    Much of the structure of macroscopic evolution equations for relaxation to equilibrium can be derived from symmetries in the dynamical fluctuations around the most typical trajectory. For example, detailed balance as expressed in terms of the Lagrangian for the path-space action leads to gradient zero-cost flow. We expose a new such fluctuation symmetry that implies GENERIC, an extension of gradient flow where a Hamiltonian part is added to the dissipative term in such a way as to retain the free energy as Lyapunov function.

    The degradation of benzidine in aqueous solution by the low temperature plasma was examined. The results showed that the concentration of medium and the value of pH have an appreciable effect on the degradation of benzidine. What is more important is that iron ions acting as a catalyst play an important role in this reaction. For exploring the degradation mechanism of benzidine, some of the intermediate products were recorded by HPLC (high performance liquid chromatography)

    Generic sentences are simple and intuitive recognition and objective description to the external world in terms of "class". In the long evolutionary process of human being's language, the concepts represented by generic sentences has been internalized to be the defaulted knowledge in people's minds. In Chinese, some rhetorical expressions supported by corresponding generic sentences can be accepted by people. The derivation of these rhetorical expressions from the corresponding generic sentences is an important way for language to evolution, which reflects human's creative cognitive competence. From the perspective of conceptual blend theory and the theory of categorization of the cognitive linguistics, the goal of this paper is to analysis the process of the derivation of the rhetorical expressions from the corresponding generic sentences, which can facilitate the Chinese metaphorical information processing and the corpus construction of Chinese emotion metaphors.

  7. Benzidine-based dyes: effects of industrial practices, regulations, and world trade on the biological stains market.

    2009-06-01

    One of the most sweeping changes in the dye industry since the advent of synthetic dyes grew out of the health risks associated with benzidine. Dyes made from benzidine and its derivatives were used around the world until adverse health effects become incontrovertible. Workers and family members of workers involved in production and use of benzidine-based dyes had a high incidence of bladder cancer. Following publication of several reports documenting this health hazard, dye makers in the USA, Europe, and Japan phased these dyes out of production in the 1970s. Government regulations lent legal support for these voluntary initiatives. Two strategies subsequently evolved to compensate: developed nations brought alternative substances to market while emerging countries increased production of carcinogenic dyes and sold them at discount prices around the world. Nearly all dye manufacturing now has moved away from nations whose costs of production and compliance rendered them unable to compete. The purpose of this brief review is to publicize the health risks associated with dyes made from benzidine and its congeners, and to alert all companies and end users handling these dyes for biomedical applications that composition of the product and lot-to-lot variability may be problematic because of the manufacturing and distribution practices of the countries where they are produced.

    Bioactivation of carcinogens by peroxidases has received increasing attention since the discovery of the oxidation of carcinogens by prostaglandin hydroperoxidase. Benzidine and 3,5,3',5'-tetramethylbenzidine are oxidized by horseradish peroxidase and prostaglandin synthase to two-electron oxidation products (di-imines). Di-imines readily react with the phenolic anti-oxidant butylated hydroxyanisole to form adducts. In this paper, we have studied the oxidation of benzidine by horseradish peroxidase in the presence of phenolic compounds and characterized the resultant benzidine/phenol adducts. A benzidine/2,6-dimethylphenol adduct was isolated and characterized by mass spectrometry and high field n.m.r. The reaction of [ 14 C]benzidine in the presence of horseradish peroxidase and phenol yielded only the benzidine/phenol adduct. Our results indicate that the benzidine/phenol adducts are analogous to the indoaniline dyes, differing only in substitution of a biphenyl group for a benzene ring. The reaction of benzidine di-imine with endogenous phenols may represent a new pathway for detoxication, removing potentially harmful metabolites of benzidine

    Decomposition of 14 C-labeled benzidine, α-naphthylamine, and p-toluidine in soil was studied in laboratory experiments by monitoring CO 2 production during a 308- to 365-d incubation period. The importance of microbial activity in decomposition of all three aromatic amines was shown by decreased 14 CO 2 evolution in 60 Co treated soils. After 365 d of incubation, 8.4 to 12% of added benzidine (54.3 μmol kg -1 ) was evolved as CO 2 while 17 to 31% of added α-naphthylamine (69.8 μmol kg -1 ) and 19 to 35% of added p-toluidine (93.3 μmol kg -1 ) were evolved as CO 2 in 308 d. Decomposition was enhanced by increasing the temperature from 12 to 30 0 C. For benzidine, both the amount and proportion decomposed increased with an increase in application rate. Decomposition of aromatic amines was not enhanced by the addition of decomposable substrates. Differences in decomposition of aromatic amines occurred among soils, but consistent relationships between decomposition of amines and soil properties were not observed. In batch equilibration studies, the Freundlich equation described aromatic amine sorption. Isotherms were nonlinear for benzidine and 1 -naphthylamine and linear for p-toluidine. Desorption of sorbed amines followed the order: benzidine < p-toluidine < α-naphthylamine and was inversely related to the extent of decomposition

    Benzidine, a compound bearing aromatic rings and terminal amino groups, was employed for the intercalation and simultaneous reduction of graphite oxide (GO). The aromatic diamine can be intercalated into GO as follows: (1) by grafting with the epoxy groups of GO, (2) by hydrogen bonding with the oxygen containing groups of GO. Stacking between benzidine aromatic rings and unoxidized domains of GO may occur through π-π interaction. The role of benzidine is influenced by pH conditions and the weight ratio GO/benzidine. Two weight ratios were tested i.e. 1:2 and 1:3. Under strong alkaline conditions through K2CO3 addition (pH ∼10.4-10.6) both intercalation and reduction of GO via amino groups occur, while under strong acidic conditions through HCl addition (pH ∼1.4-2.2) π-π stacking is preferred. When no base or acid is added (pH ∼5.2) and the weight ratio is 1:2, there are indications that reduction and π-π stacking occur, while at a GO/benzidine weight ratio 1:3 intercalation via amino groups and reduction seem to dominate. The aforementioned remarks render benzidine a multifunctional tool towards production of reduced graphene oxide. The effect of pH conditions and the GO/benzidine weight ratio on the quality and the electrochemical properties of the produced graphene-based materials were investigated. Cyclic voltammetry measurements using three-electrode cell and KCl aqueous solution as an electrolyte gave specific capacitance values up to ∼178 F/g. When electric double-layer capacitors (EDLC) were fabricated from these materials, the maximum capacitance in organic electrolyte i.e., tetraethyl ammonium tetrafluoroborate (TEABF4) in polycarbonate (PC) was ∼29 F/g.

    In the effort to find alternatives for low cost adsorbent, activated carbon using sugarcane bagasse (SBAC) has been introduced in this study that has undergo chemical treatment using phosphoric acid to determine the effectiveness of adsorption process in removing o-toluidine and benzidine. Throughout this study, 92.9% of o-toluidine has been successfully removed by SBAC at optimum value of 1.1 g of dosage with contact time of 10 minutes and concentration of 10 mg/L. While benzidine was remove by 83.1% at optimum dosage of 1.1 g with 60 minutes of contact time and at 20 mg/L concentrations. Testing of SEM proves that SBAC has high porosity and comparable to CAC. In FTIR results, shows that CAC has high number of double bond while SBAC shows no double bond at all. Presence of double bond in CAC lead to increase in percentage of removal of adsorbate. After considering other factor such as cost, energy and environmental friendly, it shows that SBAC was considerable to replaced CAC.

    2009-01-01

    This paper analyzes the Generic Clearance Values established for natural and artificial radionuclides with the objective of evaluating their degree of conservatism in views of adopting them into the regulatory body. Generic clearance values for natural radionuclides have been chosen by experts judgments as the optimum boundary between, on one hand, the ubiquitous unmodified soil concentrations and, on the other hand, activity concentrations in ores, mineral sands, industrial residues and wastes. For artificial radionuclides the clearance levels have been derived from the scenarios postulated in the document 'Safety Reports Series Nr 44' of the IAEA considering quantitative exemption criteria. A set of 8 scenarios were postulated covering external, ingestion and inhalation exposure pathways. For each radionuclide, the generic clearance level was derived as the more restrictive value obtained from the scenarios, that is the lowest ratio between the applicable individual dose and the dose per unit activity concentration (Bq/g). The individual dose was calculated by a formula depending on each scenario and pathway, with different parameters, such as exposure time, dosimetric factors, dilution factor, density of the material, geometric factors, etc. It was concluded that the basis and parameters used for the derivation of the generic clearance levels are quite conservative and therefore its the adoption in Argentina has been recommended. It is expected that their implementation will contribute to optimize the regulatory management system. (author)

    Full Text Available Environmental release of benzidine-based dyes is a matter of health concern. Here, a microbial consortium was enriched from textile dye contaminated soils and investigated for biodegradation of the carcinogenic benzidine-based dye Trypan Blue using wheat bran (WB as growth medium. The PCR-DGGE analysis of enriched microbial consortium revealed the presence of 15 different bacteria. Decolorization studies suggested that the microbial consortium has high metabolic activity towards Trypan Blue as complete removal of 50 mg∙L−1 dye was observed within 24 h at 30 ± 0.2 °C and pH 7. Significant reduction in TOC (64% and COD (88% of dye decolorized broths confirmed mineralization. Induction in azoreductase (500%, NADH-DCIP reductase (264% and laccase (275% proved enzymatic decolorization of dye. HPLC analysis of dye decolorized products showed the formation of six metabolites while the FTIR spectrum indicated removal of diazo bonds at 1612.30 and 1581.34 cm−1. The proposed dye degradation pathway based on GC-MS and enzyme analysis suggested the formation of two low molecular weight intermediates. Phytotoxicity and acute toxicity studies revealed the less toxic nature of the dye degradation products. These results provide experimental evidence for the utilization of agricultural waste as a novel low-cost growth medium for biodegradation of benzidine-based dyes, and suggested the potential of the microbial consortium in detoxification.

    Owing to their low glass transition temperature, T{sub g}, amorphous thin films of N,N′-bis(3-methylphenyl)-N,N′-bis(phenyl)benzidine (TPD) undergo morphological changes even at room temperature. It has been noticed previously that exposure to UV light can increase apparent T{sub g} of TPD films and thus stabilize their morphology. However, the reason behind increase in structural stability was not examined at the time. Here we present evidence that TPD molecules undergo photo-oxidation in air when exposed to λ ≈ 350 nm radiation and that less than 5% of the photo-oxidized species are needed to prevent dewetting of thin TPD films. We propose that photo-oxidized TPD species bind strongly to both ordinary TPD molecules and to terminal hydroxyl groups at the substrate surface, which decreases mobility of TPD molecules and makes thin TPD film less prone to morphology changes. - Highlights: • We made variable thickness TPD films and exposed them to UV light under ambient conditions. • Mass spectroscopy and proton NMR measurements of irradiated and pristine TPD films • TPD molecules undergo oxidation process under UV light irradiation. • Dipole–dipole interactions may be responsible for stabilization of morphological changes.

    Generic drugs have been used extensively in many developed countries, although their use in Japan has been limited. Generic drugs reduce drug expenses and thereby national medical expenditure. Because generic drugs provide advantages for both public administration and consumers, it is expected that they will be more widely used in the future. However, the diffusion rate of generic drugs in Japan is quite low compared with that of other developed countries. An investigation on generic drugs conducted by the Ministry of Health, Labour and Welfare in Japan revealed that 17.2 % of doctors and 37.2 % of patients had not used generic drugs. The major reasons for this low use rate included distrust of off-patent products and lower drug price margin compared with the brand name drug. The generic drugs available in the market include external drugs such as wet packs, antihypertensive agents, analgesics, anticancer drugs, and antibiotics. Among them, antibiotics are frequently used in cases of acute infectious diseases. When the treatment of these infections is delayed, the infection might be aggravated rapidly. The pharmacokinetics-pharmacodynamics (PK-PD) theory has been adopted in recent chemotherapy, and in many cases, the most appropriate dosage and administration of antibiotics are determined for individual patients considering renal function; high-dosage antibiotics are used preferably for a short duration. Therefore, a highly detailed antimicrobial agent is necessary. However, some of the generic antibiotics have less antibacterial potency or solubility than the brand name products. We showed that the potency of the generic products of vancomycin and teicoplanin is lower than that of the branded drugs by 14.6 % and 17.3 %, respectively. Furthermore, we confirmed that a generic meropenem drug for injection required about 82 s to solubilize in saline, whereas the brand product required only about 21 s. It was thought that the cause may be the difference in size of bulk

    2008-08-01

    Full Text Available We study the contact geometry of scalar second order hyperbolic equations in the plane of generic type. Following a derivation of parametrized contact-invariants to distinguish Monge-Ampère (class 6-6, Goursat (class 6-7 and generic (class 7-7 hyperbolic equations, we use Cartan's equivalence method to study the generic case. An intriguing feature of this class of equations is that every generic hyperbolic equation admits at most a nine-dimensional contact symmetry algebra. The nine-dimensional bound is sharp: normal forms for the contact-equivalence classes of these maximally symmetric generic hyperbolic equations are derived and explicit symmetry algebras are presented. Moreover, these maximally symmetric equations are Darboux integrable. An enumeration of several submaximally symmetric (eight and seven-dimensional generic hyperbolic structures is also given.

Generic PI treatments in use today are 150 Gy for all hosts of Tephritidae, 250 Gy for all arthropods on mango and papaya shipped from Australia to New Zealand, 300 Gy for all arthropods on mango shipped from Australia to Malaysia, 350 Gy for all arthropods on lychee shipped from Australia to New Zealand and 400 Gy for all hosts of insects other than pupae and adult Lepidoptera shipped to the United States. Efforts to develop additional generic PI treatments and reduce the dose for the 400 Gy treatment are ongoing with a broad based 5-year, 12-nation cooperative research project coordinated by the joint Food and Agricultural Organization/International Atomic Energy Agency Program on Nuclear Techniques in Food and Agriculture. Key groups identified for further development of generic PI treatments are Lepidoptera (eggs and larvae), mealybugs and scale insects. A dose of 250 Gy may suffice for these three groups plus others, such as thrips, weevils and whiteflies. - Highlights: ► The history of phytosanitary irradiation (PI) treatments is given. ► Generic PI treatments in use today are discussed. ► Suggestions for future research are presented. ► A dose of 250 Gy for most insects may suffice.

    The present invention provides methods, computer readable media, and apparatuses for a generic robot architecture providing a framework that is easily portable to a variety of robot platforms and is configured to provide hardware abstractions, abstractions for generic robot attributes, environment abstractions, and robot behaviors. The generic robot architecture includes a hardware abstraction level and a robot abstraction level. The hardware abstraction level is configured for developing hardware abstractions that define, monitor, and control hardware modules available on a robot platform. The robot abstraction level is configured for defining robot attributes and provides a software framework for building robot behaviors from the robot attributes. Each of the robot attributes includes hardware information from at least one hardware abstraction. In addition, each robot attribute is configured to substantially isolate the robot behaviors from the at least one hardware abstraction.

    The NRC has recognized the need to integrate generic issues (GIs). The GI process includes a number of phases, all of which should recognize the potential for overlap and conflict among related issues. In addition to the issues themselves, other related NRC and industry programs and activities need to be factored into the GI process. Integration has taken place, or is taking place, for a number of GIs. Each case of integration involves a specific set of circumstances and, as a result, the way in which integration proceeds can vary. This paper discusses the integration of issues in the generic issue process and provides a number of examples

    The history of the development of generic phytosanitary irradiation (PI) treatments is discussed beginning with its initial proposal in 1986. Generic PI treatments in use today are 150 Gy for all hosts of Tephritidae, 250 Gy for all arthropods on mango and papaya shipped from Australia to New Zealand, 300 Gy for all arthropods on mango shipped from Australia to Malaysia, 350 Gy for all arthropods on lychee shipped from Australia to New Zealand and 400 Gy for all hosts of insects other than pupae and adult Lepidoptera shipped to the United States. Efforts to develop additional generic PI treatments and reduce the dose for the 400 Gy treatment are ongoing with a broad based 5-year, 12-nation cooperative research project coordinated by the joint Food and Agricultural Organization/International Atomic Energy Agency Program on Nuclear Techniques in Food and Agriculture. Key groups identified for further development of generic PI treatments are Lepidoptera (eggs and larvae), mealybugs and scale insects.

    Extreme sea states, which the IEC 61400-3 (2008) standard requires for the ultimate limit state (ULS) analysis of offshore wind turbines are derived to establish the design basis for the conceptual layout of deep water floating offshore wind turbine foundations in hurricane affected areas....... Especially in the initial phase of floating foundation concept development, site specific metocean data are usually not available. As the areas of interest are furthermore not covered by any design standard, in terms of design sea states, generic and in engineering terms applicable environmental background...... data is required for a type specific conceptual design. ULS conditions for different return periods are developed, which can subsequently be applied in siteindependent analysis and conceptual design.

    Full Text Available Reed Solomon (RS codes is a mechanism to detect and correct burst of errors in data transmission and storage systems. It provides a solid introduction to foundation mathematical concept of Galois Field algebra and its application. With the development of digital hardware technology, the RS concepts were brought into reality, i.e. the implementation of RS codec chips. This paper presents the development steps of a generic RS encoder using VHDL. The encoder is able to handle generic width of data, variable length of information, number of error as well as variable form of primitive polynomial and generator polynomial used in the system. The design has been implemented for FPGA chip Xilinx XC3S200-5FT256 and has a better performance than commercially available equivalent encoder.

    Background While generic drugs are therapeutically equivalent to brand drugs, some patients and healthcare providers remain uncertain about whether they produce identical outcomes. Authorized generics, which are identical in formulation to corresponding brand drugs but marketed as a generic, provide a unique post-marketing opportunity to study whether utilization patterns are influenced by perceptions of generic drugs. Objectives To compare generic-to-brand switchback rates between generics and authorized generics. Methods A retrospective cohort study was conducted using claims and electronic health records data from a regional U.S. healthcare system. Ten drugs with authorized generics and generics marketed between 1999 and 2014 were evaluated. Eligible adult patients received a brand drug during the 6 months preceding generic entry, and then switched to a generic or authorized generic. Patients in this cohort were followed for up to 30 months from the index switch date to evaluate occurrence of generic-to-brand switchbacks. Switchback rates were compared between patients on authorized generics versus generics using Kaplan-Meier curves and Cox proportional hazards models, controlling for individual drug effects, age, sex, Charlson comorbidity score, pre-index drug use characteristics, and pre-index healthcare utilization. Results Among 5,542 unique patients that switched from brand-to-generic or brand-to-authorized generic, 264 (4.8%) switched back to the brand drug. Overall switchback rates were similar for authorized generics compared with generics (HR=0.86; 95% CI 0.65-1.15). The likelihood of switchback was higher for alendronate (HR=1.64; 95% CI 1.20-2.23) and simvastatin (HR=1.81; 95% CI 1.30-2.54) and lower for amlodipine (HR=0.27; 95% CI 0.17-0.42) compared with other drugs in the cohort. Conclusions Overall switchback rates were similar between authorized generic and generic drug users, indirectly supporting similar efficacy and tolerability profiles for

    2007-03-01

    The effect of purely persuasive advertising on generic market entry and social welfare is analysed. An incumbent has the possibility to invest in advertising which affects the prescribing physician's perceived relative qualities of the brand-name and the generic version of the drug. Advertising creates product differentiation and can induce generic market entry which is deterred without differentiation due to strong Bertrand competition. However, over-investment in advertising can deter generic market entry under certain conditions and reduces welfare as compared to accommodated market entry.

    Generic drugs contain identical active ingredients as their corresponding brand drugs and are pharmaceutically equivalent and bioequivalent, whereas authorized generic drugs (AGs) contain both identical active and inactive ingredients as their corresponding brand drugs but are marketed as generics. This study compares generic-to-brand switchback rates between generic and AGs. Retrospective cohort study. Claims and electronic health record data from a regional U.S. health care system. The full cohort consisted of 5542 unique patients who received select branded drugs during the 6 months prior to their generic drug market availability (between 1999 and 2014) and then were switched to an AG or generic drug within 30 months of generic drug entry. For these patients, 5929 unique patient-drug combinations (867 with AGs and 5062 with generic drugs) were evaluated. Ten drugs with AGs and generics marketed between 1999 and 2014 were evaluated. The date of the first generic prescription was considered the index date for each drug, and it marked the beginning of follow-up to evaluate the occurrence of generic-to-brand switchback patterns over the subsequent 30 months. Switchback rates were compared between patients receiving AGs versus those receiving generics using multivariable Cox proportional hazards models, controlling for individual drug effects, age, sex, Charlson Comorbidity Score, pre-index drug use characteristics, and pre-index health care utilization. Among the 5542 unique patients who switched from brand to generic or brand to AG, 264 (4.8%) switched back to the brand drug. Overall switchback rates were similar for AGs compared with generics (hazard ratio [HR] 0.86, 95% confidence interval [CI] 0.65-1.15). The likelihood of switchback was higher for alendronate (HR 1.64, 95% CI 1.20-2.23) and simvastatin (HR 1.81, 95% CI 1.30-2.54) and lower for amlodipine (HR 0.27, 95% CI 0.17-0.42) compared with the other drugs evaluated.

    Key findings. (1) Zero copayment for generic drugs is the greatest influencer of generic statin utilization. (2) Both higher copayments for generic drugs and lower copayments for competing brands are associated with a decreased probability of using generic statins. (3) Prior authorization and step therapy requirements for brand-name statins are associated with an increased use of generic drugs. (4) Greater use of generic statins should reduce costs for patients, plans, and Medicare.

    2005-06-01

    As there is general disagreement about the way generic medicines should be commercialized, two retailing policies are analyzed, taking into account their effects on the welfare of patients, government, pharmacies and physicians. In the first policy scenario, pharmacies are allowed to substitute generic medicines for branded ones, while in the second, substitution is forbidden. In both cases a pharmacies association is allowed to have a share in the production of generic medicines. The model predicts that under some conditions patients may prefer substitution by pharmacies but when doctors' decisions are binding, they are never "excessively bad". However, the policy choice belongs to the government, which prefers to allow for substitution more often than patients would like.

    We study a binary mixture of Bose-Einstein condensates, confined in a generic potential, in the Thomas-Fermi approximation. We search for the zero-temperature ground state of the system, both in the case of fixed numbers of particles and fixed chemical potentials. For generic potentials, we analyze the transition from mixed to separated ground-state configurations as the inter-species interaction increases. We derive a simple formula that enables one to determine the location of the domain walls. Finally, we find criteria for the energetic stability of separated configurations, depending on the number and the position of the domain walls separating the two species. (paper)

  4. Generic evolution of mixing in heterogeneous media

    Science.gov (United States)

    De Dreuzy, J.; Carrera, J.; Dentz, M.; Le Borgne, T.

    2011-12-01

    Mixing in heterogeneous media results from the competition bewteen flow fluctuations and local scale diffusion. Flow fluctuations quickly create concentration contrasts and thus heterogeneity of the concentration field, which is slowly homogenized by local scale diffusion. Mixing first deviates from Gaussian mixing, which represents the potential mixing induced by spreading before approaching it. This deviation fundamentally expresses the evolution of the interaction between spreading and local scale diffusion. We characterize it by the ratio γ of the non-Gaussian to the Gaussian mixing states. We define the Gaussian mixing state as the integrated squared concentration of the Gaussian plume that has the same longitudinal dispersion as the real plume. The non-Gaussian mixing state is the difference between the overall mixing state defined as the integrated squared concentration and the Gaussian mixing state. The main advantage of this definition is to use the full knowledge previously acquired on dispersion for characterizing mixing even when the solute concentration field is highly non Gaussian. Using high precision numerical simulations, we show that γ quickly increases, peaks and slowly decreases. γ can be derived from two scales characterizing spreading and local mixing, at least for large flux-weighted solute injection conditions into classically log-normal Gaussian correlated permeability fields. The spreading scale is directly related to the longitudinal dispersion. The local mixing scale is the largest scale over which solute concentrations can be considered locally uniform. More generally, beyond the characteristics of its maximum, γ turns out to have a highly generic scaling form. Its fast increase and slow decrease depend neither on the heterogeneity level, nor on the ratio of diffusion to advection, nor on the injection conditions. They might even not depend on the particularities of the flow fields as the same generic features also prevail for

    2015-09-01

    The definition and reuse of generic software architecture for launchers is not so usual for several reasons: the number of European launcher families is very small (Ariane 5 and Vega for these last decades); the real time constraints (reactivity and determinism needs) are very hard; low levels of versatility are required (implying often an ad hoc development of the launcher mission). In comparison, satellites are often built on a generic platform made up of reusable hardware building blocks (processors, star-trackers, gyroscopes, etc.) and reusable software building blocks (middleware, TM/TC, On Board Control Procedure, etc.). If some of these reasons are still valid (e.g. the limited number of development), the increase of the available CPU power makes today an approach based on a generic time triggered middleware (ensuring the full determinism of the system) and a centralised mission and vehicle management (offering more flexibility in the design and facilitating the long term maintenance) achievable. This paper presents an example of generic software architecture which could be envisaged for future launchers, based on the previously described principles and supported by model driven engineering and automatic code generation.

    We perform a model-independent analysis of kinetically driven inflation (KDI) which (partially) includes generalized G-inflation and ghost inflation. We evaluate the background evolution splitting into the inflationary attractor and the perturbation around it. We also consider the quantum fluctuation of the scalar mode with a usual scaling and derive the spectral index, ignoring the contribution from the second-order products of slow-roll parameters. Using these formalisms, we find that within our generic framework the models of KDI which possess the shift symmetry of scalar field cannot create the quantum fluctuation consistent with the observation. Breaking the shift symmetry, we obtain a few essential conditions for viable models of KDI associated with the graceful exit.

    Full Text Available This article provides insights into proactive safety management and mitigation. An analysis of accident reports reveals categories of supervening causes of accidents which can be directly linked to the concept of generic competencies (information management, communication and coordination, problem solving, and effect control. These findings strongly suggest adding the human element as another safety-constituting pillar to the concept of ship safety next to technology and regulation. We argue that the human element has unique abilities in dealing with critical and highly dynamic situations which can contribute to the system's recovery from non-routine or critical situations. By educating seafarers in generic competencies we claim to enable the people onboard to successfully deal with critical situations.

  15. Automated analysis in generic groups

    Science.gov (United States)

    Fagerholm, Edvard

    This thesis studies automated methods for analyzing hardness assumptions in generic group models, following ideas of symbolic cryptography. We define a broad class of generic and symbolic group models for different settings---symmetric or asymmetric (leveled) k-linear groups --- and prove ''computational soundness'' theorems for the symbolic models. Based on this result, we formulate a master theorem that relates the hardness of an assumption to solving problems in polynomial algebra. We systematically analyze these problems identifying different classes of assumptions and obtain decidability and undecidability results. Then, we develop automated procedures for verifying the conditions of our master theorems, and thus the validity of hardness assumptions in generic group models. The concrete outcome is an automated tool, the Generic Group Analyzer, which takes as input the statement of an assumption, and outputs either a proof of its generic hardness or shows an algebraic attack against the assumption. Structure-preserving signatures are signature schemes defined over bilinear groups in which messages, public keys and signatures are group elements, and the verification algorithm consists of evaluating ''pairing-product equations''. Recent work on structure-preserving signatures studies optimality of these schemes in terms of the number of group elements needed in the verification key and the signature, and the number of pairing-product equations in the verification algorithm. While the size of keys and signatures is crucial for many applications, another aspect of performance is the time it takes to verify a signature. The most expensive operation during verification is the computation of pairings. However, the concrete number of pairings is not captured by the number of pairing-product equations considered in earlier work. We consider the question of what is the minimal number of pairing computations needed to verify structure-preserving signatures. We build an

    Absorption, metabolism, and tissue distribution studies were conducted in the rat with 14 C-biphenyl ring-labeled Direct Blue 15, a 3,3'-dimethoxybenzidine (DiMxBzd) based azo dye; Direct Red 2, based on 3,3'-dimethylbenzidine (DiMeBzd) and the corresponding benzidine congener amines. Single oral doses of the 14 C-labeled dyes (12 mg/kg, 62 micro Ci/kg) and molar equivalent doses of the respective amines were administered and urine and fecal samples collected at intervals up to 192 hours. Urine and fecal samples were analyzed for 14 C content. Most of the 14 C present in the urine could not be extracted with benzene nor chloroform, indicating high polarity. Distribution studies conducted with both dyes showed that liver, kidney, and lung accumulated and retained higher levels of 14 C than other tissues (at 72 hrs). Peak levels of 14 C, which occurred 8-12 hours after dosing, were significantly higher with Direct Red 2 than Direct Blue 15. Tissue distribution data (72 hr) for rats dosed with the free amines compared with the dyes showed a generally lower but similar distribution pattern

    A generic reference case for disposal of spent nuclear fuel and high-level radioactive waste in crystalline rock is outlined. The generic cases are intended to support development of disposal system modeling capability by establishing relevant baseline conditions and parameters. Establishment of a generic reference case requires that the emplacement concept, waste inventory, waste form, waste package, backfill/buffer properties, EBS failure scenarios, host rock properties, and biosphere be specified. The focus in this report is on those elements that are unique to crystalline disposal, especially the geosphere representation. Three emplacement concepts are suggested for further analyses: a waste packages containing 4 PWR assemblies emplaced in boreholes in the floors of tunnels (KBS-3 concept), a 12-assembly waste package emplaced in tunnels, and a 32-assembly dual purpose canister emplaced in tunnels. In addition, three failure scenarios were suggested for future use: a nominal scenario involving corrosion of the waste package in the tunnel emplacement concepts, a manufacturing defect scenario applicable to the KBS-3 concept, and a disruptive glaciation scenario applicable to both emplacement concepts. The computational approaches required to analyze EBS failure and transport processes in a crystalline rock repository are similar to those of argillite/shale, with the most significant difference being that the EBS in a crystalline rock repository will likely experience highly heterogeneous flow rates, which should be represented in the model. The computational approaches required to analyze radionuclide transport in the natural system are very different because of the highly channelized nature of fracture flow. Computational workflows tailored to crystalline rock based on discrete transport pathways extracted from discrete fracture network models are recommended.

