Vertical Integration and Operational Flexibility
Creators: name: Moretto, Michele

Publisher: name: Alma Mater Studiorum - Università di Bologna
Year: 2008
Subjects: SECS-P/02 Politica economica

description: The main aim of the paper is to highlight the relation between flexibility and vertical integration. To this purpose, we go through the selection of the optimal degree of vertical disintegration of a flexible firm which operates in a dynamic uncertain environment. The enterprise we model enjoys flexibility since it can switch from a certain amount of disintegration to vertical integration and viceversa. This means that the firm never loses vertical control, i.e., the ability to produce all inputs even when it buys them in the market. This sort of flexibility makes for results which are somehow contrary to the Industrial Organization recent literature and closer to the Operations Research results. In this sense we provide a bridge between the two approaches and rescue Industrial Organization from counterintuitive conclusions.

description: We develop scenarios for reducing carbon dioxide emissions from the electricity sector in the upper Midwest (Wisconsin, Illinois, Minnesota, Iowa, North Dakota, South Dakota, Montana, Wyoming, and Manitoba) by 80% relative to 1990 levels. The report has three major components: 1) an inventory of CO2 emissions from all fossil fuel combustion in the region from 1960-2001, subdividing by economic sector and specific electricity generating station; 2) an evaluation of all electricity resources in the region and all technologies for utilizing them, taking into account the overall scale of the resource, technology costs, and other issues that influence the selection of a certain technology; and 3) the development of a simulation model to examine the impact of various factors (policies, prices, technologies, resources) on the regional electricity supply and its emissions from 2005-2055.

description: We study the distribution dynamics of the demand for books in Italy. We
find that for each of three broad sub-markets in which the book
publishing industry can be classified − Italian novels, foreign novels and
essays − sales over a three-year sample can be adequately fitted by a
power law distribution. Our results can be plausibly interpreted in terms
of a model of interactions among buyers exchanging information on the
books they buy.
Frustrated Heisenberg antiferromagnets: fluctuation induced first order vs deconfined quantum criticality

Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)
subject: FOS: Physical sciences

description: Recently it was argued that quantum phase transitions can be radically different from classical phase transitions with as a highlight the 'deconfined critical points' exhibiting fractionalization of quantum numbers due to Berry phase effects. Such transitions are supposed to occur in frustrated ('$J_1$-$J_2$') quantum magnets. We have developed a novel renormalization approach for such systems which is fully respecting the underlying lattice structure. According to our findings, another profound phenomenon is around the corner: a fluctuation induced (order-out-of-disorder) first order transition. This has to occur for large spin and we conjecture that it is responsible for the weakly first order behavior recently observed in numerical simulations for frustrated $S=1/2$ systems.

description: The results of simulation modelling carried out with GLEAMS on hypothetical scenarios driven by the Reform of Common Agricultural Policy are presented. The model was set up with data collected in recent research projects to simulate a typical cultivated environment of the Venetian Plain (north east Italy) where field experiments are in progress. Agro-environmental simulations were conducted over a long period using a 30-year whether record. First single crops, then entire rotations and finally the whole farm production patterns were simulated, based on the present standard agrotechnologies of the study area and on proposed low input systems. The alternative farm scenarios were taken from those hypthesised by economists on the basis of the recent Common Agricultural Policy (CAP) Reform with multi-objective modelling. Environmental evaluation of alternative scenarios was carried out with 6 proposed indexes quantifying water pollution due to nutrient and pesticide releases associated with leaching and runoff phenomena. The environmental indexes focus on the efficiency of applied agrochemicals, regulatory and toxicity limits for drinkable water and risks for aquatic ecosystems (fish toxicity and eutrophication). The results confirmed the potential risks of intensive cultivation systems, in particular when livestock wastes are distributed, and the various levels of efficacy of proposed eco-compatible systems to mitigate water pollution phenomena.

