case of a similar hard jet traversing a deconfined quark-gluon-plasma (QGP) in the hard-thermal-loop (HTL) approximation. This is followed by an evaluation of sub-leading contributions which are suppressed by the light-cone momentum $q^-$, which yields the longitudinal "straggling" i.e., a slight change in light cone momentum due to the Brownian propagation through a medium with a fluctuating color field.

description: Abstract

The development of the Center Point of Indonesia area is a large infrastructure project that aims to increase economic growth and community welfare in Eastern Indonesia. Like many other large-scale projects, the development of Center Point of Indonesia has the potential to cause significant impacts on the environment, including changes in air, water, and soil quality, as well as reduced biodiversity. Given the importance of maintaining a balance between development and environmental sustainability, this research is urgently needed. This research is important to understand and manage the environmental impacts of the Center Point development in Indonesia. These impacts, if not handled properly, can cause irreparable ecological damage, disrupt local ecosystems, and affect the welfare of local communities. Comprehensive data and analysis will help stakeholders make better decisions regarding the development of future infrastructure projects. This study aims to assess the impact of the development of the CPI Area on environmental quality (air, water, soil, and biodiversity). Analyze the socio-economic changes in the surrounding community as a result of this development.
Ruolo delle cellule staminali mesenchimali in modelli cellulari e animali di nefropatia
Creators: name: Magnasco, Alberto <1964>
Publisher: name: Alma Mater Studiorum - Università di Bologna
Year: 2008
Subjects: MED/14 Nefrologia

description: Background. Mesenchymal stem cells (MSC) may be of value in
regeneration of renal tissue after damage, however lack of biological knowledge and
variability of results in animal models limit their utilization.
Methods. We studied the effects of MSC on podocytes ‘in vitro’ and ‘in vivo’
utilizing adriamycin (ADR) as a model of renal toxicity. The ‘in vivo’ experimental
approach was carried out in male Sprague Dawley rats (overall 60 animals) treated
with different ADR schemes to induce acute and chronic nephrosis. MSC were
given a) concomitantly to ADR in tail vein or b) in aorta and c) in tail vein 60 days
after ADR. Homing was assessed with PKH26-MSC.
Results. MSC rescued podocytes from apoptosis induced by ADR ‘in vitro’. The
maximal effect (80% rescue) was obtained with MSC/Podocytes co-culture ratio of
1:1 for 72 hours. All rats treated with ADR developed nephrosis. In no case MSC
modified the clinical parameters (i.e. proteinuria, serum creatinine, lipids) but
protected the kidney from severe glomerulosclerosis when given concomitantly to
ADR. Rats given MSC 60 days after ADR developed the same severe renal damage.
Only few MSC were found in renal tubule-interstitial areas after 1-24 hours from
injection and no MSC was detected in glomeruli.
Conclusions. MSC reduced apoptosis of podocytes treated with ADR ‘in vitro’.
Early and repeated MSC infusion blunted glomerular damage in chronic ADR
nephropathy. MSC did not modify proteinuria and progression to renal failure, that
implies lack of regenerative potential in this model.

description: Many astrochemical models of observed CO isotopologue line emission, earlier considered a good proxy measure of H$_2$ and hence disk gas mass, favor large deviations in the carbon and oxygen gas phase abundances and argue that severe gas phase CO depletion makes it a poor mass tracer. Here, we show that C$^{18}$O line emission is an effective measure of the gas mass, and despite its complex chemistry, a possibly better tracer than HD. Our models are able to reproduce C$^{18}$O emission from recent ALMA surveys and the TW Hya disk to within a factor of $\sim 2-3$ using carbon and oxygen abundances characteristic of the interstellar medium (C/H$=1.4 \times 10^{-4}$; O/H$=3.2\times 10^{-4}$) without having to invoke unusual chemical processing. Our gas and dust disk structure calculations considering hydrostatic pressure equilibrium and our treatment of the CO conversion on grains are primarily responsible for the very different conclusions on disk masses and CO depletion. As did previous studies, we find that a gas phase C/O of $\sim 1-2$ can explain observed hydrocarbon emission from the TW Hya disk; but significantly, we find that CO isotopologue emission is only marginally affected by the C/O ratio. We therefore conclude that C$^{18}$O emission provides estimates of disk masses that are uncertain only to within a factor of a few, and describe a simplified modeling procedure to obtain gas disk masses from C$^{18}$O emission lines.