    Today, numerous simulation and analysis codes exist for the design, commission, and operation of accelerator beam lines. There is a need to develop a common user interface and database link to run these codes interactively. This paper will describe a proposed system, GLAD (Generic LAttice Debugger), to fulfill this need. Specifically, GLAD can be used to find errors in beam lines during commissioning, control beam parameters during operation, and design beam line optics and error correction systems for the next generation of linear accelerators and storage rings.

    The generic nuclear medicine imager, whether a gamma camera, single photon emission computed tomography (SPECT) system or positron emission tomography (PET) scanner, comprises several main components: a detection system, a form of collimation to select γ rays at specific angles, electronics and a computing system to create the map of the radiotracer distribution. This section discusses these components in more detail. The first stage of a generic nuclear medicine imager is the detection of the γ rays emitted by the radionuclide. In the case of PET, the radiation of interest are the 511 keV annihilation photons that result from the interaction of the positron emitted by the radionuclide with an electron in the tissue. For general nuclear medicine and SPECT, there is one or sometimes more than one γ ray of interest, with energies in the range of <100 to >400 keV. The γ rays are detected when they interact and deposit energy in the crystal(s) of the imaging system. There are two main types of detector: crystals that give off light that can be converted to an electrical signal when the γ ray interacts (‘scintillators’) and semiconductors, crystals that generate an electrical signal directly when the γ ray deposits energy in the crystal. Scintillation detectors include NaI(Tl), bismuth germanate (BGO) and lutetium oxyorthosilicate (LSO); semiconductor detectors used in nuclear medicine imagers include cadmium zinc telluride (CZT). Radiation detectors are described in more detail in Chapter 6.

    This report presents the priority rankings for generic safety issues related to nuclear power plants. The purpose of these rankings is to assist in the timely and efficient allocation of NRC resources for the resolution of those safety issues that have a significant potential for reducing risk. The report focuses on the prioritization of generic safety issues. Issues primarily concerned with the licensing process or environmental protection and not directly related to safety have been excluded from prioritization. The prioritized issues include: TMI Action Plan items under development; previously proposed issues covered by Task Action Plans, except issues designated at Unresolved Safety Issues (USIs) which had already been assigned high priority; and newly-proposed issues. Future supplements to this report will include the prioritization of additional issues. The safety priority rankings are HIGH, MEDIUM, LOW, and DROP and have been assigned on the basis of risk significance estimates, the ratio of risk to costs and other impacts estimated to result if resolutions of the safety issues were implemented, and the consideration of uncertainties and other quantitative or qualitative factors. To the extent practical, estimates are quantitative

    This report is a manual for providing information required to use a special computer program developed by the NRC for indexing generic communications. The program is written in a user-friendly menu driven form using dBASE III programming language. It facilitates use of the required dBASE III search and sort capabilities to access records in a database called Generic Communications Index. This index is made up of one record each for all bulletins, circulars, and information notices, including revisions and supplements, from 1971, when such documentation started, through 1986 (or to the latest update). The program is designed for use by anyone modestly acquainted with the general use of IBM-compatible personal computers. The manual contains both a brief overview and a detailed description of the program, as well as detailed instructions for getting started using the program on a personal computer with either a two-floppy disk or a hard disk system. Included at the end are a brief description of how to handle problems which might occur, and notes on the makeup of the program and database files for help in adding records of communications for future years

    Generic drugs have the same active substance, the same pharmaceutical form, the same therapeutic indications and a similar bioequivalence with the reference medicinal product (branded). Although a similar efficacy is postulated, some cases of clinical inefficacy during treatment with generic formulations have been reported. In this case, we describe a woman with onychomycosis that developed a skin rash during treatment with a generic formulation of itraconazole. Drug administration and its re-challenge confirmed the association between itraconazole and skin rash. Both Naranjo probability scale and World Health Organization causality assessment scale documented a probable association between generic-itraconazole and skin rash. The switch from generic formulation to brand one induced an improvement of symptoms. Since we are unable to evaluate the role of each excipient in the development of skin rash, we cannot rule out their involvement. However, more data are necessary to better define the similarities or differences between branded and generic formulations.

    The Health (Pricing and Supply of Medical Goods) Act 2013 passed into law in July 2013 and legislated for generic substitution in Ireland. The aim of the study was to ascertain the knowledge and perceptions of stakeholders i.e. patients, pharmacists and prescribers, of generic medicines and to generic substitution with the passing of legislation. Three stakeholder specific questionnaires were developed to assess knowledge of and perceptions to generic medicines and generic substitution. Purposive samples of patients, prescribers and pharmacists were analysed. Descriptive quantitative and qualitative analyses were undertaken. A total of 762 healthcare professionals and 353 patients were recruited. The study highlighted that over 84% of patients were familiar with generic medicines and are supportive of the concept of generic substitution. Approximately 74% of prescribers and 84% of pharmacists were supportive of generic substitution in most cases. The main areas of concern highlighted by the healthcare professionals that might impact on the successful implementation of the policy, were the issue of bioequivalence with generic medicines, the computer software systems used at present in general practitioner (GP) surgeries and the availability of branded generics. The findings from this study identify a high baseline rate of acceptance to generic medicines and generic substitution among patients, prescribers and pharmacists in the Irish setting. The concerns of the main stakeholders provide a valuable insight into the potential difficulties that may arise in its implementation, and the need for on-going reassurance and proactive dissemination of the impact of the generic substitution policy. The existing positive attitude to generic medicines and generic substitution among key stakeholders in Ireland to generic substitution, combined with appropriate support and collaboration should result in the desired increase in rates of prescribing, dispensing and use of generic

    Full Text Available Abstract Background Since generic drugs have the same therapeutic effect as the original formulation but at generally lower costs, their use should be more heavily promoted. However, a considerable number of barriers to their wider use have been observed in many countries. The present study examines the influence of patients, physicians and certain characteristics of the generics' market on generic substitution in Switzerland. Methods We used reimbursement claims' data submitted to a large health insurer by insured individuals living in one of Switzerland's three linguistic regions during 2003. All dispensed drugs studied here were substitutable. The outcome (use of a generic or not was modelled by logistic regression, adjusted for patients' characteristics (gender, age, treatment complexity, substitution groups and with several variables describing reimbursement incentives (deductible, co-payments and the generics' market (prices, packaging, co-branded original, number of available generics, etc.. Results The overall generics' substitution rate for 173,212 dispensed prescriptions was 31%, though this varied considerably across cantons. Poor health status (older patients, complex treatments was associated with lower generic use. Higher rates were associated with higher out-of-pocket costs, greater price differences between the original and the generic, and with the number of generics on the market, while reformulation and repackaging were associated with lower rates. The substitution rate was 13% lower among hospital physicians. The adoption of the prescribing practices of the canton with the highest substitution rate would increase substitution in other cantons to as much as 26%. Conclusions Patient health status explained a part of the reluctance to substitute an original formulation by a generic. Economic incentives were efficient, but with a moderate global effect. The huge interregional differences indicated that prescribing behaviours and

    2012-01-01

    We consider generalized chameleon models where the conformal coupling between matter and gravitational geometries is not only a function of the chameleon field φ, but also of its derivatives via higher order co-ordinate invariants (such as ∂ μ φ∂ μ φ,□φ,...). Specifically we consider the first such non-trivial conformal factor A(φ,∂ μ φ∂ μ φ). The associated phenomenology is investigated and we show that such theories have a new generic mass-altering mechanism, potentially assisting the generation of a sufficiently large chameleon mass in dense environments. The most general effective potential is derived for such derivative chameleon setups and explicit examples are given. Interestingly this points us to the existence of a purely derivative chameleon protected by a shift symmetry for φ → φ+c. We also discuss potential ghost-like instabilities associated with mass-lifting mechanisms and find another, mass-lowering and instability-free, branch of solutions. This suggests that, barring fine-tuning, stable derivative models are in fact typically anti-chameleons that suppress the field's mass in dense environments. Furthermore we investigate modifications to the thin-shell regime and prove a no-go theorem for chameleon effects in non-conformal geometries of the disformal type

    Full Text Available Abstract Background Many efforts have been recently devoted to design, investigate and synthesize biocompatible, biodegradable polymers for applications in medicine for either the fabrication of biodegradable devices or as drug delivery systems. Many of them consist of condensation of polymers having incorporated peptide linkages susceptible to enzymatic cleavage. Polyamides (PAs containing α-amino acid residues such as L-leucine, L-alanine and L-phenylalanine have been reported as biodegradable materials. Furthermore, polyamides (PAs derived from C10 and C14 dicarboxylic acids and amide-diamines derived from 1,6-hexanediamine or 1,12-dodecanediamine and L-phenylalanine, L-valyl-L-phenylalanine or L-phenylalanyl-L-valine residues have been reported as biocompatible polymers. We have previously described the synthesis and thermal properties of a new type of polyamides-containing amino acids based on eight new symmetric meta-oriented protected diamines derived from coupling of amino acids namely; Fomc-glycine, Fmoc-alanine, Fomc-valine and Fomc-leucine with m-phenylene diamine or 2,6-diaminopyridine. Results revealed that incorporation of pyridine onto the polymeric backbone of all series decreases the thermal stability. Here we describe another family of polyamides based on benzene dicarboxylic acid, pyridine dicarboxylic acid, and α-amino acid linked to benzidine and 4,4′-oxydianiline to study the effect of the dicarboxylic acid as well as the amino acids on the nature and thermal stability of the polymers. Results We report here the preparation of a new type of polyamides based on benzene dicarboxylic acid, pyridine dicarboxylic acid, and α-amino acid linked to benzidine and 4,4′-oxydianiline to study the effect of the dicarboxylic acid as well as the amino acids on the nature and thermal stability of polymers.

    Some public scepticism exists about generics in terms of whether brand and generic drugs produce identical outcomes. This study explores whether adverse event (AE) reporting patterns are similar between brand and generic drugs, using authorized generics (AGs) as a control for possible generic drug perception biases. Events reported to the FDA Adverse Event Reporting System from the years 2004-2015 were analysed. Drugs were classified as brand, AG or generic based on drug and manufacturer names. Reports were included if amlodipine, losartan, metoprolol extended release (ER) or simvastatin were listed as primary or secondary suspect drugs. Disproportionality analyses using the reporting odds ratio (ROR) assessed the relative rate of reporting labelled AEs compared to reporting these AEs with all other drugs. The Breslow-Day test compared RORs across brand, AG and generic. Interrupted time series analysis evaluated the impact of generic entry on reporting trends. Generics accounted for significant percentages of total U.S. reports, but AGs accounted for smaller percentages of reports, including for amlodipine (14.26%), losartan (1.48%), metoprolol ER (0.35%) and simvastatin (0.70%). Whereas the RORs were significantly different for multiple brand vs generic comparisons, the AG vs generic comparisons yielded fewer statistically significant findings. Namely, only the ROR for AG differed from generic for amlodipine with peripheral oedema (P brand and generic compared with AG and generic. Use of AGs as a control for perception biases against generics is useful, but this approach can be limited by small AG report numbers.

    In this article we analyze the responses of 1220 Spanish physicians who participated in a survery about generic drugs. A previously validated questionnaire was sent to physicians through the Spanish Medical Councils of the different provinces. Four items were analyzed: what doctors know about generic drugs (knowledge); physicians' prescribing habits concerning these drugs (attitude and professional competence); how prescription of generic drugs effects pharmaceutical costs amd, finally, what doctors believe a generic drug should be. The influence of physician-related variables (age, type of contract, specialty, workload, etc.) on prescribing of generic drugs was also analyzed. In view of the results, we believe that to rationalize expenditure through and appropriate policy on generic drugs Spanish health authorities should offer more and better training and information (clear and independent) about what generic drugs are.

  1. Generic Local Hamiltonians are Gapless

    Movassagh, Ramis

    2017-12-01

    We prove that generic quantum local Hamiltonians are gapless. In fact, we prove that there is a continuous density of states above the ground state. The Hamiltonian can be on a lattice in any spatial dimension or on a graph with a bounded maximum vertex degree. The type of interactions allowed for include translational invariance in a disorder (i.e., probabilistic) sense with some assumptions on the local distributions. Examples include many-body localization and random spin models. We calculate the scaling of the gap with the system's size when the local terms are distributed according to a Gaussian β orthogonal random matrix ensemble. As a corollary, there exist finite size partitions with respect to which the ground state is arbitrarily close to a product state. When the local eigenvalue distribution is discrete, in addition to the lack of an energy gap in the limit, we prove that the ground state has finite size degeneracies. The proofs are simple and constructive. This work excludes the important class of truly translationally invariant Hamiltonians where the local terms are all equal.

    Generic physical protection logic trees, designed for application to nuclear facilities and materials, are presented together with a method of qualitative evaluation of the trees for design and analysis of physical protection systems. One or more defense zones are defined where adversaries interact with the physical protection system. Logic trees that are needed to describe the possible scenarios within a defense zone are selected. Elements of a postulated or existing physical protection system are tagged to the primary events of the logic tree. The likelihood of adversary success in overcoming these elements is evaluated on a binary, yes/no basis. The effect of these evaluations is propagated through the logic of each tree to determine whether the adversary is likely to accomplish the end event of the tree. The physical protection system must be highly likely to overcome the adversary before he accomplishes his objective. The evaluation must be conducted for all significant states of the site. Deficiencies uncovered become inputs to redesign and further analysis, closing the loop on the design/analysis cycle

  4. Generic theory for channel sinuosity.

    Lazarus, Eli D; Constantine, José Antonio

    2013-05-21

    Sinuous patterns traced by fluid flows are a ubiquitous feature of physical landscapes on Earth, Mars, the volcanic floodplains of the Moon and Venus, and other planetary bodies. Typically discussed as a consequence of migration processes in meandering rivers, sinuosity is also expressed in channel types that show little or no indication of meandering. Sinuosity is sometimes described as "inherited" from a preexisting morphology, which still does not explain where the inherited sinuosity came from. For a phenomenon so universal as sinuosity, existing models of channelized flows do not explain the occurrence of sinuosity in the full variety of settings in which it manifests, or how sinuosity may originate. Here we present a generic theory for sinuous flow patterns in landscapes. Using observations from nature and a numerical model of flow routing, we propose that flow resistance (representing landscape roughness attributable to topography or vegetation density) relative to surface slope exerts a fundamental control on channel sinuosity that is effectively independent of internal flow dynamics. Resistance-dominated surfaces produce channels with higher sinuosity than those of slope-dominated surfaces because increased resistance impedes downslope flow. Not limited to rivers, the hypothesis we explore pertains to sinuosity as a geomorphic pattern. The explanation we propose is inclusive enough to account for a wide variety of sinuous channel types in nature, and can serve as an analytical tool for determining the sinuosity a landscape might support.

    The adversaries studied were found to be complex, often unpredictable, and dynamic. The adversary typically goes through a complex decision-making process between the time a potential target is identified and the moment the decision to act is made. This study analyzes the adversary characteristics, and the following conclusions are made: one of the least likely methods of attack is an overt armed assault. Terrorists and psychotics depend upon a high degree of personal dedication. No single generic adversary group or individual exhibits strength in every characteristic. Physical danger appears to have some deterrent effect on all adversaries except the psychotics. Organized and professional criminals often try to recruit insiders. Disoriented persons, white-collar criminals, and disgruntled employees tend to operate as insiders. Professional criminals, many terrorist groups, some extremist protest groups, and certain disoriented persons plan carefully before initiating a criminal mission. Organized crime and miscellaneous criminal adversaries rely on deception and ruse to bypass security. After the decision to commit a crime, the resources deployed by terrorists or organized criminals will be a function of their perception of the operational requirements of the crime. The nature of ''threat'' is dynamic; adversary behavior and capability appear to be related to prevailing political, economic, and social conditions

  6. Bridging generic and professional care practices for Muslim patients through use of Leininger's culture care modes.

    2008-04-01

    The purpose of this article is to provide knowledge of traditional Muslim generic (folk) care beliefs, expressions and practices derived from research and descriptive sources, in order to assist nurses and other health care professionals to integrate generic (folk) into professional care practices. Muslim generic (folk) care beliefs and practices related to the caregiving process, health, illness, dietary needs, dress, privacy, modesty, touch, gender relations, eye contact, abortion, contraception, birth, death and bereavement were explored. A discussion involving the use of Leininger's culture care preservation and/or maintenance, culture care accommodation and/or negotiation and culture care repatterning and/or restructuring action modes to bridge the gap between generic (folk) and professional (etic) care practices and to consequently promote culturally congruent care is presented.

    The first generic tacrolimus product gained Food and Drug Administration approval in August 2009. This prospective, observational trial sought to determine the need for dose titrations and measure drug cost savings on conversion to generic tacrolimus. Transplant recipients on stable tacrolimus doses were converted from brand to generic tacrolimus on a mg:mg basis. Data were collected at the time of generic conversion (study arm) and at a time point exactly 6 months before conversion (control arm) for all subjects. Seventy conversions from four centers are reported. Subjects were a mean of 70 months after kidney (n=37), liver (n=28), or multiorgan (n=5) transplant. In the study arm, mean tacrolimus doses were 4.4 and 4.5 mg/d and mean tacrolimus trough concentrations were 5.8 and 5.9 ng/mL before and after conversion, respectively. In the control arm, mean tacrolimus doses were 4.6 and 4.6 mg/d and mean tacrolimus trough concentrations were 6.1 and 5.9 ng/mL before and after the control time point, respectively. Dose titrations occurred in five patients (7%) in the control arm and 15 patients (21%) in the study arm (P=0.028). Mean monthly drug costs were $645 for brand, $593 for generic, and $595 for generic after dose titrations. Mean monthly patient copays were $38 for brand and $15 for generic. These cumulative data show that dose requirements and trough levels are similar between brand and generic tacrolimus and that generic substitution allows for savings. However, postconversion monitoring is prudent as patients may require dose titration.

    In this article, we investigate the penetration of generic selective serotonin reuptake inhibitors (SSRIs) in the US market and the implications for patient out-of-pocket expense. The data suggest that generic penetration into the SSRI market has grown from approximately nine percent in 2000, the year that the patent for Prozac((R)) expired, to 72 percent in 2007. For December, 2007, the difference in patient out-of-pocket expense for branded vs. generic agents was, on average, $55.42 for patients paying by cash (i.e., they had no prescription drug insurance) and $22.39 for patients with insurance coverage.

  13. Brand and generic medications: Are they interchangeable

    International Nuclear Information System (INIS)

    Al-Jazairi, Abdulrazak S.; Blhareth, S.; Eqtefan, Iyad S.; Al-Suwayeh, Saleh A.

    2008-01-01

    Generic substitution has become a common practice since the late 1970s in the United States. At that time, many of these generics caused bioavailability problems, which fueled suspicions about their efficacy and safety and the Food and Drug Administration (FDA) standards for bioequivalence. In Saudi Arabia, the increasing number of local products raised several concerns with regard to switching from brands to generics. Our objective was to review and examine the basis of the controversy surrounding brand and generic interchangeability and to explore a practical approach in pursuing a switch. Articles indexed initially under terms such as generic medications, generic substitution, bioequivalence and bioinequivalence were identified. These terms were used to search the indexing service, MEDLINE (1966-2006). References from the extracted articles and additional data sources, including the Code of Federal Regulations and Regulatory Guidelines from the FDA Center for Drug Evaluation and research were also reviewed. Foe most drugs, bioequivalence testing generally should enable clinicians to routinely substitute generic for innovator products. However, for narrow therapeutic, critical dose drugs, or for highly variable drugs, safe switching between products can not be assured. These drugs need special precautions and blood level monitoring upon switching. FDA firmly believes that approved generic and brand drugs can be dispensed with the full expectation that the consumer will receive the same clinical benefit. Performing the switch process is an advisable practice to reduce health care costs in countries with strong post-marketing surveillance program, but caution is to be exercised when narrow therapeutic index drugs or highly variable drugs are prescribed.

  14. Generic medicine and prescribing: A quick assessment

    Directory of Open Access Journals (Sweden)

    2017-01-01

    Full Text Available Generic drugs are copies of brand-name drugs that have exactly the same dosage, intended use, effects, side effects, route of administration, risks, safety, and strength as the original drug. In other words, their pharmacological effects are exactly the same as those of their brand-name counterparts. The Food and Drug Administration (FDA describes that generic drugs are essential possibilities that allow better access to healthcare for all Americans. They are replicas of brand-name drugs and are the identical as those of brand-name drugs in dosage form, safety, strength, route of administration, quality, performance features, and anticipated to use. Healthcare authorities and users can be guaranteed that FDA-approved generic drug products have met the same stiff principles as the innovator drug. The company that made Bayer aspirin fought in court enthusiastically to keep generic versions off the shelves, in the 1920s. The company lost in court, and consumers suddenly had an array of choices in generic aspirin. The Supreme Court of India uttering ‘the Supreme Court's ruling will prevent companies from further seeking unwarranted patents on HIV and other essential medicines.’ Generic medicine cannot be sold at a price higher than the branded medicine, so it is regularly a low-priced option. Thereafter, both the end user and the government who pay for part of the price of the medicine under the Pharmaceutical Benefits Scheme in Australia are benefitted. The treatment of diseases using essential drugs, prescribed by their generic names, has been emphasised by the WHO and many national health policies. Although there are some improvements in generic medicine prescribing, it has been advised by the WHO that ‘countries should intensify efforts to measure and regularly monitor medicine prices and availability, and adopt policy measures to address the issues identified.’

  15. Sharing, samples, and generics: an antitrust framework.

    Science.gov (United States)

    Carrier, Michael A

    Rising drug prices are in the news. By increasing price, drug companies have placed vital, even life-saving, medicines out of the reach of consumers. In a recent development, brand firms have prevented generics even from entering the market. The ruse for this strategy involves risk-management programs known as Risk Evaluation and Mitigation Strategies ("REMS"). Pursuant to legislation enacted in 2007, the FDA requires REMS when a drug's risks (such as death or injury) outweigh its rewards. Brands have used this regime, intended to bring drugs to the market, to block generic competition. Regulations such as the federal Hatch-Waxman Act and state substitution laws foster widespread generic competition. But these regimes can only be effectuated through generic entry. And that entry can take place only if a generic can use a brand's sample to show that its product is equivalent. More than 100 generic firms have complained that they have not been able to access needed samples. One study of 40 drugs subject to restricted access programs found that generics' inability to enter cost more than $5 billion a year. Brand firms have contended that antitrust law does not compel them to deal with their competitors and have highlighted concerns related to safety and product liability in justifying their refusals. This Article rebuts these claims. It highlights the importance of samples in the regulatory regime and the FDA's inability to address the issue. It shows how a sharing requirement in this setting is consistent with Supreme Court caselaw. And it demonstrates that the brands' behavior fails the defendant-friendly "no economic sense" test because the conduct literally makes no sense other than by harming generics. Brands' denial of samples offers a textbook case of monopolization. In the universe of pharmaceutical antitrust behavior, other conduct--such as "pay for delay" settlements between brands and generics and "product hopping" from one drug to a slightly modified

    This paper presents a way to use the ICRP approach for protection of the environment in generic assessments of the radiological impact of radioactive releases to the marine environment. Generic assessments of radiological impact to the environment are needed in certain circumstances, for example, when input data are limited or when the likely radiological consequences are expected to be not significant. Under these circumstances the effort in performing the assessment must be commensurate with the potential radiological consequences. The generic assessment described in this paper is a simple tool which provides reasonable and cautious results and is applicable to multiple exposure scenarios associated with the assessment of the radiological impact of releases to the marine the environment. This generic assessment can be also used to provide preliminary results which, when compared to radiological criteria, may determine the need of further specific assessments. The ICRP based its approach to protect the environment in the definition of a set of reference animals and plants and the use of related radiological criteria, in the form of derived consideration reference levels. The paper discusses selection and exposure conditions of the reference animals and plants, methods to estimate their doses and the use of the radiological criteria, for the purpose of a generic assessment. The IAEA is elaborating applications of these generic impact assessments presented in the paper to be included in international guidance under development. (authors)

    The list of generic medicines (LGM), published since 1997 by the Agence Française de Sécurité Sanitaire des Produits de Santé (AFFSSaPS), the French Medicine Agency, concerns a special part of the medicines reimbursed by the National Health Insurance (Social Security). The objectives of the present study were: i) to describe the components of this list, based on pharmaceutical, economical and therapeutic characteristics, ii) to study differences between generic and reference products (formulations, excipients, prices, etc.), iii) to analyze information on excipients provided to health care professionals. The 21st version of the LGM (April 2001) was used. Therapeutic value was retrieved from the 2001 AFSSaPS report on the therapeutic value of 4490 reimbursed medicines. Information on excipients in the LGM and the Vidal dictionary (reference prescription book in France) was compared. The products included in the LGM represent 20% of all reimbursed medicines. The mean price differences between generics and their reference products vary between 30 and 50% for more than two thirds of the generic groups. The therapeutic value of the products of the LGM was judged important in 71% of cases (vs 63% for the 4409 assessed medicines) and insufficient in 13% of cases (vs 19%). Information on excipients is often missing and sometimes erroneous. Although the LGM is regularly revised and thus the generic market in perpetual change, the 2001 cross description of this pharmaceutical market provides much informations and raises some concern.

    Science.gov (United States)

    Elliott, R

    2000-01-01

    On 17 March 2000, the World Trade Organization upheld the provision in Canada's patent laws that allows generic drug manufacturers to develop (but not sell) their cheaper versions of patented medicines before the 20-year patients expire. The decision prevents pharmaceutical companies from enjoying market monopolies beyond their patent terms, avoiding what would otherwise be even lengthier delays in the sale of cheaper, generic drugs in Canada. This decision is of significance not only to Canada, but also to other WTO member countries and to all individuals who use pharmaceutical products. However, the decision is not all positive: the WTO also ruled that Canada is violating international agreements by letting generic manufacturers stockpile their versions of patented drugs before patents expire. This article explains the issues, the arguments, and the decision.

  5. Benefits of Digital Equipment Generic Qualification Activities

    International Nuclear Information System (INIS)

    Thomas, James E.; Steiman, Samuel C.

    2002-01-01

    As a result of nuclear power plant instrumentation and control obsolescence issues, there have been numerous activities during recent years relating to the qualification of digital equipment. Some of these activities have been 'generic' in nature in that the qualification was not limited to plant specific applications, but was intended to cover a broad base of potential applications of the digital equipment. These generic qualifications have been funded by equipment manufacturers and by utility groups and organizations. The generic activities sponsored by the Electric Power Research Institute (EPRI) have been pilot projects for an overall generic qualification approach. The primary benefit resulting from the generic qualification work to date is that a number of digital platforms and digital devices are now available for use in various nuclear safety-related applications. Many of the tests and evaluations necessary to support plant specific applications have been completed. The amount of data and documentation that each utility must develop on a case by case basis has been significantly reduced. There are also a number of additional benefits resulting from these industry efforts. The challenges and difficulties in qualifying digital equipment for safety-related applications are now more clearly understood. EPRI has published a lessons learned document (EPRI Report 1001452, Generic Qualification of Commercial Grade Digital Devices: Lessons Learned from Initial Pilots, which covers several different qualification areas, including device selection, project planning, vendor surveys and design reviews, and electromagnetic compatibility (EMC) qualification. Application of the experience and lessons learned from the EPRI pilot activities should help reduce the effort and cost required for future qualification work. Most generic qualification activities for commercial equipment have been conducted using the approach of EPRI TR-106439, Guideline on Evaluation and Acceptance

    Cañadillas-Hidalgo, F M; Sánchez-Alvarez, J C; Serrano-Castro, P J; Mercadé-Cerdá, J M

    Pharmaceutical spending in Spain accounts for 1.2-1.4% of the gross domestic product and is increasing by 5-12% per year. One of the measures adopted by the government to cut this spending is the possible substitution of original prescribed drugs by generics. In the case of antiepileptic drugs (AED), which are characterised by a scant therapeutic margin, these steps have sparked a scientific debate about their repercussion on the control of epileptic patients. We propose to draw up a set of implicit evidence-based consensus practice guidelines concerning issues related with this topic. A selective search for quality scientific information on the subject was conducted on PubMed-Medline, Tripdatabase and the Biblioteca Cochrane Plus. The selected references were analysed and discussed by the authors, and the recommendations deriving from them were collected. A total of 21 primary documents and 16 practice guidelines, protocols or experts' recommendations were identified. Our recommendations were explicitly included at the end of the text. The Andalusian Epilepsy Society makes the following recommendations: 1) not replacing an innovative AED by its generic in a controlled patient; 2) beginning treatment with a generic AED in monotherapy or in association is acceptable; 3) not exchanging generic AED from different pharmaceutical companies; 4) explaining to the patient the rules governing the authorization of generics and the importance of avoiding exchanges between different generic AED; and 5) if there is some worsening of the clinical condition or side effects appear following the introduction of a generic, the causes must be investigated and communicated to the bodies responsible for pharmacovigilance.