Subjects: Community/Rural/Urban Development

description: "The implementation of the new Common Agricultural Policy (CAP) has brought far-reaching consequences for rural development: the farmer, liberating himself from his one and only role of producer, can profit from the opportunities and synergies offered by other activities that are complementary and alternative to agriculture. Thus the farmer has an essential role in the valorization of endogenous resources of the area where he carries his activities on. Since 1975, the European Community has financed programmes which have increasingly taken into account the rural development dimension in research activities linked to agriculture (for example the AGRIMED and the CAMAR research programmes). Central to such researches is the notion of endogenous development. While this is still not a well defined paradigm, it seems to have some nice explanatory categories which could be worth to discuss in a conference where different experiences (i.e. North American and European) are compared. This is the main purpose of the paper. A second objective of the paper is to analyze if the framework of the endogenous development could have useful insight (or, at least, could be suitable) for the analysis of sustainability issues.
Sustainability of Open Access journals: a short review

Subjects: subject: Library and Information Studies
subject: FOS: Media and communications

description: This short review starts with a description of types of Open Access journals according to their financial management. Their funding sources could be internal -generated by the publisher or journal activity- or external –not generated by them. Internal types of funding are APCs, community publishing, off-print sales, publicity, sponsorship, and others. The external sources are membership fees, member schemes, public funding, collaborative purchasing models and discounts through institutional subscriptions. APCs are present on 75% of the embargoed OA journals, while only 25% in full-OA titles; they are paid in the 90% of the cases by authors sponsors, not by authors themselves. OA publishing model is cheaper than the classical subscription-based model. Some factors regarding the most important sources for revenue for OA journals are mentioned, according to previous deep studies. A business model is composed by three dimensions –economic, operative and strategic-, and the success and viability of the journal depends on the diversification of the revenue sources. Finally, some conclusions are given.

description: This paper presents the results of studies in the floodplain system of North Vietnam of fish infestation by the larvae of Clonorchis sinensis with an analysis of scientific publications on this topic. It has been established that the highest rates of fish infestation with cysts of the clonorchiasis pathogen are recorded in fish-breeding reservoirs in the floodplain of the Hongha River (Red River). The contamination of fish resources in natural reservoirs with C. sinensis metacercariae is much lower than in fish ponds. In urban water bodies and fish ponds with sewage, the invasion of hepatic trematodes is much lower than that of intestinal trematodes.

description: We present Chandra and XMM observations of 12 bright (f(2-10 keV) > 10^-13 cgs) sources from the ASCA SHEEP (Search for the High Energy Extragalactic Population) survey. Most of these have been either not observed or not detected previously with the ROSAT mission and therefore they constitute a sample biased towards hard sources. The Chandra observations are important in locating with accuracy the optical counterpart of the X-ray sources. Optical spectroscopic observations show that our sample is associated with both narrow-line (NL) (six objects), and Broad-Line (BL) AGN (five objects) with one source remaining unidentified. Our sources cover the redshift range 0.04 to 1.29 spanning luminosities from 10^42 to 10^45 cgs (2-10 keV). The NL sources have preferentially lower redshift (and luminosity) compared with the BL ones. This can be most easily explained in a model where the NL AGN are intrinsically less luminous than the BL ones in line with the results of Steffen et al. The X-ray spectral fittings show a roughly equal number of obscured (N_H>10^22 cgs) and unobscured (N_H<10^22 cgs) sources. There is a clear tendency for obscured sources to be associated with NL AGN and unobscured sources with BL ones. However, there is a marked exception with the highest obscuring column observed at a BL AGN at a redshift of z=0.5.

Synthesis and characterization of thermally stable acidic forms of zeolite A
Creators: name: Sawada, James Alexander
Publisher: name: University of British Columbia
Year: 2009

description: Zeolite A has several attributes which make it attractive as a solid acid catalyst. The framework has pores on the order of 4-5 Å which show a strong selectivity toward small molecules by excluding species with larger diameters than linear hydrocarbons. The pores intersect to form a 3-dimensional channel network which is advantageous as it allows for free diffusion throughout the entire structure. Furthermore, zeolite A is already commercially available and is inexpensive to produce. Acidic forms of zeolite A , however, have long been considered unachievable as a result of the reduced stability of the zeolite A framework compared to those of more siliceous zeolites. This thesis describes the preparation and characterization of a series of zeolite A materials which demonstrate both thermal stability and Bronsted acidity. Zeolite A materials were prepared whose frameworks contained both C a ²⁺ and NH₄⁺ ions. The three materials studied had Ca ²⁺: NH₄⁺ ratios of 70:30, 60:40, and 50:50. The materials were systematically examined using powder X-ray diffraction, electron microscopy, solid-state NMR, and gas physisorption to establish their homogeneities and thermal stabilities. Finally, catalytic testing of the materials for the conversion of methanol to olefins was carried out to establish their activity in a model acid-catalyzed reaction.