description: A modern management of crop protection should be based on integrated control programmes, including the use of environmentally safe products. Antagonistic/beneficial bacteria and resistance inducers may have a great potential in the prophylaxis of diseases caused by common and quarantine pathogens. This work was carried out to confirm the ability of the known strain IPV-BO G19 (Pseudomonas fluorescens) against fire blight (Erwinia amylovora), as well as to evaluate their efficacy against southern bacterial wilt of tomato (Ralstonia solanacearum) and grapevine crown gall (Agrobacterium vitis). A virulent strain of R. solanacearum race 3 was inhibited by the antagonist on plate. When the pathogen was inoculated 48 h after their application to the root apparatus of tomato plants grown in a climatic chamber, bacterial wilt progression rate was clearly reduced. Moreover the defence response evoked by IPV-BO G19 was studied in tomato plants by monitoring the transcription of genes codifying for three PRs as PR-1a, PR-4, PR-5 and for an intracellular chitinase using multiplex RT-PCR and Real Time RT-PCR. In two field trials during 2005 and 2006, the strain IPV-BO G19 was compared with biofungicides and some abiotic elicitors to protect actively growing shoots of pear scions against fire blight. In both trials, IPV-BO G19 plus Na-alginate gave a high level of protection, three weeks after wound inoculation with E. amylovora. In pear leaf tissues treated with the antagonistic strain IPV-BO G19, catalase, superoxyde dismutase and peroxidise activity was evaluated as markers of induced resistance. The IPV-BO G19 strain was compared with other bioagents and resistance inducers to prevent grapevine crown gall under glasshouse and vineyard conditions.

description: Abstract

Automobiles and other vehicles have become very essential in modern-day life. As the number of vehicles is increasing day by day, the speed at which they move is also increasing, necessitating the construction of speed bumps/dumps. Here, an attempt is made to harvest the kinetic energy of these moving vehicles as they cross the speed bumps, using a piezoelectric transducer, and then use it to illuminate the streetlight near the speed bump. The construction of these electricity-producing, energy-harvesting systems can be efficiently integrated with the speed dumps themselves such that they will not cause any obstruction or discomfort to vehicles and pedestrians. It is envisaged that these kinds of systems will pave the way for the installation of many sustainable energy solutions, especially in poor and remote locations where the laying of the grid for such small power requirements is not economical. This paper aims to analyze the feasibility and potential benefits of implementing electricity generation from speed bumps as a sustainable energy solution. The study will examine the technological and economic aspects of this innovative approach. It aims to analyze the feasibility and potential impact of implementing this technology in urban environments.

title: The Isolation and Characterization of a Novel Iron Protein from Desulfovibrio gigas
Creators: name: Smith, Alan Kay
Publisher: name: Utah State University
Year: 1982

description: The isolation, purification, and partial characterization of a novel iron-containing protein from the sulfate-reducing anaerobic bacterium, Desulfovibrio gigas, is described. The highly insoluble protein was isolated from the cell debris following osmotic shock of the bacteria. The insoluble fraction consistently contained about 90% of the cell-associated iron. This protein was treated with acid, chelating agents, detergents and proteases in order to study their effect on the iron solubility. The results of elemental analysis of a crude protein preparation were 5.3% iron, 2.9% sulfur and 11 .9% nitrogen. An independent colorimetric iron analysis showed 6.4% iron. The iron could be dissociated from the protein by treatment with 5% sodium dodecyl sulfate. The iron-free protein was purified by a combination of organic extraction and DEAE-cellulose chromatography. The purified protein showed only one major band, MW 14,000, by SDS polyacrylamide gel electrophoresis. The protein could be reconstituted upon treatment with an appropriate mixture of FeS and B-mercaptoethanol. The reconstituted protein had the same physical and chemical properties as the native protein. The amino acid composition was not unusual except for the high isoleucine content. The amino acid composition was similar to that of a number of membrane proteins.
Growth and iron assimilation in D. gigas were studied and the form of iron present in the medium were also examined. The intracellular distribution of iron and sulfur assimilated from the medium was determined. The presence of an iron chelating compound was also briefly examined.
Some interesting observations and experiments dealing with colored iron complexes and their characteristics are included. An unusual basic component tentatively identified as cadaverine is also discussed briefly.