    Brian Bevins; Yves Roblin

    2003-01-01

    The Generic Lock system is a software framework that allows highly flexible feedback control of large distributed systems. It allows system operators to implement new feedback loops between arbitrary process variables quickly and with no disturbance to the underlying control system. Several different types of feedback loops are provided and more are being added. This paper describes the further evolution of the system since it was first presented at ICALEPCS 2001 and reports on two years of successful use in accelerator operations. The framework has been enhanced in several key ways. Multiple-input, multiple-output (MIMO) lock types have been added for accelerator orbit and energy stabilization. The general purpose Proportional-Integral-Derivative (PID) locks can now be tuned automatically. The generic lock server now makes use of the Proxy IOC (PIOC) developed at Jefferson Lab to allow the locks to be monitored from any EPICS Channel Access aware client. (Previously clients had to be Cdev aware.) The dependency on the Qt XML parser has been replaced with the freely available Xerces DOM parser from the Apache project

    We consider exploration algorithms of the random sequential adsorption type both for homogeneous random graphs and random geometric graphs based on spatial Poisson processes. At each step, a vertex of the graph becomes active and its neighboring nodes become blocked. Given an initial number of vertices N growing to infinity, we study statistical properties of the proportion of explored (active or blocked) nodes in time using scaling limits. We obtain exact limits for homogeneous graphs and prove an explicit central limit theorem for the final proportion of active nodes, known as the jamming constant, through a diffusion approximation for the exploration process which can be described as a unidimensional process. We then focus on bounding the trajectories of such exploration processes on random geometric graphs, i.e., random sequential adsorption. As opposed to exploration processes on homogeneous random graphs, these do not allow for such a dimensional reduction. Instead we derive a fundamental relationship between the number of explored nodes and the discovered volume in the spatial process, and we obtain generic bounds for the fluid limit and jamming constant: bounds that are independent of the dimension of space and the detailed shape of the volume associated to the discovered node. Lastly, using coupling techinques, we give trajectorial interpretations of the generic bounds.

    All companies have at their core a vast amount of similar equipment that would benefit from solid preventive maintenance (PM) recommendations that are generic and easily adapted to meet operational conditions. The re-emergence of PM optimization methods like Reliability Centered Maintenance, further illustrates that companies in all industries recognize the positive influence that a well-focused maintenance program has on the corporate bottom line. The Electric Power Research Institute (EPRI) has long been a leader in providing universally adaptable maintenance solutions to meet the evolving needs of its membership. Nearly ten years ago, EPRI began developing the PM Basis Database, a one-of-a-kind repository of PM recommendations for basic infrastructure components (such as pumps, motors, valves, compressors), derived from equipment experts. EPRI has now made available this comprehensive body of knowledge to all industries. This paper will explore the origins and structure of the database, how these generic PM recommendations benefit every industry, and how they may be obtained. (author)

    2010-03-01

    In this article, we explore the penetration of generic atypical antipsychotics in the United States market before and after the availability of generic risperidone in July 2008. Analysis suggests that, overall, generic penetration into the atypical antipsychotic market has grown from approximately three percent in January 2008 to more than 25 percent in December 2009. Similar trends are uncovered when branded and generic prescriptions are analyzed by specialty.

    Generic noun phrases (e.g., "Cats like to drink milk") are a primary means by which adults express generalizations to children, yet they pose a challenging induction puzzle for learners. Although prior research has established that English speakers understand and produce generic noun phrases by preschool age, little is known regarding the cross-cultural generality of generic acquisition. Southern Peruvian Quechua provides a valuable comparison because, unlike English, it is a highly inflected language in which generics are marked by the absence rather than the presence of any linguistic markers. Moreover, Quechua is spoken in a cultural context that differs markedly from the highly educated, middle-class contexts within which earlier research on generics was conducted. We presented participants from 5 age groups (3-6, 7-9, 10-12, 14-35, and 36-90 years of age) with two tasks that examined the ability to distinguish generic from non-generic utterances. In Study 1, even the youngest children understood generics as applying broadly to a category (like "all") and distinct from indefinite reference ("some"). However, there was a developmental lag before children understood that generics, unlike "all", can include exceptions. Study 2 revealed that generic interpretations are more frequent for utterances that (a) lack specifying markers and (b) are animate. Altogether, generic interpretations are found among the youngest participants, and may be a default mode of quantification. These data demonstrate the cross-cultural importance of generic information in linguistic expression.

    The protection provided by patents on medicines has a limited duration. The expiry of patents expiration allows copies of the drugs to be released, competing with original. At first, they were identical to the original, known as generic drugs, but in recent years, due to the marketing of biological therapies and the expiry of many of their patents, biosimilar drugs have also emerged. These are not exact copies of the original, but, like generic drugs, biosimilar drugs have to demonstrate equivalence to the reference drugs in quality, safety and efficacy. Nevertheless, despite their importance and contribution to sustainability of health system, doctors are sometimes unaware of differences between them, and their impact in terms of clinical and economic effects. An attempt is made to review and clarify certain aspects often unknown by physicians, despite their involvement in their use. Copyright © 2015 SECA. Published by Elsevier Espana.

    Full Text Available Religious texts have been examined by scholars from different theoretical standpoints. However, a close survey of the literature reveals that little attention has been paid to Christian apologetics from a linguistic perspective. Also, an examination of studies along the lines of Generic Structure Potential (henceforth GSP shows that the genre status of Christian apologetics has not been indicated. This gap provides the motivation for this paper, which investigates the GSP of Christian apologetics. Twenty texts written by various key contemporary apologetic writers were purposively selected for the study. The following generic structure potential catalogue was generated:The paper reveals that the elements of the GSP concertedly work to advance, argue for or defend the Christian belief system. The paper also suggests that the model could be applied to other forms of apologetic instances.

  15. Generic Sensor Failure Modeling for Cooperative Systems

    Science.gov (United States)

    Jäger, Georg; Zug, Sebastian

    2018-01-01

    The advent of cooperative systems entails a dynamic composition of their components. As this contrasts current, statically composed systems, new approaches for maintaining their safety are required. In that endeavor, we propose an integration step that evaluates the failure model of shared information in relation to an application’s fault tolerance and thereby promises maintainability of such system’s safety. However, it also poses new requirements on failure models, which are not fulfilled by state-of-the-art approaches. Consequently, this work presents a mathematically defined generic failure model as well as a processing chain for automatically extracting such failure models from empirical data. By examining data of an Sharp GP2D12 distance sensor, we show that the generic failure model not only fulfills the predefined requirements, but also models failure characteristics appropriately when compared to traditional techniques.

    This paper presents a generic approach developed to derive surface reflectance over land from a variety of sensors. This technique builds on the extensive dataset acquired by the Terra platform by combining MODIS and MISR to derive an explicit and dynamic map of band ratio's between blue and red channels and is a refinement of the operational approach used for MODIS and LANDSAT over the past 15 years. We will present the generic approach and the application to MODIS and LANDSAT data and its validation using the AERONET data.

  18. U.S. NRC's generic issues program

    International Nuclear Information System (INIS)

    Kauffman, J.V.; Foster, J.W.

    2008-01-01

    The United States Nuclear Regulatory Commission (NRC) has a Generic Issues Program (GIP) to address Generic Issues (GI). A GI is defined as 'a regulatory matter involving the design, construction, operation, or decommissioning of several, or a class of, NRC licensees or certificate holders that is not sufficiently addressed by existing rules, guidance, or programs'. This rather legalistic definition has several practical corollaries: First, a GI must involve safety. Second, the issue must involve at least two plants, or it would be a plant-specific issue rather than a GI. Third, the potential safety question must not be covered by existing regulations and guidance (compliance). Thus, the effect of a GI is to potentially change the body of regulations and associated guidance (e.g., regulatory guides). The GIP was started in 1976, thus it is a relatively mature program. Approximately 850 issues have been processed by the program to date. More importantly, even after 30 years, new GIs continue to be proposed. The entire set of Generic Issues (GIs) is updated annually in NUREG-0933, 'A Prioritization of Generic Safety Issues'. GIs normally involve complex questions of safety and regulation. Efficient and effective means of addressing these issues are very important for regulatory effectiveness. If an issue proves to pose a genuine, significant safety question, then swift, effective, enforceable, and cost-effective action needs to be taken. Conversely, if an issue is of little safety significance, the issue should be dismissed in an expeditious manner, avoiding unnecessary expenditure of resources and regulatory burden or uncertainty. This paper provides a summary of the 5-stage program, from identification through the regulatory assessment stage. The paper also includes a discussion of the program's seven criteria, sources of proposed GIs, recent improvements, publicly available information, historical performance, and status of current GIs.

    2000-01-01

    This report describes the results of a project to improve the generic component failure database for the Savannah River Site (SRS). Additionally, guidelines were developed further for more advanced applications of database values. A representative list of components and failure modes for SRS risk models was generated by reviewing existing safety analyses and component failure data bases and from suggestions from SRS safety analysts. Then sources of data or failure rate estimates were identified and reviewed for applicability. A major source of information was the Nuclear Computerized Library for Assessing Reactor Reliability, or NUCLARR. This source includes an extensive collection of failure data and failure rate estimates for commercial nuclear power plants. A recent Idaho National Engineering Laboratory report on failure data from the Idaho Chemical Processing Plant was also reviewed. From these and other recent sources, failure data and failure rate estimates were collected for the components and failure modes of interest. For each component failure mode, this information was aggregated to obtain a recommended generic failure rate distribution (mean and error factor based on a lognormal distribution). Results are presented in a table in this report. A major difference between generic database and previous efforts is that this effort estimates failure rates based on actual data (failure events) rather than on existing failure rate estimates. This effort was successful in that over 75% of the results are now based on actual data. Also included is a section on guidelines for more advanced applications of failure rate data. This report describes the results of a project to improve the generic component failure database for the Savannah River site (SRS). Additionally, guidelines were developed further for more advanced applications of database values

  3. Generic superweak chaos induced by Hall effect

    Science.gov (United States)

    Ben-Harush, Moti; Dana, Itzhack

    2016-05-01

    We introduce and study the "kicked Hall system" (KHS), i.e., charged particles periodically kicked in the presence of uniform magnetic (B ) and electric (E ) fields that are perpendicular to each other and to the kicking direction. We show that for resonant values of B and E and in the weak-chaos regime of sufficiently small nonintegrability parameter κ (the kicking strength), there exists a generic family of periodic kicking potentials for which the Hall effect from B and E significantly suppresses the weak chaos, replacing it by "superweak" chaos (SWC). This means that the system behaves as if the kicking strength were κ2 rather than κ . For E =0 , SWC is known to be a classical fingerprint of quantum antiresonance, but it occurs under much less generic conditions, in particular only for very special kicking potentials. Manifestations of SWC are a decrease in the instability of periodic orbits and a narrowing of the chaotic layers, relative to the ordinary weak-chaos case. Also, for global SWC, taking place on an infinite "stochastic web" in phase space, the chaotic diffusion on the web is much slower than the weak-chaos one. Thus, the Hall effect can be relatively stabilizing for small κ . In some special cases, the effect is shown to cause ballistic motion for almost all parameter values. The generic global SWC on stochastic webs in the KHS appears to be the two-dimensional closest analog to the Arnol'd web in higher dimensional systems.

  4. Generic legislation of new psychoactive drugs.

    2013-03-01

    New psychoactive drugs (NPDs, new psychoactive substances) enter the market all the time. However, it takes several months to ban these NPDs and immediate action is generally not possible. Several European countries and drug enforcement officers insist on a faster procedure to ban NPDs. Introduction of generic legislation, in which clusters of psychotropic drugs are banned in advance, has been mentioned as a possible solution. Here we discuss the pros and cons of such an approach. First, generic legislation could unintentionally increase the expenditures of enforcement, black market practices, administrative burden and health risks for users. Second, it may have a negative impact on research and the development of new treatments. Third, due to the complexity of generic legislation, problems in the enforcement are anticipated due to lack of knowledge about the chemical nomenclature. Finally, various legal options are already available to ban the use, sale and trade of NPDs. We therefore conclude that the currently used scientific benefit-risk evaluation should be continued to limit the adverse health effects of NPDs. Only in emergency cases, where fatal incidents (may) occur, should this approach be overruled.

  5. Generic programming for deterministic neutron transport codes

    International Nuclear Information System (INIS)

    Plagne, L.; Poncot, A.

    2005-01-01

    This paper discusses the implementation of neutron transport codes via generic programming techniques. Two different Boltzmann equation approximations have been implemented, namely the Sn and SPn methods. This implementation experiment shows that generic programming allows us to improve maintainability and readability of source codes with no performance penalties compared to classical approaches. In the present implementation, matrices and vectors as well as linear algebra algorithms are treated separately from the rest of source code and gathered in a tool library called 'Generic Linear Algebra Solver System' (GLASS). Such a code architecture, based on a linear algebra library, allows us to separate the three different scientific fields involved in transport codes design: numerical analysis, reactor physics and computer science. Our library handles matrices with optional storage policies and thus applies both to Sn code, where the matrix elements are computed on the fly, and to SPn code where stored matrices are used. Thus, using GLASS allows us to share a large fraction of source code between Sn and SPn implementations. Moreover, the GLASS high level of abstraction allows the writing of numerical algorithms in a form which is very close to their textbook descriptions. Hence the GLASS algorithms collection, disconnected from computer science considerations (e.g. storage policy), is very easy to read, to maintain and to extend. (authors)

    BACKGROUND: Generic substitution means that one medicinal product is replaced by another product containing the same active substance. It is strictly regulated with respect to its bioequivalence, and all products must have undergone appropriate studies. Although generic substitution is widely...... implemented, it still remains to be answered how generic switch influences persistence to long-term treatment, and if it is modified by patients' concerns about medicine and views on generic medicine. This study focuses on users of antidepressants and antiepileptics, and their experience of generic switching....... METHODS: The study was an observational cohort study. By use of a prescription database, we identified patients who had redeemed prescriptions on generically substitutable drugs, and a questionnaire was mailed to them. We analyzed predictors of discontinuation in relation to generic switch and patients...

    2011-01-01

    With the aim of optimizing the regulatory effort in Argentina, the Nuclear Regulatory Authority (ARN) evaluated two worldwide concepts used in the radioactive waste management field: “Generic Exemption Levels” and “Generic Clearance Levels”. The objective of this paper is to present the progress made in the past two years in relation to these topics and to present the results of the specific requests received from users of radioactive material. Since the approval of both Generic Levels, the ARN received two exemption requests. The first one, regarding the practice of dismantling lighting rods with 241 Am. The other case regards the international trade, distribution, usage and final disposal of lighting products with radioactive material ( 85 Kr and 232 Th). Concerning clearance, there has not been any request yet. However, in the future the ARN expects to receive this kind of requests from nuclear power plants and other facilities related to the nuclear fuel cycle. (authors) [es

    Over the last several years, profile data from nine different tokamaks have been stored in the magnetic fusion energy database (MFEDB). These data sets have come from a variety of sources and most are given in different coordinate systems. In order to attempt any intermachine analysis, it is convenient to transform these data sets into one generic coordinate system and to choose a uniform set of variable names. The authors describe the data sets from each tokamak indicating the source of the data and the coordinate system in which it is given. Next, they discuss the generic coordinate that has been adopted and show how it is implemented for each tokamak. Finally, the generic naming convention that has been adopted is discussed. It follows closely that which was used by Christiansen et al. for the ITER Global Energy Confinement H-Mode Database. For further clarification, they discuss the characteristics of the magnetic geometry given a Fourier representation of the magnetic equilibria

    Generic medicines offer an opportunity for governments to contain pharmaceutical expenditures, since generics are generally 10%-80% lower in price than brand medicines. Belgium has a small generic market that takes up 15% of the total pharmaceutical market in packages sold. To determine the knowledge of consumers about the different available packages of a common over-the-counter medicine (acetaminophen) with regard to price advantage, quality, and effectiveness in a country with a small generic market. We conducted an online survey in the general Flemish population using a questionnaire with 25 statements. The questionnaire also contained 2 informative interventions. First, we showed the price per package and per tablet that the patient would pay in the pharmacy. Second, we provided the respondent with general information about generic medication (equivalence, effectiveness, price, and recognition). Before and after the interventions, we probed for preferences and knowledge about the different packages. Multivariate logistic models were used to examine the independent effects of consumer characteristics on responses to the survey statements. We obtained a sample of 1,636 respondents. The general attitude towards generic medication was positive-only 5% would rather not use a generic. Nevertheless, only 17% of the respondents were able to recognize a generic medicine. Older consumers (aged 60 years and above) were more often confused about the different packages (OR = 2.59, 95% CI = 1.76-3.80, P ≤ 0.001). Consumers without a higher education degree tended to be more doubtful about the difference in effectiveness and quality between the different brands (OR = 0.59, 95% CI = 0.44-0.79, P ≤ 0.001). Consumer recognition of the name of the active substance of acetaminophen was poor. When different brands were displayed, possible price advantage seemed to be an important motive to switch to a cheaper brand. Consumers generally found medicines

    Full Text Available Bioequivalence (BE has always been an important pharmaceutical area, particularly (but not solely in Mediterranean region, where the use of generic drugs is a relatively recent development. The lack of new therapeutic molecules has concentrated primary research in the hands of a few large pharmaceutical companies. For smaller companies, this has created opportunities for the development of new formulations of existing drugs (orodispersible tablets that dissolve in the mouth, extended-release tablets, transdermal delivery systems, generic drugs. These applications take advantage of the Abridged New Drug Application (ANDA procedure, which exempts them from a series of expensive investigations and limits the requirement for clinical testing to bioequivalence trials. Since 1991, bioequivalence trials have been regulated by US Food and Drug Administration (FDA and European Medicines Agency (EMA guidelines that provide precise indications on the most specific procedures to be adopted. In spite of these guidelines, however, some aspects of the process have not been fully defined, the most important of which regards the management of endogenous substances. Additional problems are how to manage bioequivalence protocols with drugs that have long half-lives and those whose clearance is characterized by high intrinsic variability. The view that bioequivalence data would be more reliable if they were based on studies in target populations is a myth to be discredited. The present paper reviews issues relative to pharmacokinetics (PK, bioavailability (BA, and bioequivalence, also from an historical viewpoint, and includes a stimulating “questions and answers” section on some key aspects of the bioequivalence of generic drugs.

  12. Might generic OCs create contraceptive price war?

    Science.gov (United States)

    1987-02-01

    Genora 1/35 and 1/50, the 1st generic oral contraceptives (OCs) in the world, are now being marketed in the US. Clinicians interviewed by "Contraceptive Technology Update" (CTU) offer differing opinions as to what this new OC may mean in the marketplace. Products of Rugby Laboratories, the pills are copy products of Ortho Pharmaceutical's ON 1/35 and ON 1/50 formulations. Most clinicians believe that Genora's success or failure in the OC market depends on its eventual retail price. The price difference of $3-$4 may be sufficiently substantial for retailers to charge less for the generic OCs. If that is the case, many doctors may prescribe a pill which will save their patients $4/month. Dr. Mildred Hanson, a Minneapolis gynecologist/obstetrician, feels any cost savings from Genora will have a significant impact on the OC market. She suggests that the less expensive OCs will catch the attention of health maintenance organizations (HMOs) and the business of women who participate in such health plans. Yet James Burns, director of family planning services for the Hartford City Health Department, thinks that even a full-scale retail price war won't have much effect from a clinic standpoint. He reports that clinics are able to obtain contraceptive supplies rather inexpensively through the contracting system. Hanson also expressed doubt over the potential popularity of Genora 1/50 as clinical concerns about the effects of combined OCs on serum lipid levels and carbohydrate metabolism have resulted in a nationwide push toward OCs containing less than 50 micrograms of estrogen. He indicated concern that declines in pharmaceutical house products from pricing competition with generic pills might have a negative impact on contraceptive research and development. Dick Haskitt, director of business planning for Syntex Laboratories, Inc., who will produce the OCs for Rugby, reports that their market research shows that people are very interested in having a generic OC available

    A variety of computer manufacturers' equipment monitors plant systems in Northeast Utilities' (NU) nuclear and fossil power plants. The hardware configuration and the application software in each of these systems are essentially one of a kind. Over the next few years these computer systems will be replaced by the NU Generic System, whose prototype is under development now for Millstone III, an 1150 Mwe Pressurized Water Reactor plant being constructed in Waterford, Connecticut. This paper discusses the Millstone III computer system design, concentrating on the special problems inherent in a distributed system configuration such as this. (auth)

    The wing-body aerodynamics data base consists of a series of CFD (Computational Fluid Dynamics) simulations about a generic wing body configuration consisting of a ogive-circular-cylinder fuselage and a simple symmetric wing mid-mounted on the fuselage. Solutions have been obtained for Nonlinear Potential (P), Euler (E) and Navier-Stokes (N) solvers over a range of subsonic and transonic Mach numbers and angles of attack. In addition, each solution has been computed on a series of grids, coarse, medium and fine to permit an assessment of grid refinement errors.

  15. Specialization of Generic Array Accesses After Inlining

    Full Text Available We have implemented an optimization that specializes type-generic array accesses after inlining of polymorphic functions in the native-code OCaml compiler. Polymorphic array operations (read and write in OCaml require runtime type dispatch because of ad hoc memory representations of integer and float arrays. It cannot be removed even after being monomorphized by inlining because the intermediate language is mostly untyped. We therefore extended it with explicit type application like System F (while keeping implicit type abstraction by means of unique identifiers for type variables. Our optimization has achieved up to 21% speed-up of numerical programs.

  16. Entry decisions in the generic pharmaceutical industry.

    Morton, F M

    1999-01-01

    Data on all generic drug entries in the period 1984-1994 are used to estimate which markets heterogeneous potential entrants will decide to enter. I find that organizational experience predicts entry. Firms tend to enter markets with supply and demand characteristics similar to the firm's existing drugs. Larger revenue markets, markets with more hospital sales, and products that treat chronic conditions attract more entry. The simultaneous nature of entry leads to an additional interpretation: specialization is profitable because of the severe risk to profits when a market is "overentered." However, I am unable to make any conclusions about the efficiency of entry decisions.

    We propose a generic optical network design for future avionic systems in order to reduce the weight and power consumption of current networks on board. A three-layered network structure over a ring optical network topology is suggested, as it can provide full reconfiguration flexibility...... and support a wide range of avionic applications. Segregation can be made on different hierarchies according to system criticality and security requirements. The structure of each layer is discussed in detail. Two network configurations are presented, focusing on how to support different network services...... by such a network. Finally, three redundancy scenarios are discussed and compared....

    Let (Mn , g , X) be a complete generic shrinking Ricci soliton of dimension n ≥ 3. In this paper, by employing curvature inequalities, the formula of X-Laplacian for the norm square of the trace-free curvature tensor, the weak maximum principle and the estimate of the scalar curvature of (Mn , g) , we prove some rigidity results for (Mn , g , X) . In particular, it is showed that (Mn , g , X) is isometric to Rn or a finite quotient of Sn under a pointwise pinching condition. Moreover, we establish several optimal inequalities and classify those shrinking solitons for equalities.

    With an increase in prescription drug spending and rising drug costs there is a need to encourage the use of generic prescription drugs. However, maximizing generic drug use is not possible without the public's positive perception and meeting their informational needs about generic drugs. Thus, improving the public's confidence in, and knowledge of generic drugs on the market is critical. The objective of this systematic review is to examine and evaluate the studies focusing on the nature and extent of key factors influencing generic drug use in the United States in order to help guide policy, education and practice interventions. Using multiple search engines and key word screening criteria, empirical studies published in English between January 1, 2005 and December 31, 2015 were identified. A qualitative synthesis of the evidence identified domains of key factors that influenced generic drug use across studies. Over 3000 citations met the key word screening criteria; 67 of these met inclusion criteria for the systematic review. Seven domains of factors that influence generic drug utilization were identified: 1) patient-related factors, 2) formulary management or cost containment, 3) healthcare policies, 4) promotional activities, 5) educational initiatives, 6) technology, and 7) physician-related factors. Patients, physicians, pharmacists, formulary managers, and policymakers play an important role in generic drug use. Understanding the factors influencing generic drug use can help guide future policy, education, and practice interventions to increase generic drug use. Copyright © 2017 Elsevier Inc.

    Simion, G.; Sciacca, F.; Claiborne, E.; Watlington, B.; Riordan, B.; McLaughlin, M.

    1988-05-01

    This report represents a validation study of the cost methodologies and quantitative factors derived in Labor Productivity Adjustment Factors and Generic Methodology for Estimating the Labor Cost Associated with the Removal of Hardware, Materials, and Structures From Nuclear Power Plants. This cost methodology was developed to support NRC analysts in determining generic estimates of removal, installation, and total labor costs for construction-related activities at nuclear generating stations. In addition to the validation discussion, this report reviews the generic cost analysis methodology employed. It also discusses each of the individual cost factors used in estimating the costs of physical modifications at nuclear power plants. The generic estimating approach presented uses the /open quotes/greenfield/close quotes/ or new plant construction installation costs compiled in the Energy Economic Data Base (EEDB) as a baseline. These baseline costs are then adjusted to account for labor productivity, radiation fields, learning curve effects, and impacts on ancillary systems or components. For comparisons of estimated vs actual labor costs, approximately four dozen actual cost data points (as reported by 14 nuclear utilities) were obtained. Detailed background information was collected on each individual data point to give the best understanding possible so that the labor productivity factors, removal factors, etc., could judiciously be chosen. This study concludes that cost estimates that are typically within 40% of the actual values can be generated by prudently using the methodologies and cost factors investigated herein

  4. A prioritization of generic safety issues

    1991-07-01

    This report presents the priority rankings for generic safety issues and related to nuclear power plants. The purpose of these rankings is to assist in the timely and efficient allocation of NRC resources for the resolution of those safety issues that have a significant potential for reducing risk. The report focuses on the prioritization of generic safety issues. Issues primarily concerned with the licensing process or environmental protection and not directly related to safety have been excluded from prioritization. The prioritized issues include: TMI Action Plan items under development; previously proposed issues covered by Task Action Plans, except issues designated as Un-resolved Safety Issues (USIs) which had already been assigned high priority; and newly-proposed issues. Future supplements to this report will include the prioritization of additional issues. The safety priority rankings are High, Medium, Low, and Drop and have been assigned on the basis of risk significance estimates, the ratio of risk to costs and other impacts estimated to result if resolutions of the safety issues were implemented, and the consideration of uncertainties and other quantitative or qualitative factors. To the extent practical, estimates are quantitative. 1310 refs

  5. The importance of being first: evidence from Canadian generic pharmaceuticals.

    2002-12-01

    This paper uses pooled cross-section data on Canadian ethical drug sales to examine the effect of entry timing on sales of generic drugs. The data is for all drugs for which the first generic competitor entered during the years 1994-1997. It is found that the first generic entrant has a lasting competitive advantage: being first into the market appears to lead to an increase of around 30% in market share (among generics) over a period of at least 4 years. This finding has considerable implications for the current policy of allowing brandname drug companies to issue pseudo-generic equivalents as a preemptive strike against true generic competitors.

    2010-01-01

    To evaluate the impact of generic substitution decision support on electronic (e-) prescribing of generic medications. The authors analyzed retrospective outpatient e-prescribing data from an academic medical center and affiliated network for July 1, 2005-September 30, 2008 using an interrupted time-series design to assess the rate of generic prescribing before and after implementing generic substitution decision support. To assess background secular trends, e-prescribing was compared with a concurrent random sample of hand-generated prescriptions. Proportion of generic medications prescribed before and after the intervention, evaluated over time, and compared with a sample of prescriptions generated without e-prescribing. The proportion of generic medication prescriptions increased from 32.1% to 54.2% after the intervention (22.1% increase, 95% CI 21.9% to 22.3%), with no diminution in magnitude of improvement post-intervention. In the concurrent control group, increases in proportion of generic prescriptions (29.3% to 31.4% to 37.4% in the pre-intervention, post-intervention, and end-of-study periods, respectively) were not commensurate with the intervention. There was a larger change in generic prescribing rates among authorized prescribers (24.6%) than nurses (18.5%; adjusted OR 1.38, 95% CI 1.17 to 1.63). Two years after the intervention, the proportion of generic prescribing remained significantly higher for e-prescriptions (58.1%; 95% CI 57.5% to 58.7%) than for hand-generated prescriptions ordered at the same time (37.4%; 95% CI 34.9% to 39.9%) (p<0.0001). Generic prescribing increased significantly in every specialty. Implementation of generic substitution decision support was associated with dramatic and sustained improvements in the rate of outpatient generic e-prescribing across all specialties.