description: The Wroblewski parameter is a convenient indicator of strangeness production and can be employed to monitor a signal of quark-gluon plasma production : enhancement of strangeness production. It has been shown to be about a factor two higher in heavy ion collisions than in hadronic collisions. Using a method proposed by us earlier, we obtained lattice QCD results for the Wroblewski parameter from our simulations of QCD with two light quarks both below and above the chiral transition. Our first principles based and parameter free result compare well with the A-A data from SPS and RHIC.

description: The problem of the resolution of turbulent flows in adaptive mesh refinement (AMR) simulations is investigated by means of 3D hydrodynamical simulations in an idealised setup, representing a moving subcluster during a merger event. AMR simulations performed with the usual refinement criteria based on local gradients of selected variables do not properly resolve the production of turbulence downstream of the cluster. Therefore we apply novel AMR criteria which are optimised to follow the evolution of a turbulent flow. We demonstrate that these criteria provide a better resolution of the flow past the subcluster, allowing us to follow the onset of the shear instability, the evolution of the turbulent wake and the subsequent back-reaction on the subcluster core morphology. We discuss some implications for the modelling of cluster cold fronts.

description: The management of water resources is today one of the main issues in most countries. In Italy, as in many other European countries, irrigation is the main sector using water and hence it is at the centre of the water policy agenda. Water management for irrigation requires suitable policy tools able to meet social objectives and private behaviour. The legal framework in the European Union is today faced with the new Water Framework Directive (60/2000), that sets up new criteria for water management, regulation and pricing. Among other things, the Water Framework Directive introduces the principle of full cost recovery and the polluter pays principle for water users. For many areas of Italy, this may be a significant shift compared to present payment criteria, based on traditional rights, area prices, and only a partial cost recovery from final users. The objective of this paper is to analyse the problem of water regulation for irrigated agriculture, through a simulation model based on the integration of a mathematical decision making model and a principal agent. The methodology allows to quantify water demand and optimal regulation from the point of view of the policy maker. The results show major impacts of water availability and prices on farm income. The adoption of a mix of pricing instruments related at the same time to charges associated to crop mix, water consumption and pollution can significantly improve water policy efficacy.

description: In the world today, bronchial asthma is a serious disease, with long-lasting attacks of suffocation, occurring with severe respiratory failure, threatening the life of patients, remains one of the most pressing problems in med-icine. Despite the improvement in the methods of diagnosis and treatment of bronchial asthma, the incidence of morbidity, disability and mortality from this disease is increasing from year to year all over the world. The article provides an analysis of the incidence of bronchial asthma and the leading risk factors in the Syrdarya region of the Republic of Uzbekistan. The obtained results show that the majority of patients with bronchial asthma have a genetic tendency. The work schedule of patients is improperly organized, there are many harmful occupational factors. Living conditions, family psychological environment, patients' attitude to medical services are not satis-factory. Frequent acute respiratory viral infections, bad habits, genetic predisposition, age composition, attitude to one's health, diet, alcohol consumption, going to a doctor with an acute form of the disease, social status, nature of work, attitude to medical care are the leading risk factors for the disease.

description: The purpose of this brief article is to assess the current controversy over Genetically Modified Organisms (GMOs) in agriculture and its potential implications for the global trading system. More importantly, it offers a solution to the serious potential for injury to this system, to be developed below. The remainder of this article is divided into three sections. The next section will discuss labeling of GMO agricultural products, distinguishing between issues of food products and those affecting seed. Next, it will argue in favor of a particular type of "negative" label ("this product contains no GMOs") as distinct from a "positive" label ("this product may contain GMOs"). This proposal draws on the U.S. experience in the dairy sector with milk from cows treated with recombinant bovine somatotropin, or rBST. Finally, it concludes with a discussion of issues which are left unresolved by the labeling proposal, and some of the remaining challenges posed by GMOs for the global food and agricultural system.