description: This dissertation examined a combined approach to teach novel vocabulary in English and Spanish for dual language learners prior to an English storybook read- aloud in a preschool setting. The 6-week intervention study was conducted in a Head Start program in the U. S. Mountain West with 60 dual-language preschoolers randomly assigned to small groups to receive the vocabulary intervention, using images and word definitions from researcher-trained teachers, teacher assistants or parent volunteers.
The experimental design included pre- and posttest assessments of target and general receptive vocabulary in English and Spanish, as well as language exposure, instructional quality, and fidelity of treatment. Teachers demonstrated a high level of fidelity in the preteaching of vocabulary in small groups. A multiple regression analyses and t-test comparisons indicate that preschoolers made comparable gains in breadth and depth of target vocabulary in Spanish and English, with higher definitional gains of vocabulary outcomes among those receiving vocabulary instruction in Spanish. For example, the Spanish-language group provided more diverse and robust definitions for target words. The results suggest that an explicit, target vocabulary intervention can improve Spanish-speaking preschoolers’ academic vocabulary in Spanish and English. Use of the home language seemingly supported word learning in both Spanish and English and appeared to increase linguistic awareness more than those receiving only English. The brief, small-group, vocabulary instruction was relatively easy to implement and shows promise as a curricular component available to Head Start programs. Implications for instruction and future research are included.

description: Abstract

The rise of Information and Communication Technologies (ICT) has transformed the 21st century into a global village, enhancing government and public service delivery by making information more accessible and cost-effective. However, the proliferation of ICT in government also brings the threat of cybercrime, which poses significant challenges to e-government services and national security, particularly in Nigeria. Although the Internet facilitates free access to information, it is also exploited by cybercriminals, adversely affecting public services and cybersecurity. This study aims to address strategies to mitigate the adverse impacts of cybercrime on cybersecurity within the context of e-government in Nigeria. Grounded in the crime opportunity theory, the research adopts a quantitative approach with a survey design. Primary data were collected from 381 out of 1,190 government employees in Kaduna State using a structured questionnaire and Simple Random Sampling Technique. Data analysis used Multiple Regression with the Statistical Package for the Social Sciences (SPSS) version 26.0 to interpret the collected data and derive meaningful insights. The findings indicate a significant positive relationship between cybersecurity and factors such as capacity building, enhanced funding and resources, modernization of IT systems, and public awareness campaigns. However, the relationship between an established incident response and recovery plan and cybersecurity was found to be positive but not significant. Based on these results, the study recommends continuous staff training, recruitment of skilled personnel, collaboration with cybersecurity experts, and stricter sanctions for cybercriminals. Additionally, it advocates for comprehensive cybercrime legislation to combat online threats effectively.

description: We present a unified variational treatment of the electric quadrupole (E2) matrix elements, Einstein coefficients, and line strengths for general open-shell diatomic molecules in the general purpose diatomic code \Duo. Transformation relations between the Cartesian representation (typically used in electronic structure calculations) to the tensorial representation (required for spectroscopic applications) of the electric quadrupole moment components are derived. The implementation has been validated against accurate theoretical calculations and experimental measurements of quadrupole intensities of $^1\text{H}_2$ available in the literature. We also present accurate electronic structure calculations of the electric quadrupole moment functions for the $X^1Σ^+$ electronic states of $\text{CO}$ and $\text{HF}$ at the CCSD(T) and MRCI levels of theory, respectively, as well for the $a^1Δ_g$ -- $b^1Σ_g^+$ quadrupole transition moment of $\text{O}_2$ with MRCI level of theory. Accurate infrared E2 line lists for $^{12}\text{C}^{16}\text{O}$ and $^1\text{H}^{19}\text{F}$ are provided. A demonstration of spectroscopic applications is presented by simulating E2 spectra for $^{12}\text{C}^{16}\text{O}$, $\text{H}^{19}\text{F}$ and $^{16}\text{O}_2$ (Noxon $a^1Δ_g$ -- $b^1Σ_g^+$ band).