    2010-09-01

    In Switzerland the site selection procedure for both high level waste (HLW) and low and intermediate level waste (L/ILW) repositories is specified by the Swiss Federal Office of Energy in the Sectoral Plan for Deep Geological Repositories. In the forthcoming stage 2 of this plan, potential sites will be identified within regions previously selected based on the presence of suitable host rocks, namely Opalinus Clay, 'Brauner Dogger', Effingen Member and Helvetic Marl. Preliminary safety analyses are an integral part of this procedure, and require, amongst other information, the radionuclide sorption properties of the host rock. This report describes a methodology to develop a Generic Rock Sorption Data Base (GR-SDB) for argillaceous rocks. The method will be used to compile specific SDBs for the above mentioned host rocks. Arguments are presented that the main factor influencing sorption on argillaceous rocks is the phyllosilicate mineral content. These minerals are particularly effective at binding metals to their surfaces by cation exchange and surface complexation. Generally, the magnitude of sorption is directly correlated with the phyllosilicate content (2:1 type clays: illite/smectite/illitesmectite mixed layers), and this parameter best reflects the sorption potential of a given mineral assembly. Consequently, sorption measurements on illite were preferably used as source data for the GR-SDB. The second component influencing radionuclide sorption is the porewater chemistry. In the present report, generic water compositions were extracted from the analytical ranges of deep ground waters in various sedimentary formations in Switzerland. In order to cover the range of ionic strength (I) and pH values of Swiss ground waters in argillaceous rocks, five types of generic water compositions were defined, combining low, intermediate and high values of ionic strength and pH. The GR-SDB for in situ conditions was derived using conversion factors (CF). As the name

    Generic drugs have a key role to play in the efficient allocation of financial resources for pharmaceutical medicines. Policies implemented in the countries with a high rate of generic drug use, such as Canada, Denmark, Germany, the Netherlands, the United Kingdom, and the United States, are reviewed, with consideration of the market structures that facilitate strong competition. Savings in these countries are realized through increases in the volume of generic drugs used and the frequently significant differences in the price between generic medicines and branded originator medicines. Their policy tools include the mix of supply-side measures and demand-side measures that are relevant for generic promotion and higher generic use. On the supply-side, key policy measures include generic drug marketing regulation that facilitates market entry soon after patent expiration, reference pricing, the pricing of branded originator products, and the degree of price competition in pharmaceutical markets. On the demand-side, measures typically encompass influencing prescribing and dispensing patterns as well as introducing a co-payment structure for consumers/patients that takes into consideration the difference in cost between branded and generic medicines. Quality of generic medicines is a pre-condition for all other measures discussed to take effect. The paper concludes by offering a list of policy options for decision-makers in Central and Eastern European economies in transition.

    There is interest in introducing generic antiretroviral drugs (ARVs) into high-income countries in order to maximise efficiency in health care budgets. Studies examining patients' and providers' knowledge and attitudes to generic substitution in HIV are few. This was a cross-sectional, observational study with a convenience sample of adult HIV-infected patients and health care providers (HCPs). Data on demographics, knowledge of generic medicine and facilitators of generic substitution were collected. Descriptive and univariate analysis was performed using SPSS V.23™. Questionnaires were completed by 66 patients. Seventy-one per cent would have no concerns with the introduction of generic ARVs. An increase in frequency of administration (61%) or pill burden (53%) would make patients less likely to accept generic ARVs. There were 30 respondents to the HCP survey. Concerns included the supply chain of generics, loss of fixed dose combinations, adherence and use of older medications. An increase in dosing frequency (76%) or an increase in pill burden (50%) would make HCPs less likely to prescribe a generic ARV. The main perceived advantage was financial. Generic substitution of ARVs would be acceptable to the majority of patients and HCPs. Reinvesting savings back into HIV services would facilitate the success of such a programme.

  12. Brand loyalty, patients and limited generic medicines uptake.

    Costa-Font, Joan; Rudisill, Caroline; Tan, Stefanie

    2014-06-01

    The sluggish development of European generic drug markets depends heavily on demand side factors, and more specifically, patients' and doctors' loyalty to branded products. Loyalty to originator drugs, to the point where originator prices rise upon generic entry has been described as the 'generics paradox'. Originator loyalty can emerge for a plethora of reasons; including costs, perceptions about quality and physician advice. We know very little about the behavioural underpinnings of brand loyalty from the consumer or patient standpoint. This paper attempts to test the extent to which patients are brand loyal by drawing upon Spain's 2002 Health Barometer survey as it includes questions about consumer acceptance of generics in a country with exceptionally low generic uptake and substitution at the time of the study. Our findings suggest that at least 13% of the population would not accept generics as substitutes to the originator. These results confirm evidence of brand loyalty for a minority. Alongside high levels of awareness of generics, we find that low cost-sharing levels explain consumer brand loyalty but their impact on acceptance of generic substitution is very small. Higher cost-sharing and exempting fewer patients from cost-sharing have the potential to encourage generic acceptance. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

  15. Analysis of generic exemption levels for radioactive material

    International Nuclear Information System (INIS)

    Bossio, Maria C.; Muniz, Carolina C.

    2007-01-01

    In essence, exemption may be considered a generic authorization granted by the regulatory body, which, once issued, releases the practice or source from the requirements that would otherwise apply, in particular, the requirements relating to notification and authorization. The exemption figures included in the Basic Safety Standards BSS 115 were derived from the scenarios postulated in the document 'Radiation Protection 65' of the Commission of the European Communities considering quantitative exemption criteria. After presenting the basic exemption criteria for limited quantities of radioactive materials this paper describes and analyses the exposure scenarios utilized, namely: 1- Normal use (workplace) scenario; 2- Accidental ( workplace) scenario; 3- Disposal (public) scenario. Each one has different exposure pathways, summing up a total of 24, covering external exposure, ingestion and inhalation. These scenarios were used to calculate both, exempted activity concentrations (Bq/g) and total activity (Bq), though in the first case exemption applies to limited masses of low concentration activity materials. For each radionuclide, the generic exemption level was derived as the more restrictive value obtained from the scenarios, that is the lowest ratio between the applicable individual dose and the dose per unit activity (Bq) or activity concentration (Bq/g). The individual dose per unit (Bq or Bq/g, as applicable) was calculated by a formula that was adjusted, for each scenario and pathway, through different parameters, such as exposure time, dosimetric factors and geometric factors. In general, the critical pathways for α emitters were inhalation of dust and aerosols in workplace for activity concentration scenario and inhalation of dust and volatiles from an accidental fire in the workplace for total activity scenario. For β emitters the critical pathways were ingestion of an object from a landfill site by a member of the public for activity concentration

    2017-01-01

    Full Text Available In recent years searchable symmetric encryption has seen a rapid increase in query expressiveness including keyword, phrase, Boolean, and fuzzy queries. With this expressiveness came increasingly complex constructions. Having these facts in mind, we present an efficient and generic searchable symmetric encryption construction for phrase queries. Our construction is straightforward to implement, and is proven secure under adaptively chosen query attacks (CQA2 in the random oracle model with an honest-but-curious adversary. To our knowledge, this is the first encrypted phrase search system that achieves CQA2 security. Moreover, we demonstrate that our document collection preprocessing algorithm allows us to extend a dynamic SSE construction so that it supports phrase queries. We also provide a compiler theorem which transforms any CQA2-secure SSE construction for keyword queries into a CQA2-secure SSE construction that supports phrase queries.

    Multi-function fingers that are able to handle multiple workpieces are crucial in improvement of a robot workcell. Design automation of multi-function fingers is highly demanded by robot industries to overcome the current iterative, time consuming and complex manual design process. However, the existing approaches for the multi-function finger design automation are unable to entirely meet the robot industries’ need. This paper proposes a generic approach for design automation of multi-function fingers. The proposed approach completely automates the design process and requires no expert skill. In addition, this approach executes the design process much faster than the current manual process. To validate the approach, multi-function fingers are successfully designed for two case studies. Further, the results are discussed and benchmarked with existing approaches.

    1993-01-01

    One relevant issue confronting the operator of a nuclear power plant is information and task overload. The goal, then, of the various developers is to improve the current situations by creating an environment where the operator can perform at optimum capacity. This is to be accomplished by providing tools and techniques which reduce operator involvement in low level tasks (freeing up time for higher level cognitive tasks) and assist in information and knowledge manipulation so that high level tasks can be performed more efficiently. This paper reviews the operational environment of nuclear plants from the viewpoint of engineering design and from the viewpoint of the operators and technical support staff. Principles are advanced for a generic operator companion. These design principles are being applied to a test case: the Point Lepreau NGS secondary side central sampling system. 6 refs., 6 figs

    Sidló, Csaba István

    Entity Resolution (ER) covers the problem of identifying distinct representations of real-world entities in heterogeneous databases. We consider the generic formulation of ER problems (GER) with exact outcome. In practice, input data usually resides in relational databases and can grow to huge volumes. Yet, typical solutions described in the literature employ standalone memory resident algorithms. In this paper we utilize facilities of standard, unmodified relational database management systems (RDBMS) to enhance the efficiency of GER algorithms. We study and revise the problem formulation, and propose practical and efficient algorithms optimized for RDBMS external memory processing. We outline a real-world scenario and demonstrate the advantage of algorithms by performing experiments on insurance customer data.

    Hobson, Allan; Kahn, David

    2007-12-01

    Dream reports were collected from normal subjects in an effort to determine the degree to which dream reports can be used to identify individual dreamers. Judges were asked to group the reports by their authors. The judges scored the reports correctly at chance levels. This finding indicated that dreams may be at least as much like each other as they are the signature of individual dreamers. Our results suggest that dream reports cannot be used to identify the individuals who produced them when identifiers like names and gender of friends and family members are removed from the dream report. In addition to using dreams to learn about an individual, we must look at dreams as telling us about important common or generic aspects of human consciousness.

    2013-12-01

    Modeling gene regulatory networks (GRNs) is an important topic in systems biology. Although there has been much work focusing on various specific systems, the generic behavior of GRNs with continuous variables is still elusive. In particular, it is not clear typically how attractors partition among the three types of orbits: steady state, periodic and chaotic, and how the dynamical properties change with network's topological characteristics. In this work, we first investigated these questions in random GRNs with different network sizes, connectivity, fraction of inhibitory links and transcription regulation rules. Then we searched for the core motifs that govern the dynamic behavior of large GRNs. We show that the stability of a random GRN is typically governed by a few embedding motifs of small sizes, and therefore can in general be understood in the context of these short motifs. Our results provide insights for the study and design of genetic networks.

  3. Generic Skills from Qur'anic Perspective

    2012-06-01

    Full Text Available Generic skills are defined as a set of skills that are directly related and needed for the working environment. Employers prefer to recruit officials who are competent in interpersonal communication, leadership skill, team work, oral and written skills. They are reluctant to employ graduates lacking certain necessary skills. This reveals the fact that there is a serious gap between the skills that are required by the employers and the skills that the graduates possess. Therefore, this research is focused on five aspects of generic skills namely; communication, team work, problem solving, lifelong learning and self-esteem. From Qur’anic perspective, the same terms have been used except minor differences in using various terms. The thematic approach is used when discussing these aspects from the Qur’an. The findings showed that the ways of effective communication are represented by terms of qawl sadid, qawl ma`ruf, qawl baligh, qawl maysur, qawl karim and qawl layyin. For collective work, ta`aruf and tafahum, as the pre-requisites, should be practiced via ta`awun and takaful. For problem solving, four methods are adapted from the Qur’an such as reflection of the past, observation, demonstration and asking questions. For lifelong learning, the establishment of learning institutions and the self-motivation of learners are two pre-requisites that should be undertaken for its accomplishment. They could be practiced through open learning system, consultation and hands-on learning. Last but not least, for personality development could be built up through physical training, spiritual training and mental training.

  4. Generic implications of ATWS events at the Salem Nuclear Power Plant: generic implications. Vol. 1

    International Nuclear Information System (INIS)

    1983-04-01

    This report is the first of two volumes. It documents the work of an interoffice, interdisciplinary NRC Task Force established to determine the generic implications of two anticipated transients without scram (ATWS) at the Salem Nuclear Power Plant, Unit 1 on February 22 and 25, 1983. A second report will document the NRC actions to be taken based on the work of the Task Force. The Task Force was established to address three questions: (1) Is there a need for prompt action for similar equipment in other facilities. (2) Are NRC and its licensees learning the sefety-management lessons, and, (3) How should the priority and content of the ATWS rule be adjusted. A number of short-term actions were taken through Bulletins and an Information Notice. Intermediate-term actions to address the generic issues will be addressed in the separate report and implemented through appropriate regulatory mechanisms

  9. Is bioavailability altered in generic versus brand anticonvulsants?

    Science.gov (United States)

    Jankovic, Slobodan M; Ignjatovic Ristic, Dragana

    2015-03-01

    Therapeutic window of anticonvulsants is not a wide one, with phenytoin being one extreme, which can be classified as a narrow therapeutic index drug, since its ratio between the least toxic and the least effective concentration is less than twofold. In order to obtain marketing authorization, a generic anticonvulsant should demonstrate relative bioequivalence with its brand-name counterpart. However, although bioequivalent, generic anticonvulsants still do not have the same bioavailability as brand-name drugs, which may lead to larger fluctuations of steady-state plasma concentrations, and sometimes to loss of seizure control if a patient is switched from brand-name to generic or from generic to generic anticonvulsant. Generic anticonvulsants are effective, safe and affordable drugs for treatment of epilepsy, and patients could be successfully treated with them from the very beginning. It is switching from brand-name to generic anticonvulsant or from one generic anticonvulsant to another that should be avoided in clinical practice, since subtle differences in bioavailability may disturb optimal degree of seizure control to which the patient was previously successfully titrated.

  10. Policies and perceptions on generic drugs: The case of Greece.

    Xanthopoulou, Sofia-Sotiria; Katsaliaki, Korina

    2018-01-01

    The increase in the consumption of generic drugs to reduce pharmaceutical expenditure is a challenge for many countries, especially during the economic crisis. The purpose of the present study is to review the Greek market of generic drugs and the decisions that shape it, to determine the factors that affect Greek patients' and doctors' attitudes about generic substitution and present a set of measures for all stakeholders based on the findings of the secondary and primary analysis. The study includes (a) an analysis of international and national reports and legislation on drugs policies and (b) a questionnaire survey of 242 hospital patients and 85 doctors regarding their perceptions on generics. A small increase in the volume of generics is recorded, yet not followed by sales value, over the recent years that the measures for promoting generics prescription took effect. Distrust from both patients and doctors was observed toward generics' effectiveness and toward the appropriateness of the regulatory authorities' quality controls. The study presents a structured set of viable measures, applicable to many countries, for promoting generic drug consumption that can lead to economic efficiency without degrading the health care quality.

  11. Generic medicines: solutions for a sustainable drug market?

    Science.gov (United States)

    Dylst, Pieter; Vulto, Arnold; Godman, Brian; Simoens, Steven

    2013-10-01

    Generic medicines offer equally high-quality treatment as originator medicines do at much lower prices. As such, they represent a considerable opportunity for authorities to obtain substantial savings. At the moment, the pharmaceutical landscape is changing and many pharmaceutical companies have altered their development and commercial strategies, combining both originator and generic divisions. In spite of this, the generic medicines industry is currently facing a number of challenges: delayed market access; the limited price differential with originator medicines; the continuous downwards pressure on prices; and the negative perception regarding generic medicines held by some key stakeholder groups. This could jeopardize the long-term sustainability of the generic manufacturing industry. Therefore, governments must focus on demand-side policies, alongside policies to accelerate market access, as the generic medicines industry will only be able to deliver competitive and sustainable prices if they are ensured a high volume. In the future, the generic medicines industry will increasingly look to biosimilars and generic versions of orphan drugs to expand their business.

  12. Generic maintenance immunosuppression in solid organ transplant recipients.

    Ensor, Christopher R; Trofe-Clark, Jennifer; Gabardi, Steven; McDevitt-Potter, Lisa M; Shullo, Michael A

    2011-11-01

    Survival after solid organ transplantation has increased in the era of tacrolimus and mycophenolate. This increased survival could be due in part to the broad clinical use of these potent and specific agents for maintenance immunosuppression. These drugs have enhanced specificity and potency for T and B lymphocytes compared with their predecessors, cyclosporine and azathioprine. Between 2008 and 2010, the United States Food and Drug Administration approved several generic formulations of both tacrolimus and mycophenolate mofetil. Deciding whether generic products can be safely substituted for the innovator product is a clinical dilemma similar to that which occurred when generic formulations of cyclosporine became available. We describe the concerns regarding generic immunosuppression use, summarize expert opinion and consensus statements in transplantation, analyze the potential impact of generic substitution, and provide estimates of populations affected based on generic drug market penetration. Formulary considerations such as cost, availability, and potential drug ordering and drug selection errors are described, and transplant coordinator and patient perspectives are reviewed. Finally, general recommendations about the use of generic maintenance immunosuppression in solid organ transplant recipients are provided. Although more research is needed to confirm clinical and therapeutic equivalence and pharmacoeconomic benefit, generic immunosuppressants can be safely substituted for innovator products as long as patients consistently receive the same product, patients and clinicians are aware of when substitutions occur, and enhanced therapeutic drug monitoring is provided during the transition.

  2. Developing competitive and sustainable Polish generic medicines market.

    Science.gov (United States)

    Simoens, Steven

    2009-10-01

    To descriptively analyze the policy environment surrounding the Polish generic medicines retail market. The policy analysis was based on an international literature review. Also, a simulation exercise was carried out to compute potential savings from substituting generic for originator medicines in Poland using IMS Health pharmaceutical intelligence data. Poland has a mature, high-volume, low-value generic medicines market, primarily driven by the establishment of the reference price at the price of the cheapest medicine in combination with pricing regulation and the low level of medicine prices. The practice of discounting in the distribution chain implies that the National Health Fund and patients do not capture the potential savings from a generic medicines market where companies compete on price. This high-volume market has benefited in the past from the limited availability of originator medicines and a short data exclusivity period, even though there are no incentives for physicians to prescribe generic medicines and a financial disincentive for pharmacists to dispense generic medicines. Increased generic substitution would be expected to reduce public expenditure on originator medicines by 21%. To develop a competitive and sustainable market, Poland needs to consider moving away from competition by discount to competition by price. This could be achieved by replacing maximum distribution margins by fixed margins. Also, Poland may wish to raise reference prices as a temporary measure to boost market entry for medicine classes with few generic medicines.

    2011-01-01

    Generics are statements such as "tigers are striped" and "ducks lay eggs". They express general, though not universal or exceptionless, claims about kinds (Carlson & Pelletier, 1995). For example, the generic "ducks lay eggs" seems true even though many ducks (e.g. the males) do not lay eggs. The universally quantified version of the statement…

    2017-08-15

    The maximum allowable size of a spherical cosmic structure as a function of its mass is determined by the maximum turn around radius R{sub TA,max}, the distance from its center where the attraction on a radial test particle due to the spherical mass is balanced with the repulsion due to the ambient dark energy. In this work, we extend the existing results in several directions. (a) We first show that, for w ≠ -1, the expression for R{sub TA,max} found earlier, using the cosmological perturbation theory, can be derived using a static geometry as well. (b) In the generic dark energy model with arbitrary time dependent state parameter w(t), taking into account the effect of inhomogeneities upon the dark energy as well, it is shown that the data constrain w(t = today) > -2.3. (c) We address the quintessence and the generalized Chaplygin gas models, both of which are shown to predict structure sizes consistent with observations. (orig.)

  5. The Impact of Information on Doctors’ Attitudes Toward Generic Drugs

    Directory of Open Access Journals (Sweden)

    Aggeliki V. Tsaprantzi MD

    2016-03-01

    Full Text Available The objective of this study is to assess the impact of information on doctors’ attitudes and perceptions toward generics. A cross-sectional survey based on a specially designed 21-item questionnaire was conducted. The survey involved doctors of different specialties working in a public hospital in Greece. The analysis includes descriptive and inferential statistics, reliability and validity tests, as well as structural equation modeling to evaluate the causal model. Statistical analysis was accomplished by using SPSS 20 and Amos 20. A total of 134 questionnaires out of 162 were received, providing a response rate of 82.71%. A number of significant associations were found between information and perceptions about generic medicines with demographic characteristics. It seems that the provision of quality information on generic drugs influences doctors’ attitudes and prescription practices toward generic drugs. This is not a static process but a rather dynamic issue involving information provision policies for strengthening the proper doctors’ attitudes toward generic drugs.

  6. Generic policy in Bulgaria: a policy of failure or success?

    Directory of Open Access Journals (Sweden)

    Assena Stoimenova

    2016-09-01

    Full Text Available Generic medicines play a key role in managing the financial resources for pharmaceuticals in every country. This study analysed the generic policy legislative framework in Bulgaria with the aim to identify whether the policy implementation can be considered successful in the light of an international review of such policies introduced in other countries, or on the contrary, it has failed to deliver the main benefits. Legislative analysis, desktop study and macroeconomic overview of the Bulgarian pharmaceutical market were included. The study showed that only 3 out of 11 important policy elements are implemented in the country. Bulgaria has one of the highest shares of generics, an average of 81.39% (volume, for the studied period (2006–2014. However, further research is needed to evaluate the success of the existing generic policy in Bulgaria, as the market share of generic drugs is not the only measure of the policy efficiency.

  7. An audit of generic prescribing in a general surgical department.

    LENUS (Irish Health Repository)

    Gleeson, M

    2013-01-17

    BACKGROUND: The Health Service Executive introduced a generic prescription policy to reduce costs. Despite this, generic prescription rates remain low. AIM: To audit in-patient prescription practice in a single surgical department and identify potential savings which could be realised by adherence to the generic prescribing policy. METHODS: Surgical in-patient charts were obtained at the point of discharge and their drug prescription information was recorded. RESULTS: 51 % of prescriptions involved a trade-name prescription where an appropriate generic equivalent existed. The cost implications for hospital and community patients were found to be greatly affected by substitution policies that exist at hospital pharmacy level. CONCLUSION: There is a need to promote greater adherence to generic prescribing amongst hospital doctors in line with international best practice. It can have a positive impact in terms of safe prescribing and can have cost implications at both hospital and community level.

  8. Generic substitution: micro evidence from register data in Norway.

    Science.gov (United States)

    Dalen, Dag Morten; Furu, Kari; Locatelli, Marilena; Strøm, Steinar

    2011-02-01

    The importance of prices, doctor and patient characteristics, and market institutions for the likelihood of choosing generic drugs instead of the more expensive original brand-name version are examined. Using an extensive dataset extracted from The Norwegian Prescription Database containing all prescriptions dispensed to individuals in February 2004 and 2006 on 23 different drugs (chemical substances) in Norway, we find strong evidence for the importance of both doctor and patient characteristics for the choice probabilities. The price difference between brand and generic versions and insurance coverage both affect generic substitution. Moreover, controlling for the retail chain affiliation of the dispensing pharmacy, we find that pharmacies play an important role in promoting generic substitution. In markets with more recent entry of generic drugs, brand-name loyalty proves to be much stronger, giving less explanatory power to our demand model.

    PURPOSE: Generic switching of warfarin was recently repealed in Denmark, as adverse drug reaction (ADR) reports suggested risk of excessive anticoagulation following switches from branded to generic warfarin. We investigated this putative association in a formalized pharmacoepidemiological analysis....... METHODS: We conducted a nationwide cohort study based on Danish healthcare registries, including data from the introduction of generic warfarin until the repeal (January 2011-April 2015). We followed Danish warfarin users over time and compared the rate of incident hospitalizations due to excessive...... anticoagulation (i.e. increased INR or any bleeding requiring hospitalization) in periods following a recent switch to generic warfarin to the rate in periods without a recent switch. RESULTS: We included 105,751 warfarin users, filling a total of 1,539,640 prescriptions for warfarin (2.5% for generic warfarin...

    Kwong, C.Y.; Djurisic, A.B.; Choy, W.C.H.; Li, D.; Xie, M.H.; Chan, W.K.; Cheah, K.W.; Lai, P.T.; Chui, P.C.

    2005-01-01

    In this work, we have investigated the material stability and organic light emitting diode (OLED) performance for tris-(8-hydroxyquinoline) aluminium (Alq 3 ) and for three of the Alq 3 derivatives. For each material, electron spin resonance (ESR) measurements were performed and the degradation of photoluminescence (PL) with atmosphere exposure was studied. Performance of OLEDs based on these materials was also studied. The device structure was ITO/N,N'-di(naphthalene-1-yl)-N,N'-diphenyl-benzidine (NPB) (50 nm)/Alq 3 or Alq 3 derivatives (60 nm)/LiF (0.3 nm)/Al (60 nm). It was found that the rate of PL decay of the films correlates strongly with the existence of ESR signal. However, stability of OLEDs fabricated from these materials showed no direct relationship with PL decay in the films. This indicates that the dominant degradation mechanism in OLEDs is related to the passage of electric current through the device. Detailed discussion of the performances of four light emitting materials in terms of efficiency and stability is given

  12. Generic Assessment Criteria for human health risk assessment of potentially contaminated land in China.

    Science.gov (United States)

    Cheng, Yuanyuan; Nathanail, Paul C

    2009-12-20

    Generic Assessment Criteria (GAC) are derived using widely applicable assumptions about the characteristics and behaviour of contaminant sources, pathways and receptors. GAC provide nationally consistent guidance, thereby saving money and time. Currently, there are no human health based Generic Assessment Criteria (GAC) for contaminated sites in China. Protection of human health is therefore difficult to ensure and demonstrate; and the lack of GAC makes it difficult to tell if there is potential significant risk to human health unless site-specific criteria are derived. This paper derived Chinese GAC (GAC) for five inorganic and eight organic substances for three regions in China for three land uses: urban residential without plant uptake, Chinese cultivated land, and commercial/industrial using the SNIFFER model. The SNIFFER model has been further implemented with a dermal absorption algorithm and the model default input values have been changed to reflect the Chinese exposure scenarios. It is envisaged that the modified SNIFFER model could be used to derive GAC for more contaminants, more Regions, and more land uses. Further research to enhance the reliability and acceptability of the GAC is needed in regional/national surveys in diet and working patterns.

    properties (parameters) used in these models are different, which not only make inter-model comparisons difficult, but also compromise the applicability of the lessons learned from one model to another model. The establishment of a reference case would therefore be helpful to set up a baseline for model development. A generic salt repository reference case was developed in Freeze et al. (2013) and the generic argillite repository reference case is presented in this report. The definition of a reference case requires the characterization of the waste inventory, waste form, waste package, repository layout, EBS backfill, host rock, and biosphere. This report mainly documents the processes in EBS bentonite and host rock that are potentially important for performance assessment and properties that are needed to describe these processes, with brief description other components such as waste inventory, waste form, waste package, repository layout, aquifer, and biosphere. A thorough description of the generic argillite repository reference case will be given in Jové Colon et al. (2014).

  14. Developing a generic environmental safety case

    International Nuclear Information System (INIS)

    Bailey, Lucy

    2014-01-01

    The Nuclear Decommissioning Authority (NDA) has been charged with implementing the United Kingdom government's policy for the long-term management of higher activity radioactive waste by planning, building and operating a geological disposal facility (GDF). Within the NDA, we - the Radioactive Waste Management Directorate (RWMD) - are tasked with the development of a GDF. The UK government has also decided that a process of voluntarism and partnership will be followed to identify a suitable site for the GDF. To date there is no volunteer community and the site selection process to find a volunteer host community is under review. RWMD has an ongoing role to provide advice to UK radioactive waste producers on the conditioning and packaging of wastes and to undertake disposability assessments of waste packaging proposals to determine their suitability for eventual disposal in a GDF. We also need to demonstrate our confidence that a GDF would be safe. Therefore RWMD has published a generic Environmental Safety Case (ESC) (NDA, 2010) to demonstrate that we are confident that a GDF could be developed to meet the guidelines set down by the environmental regulators (EA/NIEA, 2009) in a range of geological settings. The ESC includes reference case calculations that are used as a benchmark for disposability assessments. (author)

  15. Modeling generic aspects of ideal fibril formation

    Michel, D., E-mail: denis.michel@live.fr [Universite de Rennes1-IRSET, Campus de Beaulieu Bat. 13, 35042 Rennes (France)

    2016-01-21

    Many different proteins self-aggregate into insoluble fibrils growing apically by reversible addition of elementary building blocks. But beyond this common principle, the modalities of fibril formation are very disparate, with various intermediate forms which can be reshuffled by minor modifications of physico-chemical conditions or amino-acid sequences. To bypass this complexity, the multifaceted phenomenon of fibril formation is reduced here to its most elementary principles defined for a linear prototype of fibril. Selected generic features, including nucleation, elongation, and conformational recruitment, are modeled using minimalist hypotheses and tools, by separating equilibrium from kinetic aspects and in vitro from in vivo conditions. These reductionist approaches allow to bring out known and new rudiments, including the kinetic and equilibrium effects of nucleation, the dual influence of elongation on nucleation, the kinetic limitations on nucleation and fibril numbers, and the accumulation of complexes in vivo by rescue from degradation. Overlooked aspects of these processes are also pointed: the exponential distribution of fibril lengths can be recovered using various models because it is attributable to randomness only. It is also suggested that the same term “critical concentration” is used for different things, involved in either nucleation or elongation.

  16. Generic implications of the Chernobyl accident

    International Nuclear Information System (INIS)

    Sege, G.