description: Assuming that the Casimir scaling hypothesis is well verified in QCD, masses of glueballs and hybrid gluelumps (gluon with a point-like $c\bar c$ pair) are computed within the rotating string formalism. In our model, two gluons are attached by an adjoint string in a glueball while the gluon and the colour octet $c\bar c$ pair are attached by two fundamental strings in a hybrid gluelump. Masses for such exotic hadrons are computed with very few free parameters. These predictions can serve as a guide for experimental searches. In particular, the ground state glueballs lie on a Regge trajectory and the lightest $2^{++}$ state has a mass compatible with some experimental candidates.

description: The worldline variational approach is extended beyond the quenched approximation, i.e. to include virtual pair production of heavy particles. This is achieved either by an expansion of the functional determinant to second order or by an hybrid ansatz for the quadratic trial action consisting of fields for the light particles and worldlines for the heavy ones as in the linear polaron model. Numerical results and analytic approximations show a reduction of radiative effects with increasing number of flavors.

description: Alternative hypotheses of market integration in the U.S. winter market for fresh tomatoes were evaluated using a dynamic model of spatial price adjustment. The results showed that while Florida and Mexico were integrated in the same market, a price change in one area was not instantaneously reflected in the other. Lagged effects were important with long-run integration being supported for both Florida and Mexico and short-run integration for Mexico. However, the information flow, while relatively efficient, was not symmetric. Florida was found to be dominant in the price formation process with Mexico responding to changes in the Florida price.

We discuss a SUGRA implementation of chaotic inflation in the presence of moduli fields, and find that inflation does not work with a generic KKLT moduli stabilisation potential. A viable model can be constructed with a fine-tuned moduli sector, but only for a very specific choice of Kahler potential. Our analysis also shows that inflation models satisfying \partial_{i} W_{\rm inf}=0 for all inflation sector fields ϕ_i can be combined successfully with a fine-tuned moduli sector.

This paper reports on a study which developed a mixed-integer programming model of the U.S. sorghum sector to (1) determine the least-cost geographic location for new cleaning investment at the country, terminal and port elevator stages of the marketing system and (2) measure additional system marketing costs associated with implementing the proposed standards. Results show the least-cost cleaning location to be at country and terminal elevators in excess supply regions. Implementing the proposed standard would increase system costs about 2 percent.

The study's specific objectives were to determine the effect of stamp duties on real gross domestic product and to examine the effect of capital gain tax on real gross domestic product in Nigeria. The ex-post facto design method was used in this study while secondary data were used were gathered from various governmental agencies such as Federal Inland Revenue Service (IFRS) 2022 Statistics Report, the World Bank, UNDP, and OECD Stat. covering a period of 21years (2002-2022). Multiple regression models were employed via the Ordinary Least Square (OLS) method and it was found that Stamp duties and capital gain tax have significant effect on Real Gross Domestic Product in Nigeria as p-value of 0.00 < 0.05. the study concludes that Nigeria's real gross domestic product was significantly impacted by taxation taxes from 2002 to 2022. The study recommends that the values of taxation taxes which has contributed to the Nigerian economy should also be raised.

description: The problem of resistant infections has not only clinical (increased mortality, including among people of working age, disability of patients), but also economic consequences. Thus, at the level of the healthcare system, additional costs are associated with an increase in the consumption of resources of the healthcare system (addi-tional days in the intensive care unit, prolongation of hospitalization, additional diagnostic studies, surgical inter-ventions, etc.), at the level of society, economic losses are associated, among other things, with the inefficiency of other medical technologies, the use of which is accompanied by the appointment of antimirobial drugs (bone mar-row transplantation, nursing of newborns with low body weight, etc.). In this regard, it is relevant to study the antimicrobial effect of the drug of “Kartulex”. The conducted studies have shown that when studying the antimi-crobial action, it was found that Kartulex in dilutions 1:2500, 1:5000, 1:7500, 1:10000 distilled water completely suppresses the growth of Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa and Acinetobacter calcoaceticus. With prophylactic intragastric administration 24 hours before infection of mice with a lethal dose of Staphylococcus aureus, Kartulex prevents the development of a deadly staphylococcal infection in animals. At an optimal dose of 0.01 mcg/kg, Kartulex increases the survival rate of mice to 75.0% with 83.3% death in the control.