Quantum Algorithms Using the Curvelet Transform

description: The curvelet transform is a directional wavelet transform over R^n, which is used to analyze functions that have singularities along smooth surfaces (Candes and Donoho, 2002). I demonstrate how this can lead to new quantum algorithms. I give an efficient implementation of a quantum curvelet transform, together with two applications: a single-shot measurement procedure for approximately finding the center of a ball in R^n, given a quantum-sample over the ball; and, a quantum algorithm for finding the center of a radial function over R^n, given oracle access to the function. I conjecture that these algorithms succeed with constant probability, using one quantum-sample and O(1) oracle queries, respectively, independent of the dimension n -- this can be interpreted as a quantum speed-up. To support this conjecture, I prove rigorous bounds on the distribution of probability mass for the continuous curvelet transform. This shows that the above algorithms work in an idealized "continuous" model.

description: Remote sensing (RS) techniques have evolved into an important instrument to investigate forest function. New methods based on the remote detection of leaf biochemistry and photosynthesis are being developed and applied in pilot studies from airborne and satellite platforms (PRI, solar-induced fluorescence; N and chlorophyll content).
Non-destructive monitoring methods, a direct application of RS studies, are also proving increasingly attractive for the determination of stress conditions or nutrient deficiencies not only in research but also in agronomy, horticulture and urban forestry (proximal RS).
In this work I will focus on some novel techniques recently developed for the estimation of photochemistry and photosynthetic rates based (i) on the proximal measurement of steady-state chlorophyll fluorescence yield, or (ii) the remote sensing of changes in hyperspectral leaf reflectance, associated to xanthophyll de-epoxydation and energy partitioning, which is closely coupled to leaf photochemistry and photosynthesis. I will also present and describe a mathematical model of leaf steady-state fluorescence and photosynthesis recently developed in our group. Two different species were used in the experiments:  Arbutus unedo, a schlerophyllous Mediterranean species, and Populus euroamericana, a broad leaf deciduous tree widely used in plantation forestry. 
Results show that ambient fluorescence could provide a useful tool for testing photosynthetic processes from a distance. These results confirm also the photosynthetic reflectance index (PRI) as an efficient remote sensing reflectance index estimating short-term changes in photochemical efficiency as well as long-term changes in leaf biochemistry.
The study also demonstrated that RS techniques could provide a fast and reliable method to estimate photosynthetic pigment content and total nitrogen, beside assessing the state of photochemical process in our plants’ leaves in the field. This could have important practical applications for the management of plant cultivation systems, for the estimation of the nutrient requirements of our plants for optimal growth.
title: Why Do You Go to University? Outcomes Associated With Student Beliefs About the Purposes of a University Education
Creators: name: Colver, Mitchell C.
Publisher: name: Utah State University
Year: 2018

description: Students enter the realm of higher education with a wide variety of beliefs about the purposes of attending university, which often relate to or reveal their various motivations for pursuing a post-secondary education. Research demonstrates that some student motivations align more fully with intrinsic factors, such as the love of learning or quest for excellence, while other student motivations align with extrinsic factors, such as vocational preparedness and monetary incentives (Vallerand et al., 1989). Using a Bourdieusienne lens, this study sought to place these student motivations in the larger sociocultural context and argue for greater opportunities for democratic equity in post-secondary environments. Relying on Self-Determination Theory, the study investigated the relationship between student academic motivations and longitudinal academic performance at a four-year, research oriented university in the United States. More importantly, the study sought to determine if institutional interventions, specifically incoming student orientation and a first-year experience (FYE) course, were valuable in helping align student motivations with the central values of higher education. Using the Academic Motivation Scale for College (AMS-C) across two years, the study employed a Latent Profile Analysis (LPA) and Latent Transition Analysis (LTA) to extract several profiles or “types” of student motivation and examined developmental variability of these profiles across time. Students who shifted from a more controlled to a more autonomous motivational profile in connection with institutional intervention demonstrated the highest levels of first-year academic performance and retention. However, these results diminished during the second academic year. Implications for practice suggest the importance of providing students with a values-based intervention to enhance autonomy-oriented academic motivation and to do so in a manner that sustains this enhancement throughout the academic career.
The relationship of metals and soil organic components with particular reference to copper
Creators: name: Cross, Christine Hazel
Publisher: name: University of British Columbia
Year: 2010