    1989-01-01

    The US Nuclear Regulatory Commission (NRC) staff's assessment of the generic implications of the Chernobyl accident led to the conclusion that no immediate changes in the NRC's regulations regarding design or operation of US commercial reactors are needed. However, further consideration of certain issues was recommended. This paper discusses those issues and the studies being addressed to them. Although 24 tasks relating to light water reactor issues are identified in the Chernobyl follow-up research program, only four are new initiatives originating from Chernobyl implications. The remainder are limited modifications of ongoing programs designed to ensure that those programs duly reflect any lessons that may be drawn from the Chernobyl experience. The four new study tasks discussed include a study of reactivity transients, to reconfirm or bring into question the adequacy of potential reactivity accident sequences hitherto selected as a basis for design approvals; analysis of risk at low power and shutdown; a study of procedure violations; and a review of current NRC testing requirements for balance of benefits and risks. Also discussed, briefly, are adjustments to ongoing studies in the areas of operational controls, design, containment, emergency planning, and severe accident phenomena

  19. Innovation strategies for generic drug companies: moving into supergenerics.

    Science.gov (United States)

    Ross, Malcolm S F

    2010-04-01

    Pharmaceutical companies that market generic products generally are not regarded as innovators, but rather as companies that produce copies of originator products to be launched at patent expiration. However, many generics companies have developed excellent scientific innovative skills in an effort to circumvent the defense patents of originator companies. More patents per product, in terms of both drug substances (process patents and polymorph patents) and formulations, are issued to generics companies than to companies that are traditionally considered to be 'innovators'. This quantity of issued patents highlights the technical knowledge and skill sets that are available in generics companies. In order to adopt a completely innovative model (ie, the development of NCEs), a generics company would require a completely new set of skills in several fields, including a sufficient knowledge base, project and risk management experience, and capability for clinical data evaluation. However, with relatively little investment, generics companies should be able to progress into the so-called 'supergeneric' drug space - an area of innovation that reflects the existing competencies of both innovative and generics companies.

  20. Generic drug policy in Australia: a community pharmacy perspective

    2007-01-01

    This article provides a commentary, from a community pharmacy perspective, on the policy environment for the pharmacy sector in Australia, with a particular focus on present challenges arising from proposals to achieve substantial PBS cost savings from an anticipated surge of new generic drugs. Some $2 billion of medicines currently on the PBS will come off patent in the next 4 years. This growth comes from a low base where generics currently account for only 15% of the total PBS budget. Remuneration for PBS dispensing is fixed through five year agreements with the government, so trading terms on generics are important for the cross-subsidy of other dispensing activities and professional services. These trading terms (discounts provided by generics suppliers) have become part of the overall cost and revenue structure of pharmacies. Despite these arrangements, generic substitution rates in Australia are lower than in most comparable countries, which the government views as an opportunity to promote generic use. The future of generic drug supply via the PBS is important to allow consumers access to medications at the lowest possible price and to provide space for PBS listing of new and expensive drugs. But considerations of PBS reform need to take account of the role and viability of community pharmacy sector as provider of pharmaceuticals in a timely and efficient manner to Australian residents.

    To evaluate the effectiveness of four alternative interventions (member mailings, advertising campaigns, free generic drug samples to physicians, and physician financial incentives) used by a major health insurer to encourage its members to switch to generic drugs. Using claim-level data from Blue Cross Blue Shield of Michigan, we evaluated the success of four interventions implemented during 2000-2003 designed to increase the use of generic drugs among its members. Around 13 million claims involving seven important classes of drugs were used to assess the effectiveness of the interventions. For each intervention a control group was developed that most closely resembled the corresponding intervention group. Logistic regression models with interaction effects between the treatment group (intervention versus control) and the status of the intervention (active versus not active) were used to evaluate if the interventions had an effect on the generic dispensing rate (GDR). Because the mail order pharmacy was considered more aggressive at converting prescriptions to generics, separate generic purchasing models were fitted to retail and mail order claims. In secondary analyses separate models were also fitted to claims involving a new condition and claims refilled for preexisting conditions. The interventions did not appear to increase the market penetration of generic drugs for either retail or mail order claims, or for claims involving new or preexisting conditions. In addition, we found that the ratio of copayments for brand name to generic drugs had a large positive effect on the GDR. The interventions did not appear to directly influence the GDR. Financial incentives expressed to consumers through benefit designs have a large influence on their switching to generic drugs and on the less-costly mail-order mode of purchase.

    Abstract Objectives To compare rates of switchbacks to branded drug products for patients switched from branded to authorized generic drug products, which have the same active ingredients, appearance, and excipients as the branded product, with patients switched from branded to generic drug products, which have the same active ingredients as the branded product but may differ in appearance and excipients. Design Observational cohort study. Setting Private (a large commercial health plan) and public (Medicaid) insurance programs in the US. Participants Beneficiaries of a large US commercial health insurer between 2004 and 2013 (primary cohort) and Medicaid beneficiaries between 2000 and 2010 (replication cohort). Main outcome measures Patients taking branded products for one of the study drugs (alendronate tablets, amlodipine tablets, amlodipine-benazepril capsules, calcitonin salmon nasal spray, escitalopram tablets, glipizide extended release tablets, quinapril tablets, and sertraline tablets) were identified when they switched to an authorized generic or a generic drug product after the date of market entry of generic drug products. These patients were followed for switchbacks to the branded drug product in the year after their switch to an authorized generic or a generic drug product. Cox proportional hazard models were used to estimate hazard ratios and 95% confidence intervals after adjusting for demographics, including age, sex, and calendar year. Inverse variance meta-analysis was used to pool adjusted hazard ratios across all drug products. Results A total of 94 909 patients switched from branded to authorized generic drug products and 116 017 patients switched from branded to generic drug products and contributed to the switchback analysis. Unadjusted incidence rates of switchback varied across drug products, ranging from a low of 3.8 per 100 person years (for alendronate tablets) to a high of 17.8 per 100 person years (for amlodipine

    Objectives: To investigate the impact of an educational intervention on doctors’ knowledge and perceptions towards generic medicines and their generic (international non-proprietary name) prescribing practice. Methods: This is a single-cohort pre-/post-intervention pilot study. The study was conducted in a tertiary care hospital in Perak, Malaysia. All doctors from the internal medicine department were invited to participate in the educational intervention. The intervention consisted of an interactive lecture, an educational booklet and a drug list. Doctors’ knowledge and perceptions were assessed by using a validated questionnaire, while the international non-proprietary name prescribing practice was assessed by screening the prescription before and after the intervention. Results: The intervention was effective in improving doctors’ knowledge towards bioequivalence, similarity of generic medicines and safety standards required for generic medicine registration (p = 0.034, p = 0.034 and p = 0.022, respectively). In terms of perceptions towards generic medicines, no significant changes were noted (p > 0.05). Similarly, no impact on international non-proprietary name prescribing practice was observed after the intervention (p > 0.05). Conclusion: Doctors had inadequate knowledge and misconceptions about generic medicines before the intervention. Moreover, international non-proprietary name prescribing was not a common practice. However, the educational intervention was only effective in improving doctors’ knowledge of generic medicines. PMID:26770747

    The particle production in relativistic heavy-ion collisions seems to be created in a dynamically disordered system which can be best described by an extended exponential entropy. In distinguishing between the applicability of this and Boltzmann-Gibbs (BG) in generating various particle-ratios, generic (non)extensive statistics is introduced to the hadron resonance gas model. Accordingly, the degree of (non)extensivity is determined by the possible modifications in the phase space. Both BG extensivity and Tsallis nonextensivity are included as very special cases defined by specific values of the equivalence classes (c, d). We found that the particle ratios at energies ranging between 3.8 and 2760 GeV are best reproduced by nonextensive statistics, where c and d range between ˜ 0.9 and ˜ 1 . The present work aims at illustrating that the proposed approach is well capable to manifest the statistical nature of the system on interest. We don't aim at highlighting deeper physical insights. In other words, while the resulting nonextensivity is neither BG nor Tsallis, the freezeout parameters are found very compatible with BG and accordingly with the well-known freezeout phase-diagram, which is in an excellent agreement with recent lattice calculations. We conclude that the particle production is nonextensive but should not necessarily be accompanied by a radical change in the intensive or extensive thermodynamic quantities, such as internal energy and temperature. Only, the two critical exponents defining the equivalence classes (c, d) are the physical parameters characterizing the (non)extensivity.

    To allow for a conservative, simple, uniform, consistent, efficient radiation safety design for all SSRL beamlines, a generic approach has been developed, considering both synchrotron radiation (SR) and gas bremsstrahlung (GB) hazards. To develop the methodology and rules needed for generic beamline design, analytic models, the STAC8 code, and the FLUKA Monte Carlo code were used to pre-calculate sets of curves and tables that can be looked up for each beamline safety design. Conservative beam parameters and standard targets and geometries were used in the calculations. This paper presents the SPEAR3 beamline parameters that were considered in the design, the safety design considerations, and the main pre-calculated results that are needed for generic shielding design. In the end, the rules and practices for generic SSRL beamline design are summarized.

    2015-05-01

    The overall success of organ transplantation in the 21st century has been predicated, in part, on the use of newer, more potent, and selective immunosuppressive agents. However, the high cost of lifelong immunosuppression represents a financial burden for many patients. In the past 15 years, regulatory agencies in Europe and America have approved several generic immunosuppressants. One concern is whether the conversion between innovator and generic immunosuppressants will prove to be problematic. This manuscript aims to compare and contrast the bioequivalence requirements among regulatory authorities in the USA, Europe, and Canada, evaluate published studies of generic immunosuppressants in transplant recipients, summarize consensus statements made by transplant organizations and discuss how to engage patients in discussion regarding the choice between innovator and generic immunosuppressants.

    By definition a product identified by its official chemical name rather than an advertised brand name is called a generic. If a drug exert its pharmacological effects at the same site, have the same potency, same dosage form and same bioavailability as a brand name, reference listed drug (RLD), is considered as a generic. However inactive ingredients can differ between brand name and generic. It is through the regulations of the FDA that the generics gained many ground in the drug market, they currently account to more than 42% of the total prescription in the USA. These regulations include the abbreviated new drug application (ANDA) for the registration process and drug substitution at the pharmacy level without patient or physician consent. This coupled with a keen interest of third party payers and the health authorities to reduce the high transplant health budget (over 2 Billion US $) made it a necessity to introduce the generics into the field of transplantation. Using the above mentioned definition we can theoretically say that all anti-lymphocytes, produced in the same animal species, are generic of each. Moreover, monoclonal antibodies that are directed against the same target and have the same bioavailability are also consider generics to each other. Of all the immunosuppressive drugs that have been introduced into the field of transplantation none has been as dominant as Cyclosporine. Cyclosporine became and still is the backbone for any immunosuppressive protocol. In the year 1992, Consupren, the first, non-FDA approved, generic to Sandimmun was introduced. Although Consupren was not bioequivalent to Neoral, however, long-term results in kidney transplantation have been similar for both drugs. The introduction of Consupren resulted in a near 40% reduction in the total cost of immunosuppressive therapy. Interestingly the cost of the brand name drug Neoral was also reduced by 20%. The cost reduction allowed the introduction of the new immunosuppressive

  18. The short-term impact of Ontario's generic pricing reforms.

    Full Text Available Canadians pay amongst the highest generic drug prices in the world. In July 2010, the province of Ontario enacted a policy that halved reimbursement for generic drugs from the public drug plan, and substantially lowered prices for private purchases. We quantified the impact of this policy on overall generic drug expenditures in the province, and projected the impact in other provinces had they mimicked this pricing change.We used quarterly prescription generic drug dispensing data from the IMS-Brogan CompuScript Audit. We used the price per unit in both the pre- and post-policy period and two economics price indexes to estimate the expenditure reduction in Ontario. Further, we used the post-policy Ontario prices to estimate the potential reduction in other provinces.We estimate that total expenditure on generic drugs in Ontario during the second half of 2010 was between $181 and $194 million below what would be expected if prices had remained at pre-policy level. Over half of the reduction in spending was due to savings on just 10 generic ingredients. If other provinces had matched Ontario's prices, their expenditures over during the latter half of 2010 would have been $445 million lower.We found that if Ontario's pricing scheme were adopted nationally, overall spending on generic drugs in Canada would drop at least $1.28 billion annually--a 5% decrease in total prescription drug expenditure. Other provinces should seriously consider both changes to their generic drug prices and the use of more competitive bulk purchasing policies.

    The objective of this study was to compare treatment persistence and rates of seizure-related events in patients who initiate antiepileptic drug (AED) therapy with a generic versus a brand-name product. We used linked electronic medical and pharmacy claims data to identify Medicare beneficiaries who initiated one of five AEDs (clonazepam, gabapentin, oxcarbazepine, phenytoin, zonisamide). We matched initiators of generic versus brand-name versions of these drugs using a propensity score that accounted for demographic, clinical, and health service utilization variables. We used a Cox proportional hazards model to compare rates of seizure-related emergency room (ER) visit or hospitalization (primary outcome) and ER visit for bone fracture or head injury (secondary outcome) between the matched generic and brand-name initiators. We also compared treatment persistence, measured as time to first 14-day treatment gap, between generic and brand-name initiators. We identified 19,760 AED initiators who met study eligibility criteria; 18,306 (93%) initiated a generic AED. In the matched cohort, we observed 47 seizure-related hospitalizations and ER visits among brand-name initiators and 31 events among generic initiators, corresponding to a hazard ratio of 0.53 (95% confidence interval, 0.30 to 0.96). Similar results were observed for the secondary clinical endpoint and across sensitivity analyses. Mean time to first treatment gap was 124.2 days (standard deviation [sd], 125.8) for brand-name initiators and 137.9 (sd, 148.6) for generic initiators. Patients who initiated generic AEDs had fewer adverse seizure-related clinical outcomes and longer continuous treatment periods before experiencing a gap than those who initiated brand-name versions.

    To review the literature on consumers' knowledge, attitudes and opinions of the use of generic medicines. A narrative review of studies conducted from 1970 to 2008 on consumers perceptions and views towards generic medicines was performed. An extensive literature search was undertaken using indexing services available at the authors' institution library. The following keywords were used for the search: brand, generic, multisource, medications, medicines, drugs, pharmaceuticals and consumers, customers, and patients. Electronic databases searched were Medline, Inside Web, ISI Web of Knowledge, Science Direct, Springer Link, JSTOR, Proquest, Ebsco Host and Google Scholar. These electronic databases were searched for full text papers published in English from 1970 to October 2008. Twenty studies were identified. Eleven were from the USA, four were from Europe, two were from Canada and one each was from Australia, Brazil and Malaysia. In general, consumers showed mixed reactions towards the use of generic medicines. This was evident from the divergence of views observed by country development level, consumers' socioeconomic characteristics, drug product characteristics, pharmaceutical reimbursement system, policy environment, contact with health care professionals, past experience with medications, and knowledge of the seriousness of a medical condition. Patient confidence and knowledge pertaining to generic medicines use have increased over the past four decades, especially in developed countries. Mass educational efforts, financial incentives, and greater communication among patients and health care professionals were seen as major drivers to the uptake of generic medicines among consumers.

    The aim of this study was to fill the lack of knowledge regarding a more grounded exploration of the consumer's decision-making process in the context of generic drugs. In this perspective, a model, within the theoretical framework of the Theory of Planned Behaviour (TPB), for studying the consumers' purchase intention of generic drugs was developed. An online survey on 2,222 Italian people who bought drugs in the past was conducted. The proposed model was tested through structural equation modelling (SEM). Almost all the constructs considered in the model, except the perceived behavioural control, contribute to explain the consumer's purchase intention of generic drugs, after controlling for demographic variables (age, income, education). Specifically, attitude, subjective norm, past behaviour, self-identity and trust in the pharmacist have a positive influence on the intention to buy generic drugs. On the contrary, perceived risk towards products and brand sensitivity act negatively. The results of the present study could be useful to public policy makers in developing effective policies and educational campaigns aimed at promoting generic drugs. Specifically, marketing efforts should be directed to inform consumers about the generic drugs' characteristics to mitigate the perceived risk towards these products and to raise awareness during their decision-making process.

    Full Text Available The cost of pharmaceuticals, as a percentage of total healthcare spending, has been rising worldwide. This has resulted in strained national budgets and a high proportion of people without access to essential medications. Though India has become a global hub of generic drug manufacturing, the expected benefits of cheaper drugs are not translating into savings for ordinary people. This is in part due to the rise of branded generics, which are marketed at a price point close to the innovator brands. Unbranded generic medicines are not finding their way into prescriptions due to issues of confidence and perception, though they are proven to be much cheaper and comparable in efficacy to branded medicines. The drug inventory of unbranded generic manufacturers fares reasonably when reviewed using the World Health Organization-Health Action International (WHO-HAI tool for analysing drug availability. Also, unbranded generic medicines are much cheaper when compared to the most selling brands and they can bring down the treatment costs in primary care and family practice. We share our experience in running a community pharmacy for an urban health center in the Pathanamthitta district of Kerala State, which is run solely on generic medicines. The drug availability at the community pharmacy was 73.3% when analyzed using WHO-HAI tool and the savings for the final consumers were up to 93.1%, when compared with most-selling brand of the same formulation.

In 2010, generic of the calcium channel blockers (CCBs) represented 4.08 DDD/1 000 inhabitants/day (82.09%), followed by angiotensin converting enzyme inhibitors (ACEI) by 2.40 DDD/1 000 inhabitants/day (48.29%). The generics market of CCBs is the most dominant and represented in 2010, 79.21% in volume and 62.58% in value. In developing countries like Morocco, the generic drug is a key element for access to treatment especially for the poor population. © 2013 Société Française de Pharmacologie et de Thérapeutique.

  7. IAEA's experience in compiling a generic component reliability data base

    Reliability data are an essential part of probabilistic safety assessment. The quality of data can determine the quality of the study as a whole. It is obvious that component failure data originated from the plant being analyzed would be most appropriate. However, in few cases complete reliance on plant experience is possible, mainly because of the rather limited operating experience. Nuclear plants, although of different design, often use fairly similar components, so some of the experience could be combined and transferred from one plant to another. In addition information about component failures is available also from experts with knowledge on component design, manufacturing and operation. That bring us to the importance of assessing generic data. (Generic is meant to be everything that is not plant specific regarding the plant being analyzed). The generic data available in the open literature, can be divided in three broad categories. The first one includes data base used in previous analysis. These can be plant specific or updated from generic with plant specific information (latter case deserve special attention). The second one is based on compilation of plants' operating experience usually based on some kind of event reporting system. The third category includes data sources based on expert opinions (single or aggregate) or combination of expert opinions and other nuclear and non-nuclear experience. This paper reflects insights gained in compiling data from generic data sources and highlights advantages and pitfalls of using generic component reliability data in PSAs

    Authorized generics are identical in formulation to brand drugs, manufactured by the brand company but marketed as a generic. Generics, marketed by generic manufacturers, are required to demonstrate pharmaceutical and bioequivalence to the brand drug, but repetition of clinical trials is not required. This retrospective cohort study compared outcomes for generics and authorized generics, which serves as a generic vs. brand proxy that minimizes bias against generics. For the seven drugs studied between 1999 and 2014, 5,234 unique patients were on brand drugs prior to generic entry and 4,900 (93.6%) switched to a generic. During the 12 months following the brand-to-generic switch, patients using generics vs. authorized generics were similar in terms of outpatient visits, urgent care visits, hospitalizations, and medication discontinuation. The likelihood of emergency department (ED) visits was slightly higher for authorized generics compared with generics. These data suggest that generics were clinically no worse than their proxy brand comparators. © 2017 American Society for Clinical Pharmacology and Therapeutics.

  10. Generic Regional Development Strategies from Local Stakeholders' Scenarios - an Alpine Village Experience

    Full Text Available The article discusses the participatory elaboration of strategies for sustainable regional development in an Alpine tourist region in Austria to cope with global change effects evolving locally, considering climate change, economic change as well as (local societal change. Local stakeholders in an Alpine village in the Montafon region contributed in workshops to achieve the final results: participant teams conducted system analyses of the regional system to explore key elements of the region. Narrative scenarios described possible positive and negative development trends and indicated the critical issues controlling future development; 3D-images of landscape transition simulations show the consequences of certain development directions. Alternative development directions supported the local stakeholders to elaborate regional development strategies. In the end, the scientist team derived generic strategies for Alpine regions based on the locally developed strategy bundle. The article presents the intention, progress and outcome of the participatory approach and elaborates the potential to derive generic strategies from local ones and discusses the possibly occurring conflicts regarding cross-scale transfers of these local strategies. Overall, tourism was seen as a key element for future regional development, which can on the one hand derogate Alpine regions and is on the other hand threatened by climate change and diminution of landscape attractiveness. The suggested development strategies will help to cope with global change issues mitigating the negative consequences on the local society and environment.

  12. Why are dunkels sticky? Preschoolers infer functionality and intentional creation for artifact properties learned from generic language.

    Cimpian, Andrei; Cadena, Cristina

    2010-10-01

    Artifacts pose a potential learning problem for children because the mapping between their features and their functions is often not transparent. In solving this problem, children are likely to rely on a number of information sources (e.g., others' actions, affordances). We argue that children's sensitivity to nuances in the language used to describe artifacts is an important, but so far unacknowledged, piece of this puzzle. Specifically, we hypothesize that children are sensitive to whether an unfamiliar artifact's features are highlighted using generic (e.g., "Dunkels are sticky") or non-generic (e.g., "This dunkel is sticky") language. Across two studies, older-but not younger-preschoolers who heard such features introduced via generic statements inferred that they are a functional part of the artifact's design more often than children who heard the same features introduced via non-generic statements. The ability to pick up on this linguistic cue may expand considerably the amount of conceptual information about artifacts that children derive from conversations with adults.

    2015-01-01

    We show the effects of supersymmetric higher derivative terms on inflation models in supergravity. The results show that such terms generically modify the effective kinetic coefficient of the inflaton during inflation if the cut off scale of the higher derivative operators is sufficiently small. In such a case, the η-problem in supergravity does not occur, and we find that the effective potential of the inflaton generically becomes a power type potential with a power smaller than two

    Meal pattern analysis can be complex because of the large variability in meal consumption. The use of aggregated, generic meal data may address some of these issues. The objective was to develop a meal coding system and use it to explore meal patterns. Dietary data were used from the National Adult Nutrition Survey (2008-2010), which collected 4-d food diary information from 1500 healthy adults. Self-recorded meal types were listed for each food item. Common food group combinations were identified to generate a number of generic meals for each meal type: breakfast, light meals, main meals, snacks, and beverages. Mean nutritional compositions of the generic meals were determined and substituted into the data set to produce a generic meal data set. Statistical comparisons were performed against the original National Adult Nutrition Survey data. Principal component analysis was carried out by using these generic meals to identify meal patterns. A total of 21,948 individual meals were reduced to 63 generic meals. Good agreement was seen for nutritional comparisons (original compared with generic data sets mean ± SD), such as fat (75.7 ± 29.4 and 71.7 ± 12.9 g, respectively, P = 0.243) and protein (83.3 ± 26.9 and 80.1 ± 13.4 g, respectively, P = 0.525). Similarly, Bland-Altman plots demonstrated good agreement (<5% outside limits of agreement) for many nutrients, including protein, saturated fat, and polyunsaturated fat. Twelve meal types were identified from the principal component analysis ranging in meal-type inclusion/exclusion, varying in energy-dense meals, and differing in the constituents of the meals. A novel meal coding system was developed; dietary intake data were recoded by using generic meal consumption data. Analysis revealed that the generic meal coding system may be appropriate when examining nutrient intakes in the population. Furthermore, such a coding system was shown to be suitable for use in determining meal-based dietary patterns. © 2015

  15. How Abbott’s Fenofibrate Franchise Avoided Generic Competition

    2013-01-01

    The ongoing debate concerning the efficacy of fenofibrate has overshadowed an important aspect of the drug’s history: Abbott, the maker of branded fenofibrate, has produced several bioequivalent reformulations, which dominate the market even though generic fenofibrate has been available for almost a decade. This continued use of branded formulations, which cost twice as much as generic versions of fenofibrate, imposes an annual cost of approximately $700 million on our healthcare system. Abbott maintained its dominance of the fenofibrate market, in part, through a complex switching strategy involving the sequential launch of branded reformulations that had not been shown to be superior to the first generation product and patent litigation that delayed the approval of generic formulations. The small differences in dose of the newer branded formulations prevented substitution with generics of older generation products. As soon as direct generic competition seemed likely at the new dose level where substitution would be allowed, Abbott would launch another reformulation and the cycle would repeat. Our objective, using the fenofibrate example, is to describe how current policy can allow pharmaceutical companies to maintain market share using reformulations of branded medications without demonstrating the superiority of next generation products.

  17. Method for developing cost estimates for generic regulatory requirements

    International Nuclear Information System (INIS)

    1985-01-01

    The NRC has established a practice of performing regulatory analyses, reflecting costs as well as benefits, of proposed new or revised generic requirements. A method had been developed to assist the NRC in preparing the types of cost estimates required for this purpose and for assigning priorities in the resolution of generic safety issues. The cost of a generic requirement is defined as the net present value of total lifetime cost incurred by the public, industry, and government in implementing the requirement for all affected plants. The method described here is for commercial light-water-reactor power plants. Estimating the cost for a generic requirement involves several steps: (1) identifying the activities that must be carried out to fully implement the requirement, (2) defining the work packages associated with the major activities, (3) identifying the individual elements of cost for each work package, (4) estimating the magnitude of each cost element, (5) aggregating individual plant costs over the plant lifetime, and (6) aggregating all plant costs and generic costs to produce a total, national, present value of lifetime cost for the requirement. The method developed addresses all six steps. In this paper, we discuss on the first three

    Full Text Available The Caesalpinia group is a large pantropical clade of ca. 205 species in subfamily Caesalpinioideae (Leguminosae in which generic delimitation has been in a state of considerable flux. Here we present new phylogenetic analyses based on five plastid and one nuclear ribosomal marker, with dense taxon sampling including 172 (84% of the species and representatives of all previously described genera in the Caesalpinia group. These analyses show that the current classification of the Caesalpinia group into 21 genera needs to be revised. Several genera (Poincianella, Erythrostemon, Cenostigma and Caesalpinia sensu Lewis, 2005 are non-monophyletic and several previously unclassified Asian species segregate into clades that merit recognition at generic rank. In addition, the near-completeness of our taxon sampling identifies three species that do not belong in any of the main clades and these are recognised as new monospecific genera. A new generic classification of the Caesalpinia group is presented including a key for the identification of genera, full generic descriptions, illustrations (drawings and photo plates of all genera, and (for most genera the nomenclatural transfer of species to their correct genus. We recognise 26 genera, with reinstatement of two previously described genera (Biancaea Tod., Denisophytum R.

    This report consist in the development of a generic nuclear power plant component failure data bank. This data bank was implemented in a PC-XT microcomputer, IBM compatible, using the Open Access II program. Generic failure data tables for Westinghouse nuclear power plants and for general PWR power plants are presented. They are the final product of a research which included a preselection and a selection of data collected from the available sources in the library of CNEN (National Nuclear Energy Commission) and from the CIN/CNEN (Neclear Information Center). Futhermore, a proposal of evaluating models of average failure rates of pumps and valves are also presented. Through the electronic data bank one can easily have a generic view of failure rate ranges as well as failure models foe a certain component. It is very importante to develop procedures to collect and store generic failure data that can be quickly accessed, in order to update the Probabilistic Safety Study of Angra-1 and to used in studies which may have component failures of nuclear power plant safety systems. In the future, data specialization can be achieved by means of statistical calculations involving specific data collected from the operational experience of Angra-1 nuclear power plant and the generic data bank.

  20. The generic drug user fee amendments: an economic perspective

    Science.gov (United States)

    Berndt, Ernst R; Murphy, Stephen J

    2018-01-01

    Abstract Since the vast majority of prescription drugs consumed by Americans are off patent (‘generic’), their regulation and supply is of wide interest. We describe events leading up to the US Congress's 2012 passage of the Generic Drug User Fee Amendments (GDUFA I) as part of the Food and Drug Administration Safety and Innovation Act (FDASIA). Under GDUFA I, generic manufacturers agreed to pay approximately $300 million in fees each year of the five-year program. In exchange, the US Food and Drug Administration (FDA) committed to performance goals. We describe GDUFA I’s FDA commitments, provisions, goals, and annual fee structure and compare it to that entailed in the authorization and implementation of GDUFA II on October 1, 2017. We explain how user fees required under GDUFA I erected barriers to entry and created scale and scope economies for incumbent manufacturers. Congress changed user fees under GDUFA II in part to lessen these incentives. In order to initiate and sustain user fees under GDUFA legislation, FDA requires the submission of self-reported data on generic manufacturers including domestic and foreign facilities. These data are public and our examination of them provides an unprecedented window into the recent organization of generic drug manufacturers supplying the US market. Our results suggest that generic drug manufacturing is increasingly concentrated and foreign. We discuss the implications of this observed market structure for GDUFA II’s implementation among other outcomes. PMID:29707218

    1991-01-01

    Reliability data are essential in probabilistic safety assessment, with component reliability parameters being particularly important. Component failure data which is plant specific would be most appropriate but this is rather limited. However, similar components are used in different designs. Generic data, that is all data that is not plant specific to the plant being analyzed but which relates to components more generally, is important. The International Atomic Energy Agency has compiled the Generic Component Reliability Data Base from data available in the open literature. It is part of the IAEA computer code package for fault/event tree analysis. The Data Base contains 1010 different records including most of the components used in probabilistic safety analyses of nuclear power plants. The data base input was quality controlled and data sources noted. The data compilation procedure and problems associated with using generic data are explained. (UK)

    Full Text Available While there are several techniques for analyzing the impact of claims on time schedule and productivity,very few are considered adequate and comprehensive to consider risks and uncertainties.A generic approach for claims analysis using simulation is proposed. The formulation of the generic methodology presented in this paper depends on three simulation models;As-Planned Model (APM,As-Built Model (ABM, and What-Would-HaveBeenModel(WWHBM. The proposed generic methodology as presented in this paper provides a good basis as a more elaborate approach to better analyze claims and their impacts on project time and productivity utilizing discrete event simulation.The approach proposed allows for scenario analysis to account for the disputed events and workflow disruptions. The proposed models will assist claimants in presenting their cases effectively and professionally.