We consider physical systems described by smooth microscopic interaction potentials V_N(q), among N degrees of freedom, and the associated family of configuration space submanifolds {M_v}_{v \in R}, with M_v={q \in R^N | V_N(q) \leq v}. On the basis of an analytic relationship between a suitably weighed sum of the Morse indexes of the manifolds {M_ v}_{v \in R} and thermodynamic entropy, the Theorem states that any possible unbound growth with N of one of the following derivatives of the configurational entropy S^{(-)}(v)=(1/N) \log \int_{M_v} d^Nq, that is of |\partial^k S^{(-)}(v)/\partial v^k|, for k=3,4, can be entailed only by the weighed sum of Morse indexes. Since the unbound growth with N of one of these derivatives corresponds to the occurrence of a first or of a second order phase transition, and since the variation of the Morse indexes of a manifold is in one-to-one correspondence with a change of its topology, the Main Theorem of the present paper states that a phase transition necessarily stems from a topological transition in configuration space. The proof of the Theorem given in the present paper cannot be done without Main Theorem of paper I.

description: Experiments and studies were conducted to investigate the role of social capital. Social capital (relationship to others) is a productive asset which is a substitute for and complement to other productive assets. The productivity of social capital leads to the expectation that firms and individuals invest in relationships. Data were collected to answer the following questions: Does the identity (relationship) of trading partners affect selling and buying prices; the acceptance of catastrophic risk; the choice of share or cash leases in agriculture; loan approval; and the banks investment to retain customers? The evidence is in the affirmative.

description: Studies have shown that daily intragastric administration of Kartulex to Wistar rats for 3 months at doses of 4.3 and 12.9 mcg/kg (10and 30-fold estimated higher daily therapeutic doses for humans) does not affect the general condition and behavior of rats, as well as hematological and biochemical parameters. The data obtained indicate the good tolerability of Kartulex and the absence of its damaging effect (according to biochemical tests) on the functional state of the most important organs and body systems of experimental animals with prolonged intragastric administration of kartulex in tested doses of 4.3 and 12.9 mcg/kg.

description: We present analysis from simultaneous FUSE, ASCA, and EUVE observations, as well as a reanalysis of archival HST spectra, from the extreme Narrow-line Seyfert 1 Galaxy RE 1034+39 (KUG 1031+398). RE 1034+39 has an unusually hard spectral energy distribution (SED) that peaks in the soft X-rays. Its emission lines are unusual in that they can all be modelled as a Lorentzian centered at the rest wavelength with only a small range in velocity widths. In order to investigate whether the unusual SED influences the emission line ratios and equivalent widths, we present three complementary types of photoionization analysis. The FUSE spectrum was particularly important because it includes the high-ionization line OVI. First, we use the photoionization code Cloudy and the SED developed from the coordinated observations to confirm that the emission lines are consistent with observed hard SED. The best model parameters were an ionization parameter log(U) ~ -2 and a hydrogen number density log(n_H)=9.75 [cm^-2]. Second, we present a Locally Optimally-emitting Cloud model. This model produced enhanced OVI as observed, but also yielded far too strong MgII. Third, we develop a series of semi-empirical SEDs, run Cloudy models, and compare the results with the measured values using a figure of merit (FOM). The FOM minimum indicates similar SED and gas properties as were inferred from the one-zone model using the RE 1034+39 continuum. Furthermore, the FOM increases sharply toward softer continua, indicating that a hard SED is required by the data in the context of a one-zone model.

description: One of the most important mathematical tools necessary for Quantum Field Theory calculations is the field propagator. Applications are always done in terms of plane waves and although this has furnished many magnificent results, one may still be allowed to wonder what is the form of the most general propagator that can be written. In the present paper, by exploiting what is called polar form, we find the most general propagator in the case of spinors, whether regular or singular, and we give a general discussion in the case of vectors.

subject: Oligopoly

description: This experiment demonstrates principles of decision-making in dynamic oligopolies, especially the difficulties in forming and maintaining cartels. As an illustration of firm behavior under imperfect competition, the game distinguishes between procedurally rational choices and substantively rational decisions in the context of collusive, Cournot, and competitive equilibria. The paper discusses results from an actual classroom exercise and suggests some additional variations in institutional details. Instructions for students and a spreadsheet program for producing payoff tables are provided in the appendices.

description: In the article, based on the readings of the Tanita BC – 545N body composition analyzer and on morphological data calculated by simple anthropometric measurements according to Watson P.E., data on the total water content in the body of young men who are part of the Syrian national road racing team at the pre-competition stage of the training process are presented. It was found that the total water content of 18-year-old boys at the pre-competition stage of preparation for the Asian Championship is 62.99%, and 65.01% for 19-year-old boys, which is regarded, firstly, as a physiologically balanced component composition of the body. Secondly, about the competent con-struction of the training process.