description: An ap horizon of a soil collected from a highly mineralized area was fractionated into five organic and mineral components and the distribution of cu, zn, pb, ca and mg within these components was determined. Zn and ca were removed to a considerable degree in the 0.1n hcl extract. Of the five metals, cu and pb were the only ones present which combined with organic matter to any considerable degree. Of the five organic and mineral components, fulvic acid was shown to display the greatest complexing activity. Although gel filtration has been used extensively in the field of biochemistry, it was shown that the metal retaining properties of the various sephadex and agar gels used caused the technique to be unsuitable for the separation of naturally occurring metal-organic complexes. In addition the distribution of fe, cu and zn within the profiles of two soils from less mineralized areas was determined but the low levels of metal found did not permit a direct investigation of their metal-organic complexes. In order to study in detail metal-0rganic matter reactions, humic acids were extracted from several of the above soils. Functional group analysis coupled with elemental analysis for c, h, N and 0 in these humic acids revealed that a large percentage of the oxygen was unaccounted for in carboxylic acid and phenolic Hydoxylic groups, thus indicating the presence of other oxygen containing groups. Infrared spectra showed decreases in the amount of aliphatic material present with increasing maturity of the humic acids and also gave supporting evidence of complex formation upon the addition of cu. The humic acids were used in a series of incremental potentio- Metric titration experiments which monitored the pattern of proton release in response to copper additions at a series of ph levels. The resultant curves for humic acids of various origins were alike in their general shapes but displayed differences in detail which were especially marked between the juvenile and the more mature acids. Whereas in all cases of humic acids derived from mineral soils the proton release increased with ph, the peat humic acid displayed a greater proton release at ph 5.0 than at ph 6.0. The shapes of the curves obtained with humic acids were compared with those obtained in similar experiments from a series of model compounds of known chemical composition and were found to approximate most closely the patterns derived from salicylic acid and phthalic acid. This provides additional evidence for the hypothesis that salicylic and phthalic acid-like functional groups play a significant role in the formation of metal-organic complexes in soils.
title: Electron Flow and Management in Living Systems: Advancing Understanding of Electron Transfer to Nitrogenase

description: Nitrogen is a critical nutrient for growth and reproduction in living organisms. Although the Earth’s atmosphere is composed of ~80% nitrogen gas (N2), it is inaccessible to most living organisms in that form. Biological nitrogen fixation, however, can be performed by microbes that harbor the enzyme nitrogenase. This enzyme converts N2 into bioavailable ammonia (NH3) and accounts for at least half of the “fixed”nitrogen on the planet. The other major contributor to ammonia production is the industrial Haber-Bosch process. While the Haber-Bosch process has made significant advances in sustaining the global food supply through the generation of fertilizer, it requires high temperature and pressure and fossil fuels. This makes nitrogenase an ideal system for study, as it is capable of performing this challenging chemistry under ambient conditions and without fossil fuels.
Nitrogenase requires energy and electrons to convert N2into NH3. The work presented here examined how the enzyme receives electrons to perform the reaction. It was discovered that some microbes employ a novel mechanism that adjusts the energy state of the electrons so that nitrogenase can accept them. Further, the slowest step that takes place in nitrogenase once the electrons are taken up was identified. Finally, by capitalizing on fundamental knowledge, a biohybrid system was designed to grow nitrogen-fixing bacteria in association with electrodes for light-driven production of fixed nitrogen that has potential to be used as a fertilizer for plant growth.
Gaining an in-depth understanding of nitrogenase provides insight into one of the most challenging biological reactions, and the newfound knowledge may be a catalyst in developing more efficient systems for sustainable ammonia production.

description: Abstract

The exploration of human consciousness and the nature of reality within the cosmic order is a multifaceted endeavor, deeply enriched by the interplay between philosophy, Islamic religion, and the empirical science. In the African context, this interplay is particularly vibrant, given the continent's rich tapestry of cultural, spiritual, and intellectual traditions. Adopting an analytic and integrative approach, this paper critically investigates how the traditional African thought system, their indigenous religious practices, and the contemporary scientific approaches collectively contribute to a holistic understanding of consciousness and reality within the continent framework. African philosophy, with its emphasis on communalism, interconnectedness, and the integral role of spirituality, provides a unique lens through which to view consciousness as an entity that transcends individual existence. Indigenous African religions further this perspective by embedding consciousness within a cosmological framework where the material and spiritual realms are inseparable. These traditions often highlight the importance of ancestral spirits, nature, and the concept of a life force that permeates all existence. Complementing these perspectives, contemporary scientific approaches in Africa, from neuroscience to quantum physics, offer empirical insights that can both challenge and enhance traditional understandings. The synthesis of these diverse viewpoints fosters a dynamic discourse that not only deepens our comprehension of human consciousness and reality but also emphasizes the importance of integrating traditional wisdom with modern scientific inquiry. This integration underscores the significance of an African-centered epistemology in contributing to global philosophical, religious, and scientific debates on the nature of existence within the cosmic order.
title: An Experimental Comparison of Student Motivation Between Two Computational Thinking-Based STEM Activities: Vex-Based Automation and Robotics and a Quadcopter Activity
Creators: name: Ortiz, Cory J.