    Mosleh, A.; Apostolakis, G.

    1985-01-01

    The data analysis task in a probabilistic risk assessment (PRA) involves the assessment of data needs, the collection of information, and, finally, the analysis of the data to generate estimates for various parameters. This paper describes a framework for developing a data base for component failure rates and presents mathematical methods for the analysis of various types of information. The discussion is focused on the development of generic data bases used in PRAs. For plants without an operating history, the generic distributions are used directly to calculate component unavailability. In the case of plants that have operated for some time, the generic distributions can be used as priors in Bayesian analysis and, thus, specialized by plant-specific experience

  5. Promoting and regulating generic medicines: Brazil in comparative perspective

    2017-04-01

    Full Text Available ABSTRACT Promoting the use of generic drugs can constitute a core instrument for countries’ national pharmaceutical policies, one that reduces drug expenditure while expanding health care access. Despite the potential importance of such policy measures and the differences among national practices, scholars embarking on comparative analysis lack a roadmap for determining which dimensions of generic drug policy to assess and compare. This report fills that gap by considering national rules and regulations across four dimensions deemed crucial to any evaluation: demonstrated therapeutic equivalence; pharmaceutical packaging and labeling; drug prescription; and drug substitution. Furthermore, this report examines how the diverse interests of public and private sector stakeholders might shape generic drug policy and its implementation. To illustrate the challenges and conflicts behind policy development and implementation, this report focuses on the case of Brazil.

    2007-06-01

    Since the enactment of the 2002 legislative measures favoring the prescription of generic drugs, various quantitative studies have shown that approval by prescribers and users has risen in France. Nevertheless, scepticism remains as well as distrust towards these drugs focusing on their effectiveness compared with brand-name drugs, on potential dangers, and on the interruption they cause in prescription and consumption habits. Using a comprehensive approach, this article analyzes the social and cultural logic behind the negative image of generic drugs. The materials issued from an ethnographic study on the prescription of drugs for high blood pressure. Sixty-eight interviews were undertaken between April 2002 and October 2004 with people (39 women and 29 men, between the age of 40 and 95, 52 over the age of 60) treated for over a year for high blood pressure in rural areas in the Southeast of France. Thirteen people provided unsolicited opinions about generic drugs. Analysis of the information collected shows that users have various representations of generic drugs, including the idea of counterfeited and foreign drugs. These representations interfere with the adjustment process and the development of consumer loyalty. They are part of a set of social representations about drugs which form and express the user's reality. In these representations, the drug is an ambivalent object, carrier of both biological effectiveness and toxicity; it is also the metonymical extension of the prescriber, bestowing upon the prescription a symbolic value. By placing the generic drug in its network of symbolic and social meaning, this study highlights the coherence of the scepticism towards generic drugs by consumers (and prescribers) with a system of common opinion in which drugs are everyday things, personalized and compatible with users, symbolic exchange carriers in the physician-patient relationship, and in which confidence in the drug is also that given to the health care

    We experienced two cases of pulmonary aspergillosis, which deteriorated during treatment with generic itraconazole (ITCZ) because of low plasma concentration. One case was chronic pulmonary aspergillosis and the other was allergic bronchopulmonary aspergillosis (ABPA). Treatment of both cases was started with a brand-name-ITCZ, and changed to a generic ITCZ. Deterioration of pulmonary aspergillosis occurred after 8 months and 9 months from change to generic ITCZ respectively. In the first case, the ITCZ-plasma concentration was 46.9 ng/mL and of OH-ITCZ 96.5 ng/mL with generic ITCZ at the dose of 300 mg/day, but increased to 1,559.7 ng/mL and to 2,485.0 ng/mL with the brand-name-ITCZ 300 mg/day, respectively. In the second case, the ITCZ-plasma concentration was 27.2 ng/mL and of OH-ITCZ 20.1 ng/mL with 150 mg/day for generic ITCZ, but reached 857.3 ng/mL and to 1,144.2 ng/ml with the brand-name-ITCZ 300 mg/day, respectively. After treatment failure, the first case was changed to voriconazole, then brand-name-ITCZ 300 mg/day, and the second case to the brand-name-ITCZ 300 mg/day, with successful clinical course. Plasma concentrations of ITCZ can differ significantly depending on the patient or type of ITCZ. The ITCZ-plasma concentration should be controlled after changing from a brand-name-ITCZ to a generic ITCZ.

    2018-05-01

    Full Text Available Context: Malarial remains a leading course of death in developing countries. Current treatment protocol involves the use of artemisinin-based combination therapy. In endemic areas, cost of treatment is a concern hence generic prescription is on the high. It is therefore necessary to investigate how equivalent or otherwise the generics are to the innovator brand Coatem®. Aims: To compare the physicochemical properties and in vivo bioavailability of a locally manufactured generic artemether-lumefantrine tablet formulation and that of the innovator brand sold on the Kumasi market, Ghana. Methods: The most used locally manufactured generic and the innovator brands were sampled from retail pharmacies. The samples were confirmed by colorimetry. Pharmaceutical equivalence of the brands was determined using compendial tests. In vivo bioavailability study on the two brands was done using a two-period, single dose, cross-over design involving 20 healthy rabbits. Pharmacokinetic parameters (AUC0-72, AUC0-∞, and Cmax for both brands derived from the study were analysed statistically. Results: Both the generic and innovator brands passed the physicochemical tests. The artemether component of both brands complied with the pharmacopoeia specification for dissolution testing while the lumefantrine did not. Average bioequivalence was demonstrated per the FDA criterion with the geometric mean ratios and corresponding 90% confidence intervals falling within the acceptable limits of 0.80 – 1.25. Conclusions: Based on the similarity demonstrated between the two brands, evidence have been shown to support substitutability of the often-expensive innovator brand with the affordable locally produced brand.

    We study butterfly effect in D-dimensional gravitational theories containing terms quadratic in Ricci scalar and Ricci tensor. One observes that due to higher order derivatives in the corresponding equations of motion there are two butterfly velocities. The velocities are determined by the dimension of operators whose sources are provided by the metric. The three dimensional TMG model is also studied where we get two butterfly velocities at generic point of the moduli space of parameters. At critical point two velocities coincide.

    The US Food and Drug Administration Adverse Event Reporting System (FAERS), a post-marketing safety database, can be used to differentiate brand versus generic safety signals. To explore the methods for identifying and analyzing brand versus generic adverse event (AE) reports. Public release FAERS data from January 2004 to March 2015 were analyzed using alendronate and carbamazepine as examples. Reports were classified as brand, generic, and authorized generic (AG). Disproportionality analyses compared reporting odds ratios (RORs) of selected known labeled serious adverse events stratifying by brand, generic, and AG. The homogeneity of these RORs was compared using the Breslow-Day test. The AG versus generic was the primary focus since the AG is identical to brand but marketed as a generic, therefore minimizing generic perception bias. Sensitivity analyses explored how methodological approach influenced results. Based on 17,521 US event reports involving alendronate and 3733 US event reports involving carbamazepine (immediate and extended release), no consistently significant differences were observed across RORs for the AGs versus generics. Similar results were obtained when comparing reporting patterns over all time and just after generic entry. The most restrictive approach for classifying AE reports yielded smaller report counts but similar results. Differentiation of FAERS reports as brand versus generic requires careful attention to risk of product misclassification, but the relative stability of findings across varying assumptions supports the utility of these approaches for potential signal detection.

    This study aims to develop a typology of generic meeting places based on social contact and mixing of relevance for infectious disease transmission. Data were collected by means of a contact diary survey conducted on a representative sample of the Swedish population. The typology is derived from a cluster analysis accounting for four dimensions associated with transmission risk: visit propensity and its characteristics in terms of duration, number of other persons present and likelihood of physical contact. In the analysis, we also study demographic, socio-economic and geographical differences in the propensity of visiting meeting places. The typology identifies the family venue, the fixed activity site, the family vehicle, the trading plaza and the social network hub as generic meeting places. The meeting place typology represents a spatially explicit account of social contact and mixing relevant to infectious disease modelling, where the social context of the outbreak can be highlighted in light of the actual infectious disease.

  18. Endogenous versus exogenous generic reference pricing for pharmaceuticals.

    Antoñanzas, F; Juárez-Castelló, C A; Rodríguez-Ibeas, R

    2017-12-01

    In this paper we carry out a vertical differentiation duopoly model applied to pharmaceutical markets to analyze how endogenous and exogenous generic reference pricing influence competition between generic and branded drugs producers. Unlike the literature, we characterize for the exogenous case the equilibrium prices for all feasible relevant reference prices. Competition is enhanced after the introduction of a reference pricing system. We also compare both reference pricing systems on welfare grounds, assuming two different objective functions for health authorities: (i) standard social welfare and (ii) gross consumer surplus net of total pharmaceutical expenditures. We show that regardless of the objective function, health authorities will never choose endogenous reference pricing. When health authorities are paternalistic, the exogenous reference price that maximizes standard social welfare is such that the price of the generic drug is the reference price while the price of the branded drug is higher than the reference price. When health authorities are not paternalistic, the optimal exogenous reference price is such that the price of the branded drug is the reference price while the price of the generic drug is lower than the reference price.

  5. A proposal for generic competence assessment in a serious game

    María José Bezanilla

    2014-01-01

    Full Text Available This paper focuses on the design of a serious game for the teaching and assessment of generic competences, placing particular emphasis on the competences assessment aspect. Taking into account important aspects of competence assessment such as context, feedback and transparency, among other aspects, and using the University of Deusto's Generic Competences Assessment Model based on the defining of levels, indicators and descriptors as a reference point, a serious game has been designed for the development and evaluation of two Generic Competences: Problem Solving and Entrepreneurship, aimed at final-year undergraduate and first-year postgraduate students. The design process shows that having a Competence Assessment Model based on levels, indicators and descriptors is of great help in defining the game's scenarios and learning and assessment activities. Serious games can also be excellent resources to help in the development and assessment of generic competences, but not as a unique tool, since the concept of competence in itself is highly complex (integrating knowledge, skills, attitudes and values and some elements might require other methods and techniques for its development. It also reveals the difficulties of evaluating competences in general and through serious games in particular.

    Full Text Available During the past few years, organic light emitting diodes (OLEDs have been increasingly studied due to their emerging applicability. However, some of the properties of existing OLEDs could be improved, such as their overall efficiency and durability; these aspects have been addressed in the current study. A series of novel hole-transporting materials (HTMs 3a–c based on 4-(9H-carbazol-9-yltriphenylamine conjugated with different carbazole or triphenylamine derivatives have been readily synthesized by Suzuki coupling reactions.

  20. Generic Schemes for Single-Molecule Kinetics. 2: Information Content of the Poisson Indicator.

    Science.gov (United States)

    Avila, Thomas R; Piephoff, D Evan; Cao, Jianshu

    2017-08-24

    Recently, we described a pathway analysis technique (paper 1) for analyzing generic schemes for single-molecule kinetics based upon the first-passage time distribution. Here, we employ this method to derive expressions for the Poisson indicator, a normalized measure of stochastic variation (essentially equivalent to the Fano factor and Mandel's Q parameter), for various renewal (i.e., memoryless) enzymatic reactions. We examine its dependence on substrate concentration, without assuming all steps follow Poissonian kinetics. Based upon fitting to the functional forms of the first two waiting time moments, we show that, to second order, the non-Poissonian kinetics are generally underdetermined but can be specified in certain scenarios. For an enzymatic reaction with an arbitrary intermediate topology, we identify a generic minimum of the Poisson indicator as a function of substrate concentration, which can be used to tune substrate concentration to the stochastic fluctuations and to estimate the largest number of underlying consecutive links in a turnover cycle. We identify a local maximum of the Poisson indicator (with respect to substrate concentration) for a renewal process as a signature of competitive binding, either between a substrate and an inhibitor or between multiple substrates. Our analysis explores the rich connections between Poisson indicator measurements and microscopic kinetic mechanisms.

The philosophy behind cloud computing shares its view with green computing where computing environments and resources are not as subjects to own but as subjects of sustained use. However, converting currently used IT services to Software as a Service (SaaS cloud computing environments introduces several new risks. To mitigate such risks, existing software development processes must undergo significant remodeling. This study analyzes actual cases of SaaS cloud computing environment adoption as a way to derive four new best practices for software development and incorporates the identified best practices for currently-in-use processes. Furthermore, this study presents a design for generic software development processes that implement the proposed best practices. The design for the generic process has been applied to reinforce the weak points found in SaaS cloud service development practices used by eight enterprises currently developing or operating actual SaaS cloud computing services. Lastly, this study evaluates the applicability of the proposed SaaS cloud oriented development process through analyzing the feedback data collected from actual application to the development of a SaaS cloud service Astation.

    The structured expert elicitation process proposed by Cooke (1991), hereafter referred to as Cooke’s approach, is applied for the first time in the realm of structural collapse-fragility assessment for selected generic construction types. Cooke’s approach works on the principle of objective calibration scoring of judgments coupled with hypothesis testing used in classical statistics. The performance-based scoring system reflects the combined measure of an expert’s informativeness about variables in the problem area under consideration, and their ability to enumerate, in a statistically accurate way through expressing their true beliefs, the quantitative uncertainties associated with their assessments. We summarize the findings of an expert elicitation workshop in which a dozen earthquake-engineering professionals from around the world were engaged to estimate seismic collapse fragility for generic construction types. Development of seismic collapse fragility functions was accomplished by combining their judgments using weights derived from Cooke’s method. Although substantial effort was needed to elicit the inputs of these experts successfully, we anticipate that the elicitation strategy described here will gain momentum in a wide variety of earthquake seismology and engineering hazard and risk analyses where physical model and data limitations are inherent and objective professional judgment can fill gaps.

    Highlights: • Consequent implementation of the recommendations derived from the OECD/NEA ISP-47. • Phenomenological code-to-code comparison performed on plant scale. • Systematic identification and elimination of the user effect. • Identification of fundamental differences in the model basis. • Application to PAR system analysis. - Abstract: One outcome of the OECD/NEA ISP-47 activity was the recommendation to elaborate a ‘Generic Containment’ in order to allow comparing and rating the results obtained by different lumped-parameter models on plant scale. Within the European SARNET2 project ( (http://www.sar-net.eu)), such a Generic Containment nodalisation, based on a German PWR (1300 MW el ), was defined. This agreement on the nodalisation allows investigating the remaining differences among the results, especially the ‘user-effect’, related to the modelling choices, as well as fundamental differences in the underlying model basis in detail. The methodology applied in order to compare the different code predictions consisted of a series of three benchmark steps with increasing complexity as well as a systematic comparison of characteristic variables and observations. This paper summarises the benchmark series, the lessons learned during specifying the steps, comparing and discussing the results and finally gives an outlook on future steps

    The therapeutic equivalence of generic and brand name antiepileptic drugs has been questioned by neurologists and the epilepsy community. A potential contributor to such concerns is pharmaceutical quality. The objective was to assess the biopharmaceutic risk of brand name Lamictal 100 mg tablets and generic lamotrigine 100 mg tablets from several manufacturers. Lamotrigine was characterized in terms of the Biopharmaceutics Classification System (BCS), including aqueous solubility and Caco-2 permeability. A panel of pharmaceutical quality tests was also performed on three batches of Lamictal, three batches of Teva generic, and one batch of each of four other generics: appearance, identity, assay, impurity, uniformity of dosage units, disintegration, dissolution, friability, and loss on drying. These market surveillance results indicate that all brand name and generic lamotrigine 100 mg tablets passed all tests and showed acceptable pharmaceutical quality and low biopharmaceutic risk. Lamotrigine was classified as a BCS class IIb drug, exhibiting pH-dependent aqueous solubility and dissolution. At pH 1.2 and 4.5, lamotrigine exhibited high solubility, whereas lamotrigine exhibited low solubility at pH 6.8, including non-sink dissolution. Lamotrigine showed high Caco-2 permeability. The apparent permeability (Papp) of lamotrigine was (73.7 ± 8.7) × 10(-6) cm/s in the apical-to-basolateral (AP-BL) direction and (41.4 ± 1.6) × 10(-6) cm/s in the BL-AP direction, which were higher than metoprolol's AP-BL Papp of (21.2 ± 0.9) × 10(-6) cm/s and BL-AP Papp of (34.6 ± 4.6) × 10(-6) cm/s. Overall, lamotrigine's favorable biopharmaceutics from a drug substance perspective and favorable quality characteristics from a tablet formulation perspective suggest that multisource lamotrigine tablets exhibit a low biopharmaceutic risk.

  5. Analysis of the Italian generic medicines retail market: recommendations to enhance long-term sustainability.

    Italy is among the European countries with the lowest uptake of generic medicines. This paper provides a perspective on the Italian generic medicines retail market. Fast market entrance of generic medicines in Italy is hindered by several factors: the existence of Complementary Protection Certificates in the past, the large market for copies and multiple cases of patent linkage. Prices of generic medicines in Italy are low compared to other European countries. To contain pharmaceutical expenditure, pharmaceutical companies are currently forced to pay back in case of overspending, which disproportionally penalizes small and fast growing companies, to which most generic companies belong to. Current demand-side policies do not successfully stimulate the use of generic medicines. The current market environment surrounding the Italian generic medicines retail market (i.e., low prices, low volumes) threatens its long-term sustainability. Recommendations to enhance the long-term sustainability of the Italian generic medicines retail market round off this perspective paper.

  6. A generic library for large scale solution of PDEs on modern heterogeneous architectures

    Glimberg, Stefan Lemvig; Engsig-Karup, Allan Peter

    2012-01-01

    Adapting to new programming models for modern multi- and many-core architectures requires code-rewriting and changing algorithms and data structures, in order to achieve good efficiency and scalability. We present a generic library for solving large scale partial differential equations (PDEs......), capable of utilizing heterogeneous CPU/GPU environments. The library can be used for fast proto-typing of PDE solvers, based on finite difference approximations of spatial derivatives in one, two, or three dimensions. In order to efficiently solve large scale problems, we keep memory consumption...... and memory access low, using a low-storage implementation of flexible-order finite difference operators. We will illustrate the use of library components by assembling such matrix-free operators to be used with one of the supported iterative solvers, such as GMRES, CG, Multigrid or Defect Correction...

  7. A generic biokinetic model for predicting the behaviour of the lanthanide elements in the human body

    International Nuclear Information System (INIS)

    Taylor, D.M.; Leggett, R.W.

    2003-01-01

    Information on the biokinetics of the 15 elements of the lanthanide series, 57 La to 71 Lu, is too sparse to permit individual development of meaningful biokinetic models to describe the behaviour of each of the elements in humans. The lanthanides show a regular gradation in chemical properties across the series, and animal studies indicate that this is reflected in regular differences in their deposition in tissues such as the liver and skeleton. These regular differences in chemical and biological behaviour have been utilised to construct a generic lanthanide biokinetic model and to define element-specific parameters for each element in the series. This report describes the use of the available biokinetic data for humans and animals to derive the parameters for each of the elements. (author)

  8. Development of generic key performance indicators for PMBOK® using a 3D project integration model

    Directory of Open Access Journals (Sweden)

    2013-12-01

    Full Text Available Since Martin Barnes’ so-called ‘iron triangle’ circa 1969, much debate has occurred over how best to describe the fundamental constraints that underpin project success. This paper develops a 3D project integration model for PMBOK® comprising core constraints of scope, cost, time and risk as a basis to propose six generic key performance indicators (KPIs that articulate successful project delivery. These KPIs are defined as value, efficiency, speed, innovation, complexity and impact and can each be measured objectively as ratios of the core constraints. An overall KPI (denoted as s3/ctr is also derived. The aim in this paper is to set out the case for such a model and to demonstrate how it can be employed to assess the performance of project teams in delivering successful outcomes at various stages in the project life cycle. As part of the model’s development, a new PMBOK® knowledge area concerning environmental management is advanced.

  4. Generic strategies: an evolutionary and comparative study of three views

    Directory of Open Access Journals (Sweden)

    Sidney Chaves

    2010-04-01

    Full Text Available This study analyses visions of three of the most renowned authors regarding generic strategies, making a comparison among those visions along the time. To perform such comparison, two distinct works of each author were selected and then it is pointed out how changes showed up from one moment to another. The selected authors are Ansoff, Miles et al. and Porter, all responsible for three of the most spread typologies for generic strategies. From a chronological point of view, these typologies have been originally proposed between 1965 and 1980 and revisited between 1985 and 1988. Despite time passed from then until today, these typologies are still fully adequate and completely applicable to organizations' present reality. Contributions of this study reside on detailed presentation of each typology's major characteristics, due to detailed and judicious bibliography revision.

    1987-01-01

    As the number of operating nuclear power plants (NPP) increases, safety inspection has increased in importance. However, precisely what is important, and what is not important? What should one focus inspection efforts on. Over the last two years Probabilistic Risk Assessment (PR) techniques have been developed to aid in the inspection process. Broad interest in generic PRA-based methods has arisen in the past year, since only about 25% of the US nuclear power plants have completed PRAs, and also, inspectors want PRA-based tools for these plants. This paper describes the BNL program to develop generic BWR PRA-based inspection insights or inspection guidance designed to be applied to plants without PRAs

    A generic process has been developed to grow nearly defect-free arrays of (heterostructured) InP and GaP nanowires. Soft nano-imprint lithography has been used to pattern gold particle arrays on full 2 inch substrates. After lift-off organic residues remain on the surface, which induce the growth of additional undesired nanowires. We show that cleaning of the samples before growth with piranha solution in combination with a thermal anneal at 550 deg. C for InP and 700 deg. C for GaP results in uniform nanowire arrays with 1% variation in nanowire length, and without undesired extra nanowires. Our chemical cleaning procedure is applicable to other lithographic techniques such as e-beam lithography, and therefore represents a generic process.

  8. Generic procedures for assessment and response during a radiological emergency

    International Nuclear Information System (INIS)

    2000-08-01

    One of the most important aspects of managing a radiological emergency is the ability to promptly and adequately determine and take actions to protect members of the public and emergency workers. Radiological accident assessment must take account of all critical information available at any time and must be an iterative and dynamic process aimed at reviewing the response as more detailed and complete information becomes available. This manual provides the tools, generic procedures and data needed for an initial response to a non-reactor radiological accident. This manual is one out of a set of IAEA publications on emergency preparedness and response, including Method for the Development of Emergency Response Preparedness for Nuclear or Radiological Accidents (IAEA-TECDOC-953), Generic Assessment Procedures for Determining Protective Actions During a Reactor Accident (IAEA-TECDOC-955) and Intervention Criteria in a Nuclear or Radiation Emergency (Safety Series No. 109)

    Pacific Northwest Laboratory developed a method for forecasting potential locations and startup sequences of nuclear power plants that will be required in the future but have not yet been specifically identified by electric utilities. Use of the method results in numerical ratings for potential nuclear power plant sites located in each of the 10 federal energy regions. The rating for each potential site is obtained from numerical factors assigned to each of 5 primary siting characteristics: (1) cooling water availability, (2) site land area, (3) power transmission land area, (4) proximity to metropolitan areas, and (5) utility plans for the site. The sequence of plant startups in each federal energy region is obtained by use of the numerical ratings and the forecasts of generic nuclear power plant startups obtained from the EIA Middle Case electricity forecast. Sites are assigned to generic plants in chronological order according to startup date.

    This document is one of three. It describes various security mechanisms and a security policy profile for a generic space-based communication architecture. Two other documents accompany this document- an Operations Concept (OpsCon) and a communication architecture document. The OpsCon should be read first followed by the security policy profile described by this document and then the architecture document. The overall goal is to design a generic space exploration communication network architecture that is affordable, deployable, maintainable, securable, evolvable, reliable, and adaptable. The architecture should also require limited reconfiguration throughout system development and deployment. System deployment includes subsystem development in a factory setting, system integration in a laboratory setting, launch preparation, launch, and deployment and operation in space.

    Switching brand name medications to generics is recommended in France in the interest of cost effectiveness but patients and physicians are sometimes not convinced that switching is appropriate. Some antiretroviral (ARV) generics (ZDV, 3TC, NVP) have been marketed in France since 2013. A multicentric cross-sectional survey was performed in September 2013 to evaluate the perception of generics overall and ARV generics in physicians and HIV-infected patients and factors associated to their acceptability. Adult HIV outpatients were asked to complete a self-questionnaire on their perception of generics. Physicians completed a questionnaire on the acceptability of generics and ARV generics. Socio-demographic data, medical history and HIV history were collected. 116 physicians in 33 clinics (68% in University Hospital) included 556 patients (France-native 77%, active employment 59%, covered by social Insurance 100%, homosexual/bisexual contamination 47%, median HIV duration 13 years, hepatitis coinfection 16%, on ARV therapy 95%). Overall, patients accepted and had confidence in generics in 76% and 55% of the cases, respectively. Switching ARVs for generics was accepted by 44% of the patients but only by 17% if the pill burden was going to increase. 75% of the physicians would prescribe generics, but this decreased to only 26% if the combo had to be broken. The main reasons for non-prescription of generics were previous brand name ARV-induced side effects (35%), refusal of generics overall (37%), lack of understanding of generics (26%), risk of non-observance of treatment (44%), anxiety (47%) and depressive symptoms (25%). In multivariate analysis, factors associated with the acceptability of ARV generics in patients were the use of generics overall (p<0.001) and in physicians, the absence of concern regarding the drug efficacy (p<0.001) and being aware that the patient would accept generics overall (p=0.03) and ARV generics (p=0.04).

    We study quantum stability bound on the mass of scalaron in generic theories of f(R) gravity. We show that in these scenarios, the scalaron mass increases faster with local density of the environment than one-loop quantum correction to it thereby leading to violation of quantum bound on the chameleon mass. The introduction of quadratic curvature corrections in the action are shown to stabilize the model.

    1976-01-01

    ERDA is preparing a generic environmental impact statement on the treatment and disposal of waste resulting from commercial reactors and post fission operations in the light water reactor (LWR) fuel cycle. Expert contributions will be provided by many of the ERDA national laboratories and contractors. The waste management aspects of the statement will be based on available technology as presented in the recently issued ''Alternatives for Managing Waste from Reactors and Post Fission Operations in the LWR Fuel Cycle,'' ERDA-76-43 Document. This 1500 page, five volume Technical Alternative Document (TAD) describes the status of technology (to September, 1975) for handling post fission radioactive waste generated by the production of electricity by nuclear power light water reactor-generator systems. The statement will be generic in nature discussing typical or hypothetical facilities in typical or hypothetical environments. It is not intended to replace environmental statements required in support of specific projects nor for Nuclear Regulatory Commission licensing procedures. A major purpose of the generic statement is to inform the public and to solicit comments on the ERDA program for: (1) the final disposition of commercial radioactive waste, (2) waste treatment, (3) waste interim storage, and (4) transportation of waste. The statement will discuss the ERDA contingency program to provide retrievable storage of such waste if they should be transferred to Federal custody prior to the availability of the geologic isolation facilities for terminal disposal. The generic statement will not address radioactive waste resulting from U.S. Defense Programs, the mining or milling of uranium, the management of waste from the breeder reactor program, waste from other nations, nor will it include an evaluation of the impact of waste resulting from power sources other than light water reactors

    2018-04-01

    Thermodynamically admissible evolution equations for non-equilibrium systems are known to possess a distinct mathematical structure. Within the GENERIC (general equation for the non-equilibrium reversible-irreversible coupling) framework of non-equilibrium thermodynamics, which is based on continuous time evolution, we investigate the possibility of preserving all the structural elements in time-discretized equations. Our approach, which follows Moser's [1] construction of symplectic integrators for Hamiltonian systems, is illustrated for the damped harmonic oscillator. Alternative approaches are sketched.

    This article identifies the strategic types in the hospital industry based on the hospital's use of Porter's generic strategies in their pure and hybrid forms. The article also examines differences in performance of hospitals across strategic types. Results indicate that hospitals that follow a focussed cost leadership strategy, in general, have superior performance on a variety of performance measures, while hospitals that use a combination of cost leadership and differentiation perform the poorest. Implications of findings for hospital administrators are also discussed.

    The open critical XXZ spin chain with a general right boundary and a trivial diagonal left boundary is considered. Within this framework we propose a simple computation of the exact generic boundary S-matrix (with diagonal and non-diagonal entries), starting from the 'bare' Bethe ansatz equations. Our results as anticipated coincide with the ones obtained by Ghoshal and Zamolodchikov, after assuming suitable identifications of the bulk and boundary parameters

    A generic procedure for Bidirectional Reflectance Distribution Function (BRDF) normalization for airborne multispectral images has been developed and implemented as an add-on module of ENVI at the U.S. Department of Energy's Remote Sensing Laboratory. The main advantage of this procedure is that it does not require multiple image acquisitions over the same area for establishing empirical BRDF functions.