Material examined
ESTONIA • 1 spec.; Moe trench; Kõrgessaare Formation, Vormsi Regional Stage; GIT 878-116.
Description
Specimen GIT 878-116 is a ca 12 mm long internal mold of parts of a mature body chamber and three phragmocone chambers with a circular conch cross section. The maximum diameter of the specimen is 10 mm at its adoral end. At the base of the body chamber the diameter is 9.8 mm and the adapicalmost chamber has a diameter of 9.6 mm (angle of expansion 2.5°). The three preserved chambers of the phragmocone decrease in length from 2.4 mm to 1.5 mm, to 0.5 mm adorally. The septal foramen is well preserved at 1.7 mm from the conch margin, where the conch cross section is 9.6 mm in diameter (RSP = 0.18), with a diameter of 1.1 mm (RSH = 0.11). The conch surface is apparently smooth, although fine details of the ornamentation are not preserved.
Remarks
This specimen can be related to I. junceum (Hall, 1847) with respect to the mature conch size, position of the siphuncle, and general conch shape. However, because the crucial details of the conch surface are not preserved, a species level determination is not possible.

description: This article is devoted to some important problems of education. It is underlined that in modern society we observe really great changes in many fields: policy, economy, communication, international contacts etc. In such conditions the system of education can’t be the same as it was during the last one or two centuries. In response to the establishment of standardized and compulsory education alternative and after-school education grew up. These forms of education are especially popular in America. In the USA a variety of educational alternatives exist at the elementary, secondary and some other levels. Alternative and after-school education provide special educational conditions for the personal development of each pupil. The main features of these forms of education are analyzed.

description: Obtaining estimates of pesticides productivity is an economic response to the growing public concern about the steady increase of pesticide use in the United States. This type of research indicates the cost of limiting pesticide use in terms of foregone output. Pervious empirical studies give a "snap-shot", or "average", look at pesticide productivity. This research effort employs a random coefficient model to determine the trend of the marginal value product of pesticides in agriculture in the United States. Results show a distinct downward trend in two states, Iowa and Texas. California, however, shows no evidence of a downward trend.

description: [ReO(ppme)X] (where ppme²⁻ is 2,5-diazo-N,N'-dimethylhexyl-l,6- bis(phenylphosphinate), X = Br₀․₃Cl₀․₇) has been synthesized via a substitution reaction and structurally characterized. [ReO(ppme)Cl] has been prepared by a reduction/complexation reaction from [NH₄][ReO₄]. [ReO(ppme)Cl] reacts with thiocyanate and benzene thiolate forming [ReO(ppme)X] (X = ⁻NCS, ⁻SC₆H₅), but the one-pot synthesis of the respective ternary thiolate complexes from perrhenate was not successful. The reduction/complexation reaction of p-methoxybenzenethiol, H₄ppmeCl₄, and perrhenate resulted in the formation of [H₃ppme][ReO(SR)₄], the reaction of which with ReO(ppme)Cl does not lead to [ReO(ppme)SR] in high yields. The oxorhenium(V) complexes with Hapmen (N,N'-bis(2- pyridylmethyl)ethylenediamine, an N₄ ligand) and H₂bped (N,N'-bis(2- pyridylmethyl)ethylenediamine-N,N'-diacetic acid, an N₄O₂ ligand) have been synthesized and structurally characterized. Along with [ReO(bbpen)]⁺ (where H₂bbpen is N,N'-bis(2- hydroxybenzyl)-N,N'-bis(2-methylpyridyl)ethylenediamine, an N₄O₂ ligand) and [ReO(qtp)(OCH₃)₂]⁺ (where qtp, 2,2'-6',2"-6",2,"-quaterpyridine, has an N₄ donor set), [ReO(H₂pmen)Cl₂]+ and [ReO(bped)]⁺ complexes share a rare seven-coordinate structure with a distorted pentagonal bipyramidal geometry, which represents a potentially general structural motif in Re[sup v]=0 complexes. The complexes retained their structure in solution. [The rest of the abstract can be found in attached PDF file]