description: The purpose of this study was to compare student motivation between two junior high level computational thinking based STEM curricular activities. These two activities were a newly developed quadcopter based curriculum and a VEX based curricular activity developed for Project Lead the Way’s Gateway to Technology – Automation and Robotics course. Student motivation was assessed using an assessment called My Class Activities which broke motivation into four constructs: interest, challenge, choice, and enjoyment.
This study assessed students in three schools in a northern Utah school district. Students were assessed after receiving each curriculum. Assessment responses were then coded and analyzed. The results of this study suggested that though the junior high VEX curriculum was more challenging and offered students more choice than the quadcopter curriculum, the teacher delivering the curriculum had more to do with student motivation.
Explaining PAMELA and WMAP data through Coannihilations in Extended SUGRA with Collider Implications

description: The PAMELA positron excess is analyzed within the framework of nonuniversal SUGRA models with an extended $U(1)^n$ gauge symmetry in the hidden sector leading to neutralino dark matter with either a mixed Higgsino-wino LSP or an essentially pure wino dominated LSP. The Higgsino-wino LSP can produce the observed PAMELA positron excess and satisfy relic density constraints in the extended class of models due to a near degeneracy of the mass spectrum of the extended neutralino sector with the LSP mass. The simultaneous satisfaction of the WMAP relic density data and the PAMELA data is accomplished through a co-annihilation mechanism ($B_{\rm Co}-mechanism$), and leads to predictions of a neutralino and a chargino in the mass range (180-200) GeV as well as low lying sparticles accessible at colliders. We show that the models are consistent with the antiproton constraints from PAMELA as well as photon flux data from EGRET and FERMI-LAT. Predictions for the scalar neutralino proton cross section relevant for the direct detection of dark matter are also discussed and signatures at the LHC for these PAMELA inspired models are analyzed. It is shown that the mixed Higgsino-wino LSP model will be discoverable with as little as 1 fb$^{-1}$ of data and is thus a prime candidate for discovery in the low luminosity runs at the LHC.

description: The transformation of legislative processes in the Information society: from eLegislation to eParliament
 
 
This research analyzes, by means of an interdisciplinary and comparative approach, the transformation of legislative processes produced by the introduction of new ICT technologies.
 
The use of ICT  in support of parliamentary activities is concerned with efficiency of parliamentary process and aims at more transparent procedures, improved access to documents, social participation and cooperation among institutions. With ICT Parliaments are now able to improve their efficiency and optimize their business; they can advance the dialogue with their citizen both, through the real access and the effective availability of information and, through new way of participation in the democratic process. Finally, sharing information, know-out, best practices and other records, Parliaments will be able to develop new information and knowledge and to strengthen the role and power of Institutions.
 
 
Only through a global vision of the full process, re-thinking and develop rules and uniform standard and so implementing the new opportunities carrying out by ICT, it will be possible to put in practice concrete eParliament results.
 
The Research goals are at least three:
 
1. To Analysed the legislative process and the ICT opportunities to understand the impact of the latter on the former. In particular to check up the problems that  ICT can raise in relation of the constitutional principles ensuring the process itself.
2. To realized  an abstract model representing the legislative process regardless of  the form of government, chambers composition, legal system, etc.
3. To suggest standard, structural, linguistic and ontological, able to implement the new opportunities of sharing, cooperation and reuse among the many and various stakeholders of the democratic/legislative view.

description: We present new results on the thermal production yield of a hypothetical state made of six quarks $uuddss$ assuming its production in heavy-ion collisions at the CERN LHC. A state with this quark content and mass low enough to be stable against decay in timescales of the order of the age of the Universe, has been hypothesized by one of us (G.F.) and has been discussed as a possible dark matter candidate. In this work we address for the first time the thermal production rate that can be expected for this state in heavy-ion collisions at colliders. For this estimate we use a thermal model which has been shown to describe accurately the production of hadrons and nuclei in heavy-ion collisions at LHC energy. This estimate is of great relevance for sexaquark searches at colliders as well as for its consideration as a dark matter candidate and for the composition of neutron stars.