    2011-01-01

    Background The authors previously introduced a highly abstract generic insulin infusion pump (GIIP) model that identified common features and hazards shared by most insulin pumps on the market. The aim of this article is to extend our previous work on the GIIP model by articulating safety requirements that address the identified GIIP hazards. These safety requirements can be validated by manufacturers, and may ultimately serve as a safety reference for insulin pump software. Together, these two publications can serve as a basis for discussing insulin pump safety in the diabetes community. Methods In our previous work, we established a generic insulin pump architecture that abstracts functions common to many insulin pumps currently on the market and near-future pump designs. We then carried out a preliminary hazard analysis based on this architecture that included consultations with many domain experts. Further consultation with domain experts resulted in the safety requirements used in the modeling work presented in this article. Results Generic safety requirements for the GIIP model are presented, as appropriate, in parameterized format to accommodate clinical practices or specific insulin pump criteria important to safe device performance. Conclusions We believe that there is considerable value in having the diabetes, academic, and manufacturing communities consider and discuss these generic safety requirements. We hope that the communities will extend and revise them, make them more representative and comprehensive, experiment with them, and use them as a means for assessing the safety of insulin pump software designs. One potential use of these requirements is to integrate them into model-based engineering (MBE) software development methods. We believe, based on our experiences, that implementing safety requirements using MBE methods holds promise in reducing design/implementation flaws in insulin pump development and evolutionary processes, therefore improving

    Full Text Available BACKGROUND: The transition of the generic/biotechnology industry to innovation by investing in innovative R&D will enhance business expertise in biopharmaceutical development and manufacturing. The major impact of this evolution is on patient access to treatment and savings for the health care systems. OBJECTIVES: The aim of this paper is to investigate the innovative aspect of biosimilar and biobetter products, manufactured by some big generic companies. We will also try to explore the innovative business strategy, implementing this high risk product differentiation policy. METHODS: This qualitative research is conducted by a series of interviews with CEOs, physicians, and academics in different countries. The qualitative data obtained were analyzed by Nvivo9.2 software. A literature review has also contributed to our key findings. RESULTS: The results show that switching into biosimilars/biobetters is an innovative strategic choice, approved by some big generic pharmaceutical companies. The biosimilar/biobetter products can be considered innovative because of their value added quality. CONCLUSION: Expanding the product portfolio to biosimilars/biobetter can be considered as a long run strategy in the innovative business plans aiming to ensure the market access. Patients and their access to better treatments are major components of these innovative business models.

  9. A Generic Modeling Process to Support Functional Fault Model Development

    Maul, William A.; Hemminger, Joseph A.; Oostdyk, Rebecca; Bis, Rachael A.

    2016-01-01

    Functional fault models (FFMs) are qualitative representations of a system's failure space that are used to provide a diagnostic of the modeled system. An FFM simulates the failure effect propagation paths within a system between failure modes and observation points. These models contain a significant amount of information about the system including the design, operation and off nominal behavior. The development and verification of the models can be costly in both time and resources. In addition, models depicting similar components can be distinct, both in appearance and function, when created individually, because there are numerous ways of representing the failure space within each component. Generic application of FFMs has the advantages of software code reuse: reduction of time and resources in both development and verification, and a standard set of component models from which future system models can be generated with common appearance and diagnostic performance. This paper outlines the motivation to develop a generic modeling process for FFMs at the component level and the effort to implement that process through modeling conventions and a software tool. The implementation of this generic modeling process within a fault isolation demonstration for NASA's Advanced Ground System Maintenance (AGSM) Integrated Health Management (IHM) project is presented and the impact discussed.

  10. Origami building blocks: Generic and special four-vertices

    2016-02-01

    Four rigid panels connected by hinges that meet at a point form a four-vertex, the fundamental building block of origami metamaterials. Most materials designed so far are based on the same four-vertex geometry, and little is known regarding how different geometries affect folding behavior. Here we systematically categorize and analyze the geometries and resulting folding motions of Euclidean four-vertices. Comparing the relative sizes of sector angles, we identify three types of generic vertices and two accompanying subtypes. We determine which folds can fully close and the possible mountain-valley assignments. Next, we consider what occurs when sector angles or sums thereof are set equal, which results in 16 special vertex types. One of these, flat-foldable vertices, has been studied extensively, but we show that a wide variety of qualitatively different folding motions exist for the other 15 special and 3 generic types. Our work establishes a straightforward set of rules for understanding the folding motion of both generic and special four-vertices and serves as a roadmap for designing origami metamaterials.

    The purpose of this generic aging lessons learned (GALL) review is to provide a systematic review of plant aging information in order to assess materials and component aging issues related to continued operation and license renewal of operating reactors. Literature on mechanical, structural, and thermal-hydraulic components and systems reviewed consisted of 97 Nuclear Plant Aging Research (NPAR) reports, 23 NRC Generic Letters, 154 Information Notices, 29 Licensee Event Reports (LERs), 4 Bulletins, and 9 Nuclear Management and Resources Council Industry Reports (NUMARC IRs) and literature on electrical components and systems reviewed consisted of 66 NPAR reports, 8 NRC Generic Letters, 111 Information Notices, 53 LERs, 1 Bulletin, and 1 NUMARC IR. More than 550 documents were reviewed. The results of these reviews were systematized using a standardized GALL tabular format and standardized definitions of aging-related degradation mechanisms and effects. The tables are included in volumes 1 and 2 of this report. A computerized data base has also been developed for all review tables and can be used to expedite the search for desired information on structures, components, and relevant aging effects. A survey of the GALL tables reveals that all ongoing significant component aging issues are currently being addressed by the regulatory process. However, the aging of what are termed passive components has been highlighted for continued scrutiny. This report consists of Volume 2, which consists of the GALL literature review tables for the NUMARC Industry Reports reviewed for the report

    To determine whether brand-name glaucoma drops differ from generic equivalents in bottle design, viscosity, surface tension, and volume in North America. Experimental study. We studied 5 bottles each of 11 kinds of glaucoma drops. Density-based calculations of drop volume were assessed using 0.1 mg analytic balance. Viscosity was measured using rotational rheometery. Bottle tip diameter was measured using 0.05 mm Vernier calipers. Surface tension was measured using a Fisher Scientific (Ottawa, ON) tensiometer. For the American brand-name Timoptic XE, the average drop volume was 38 ± 3.1 μL versus 24 ± 1.5 μL of Timolol GFS (p brand-name Timoptic XE, the average drop volume was 42 ± 4.0 μL versus 25 ± 2 μL of timolol maleate EX (p brand-name Timoptic drop volume was 28 ± 1.4 μL versus 35 ± 1.9 μL Apo-Timop (p brand-name Timoptic delivered significantly smaller drop volumes than generic Apo-Timop. Careful consideration should be given to drop viscosity and bottle design when generic ophthalmic products are evaluated for interchangeability and market entry.

    2010-01-01

    To describe the history of generic prescription pricing programs at major pharmacy chains and their potential implications on prescribing, quality of care, and patient safety. Publicly available generic prescription discount program drug lists as of May 1, 2009. Fierce competition among major pharmacy chains such as Walgreens, CVS, and Walmart has led to a generic prescription pricing war with unclear public health implications. Introduced in 2006, currently 7 of the 10 largest pharmacy chains advertise a version of a deeply discounted medication (DDM) program, accounting for more than 25,000 locations nationally. By early 2008, almost 70 million Americans had used these programs. Although DDM programs lower drug costs for many patients, DDM formularies include potentially ineffective or harmful medications, have the potential to influence physician prescribing behavior, and may impair pharmacists' ability to review complete drug-dispensing records. DDMs are widespread but have the potential for unintended consequences on patients, providers, and the health care system. A systematic review of DDMs needs to evaluate the clinical, economic, and system-level implications of such programs.

    2014-03-01

    Fractional frequency reuse (FFR) has emerged as a viable solution to coordinate and mitigate cochannel interference (CCI) in orthogonal frequency-division multiple-access (OFDMA)-based wireless cellular networks. The incurred CCI in cellular networks with FFR is highly uncertain and varies as a function of various design parameters that include the user scheduling schemes, the transmit power distribution among multiple allocated subcarriers, the partitioning of the cellular region into cell-edge and cell-center zones, the allocation of spectrum within each zone, and the channel reuse factors. To this end, this paper derives a generic analytical model for uplink CCI in multicarrier OFDMA networks with FFR. The derived expressions capture several network design parameters and are applicable to any composite fading-channel models. The accuracy of the derivations is verified via Monte Carlo simulations. Moreover, their usefulness is demonstrated by obtaining closed-form expressions for the Rayleigh fading-channel model and by evaluating important network performance metrics such as ergodic capacity. Numerical results provide useful system design guidelines and highlight the trade-offs associated with the deployment of FFR schemes in OFDMA-based networks. © 2013 IEEE.

  16. Do higher-priced generic medicines enjoy a competitive advantage under reference pricing?

    Science.gov (United States)

    Puig-Junoy, Jaume

    2012-11-01

    In many countries with generic reference pricing, generic producers and distributors compete by means of undisclosed discounts offered to pharmacies in order to reduce acquisition costs and to induce them to dispense their generic to patients in preference over others. The objective of this article is to test the hypothesis that under prevailing reference pricing systems for generic medicines, those medicines sold at a higher consumer price may enjoy a competitive advantage. Real transaction prices for 179 generic medicines acquired by pharmacies in Spain have been used to calculate the discount rate on acquisition versus reimbursed costs to pharmacies. Two empirical hypotheses are tested: the discount rate at which pharmacies acquire generic medicines is higher for those pharmaceutical presentations for which there are more generic competitors; and, the discount rate at which pharmacies acquire generic medicines is higher for those pharmaceutical forms for which the consumer price has declined less in relation to the consumer price of the brand drug before generic entry (higher-priced generic medicines). An average discount rate of 39.3% on acquisition versus reimbursed costs to pharmacies has been observed. The magnitude of the discount positively depends on the number of competitors in the market. The higher the ratio of the consumer price of the generic to that of the brand drug prior to generic entry (i.e. the smaller the price reduction of the generic in relation to the brand drug), the larger the discount rate. Under reference pricing there is intense price competition among generic firms in the form of unusually high discounts to pharmacies on official ex-factory prices reimbursed to pharmacies. However, this effect is highly distorting because it favours those medicines with a higher relative price in relation to the brand price before generic entry.

    Generic bifurcation theory was classically well developed for smooth differential systems, establishing results for k-parameter families of planar vector fields. In the present study we focus on a qualitative analysis of 2-parameter families, , of planar Filippov systems assuming that Z 0,0 presents a codimension-two minimal set. Such object, named elementary simple two-fold cycle, is characterized by a regular trajectory connecting a visible two-fold singularity to itself, for which the second derivative of the first return map is nonvanishing. We analyzed the codimension-two scenario through the exhibition of its bifurcation diagram.

  19. Comparing Generic Drug Markets in Europe and the United States: Prices, Volumes, and Spending.

    Science.gov (United States)

    Wouters, Olivier J; Kanavos, Panos G; McKEE, Martin

    2017-09-01

    Policy Points: Our study indicates that there are opportunities for cost savings in generic drug markets in Europe and the United States. Regulators should make it easier for generic drugs to reach the market. Regulators and payers should apply measures to stimulate price competition among generic drugmakers and to increase generic drug use. To meaningfully evaluate policy options, it is important to analyze historical context and understand why similar initiatives failed previously. Rising drug prices are putting pressure on health care budgets. Policymakers are assessing how they can save money through generic drugs. We compared generic drug prices and market shares in 13 European countries, using data from 2013, to assess the amount of variation that exists between countries. To place these results in context, we reviewed evidence from recent studies on the prices and use of generics in Europe and the United States. We also surveyed peer-reviewed studies, gray literature, and books published since 2000 to (1) outline existing generic drug policies in European countries and the United States; (2) identify ways to increase generic drug use and to promote price competition among generic drug companies; and (3) explore barriers to implementing reform of generic drug policies, using a historical example from the United States as a case study. The prices and market shares of generics vary widely across Europe. For example, prices charged by manufacturers in Switzerland are, on average, more than 2.5 times those in Germany and more than 6 times those in the United Kingdom, based on the results of a commonly used price index. The proportion of prescriptions filled with generics ranges from 17% in Switzerland to 83% in the United Kingdom. By comparison, the United States has historically had low generic drug prices and high rates of generic drug use (84% in 2013), but has in recent years experienced sharp price increases for some off-patent products. There are policy

    2016-04-01

    This meta-analysis aimed to compare the efficacy and adverse events, either serious or mild/moderate, of all generic versus brand-name cardiovascular medicines. We searched randomized trials in MEDLINE, Scopus, EMBASE, Cochrane Controlled Clinical Trial Register, and ClinicalTrials.gov (last update December 1, 2014). Attempts were made to contact the investigators of all potentially eligible trials. Two investigators independently extracted and analyzed soft (including systolic blood pressure, LDL cholesterol, and others) and hard efficacy outcomes (including major cardiovascular adverse events and death), minor/moderate and serious adverse events. We included 74 randomized trials; 53 reported ≥1 efficacy outcome (overall sample 3051), 32 measured mild/moderate adverse events (n = 2407), and 51 evaluated serious adverse events (n = 2892). We included trials assessing ACE inhibitors (n = 12), anticoagulants (n = 5), antiplatelet agents (n = 17), beta-blockers (n = 11), calcium channel blockers (n = 7); diuretics (n = 13); statins (n = 6); and others (n = 3). For both soft and hard efficacy outcomes, 100 % of the trials showed non-significant differences between generic and brand-name drugs. The aggregate effect size was 0.01 (95 % CI -0.05; 0.08) for soft outcomes; -0.06 (-0.71; 0.59) for hard outcomes. All but two trials showed non-significant differences in mild/moderate adverse events, and aggregate effect size was 0.07 (-0.06; 0.20). Comparable results were observed for each drug class and in each stratified meta-analysis. Overall, 8 serious possibly drug-related adverse events were reported: 5/2074 subjects on generics; 3/2076 subjects on brand-name drugs (OR 1.69; 95 % CI 0.40-7.20). This meta-analysis strengthens the evidence for clinical equivalence between brand-name and generic cardiovascular drugs. Physicians could be reassured about prescribing generic cardiovascular drugs, and health care organization about endorsing their wider

    Full Text Available Introduction One of the main targets of planners, decision makers and governments is increasing society health with promotion and production of suitable and healthy food. One of the basic commodities that have important role in satisfaction of required human food is milk. So, some part of government and producer healthy budget allocate to milk consumption promotion by using generic advertising. If effectiveness of advertising budget on profitability is more, producer will have more willing to spend for advertising. Determination of optimal generic advertising budget is one of important problem in managerial decision making in producing firm as well as increase in consumption and profit and decrease in wasting and non-optimality of budget. Materials and Methods: In this study, optimal generic advertising budget intensity index (advertising budget share of production cost was estimated under two different scenarios by using equilibrium replacement model. In equilibrium replacement model, producer surplus are maximized in respect to generic advertising in retail level. According to market where two levels of farm and processing before retail exist and there is trade in farm and retail level, we present different models. Fixed and variable proportion hypothesis is another one. Finally, eight relations are presented for determination of milk generic advertising optimum budget. So, we use data from several resources such as previous studies, national (Iran Static center and international institute (Fao formal data and own estimation. Because there are several estimations in previous studies, we identify some scenarios (in two general scenarios for calculation of milk generic advertising optimum budget. Results and Discussion: Estimation of milk generic advertising optimum budget in scenario 1 shows that in case of one market level, fixed supplies and no trade, optimum budget is 0.4672539 percent. In case of one market level and no trade, optimum

    2015-01-01

    This paper aims to provide an overview of the added societal value of generic medicines beyond their cost-saving potential through reduced prices. In addition, an observational case study will document the impact of generic entry on access to pharmacotherapy in The Netherlands and an illustrative exercise was carried out to highlight the budget impact of generic entry. A narrative literature review was carried out to explore the impact of generic medicines on access to pharmacotherapy, innovation and medication adherence. Data from the Medicines and Medical Devices Information Project database in The Netherlands were used for the case study in which the impact of generic medicine entrance on the budget and the number of users was calculated as an illustrative exercise. Generic medicines have an additional societal value beyond their cost-saving potential through reduced prices. Generic medicines increase access to pharmacotherapy, provide a stimulus for innovation by both originator companies and generic companies and, under the right circumstances, have a positive impact on medication adherence. Generic medicines offer more to society than just their cost-saving potential through reduced prices. As such, governments must not focus only on the prices of generic medicines as this will threaten their long-term sustainability. Governments must therefore act appropriately and implement a coherent set of policies to increase the use of generic medicines.

    2018-01-01

    Inspired by the possibility that the Schwarzschild black hole may not be the unique spherically symmetric vacuum solution to generalizations of general relativity, we consider black holes in pure fourth order higher derivative gravity treated as an effective theory. Such solutions may be of interest in addressing the issue of higher derivative hair or during the later stages of black hole evaporation. Non-Schwarzschild solutions have been studied but we have put earlier results on a firmer footing by finding a systematic asymptotic expansion for the black holes and matching them with known numerical solutions obtained by integrating out from the near-horizon region. These asymptotic expansions can be cast in the form of trans-series expansions which we conjecture will be a generic feature of non-Schwarzschild higher derivative black holes. Excitingly we find a new branch of solutions with lower free energy than the Schwarzschild solution, but as found in earlier work, solutions only seem to exist for black holes with large curvatures, meaning that one should not generically neglect even higher derivative corrections. This suggests that one effectively recovers the nonhair theorems in this context.

    After the expiry of patents for originator medicines, generic medicines can enter the market, and price competition may occur. This process generates savings to the healthcare payer and to patients, but knowledge about the factors affecting price competition in the pharmaceutical market following patent expiry is still limited. This study aimed to investigate the relationship between the market share of generic medicines and the change of the medicine price level in European off-patent markets. Data on medicine volumes and values for 35 active substances were purchased from IMS Health. Ex-manufacturer prices were used, and the analysis was limited to medicines in immediate-release, oral, solid dosage forms. Countries included were Austria, Belgium, Denmark, Germany, France, Italy, the Netherlands, Spain, Sweden and the UK, which constitute a mix of countries with low and high generic medicines market shares. Data were available from June 2002 until March 2007. Market volume has risen in both high and low generic market share countries (+29.27% and +27.40%, respectively), but the cause of the rise is different for the two markets. In low generic market share countries, the rise was caused by the increased use of generic medicines, while in high market share countries, the rise was driven by the increased use of generic medicines and a shift of use from originator to generic medicines. Market value was substantially decreased in high generic market share countries (-26.6%), while the decrease in low generic market share countries was limited (-0.06%). In high generic market share countries, medicine prices dropped by -43.18% versus -21.56% in low market share countries. The extent to which price competition from generic medicines leads to price reductions appears to vary according to the market share of generic medicines. High generic market share countries have seen a larger decrease in medicine prices than low market share countries.

    We present a generic dendritic cell (DC) vaccine strategy for patients with renal cell carcinoma (RCC) based on the use of RNA as a source of multiplex tumor-associated antigens (TAAs). Instead of preparing RNA from tumor tissue of each individual RCC patient, we propose to substitute RNA prepared from a well characterized highly immunogenic RCC cell line (RCC-26 tumor cells) as a generic source of TAAs for loading of DCs. We demonstrate here that efficient RNA transfer can be achieved using lipofection of immature DCs, which are subsequently matured with a cytokine cocktail to express high levels of MHC and costimulatory molecules as well as the chemokine receptor CCR7. Neither RNA itself nor the lipid component impacted on the phenotype or the cytokine secretion of mature DCs. Following RNA loading, DCs derived from HLA-A2-positive donors were able to activate effector-memory cytotoxic T lymphocytes (CTLs) specific for a TAA ligand expressed by the RCC-26 cell line. CTL responses to RNA-loaded DCs reached levels comparable to those stimulated directly by the RCC-26 tumor cells. Furthermore, DCs expressing tumor cell RNA primed naïve T cells, yielding T cell lines with cytotoxicity and cytokine secretion after contact with RCC tumor cells. RCC-26 cell lines are available as good manufacturing practice (GMP)-certified reagents enabling this source of RNA to be easily standardized and adapted for clinical testing. In addition, well defined immune monitoring tools, including the use of RNA expressing B cell lines, are available. Thus, this DC vaccine strategy can be directly compared with an ongoing gene therapy trial using genetically-engineered variants of the RCC-26 cell line as vaccines for RCC patients with metastatic disease.

    Highlights: • Dynamic amplification factor is largely influenced by the DFWs geometry and for the type of bond between DFW and DSM. • DAF were calculated by analyzing the deformed shape and not just looking at the absolute values of displacements. • Detailed transient time history non-linear analysis of an MDUP II electro magnetic event has been carried out. • Cuasi-constant damping ratio of 3% has been considered using a generalized proportional damping model. - Abstract: The purpose of this paper is present an overview of the methodology followed to calculate the dynamic amplification factors applied to the electromagnetic loads acting in the ITER generic port plugs. The methodology used for combining an EM transient event with another kind of load is based in the treated of this dynamic EM event as a static load. As first stage a transient dynamic analysis was performed, at the most demanded electromagnetic event [2], to determine the dynamic response of the port plugs. In the same way, have been solved all the time steps of the dynamic event as static loads, it means that the inertial effect has been neglected. The response of each time-step at the dynamic solution has been compared with the same time-step solved as a static load. For this purpose some control points were positioned along the structure at the most representative locations. The key of these calculations is the understanding of the deformed modes affecting the port plug in order to obtain a reasonable dynamic amplification factors that permit the characterization of these loads in a realistic way and does not derive in a too conservative approach. Additionally, the fundamental frequencies and vibration modes of the generic port plug, requested for the characterization of the damping effects at the structure, were calculated in a complementary modal analysis performed for this aim.

    Highlights: • Reducing atomic masses by 10-fold vastly improves sampling in MD simulations. • CLN025 folded in 4 of 10 × 0.5-μs MD simulations when masses were reduced by 10-fold. • CLN025 folded as early as 96.2 ns in 1 of the 4 simulations that captured folding. • CLN025 did not fold in 10 × 0.5-μs MD simulations when standard masses were used. • Low-mass MD simulation is a simple and generic sampling enhancement technique. - Abstract: CLN025 is one of the smallest fast-folding proteins. Until now it has not been reported that CLN025 can autonomously fold to its native conformation in a classical, all-atom, and isothermal–isobaric molecular dynamics (MD) simulation. This article reports the autonomous and repeated folding of CLN025 from a fully extended backbone conformation to its native conformation in explicit solvent in multiple 500-ns MD simulations at 277 K and 1 atm with the first folding event occurring as early as 66.1 ns. These simulations were accomplished by using AMBER forcefield derivatives with atomic masses reduced by 10-fold on Apple Mac Pros. By contrast, no folding event was observed when the simulations were repeated using the original AMBER forcefields of FF12SB and FF14SB. The results demonstrate that low-mass MD simulation is a simple and generic technique to enhance configurational sampling. This technique may propel autonomous folding of a wide range of miniature proteins in classical, all-atom, and isothermal–isobaric MD simulations performed on commodity computers—an important step forward in quantitative biology.

    1981-01-01

    Large numbers of supports for small-bore, low-temperature pipe are utilized in nuclear power plants. These supports often must meet ASME code and project seismic design requirements. Detailed analysis for each support is time consuming and costly. This paper describes some economical generic methods developed to design and qualify supports for two-inch and smaller pipe operating at temperatures less than 300 0 F (185 0 C), on the Fast Flux Test Facility. Use of standard designs, standard support spacing tables, anchor bolt and baseplate considerations, and field qualification methods are discussed

    The ATLAS Metadata Interface (AMI) is a mature application of more than 15 years of existence. Mainly used by the ATLAS experiment at CERN, it consists of a very generic tool ecosystem for metadata aggregation and cataloguing. We briefly describe the architecture, the main services and the benefits of using AMI in big collaborations, especially for high energy physics. We focus on the recent improvements, for instance: the lightweight clients (Python, Javascript, C++), the new smart task server system and the Web 2.0 AMI framework for simplifying the development of metadata-oriented web interfaces.

    ?This book is an excellent introduction to multiword expressions. It provides a unique, comprehensive and up-to-date overview of this exciting topic in computational linguistics. The first part describes the diversity and richness of multiword expressions, including many examples in several languages. These constructions are not only complex and arbitrary, but also much more frequent than one would guess, making them a real nightmare for natural language processing applications.  The second part introduces a new generic framework for automatic acquisition of multiword expressions from texts.

    2017-10-01

    We study generalized restricted Boltzmann machines with generic priors for units and weights, interpolating between Boolean and Gaussian variables. We present a complete analysis of the replica symmetric phase diagram of these systems, which can be regarded as generalized Hopfield models. We underline the role of the retrieval phase for both inference and learning processes and we show that retrieval is robust for a large class of weight and unit priors, beyond the standard Hopfield scenario. Furthermore, we show how the paramagnetic phase boundary is directly related to the optimal size of the training set necessary for good generalization in a teacher-student scenario of unsupervised learning.

    Previous work has showed that ergosterol and sphingolipids become sorted to secretory vesicles immunoisolated using a chimeric, artificial raft membrane protein as bait. In this study, we have extended this analysis to three populations of secretory vesicles isolated using natural yeast plasma...... a complete lipid overview of the yeast late secretory pathway. We could show that vesicles captured with different baits carry the same cargo and have almost identical lipid compositions; being highly enriched in ergosterol and sphingolipids. This finding indicates that lipid raft sorting is a generic...

    During the probabilistic risk assessment (PRA) for the proposed Yucca Mountain nuclear waste repository, a problem came up that could not be handled by most PRA computer codes. This problem deals with dependencies between sequential events in time. Two similar scenarios that illustrate this problem are LOOP nonrecovery and sequential wearout failures with units of time. The purpose of this paper is twofold: To explain the problem generically, and to show how the PRA code at the INEEL, SAPHIRE, has been modified to solve this problem correctly

    2017-10-01

    We have calculated the non-linear effects of generic fermionic and bosonic hot dark matter components in cosmological N -body simulations. For sub-eV masses, the non-linear power spectrum suppression caused by thermal free-streaming resembles the one seen for massive neutrinos, whereas for masses larger than 1 eV, the non-linear relative suppression of power is smaller than in linear theory. We furthermore find that in the non-linear regime, one can map fermionic to bosonic models by performing a simple transformation.

    Some important spacetimes are conformally flat; examples are the Robertson-Walker cosmological metric, the Einstein-de Sitter spacetime, and the Levi-Civita-Bertotti-Robinson and Mannheim metrics. In this paper we construct generic thin shells in conformally flat spacetime supported by a perfect fluid with a linear equation of state, i.e., p = ωσ. It is shown that, for the physical domain of ω, i.e., 0 < ω ≤ 1, such thin shells are not dynamically stable. The stability of the timelike thin shells with the Mannheim spacetime as the outer region is also investigated. (orig.)

    In this report various forms of the Hamiltonian for particle motion in an accelerator will be derived. Except where noted, the treatment will apply generally to linear and circular accelerators, storage rings, and beamlines. The generic term accelerator will be used to refer to any of these devices. The author will use the usual accelerator coordinate system, which will be introduced first, along with a list of handy formulas. He then starts from the general Hamiltonian for a particle in an electromagnetic field, using the accelerator coordinate system, with time t as independent variable. He switches to a form more convenient for most purposes using the distance s along the reference orbit as independent variable. In section 2, formulas will be derived for the vector potentials that describe the various lattice components. In sections 3, 4, and 5, special forms of the Hamiltonian will be derived for transverse horizontal and vertical motion, for longitudinal motion, and for synchrobetatron coupling of horizontal and longitudinal motions. Hamiltonians will be expanded to fourth order in the variables.

    To evaluate the Malaysian community pharmacists' views on generic medicines. A sample of 1419 Malaysian community pharmacies with resident pharmacists. A cross-sectional nationwide survey using a self-completed mailing questionnaire. Pharmacists' views on generic medicines including issues surrounding efficacy, safety, quality and bioequivalence. Responses were received from 219 pharmacies (response rate 15.4%). Only 50.2% of the surveyed pharmacists agreed that all products that are approved as generic equivalents can be considered therapeutically equivalent with the innovator medicines. Around 76% of respondents indicated that generic substitution of narrow therapeutic index medicines is inappropriate. The majority of the pharmacists understood that a generic medicine must contain the same amount of active ingredient (84.5%) and must be in the same dosage form as the innovator brand (71.7%). About 21% of respondents though that generic medicines are of inferior quality compared to innovator medicines. Most of the pharmacists (61.6%) disagreed that generic medicines produce more side-effects than innovator brand. Pharmacists graduated from Malaysian universities, twinning program and overseas universities were not differed significantly in their views on generic medicines. Additionally, the respondents appeared to have difficulty in ascertaining the bioequivalent status of the marketed generic products in Malaysia. The Malaysian pharmacists' have lack of information and/or trust in the generic manufacturing and/or approval system in Malaysia. This issue should be addressed by pharmacy educators and relevant government agencies.

    Full Text Available A range of factors are believed to exert a negative influence on opinions of physicians about generic drugs.The aim of this study was to survey the opinions of primary care doctors on generics, and determine the factors which may affect them. A questionnaire comprising thirty eight questions was distributed among primary care doctors working in seventy out-patient clinics of the Lodzkie province, Poland, during the period of January 1, 2010 – December 31, 2010. A total of170 of 183 participants completed the survey (average age 48.5; 70.0% women: a 92.9%response rate. While 38.8% of physicians claimed that generics were worse than brand name drugs, 54.1% considered them to be better. However, 36.5% of the doctors did not choose generics for their own use. Two key opinions were identified among the responses concerning the effectiveness of generic drugs: use of generic drugs by the physician (p<0.001, and their opinion that pharmacists do inform patients about generic drugs (p<0.05. Although existing evidence confirms that generic and brand name drugs are equally effective, many physicians doubt this, which prevents them from being used as cost effective drug therapy. In order to increase healthcare savings through the use of generics, these factors should be addressed: for example, convincing a physician to adopt generics for personal use may be an efficient way to support more cost effective treatment of his patients.

    The aim of this project was to evaluate the perceptions, knowledge and attitudes regarding generic medicines. A cross-sectional study, with self administered questionnaires, was conducted to survey consumers visiting pharmacies in four regions of Auckland (North Shore, Waitakere, Central Auckland and South Auckland). Through stratified random sampling, approximately 10% of pharmacies from each region were selected, which turn out to be 30 pharmacies. Every alternate customer coming to the pharmacy, who was eligible to participate in the study, was asked by the researchers to complete the questionnaire. A total of 441 questionnaires were included in the analysis. Different response rates were obtained in different regions of Auckland. Of all respondents, 51.6% had previous knowledge of generic medicines. Pharmacists were the main source of information regarding generic medicines followed by doctors and media. A higher level of education had a direct relationship with having correct knowledge of generics (P = .002). Attitude of participants toward the use of generic medicines was determined by their knowledge of generics, whether it was recommended by a pharmacist and their type of illness. Participants were more prepared to change to a generic for a minor illness (79%) than for a major illness (58.7%). Those who had better knowledge were more likely than those with poor knowledge to say they would to use a generic in major illness (P = .001) as well as minor illness (P < .0001). Previous positive experiences with generics also determined consumers' willingness to use generics. Many consumers have misconceptions regarding generic medicines. Having knowledge about generics and the advice by doctors and pharmacists are key indicators to improve the quality use of generic medicines.

  6. Thermodynamics and kinetics of the glass transition: A generic geometric approach

    International Nuclear Information System (INIS)

    Gutzow, I.; Ilieva, D.; Babalievski, F.; Yamakov, V.

    2000-01-01

    A generic phenomenological theory of the glass transition is developed in the framework of a quasilinear formulation of the thermodynamics of irreversible processes. Starting from one of the basic principles of this science in its approximate form given by de Donder's equation, after a change of variables the temperature dependence of the structural parameter ξ(T), the thermodynamic potentials ΔG(tilde sign)(T), the thermodynamic functions and the time of molecular relaxation τ of vitrifying systems is constructed. In doing so, a new effect in the ΔG(tilde sign)(T) course is observed. The analysis of the higher derivatives of the thermodynamic potential, and especially the nullification of the second derivative of the configurational specific heats ΔC(tilde sign) p (T) of the vitrifying liquid defines glass transition temperature T(tilde sign) g and leads directly to the basic dependence of glass transition kinetics: the Frenkel-Kobeko-Reiner equation. The conditions guaranteeing the fulfillment of this equation specify the temperature dependence of the activation energy U(T,ξ(tilde sign)) for viscous flow and give a natural differentiation of glass formers into fragile and strong liquids. The effect of thermal prehistory on the temperature dependence of both thermodynamic functions and kinetic coefficients is established by an appropriate separation of de Donder's equation.

    Full text: We present generic Bell inequalities for multipartite multi-dimensional systems. They utilize the set of measurements, which are coincident with the generalized version of Greenberger, Horne and Zeilinger (GHZ) paradox. The inequalities that must be satisfied by any local realistic theories are violated by quantum mechanics for even-dimensional multipartite systems. It is also shown that the maximal violation of the inequality is obtained by the generalized GHZ state, which is true multi-body nonseparable state. As a special case for the multipartite two-dimensional systems, it can be shown that the inequality agrees with Bell-Mermin version of inequality. Large sets of variants are shown to naturally emerge from the generic Bell inequalities. We will discuss the particular variants of Bell inequalities that are violated for all the systems including odd-dimensional multipartite systems. Interestingly the variants can be reduced into the Clauser-Horne-Shimony-Holt (CHSH) inequality as well as Ardehali inequality. (author)

    2010-12-08

    In a collaborative study between Los Alamos National Laboratory (LANL) and Sandia National Laboratories (SNL) for the DOE-NE Office of Fuel Cycle Technologies Used Fuel Disposition (UFD) Campaign project, we have conducted preliminary system-level analyses to support the development of a long-term strategy for geologic disposal of high-level radioactive waste. A general modeling framework consisting of a near- and a far-field submodel for a granite GDSE was developed. A representative far-field transport model for a generic granite repository was merged with an integrated systems (GoldSim) near-field model. Integrated Monte Carlo model runs with the combined near- and farfield transport models were performed, and the parameter sensitivities were evaluated for the combined system. In addition, a sub-set of radionuclides that are potentially important to repository performance were identified and evaluated for a series of model runs. The analyses were conducted with different waste inventory scenarios. Analyses were also conducted for different repository radionuelide release scenarios. While the results to date are for a generic granite repository, the work establishes the method to be used in the future to provide guidance on the development of strategy for long-term disposal of high-level radioactive waste in a granite repository.

    A generic reactor model is used to examine the economic viability of generating electricity by magnetic fusion. The simple model uses components that are representative of those used in previous reactor studies of deuterium-tritium-burning tokamaks, stellarators, bumpy tori, reversed-field pinches (RFPs), and tandem mirrors. Conservative costing assumptions are made. The generic reactor is not a tokamak; rather, it is intended to emphasize what is common to all magnetic fusion rectors. The reactor uses a superconducting toroidal coil set to produce the dominant magnetic field. To this extent, it is not as good an approximation to systems such as the RFP in which the main field is produced by a plasma current. The main output of the study is the cost of electricity as a function of the weight and size of the fusion core - blanket, shield, structure, and coils. The model shows that a 1200-MW(e) power plant with a fusion core weight of about 10,000 tonnes should be competitive in the future with fission and fossil plants. Studies of the sensitivity of the model to variations in the assumptions show that this result is not sensitively dependent on any given assumption. Of particular importance is the result that a fusion reactor of this scale may be realized with only moderate advances in physics and technology capabilities

    This poster will give a general description of a generic accounting and reporting software for research reactors. The program has been designed to be a powerful working tool for the operator. The software is designed to be extremely easy to handle and at the same time give the operator the maximal power of searches, calculations and reports that a modern advanced system can produce. The systems are designed to take make the relevant accountancy for the site and perform the reporting to IAEA in Code 10. Generic software for accounting and reporting for research and other smaller facilities is something that has been asked for by many parties. Software like this could be distributed to facilities in need of a powerful accountancy and reporting system for a much lower cost than the systems that is now custom made for these facilities. This will greatly increase the quality of accountancy at these facilities and the quality of the reporting to IAEA and other state offices etc. The software is based on our advanced custom made software series 'STAR' that has been in use in many places for more than a decade with successful use.

    Modern superscalar, out-of-order microprocessors dominate large scale server computing. Monitoring their activity, during program execution, has become complicated due to the complexity of the microarchitectures and their IO interactions. Recent processors have thousands of performance monitoring events. These are required to actually provide coverage for all of the complex interactions and performance issues that can occur. Knowing which data to collect and how to interpret the results has become an unreasonable burden for code developers whose tasks are already hard enough. It becomes the task of the analysis tool developer to bridge this gap. To address this issue, a generic decomposition of how a microprocessor is using the consumed cycles allows code developers to quickly understand which of the myriad of microarchitectural complexities they are battling, without requiring a detailed knowledge of the microarchitecture. When this approach is intrinsically integrated into a performance data analysis tool, it enables software developers to take advantage of the microarchitectural methodology that has only been available to experts. The Generic Optimization Data Analyzer (GOoDA) project integrates this expertise into a profiling tool in order to lower the required expertise of the user and, being designed from the ground up with large-scale object-oriented applications in mind, it will be particularly useful for large HENP codebases

  16. Using generic tool kits to build intelligent systems

    1994-01-01

    The Intelligent Systems and Robots Center at Sandia National Laboratories is developing technologies for the automation of processes associated with environmental remediation and information-driven manufacturing. These technologies, which focus on automated planning and programming and sensor-based and model-based control, are used to build intelligent systems which are able to generate plans of action, program the necessary devices, and use sensors to react to changes in the environment. By automating tasks through the use of programmable devices tied to computer models which are augmented by sensing, requirements for faster, safer, and cheaper systems are being satisfied. However, because of the need for rapid cost-effect prototyping and multi-laboratory teaming, it is also necessary to define a consistent approach to the construction of controllers for such systems. As a result, the Generic Intelligent System Controller (GISC) concept has been developed. This concept promotes the philosophy of producing generic tool kits which can be used and reused to build intelligent control systems.

    Simplified models for transient stability studies are a general requirement for transmission system operators to wind turbine (WTG) manufacturers. Those models must represent the performance of the WTGs for transient stability studies, mainly voltage dips originated by short circuits in the electrical network. Those models are implemented in simulation software as PSS/E, DigSilent or PSLF. Those software platforms allow simulation of transients in large electrical networks with thousands of busses, generators and loads. The high complexity of the grid requires that the models inserted into the grid should be simplified in order to allow the simulations being executed as fast as possible. The development of a model which is simplified enough to be integrated in those complex grids and represent the performance of WTG is a challenge. The IEC TC88 working group has developed generic models for different types of generators, among others for WTGs using doubly fed induction generators (DFIG). This paper will focus in an extension of the models for DFIG WTGs developed in IEC in order to be able to represent the simplified model of DFIG with an active crowbar, which is required to withstand voltage dips without disconnecting from the grid. This paper improves current generic model of Type 3 for DFIG adding a simplified version of the generator including crowbar functionality and a simplified version of the crowbar firing. In addition, this simplified model is validated by correlation with voltage dip field test from a real wind turbine. (orig.)

    Porter's generic strategies characterize organizations in terms of their competitiveness, and are related to the performance of the organization. The aim of this study was to analyze the Porter's generic strategies and their effect on performance in the context of the Slovak hospital industry. Acute care hospitals with more than 30 beds were included into the study. National institutes providing specialized service were excluded from the study. Strategy and performance were evaluated on the basis of self-reported questionnaires, completed by chief administrators of hospitals (total 76 completed questionnaires were obtained, out of 81 distributed, i.e. 94% response rate). The cluster analysis was used for the identification of strategic orientation. Performance differences across strategic groups were tested using multivariate analysis of covariance (MANCOVA). The hierarchical cluster analysis uncovered a four-group taxonomy of hospitals: the group "Focused Cost Leadership" included 33% of hospitals, the group "Stuck-in-the middle" 49%, the group "Wait and See" 13% and the group "Cost leadership" 5%. Significant differences in performance were related to the Porter's pure, or hybrid strategies, respectively. In terms of industry evolution, the Slovak hospital industry could be characterized as fragmented, having a large number of small and medium size mainly state owned hospitals, with absence of market leaders, and with high exit barriers (mainly social and political) that hold back consolidation. (Tab. 1, Ref. 35.).

    The aim of the study was to examine the use of Porter's generic strategies and their effect on performance in the context of the Slovak hospital industry. Using mail survey the study first identified the natural taxonomy of four strategic types of Slovak hospitals, based on their use of Porter's generic strategies in pure form and in combination. Next the study examined whether different strategic types were associated with different levels of organisational performance, while controlling for such variables as size and location, which have been argued to influence the hospital performance. The findings indicate that hospitals which follow a "stuck-in-the-middle" strategy, in general, have superior performance on all used performance measures, while hospitals that place only low emphasis on cost leadership, differentiation and focus, labelled "wait and see" in this study, perform the poorest. The study concludes that the research provided body of knowledge relevant for the Slovak hospital industry, that may be used by hospital managers in the strategy formulation process as well as by the researches in exploring the influence of different contingencies on hospitals' strategic orientation.

    We study (2,2) and (4,4) supersymmetric theories with superspace higher derivatives in two dimensions. A characteristic feature of these models is that they have several different vacua, some of which break supersymmetry. Depending on the vacuum, the equations of motion describe different propagating degrees of freedom. Various examples are presented which illustrate their generic properties. As a by-product we see that these new vacua give a dynamical way of generating non-linear realizations. In particular, our 2D (4,4) example is the dimensional reduction of a 4D N=2 model, and gives a new way for the spontaneous breaking of extended supersymmetry.

    The UK Nuclear Decommissioning Authority Radioactive Waste Management Directorate (NDA RWMD, formerly Nirex UK Ltd), has played a leading role in establishing knowledge on geological disposal of radioactive waste in the UK. In 2001, a study was commissioned of the potential impact of releases of radio-nuclides from a generic repository on plants and animals). More recently, the NDA commissioned Enviros Consulting to report on developments in policy and in approaches for assessing impacts of radioactivity on non-human biota, that have occurred since the previous study. A trial application of the ERICA assessment tool, to reassess the impact of releases from a generic deep repository using similar source data as used previously (Nirex, 2003), formed part of this work. This paper summarizes the results of the reassessment exercise; key differences between the two assessments are identified and explored. The applicability and capabilities of the ERICA tool to assessments of releases from a waste repository are discussed and priorities for future work are identified. Conclusions: The peak activity concentrations predicted to arise from releases from a generic repository would not lead to a significant increase in environmental risk. Indeed, a substantial proportion of the calculated dose rates are due to natural series radio-nuclides at concentrations that are well below typical background levels. In the previous study, the highest (weighted) absorbed dose rate in an aquatic system was predicted to be around 6.5 micoGy h -1 , which is of the same order of magnitude as those predicted in the current study; the significance of the contribution of natural series radionuclides is also common to both studies. However, previously, the authors concluded that it was not possible to undertake a detailed assessment for the terrestrial system, due to the paucity of data on concentration ratios.

    Escalating pharmaceutical costs have become a global challenge for both governments and patients. Generic substitution is one way of decreasing these costs. The aim of this study was to investigate factors associated with patients' choice between generic drugs and innovator drugs. The survey was conducted in June 2013, 1000 people from across Poland were chosen as a representative population sample. The outcome (a preference for generics/a preference for innovator pharmaceuticals/no preference) was modeled by multinomial logistic regression, adjusted for several variables describing patients' sensitivity to selected generic features (price, brand, and country of origin), to third-party opinions about generics (information on generics in the mass media, opinions of health professionals (i.e. physicians, pharmacists), relatives/friends), as well as patients' personal experiences and income per household. The results supported the predictive capacity of most independent variables (except for patient sensitivity to the country of origin and to the information on generics in the mass media), denoting patients' preferences toward generic substitution. Patient sensitivity to recommendations by physicians, generic brand, and household income were the strongest predictors of the choice between generic and innovator pharmaceuticals (P brand or their physician's opinion, as well as in respondents who were sensitive to recommendations by pharmacists or attached a greater value to a past experience with generics (their own experience or that of relatives/friends). In consideration of the foregoing, awareness-raising campaigns may be recommended, supported by a variety of systemic solutions and tools to encourage generic substitution.

    Because generic medications are less expensive than brand-name medications, government and private insurers have encouraged and/or mandated the use of generics. This study aimed at evaluating perceptions about generic medications among English-speaking women of childbearing age currently enrolled in U.S. TennCare (Medicaid). We recruited a convenience sample of patients from the waiting room of a primary care/gynecology health clinic, with 80% recruitment rate among those approached. We orally administered a 25-item questionnaire to gather sociodemographic information and to assess beliefs regarding the efficacy, safety, cost, and preferences for personal use of generic medications. The average age of the women (n=172) was 28.8 ± 6.4 years, and most were white (82.0%) and currently married (58.1%). Nearly one-fifth (19.2%) had not completed high school. Most women believed that generic medications were less expensive (97.6%) and better value (60.5%) than brand-name medications, but only 45.3% preferred to take generics themselves. About a quarter (23.3%) believed that brand-name medications were more effective than generics, whereas 13.4% believed that generics caused more side effects. Few women reported that their doctor (29.7%) and/or pharmacist (35.5%) had ever talked to them about taking generics. Awareness of the benefits of generics did not equal preferences for personal use of generics among this sample of women enrolled in U.S. TennCare. Furthermore, women reported that providers-both physicians and pharmacists-infrequently discussed generic substitution with them. Copyright © 2012 Elsevier Inc. All rights reserved.

    The objective of this paper was to undertake a narrative review of the literature regarding strategies and interventions promoting the acceptance and uptake of generic medicines. A literature search was performed between November 2011 and January 2012 to identify published full text original research articles documenting interventions to promote the use of generic medicines. Keywords used were: "generic medicine", "generic drug", "intervention", "promotion", "acceptance", "uptake", "generic/therapeutic substitution" and their related root words. The electronic databases comprised of Embase (1980 - present), Google, Google Scholar, Medline (1948 - present), PubMed, Science Direct, Scopus, Springer Link and The Cochrane Library. An interpretative narrative synthesis was undertaken and emergent themes analysed and reported. Eighteen studies were included in the final analysis. There were seven main themes which including; education, financial incentives, advertising to promote generic medicines, free generic medicine trials, administrative forms and medicines use review (MUR). These themes were further classified into subthemes. Education was subdivided into consumer and physician education. Financial incentives included the influence of financial incentives on both consumers and physicians. The subthemes in the financial incentives category included the changes in co-payment for consumers, reward payment for physicians and fund-holding schemes. Advertising included the sub-themes of print media and the use of anthropomorphic images, while free generic medicines trial was made up of free vouchers for generic medicines and generic medicines sampling system. The studies have mixed results; some interventions in some settings were useful, while others were not. Not all interventions consistently improved the uptake of generic medicines. There was limited literature available and further work is required to develop a range of interventions to support the uptake of generic

    Full Text Available ABSTRACT OBJECTIVE The objective of this study is to identify factors associated with the preference for purchasing generic drugs in a medium-sized municipality in Southern Brazil. METHODS We have analyzed data from a population-based cross-sectional study conducted in 2012 with a sample of 2,856 adults (≥ 20 years old. The preference for purchasing generic drugs was the main outcome. The explanatory variables were the demographic and socioeconomic variables. Statistical analyses included Poisson regressions. RESULTS The preference for purchasing generic drugs was 63.2% (95%CI 61.4–64.9. The variables correlated with this preference in the fully adjusted models were: male (prevalence ratio [PR] = 1.08; 95%CI 1.03–1.14, age of 20–39 years (PR = 1.10; 95%CI 1.02–1.20, low socioeconomic status (PR = 1.15; 95%CI 1.03–1.28, and good knowledge about generic drugs (PR= 4.66; 95%CI 2.89–7.52. Among those who preferred to purchase generic drugs, 55.1% have reported accepting to replace the prescribed drug (if not a generic with the equivalent generic drug. Another correlate of the preference for purchasing generic drugs was because individuals consider their quality equivalent to reference medicines (PR = 2.15; 95%CI 1.93–2.41. CONCLUSIONS Knowledge about generic drugs was the main correlate of the preference for purchasing generic drugs. The greater the knowledge or positive perception about generic drugs, the greater is the preference to purchase them. Therefore, educational campaigns for healthcare professionals and consumers appear to be the best strategy for expanding the use of generic drugs in Brazil.

    Full Text Available Survey data show that the use of generic medicines in Indonesia is relatively very small, which only amounted 7%. This is due to lack of knowledge and poor perceptions towards generic medicines. Knowledge level and perceptions towards generic medicines are inflenced by community characteristics and information resource regarding generic medicines. The aim of this study was to determine the association between community characteristic and information resources with knowledge level and perception towards generic medicines. This study was an analytical survey with cross-sectional descriptive approach on 142 selected respondents who were fulfi inclusion and exclusion criteria. This study was conducted in June 2014 at several randomly selected locations on Singkawang City. The study show that 76 respondents (53.5% had inadequate knowledge and 123 respondents (86.6% had a good perception towards generic medicines. There is signifiant relationship between ethnicity (p=0.000 and information resources (p=0.009 with knowledge level regarding generic medicines at signifiance level of p<0.05. Although good perceptions were noted among the respondents, widespread dissemination of information regarding generic medicines should be continued to increase generic medicines used.

    2008-07-01

    The aim of this study was to evaluate the quality of 31 commercially available generic formulations of docetaxel purchased in 14 countries by comparing their docetaxel content, impurity levels and pH versus those of the proprietary product Taxotere (Tx). Generic formulations were purchased in 14 countries in Asia, Africa, the Middle East and Latin America. Levels of docetaxel and impurities (chromatographic peaks above 0.05%) were obtained for each sample using reverse-phase liquid chromatography with ultraviolet detection. The pH of aqueous solutions of generic docetaxel formulations and Tx was also measured. A global evaluation of quality was conducted on each product using a multicriteria desirability analysis based on standards defined by the International Conference on Harmonisation guidelines and the US Pharmacopeia paclitaxel injection monograph. Most generic formulations contained a lower than expected amount of docetaxel and/or a high level of impurities: 21 generic docetaxel formulations had an average mass of docetaxel that was generic docetaxel formulations had a total impurity content of >3.0%, almost twice the level of impurities in Tx 20 mg. In total, 33 impurities not present in Tx were detected in the generic samples. Desirability analysis demonstrated that none of the generic docetaxel formulations had composition characteristics similar to those of Tx. This study demonstrated that from an analytical point of view, 90% of the generic docetaxel formulations evaluated contained insufficient active drug, high levels of impurities or both. This has the potential to affect both efficacy and safety of the drug.

    The increasing requirement to dramatically reduce the cost of mission operations led to increased emphasis on automation technology. The expert system technology used at the Goddard Space Flight Center (MD) is currently being applied to the automation of spacecraft control center activities. The generic inferential executor (GENIE) is a tool which allows pass automation applications to be constructed. The pass script templates constructed encode the tasks necessary to mimic flight operations team interactions with the spacecraft during a pass. These templates can be configured with data specific to a particular pass. Animated graphical displays illustrate the progress during the pass. The first GENIE application automates passes of the solar, anomalous and magnetospheric particle explorer (SAMPEX) spacecraft.

    Performance of quantum process estimation is naturally limited by fundamental, random, and systematic imperfections of preparations and measurements. These imperfections may lead to considerable errors in the process reconstruction because standard data-analysis techniques usually presume ideal devices. Here, by utilizing generic auxiliary quantum or classical correlations, we provide a framework for the estimation of quantum dynamics via a single measurement apparatus. By construction, this approach can be applied to quantum tomography schemes with calibrated faulty-state generators and analyzers. Specifically, we present a generalization of the work begun by M. Mohseni and D. A. Lidar [Phys. Rev. Lett. 97, 170501 (2006)] with an imperfect Bell-state analyzer. We demonstrate that for several physically relevant noisy preparations and measurements, classical correlations and a small data-processing overhead suffice to accomplish the full system identification. Furthermore, we provide the optimal input states whereby the error amplification due to inversion of the measurement data is minimal.

    1997-01-01

    This paper documents the radiation analysis performed for the storage area of a generic Centralized Interim Storage Facility (CISF) for commercial spent nuclear fuel (SNF). The purpose of the analysis is to establish the CISF Protected Area and Restricted Area boundaries by modeling a representative SNF storage array, calculating the radiation dose at selected locations outside the storage area, and comparing the results with regulatory radiation dose limits. The particular challenge for this analysis is to adequately model a large (6000 cask) storage array with a reasonable amount of analysis time and effort. Previous analyses of SNF storage systems for Independent Spent Fuel Storage Installations at nuclear plant sites (for example in References 5.1 and 5.2) had only considered small arrays of storage casks. For such analyses, the dose contribution from each storage cask can be modeled individually. Since the large number of casks in the CISF storage array make such an approach unrealistic, a simplified model is required

    The huge demand for situational and ad-hoc applications desired by the mass of business end users led to a new kind of Web applications, well-known as Enterprise Mashups. Users with no or limited programming skills are empowered to leverage in a collaborative manner existing Mashup components by combining and reusing company internal and external resources within minutes to new value added applications. Thereby, Enterprise Mashup environments interact as intermediaries to match the supply of providers and demand of consumers. By following the design science approach, we propose an interaction phase model artefact based on market transaction phases to structure required intermediary features. By means of five case studies, we demonstrate the application of the designed model and identify three generic business model types for Enterprise Mashups intermediaries (directory, broker, and marketplace). So far, intermediaries following a real marketplace business model don’t exist in context of Enterprise Mashups and require further research for this emerging paradigm.

    For metrology under optical microscopes, lens distortion is the dominant source of error. Previous distortion models and correction methods mostly rely on the assumption that parametric distortion models require a priori knowledge of the microscopes' lens systems. However, because of the numerous optical elements in a microscope, distortions can be hardly represented by a simple parametric model. In this paper, a generic distortion model considering both symmetric and asymmetric distortions is developed. Such a model is obtained by using radial basis functions (RBFs) to interpolate the radius and distortion values of symmetric distortions (image coordinates and distortion rays for asymmetric distortions). An accurate and easy to implement distortion correction method is presented. With the proposed approach, quantitative measurement with better accuracy can be achieved, such as in Digital Image Correlation for deformation measurement when used with an optical microscope. The proposed technique is verified by both synthetic and real data experiments.

  20. Generic vortex modelling for horizontal-axis wind turbines

    Energy Technology Data Exchange (ETDEWEB)

    Wood, D.H.

    2002-07-01

    This paper describes a generic free-wake calculation of wind turbine wakes. The expanding, helical, tip vortices are represented by a sequence of straight segments, the blades are modelled as lines of constant bound vorticity, and the hub vortices lie along the axis of rotation. It is shown that this model is consistent with the one-dimensional analysis that leads to the Lanchester-Betz limit, in that the velocity in the far-wake is uniform with radius. Particular attention is paid to turbines operating above the Lanchester-Betz limit. It is shown that the usual relationship between the velocity through the blades and in the far-wake breaks down when there is significant wake expansion, and an empirical modification to that relation is presented. For highly expanding wakes, the dynamics of the turbine depend sensitively on the behaviour of the tip vortices. (author)

  1. Complexity of generic biochemical circuits: topology versus strength of interactions

    Science.gov (United States)

    Tikhonov, Mikhail; Bialek, William

    2016-12-01

    The historical focus on network topology as a determinant of biological function is still largely maintained today, illustrated by the rise of structure-only approaches to network analysis. However, biochemical circuits and genetic regulatory networks are defined both by their topology and by a multitude of continuously adjustable parameters, such as the strength of interactions between nodes, also recognized as important. Here we present a class of simple perceptron-based Boolean models within which comparing the relative importance of topology versus interaction strengths becomes a quantitatively well-posed problem. We quantify the intuition that for generic networks, optimization of interaction strengths is a crucial ingredient of achieving high complexity, defined here as the number of fixed points the network can accommodate. We propose a new methodology for characterizing the relative role of parameter optimization for topologies of a given class.

    Cells move differently on substrates with different rigidities: the persistence time of their motion is higher on stiffer substrates. We show that this behavior—in and of itself—results in a net flux of cells directed up a soft-to-stiff gradient. Using simple random walk models with varying persistence and stochastic simulations, we characterize the propensity to move in terms of the durotactic index also measured in experiments. A one-dimensional model captures the essential features and highlights the competition between diffusive spreading and linear, wavelike propagation. Persistence-driven durokinesis is generic and may be of use in the design of instructive environments for cells and other motile, mechanosensitive objects.

    Csank, Jeffrey; May, Ryan D.

    2010-01-01

    This paper describes the control algorithms and control design process for a generic commercial aircraft engine simulation of a 40,000 lb thrust class, two spool, high bypass ratio turbofan engine. The aircraft engine is a complex nonlinear system designed to operate over an extreme range of environmental conditions, at temperatures from approximately -60 to 120+ F, and at altitudes from below sea level to 40,000 ft, posing multiple control design constraints. The objective of this paper is to provide the reader an overview of the control design process, design considerations, and justifications as to why the particular architecture and limits have been chosen. The controller architecture contains a gain-scheduled Proportional Integral controller along with logic to protect the aircraft engine from exceeding any limits. Simulation results illustrate that the closed loop system meets the Federal Aviation Administration s thrust response requirements

    The Kuramoto–Sakaguchi system of coupled phase oscillators, where interaction between oscillators is determined by a single harmonic of phase differences of pairs of oscillators, has very simple emergent dynamics in the case of identical oscillators that are globally coupled: there is a variational structure that means the only attractors are full synchrony (in-phase) or splay phase (rotating wave/full asynchrony) oscillations and the bifurcation between these states is highly degenerate. Here we show that nonpairwise coupling—including three and four-way interactions of the oscillator phases—that appears generically at the next order in normal-form based calculations can give rise to complex emergent dynamics in symmetric phase oscillator networks. In particular, we show that chaos can appear in the smallest possible dimension of four coupled phase oscillators for a range of parameter values.

    2008-01-01

    We reconsider spherically symmetric black hole solutions in Einstein-Aether theory with the condition that this theory has identical parametrized post-Newtonian parameters as those for general relativity, which is the main difference from the previous research. In contrast with previous study, we allow superluminal propagation of a spin-0 Aether-gravity wave mode. As a result, we obtain black holes having a spin-0 'horizon' inside an event horizon. We allow a singularity at a spin-0 horizon since it is concealed by the event horizon. If we allow such a configuration, the kinetic term of the Aether field can be large enough for black holes to be significantly different from Schwarzschild black holes with respect to Arnowitt-Deser-Misner mass, innermost stable circular orbit, Hawking temperature, and so on. We also discuss whether or not the above features can be seen in more generic vector-tensor theories

    1996-04-01

    Many industries are switching from analog equipment to digital equipment. This change has become desirable because digital devices have become cost-effective, easily available, highly reliable, easy to qualify and easy to test and replace when needed. The nuclear power industry is beginning to upgrade some of its instrumentation and control equipment from an analog design to digital design. A digital application specific integrated circuit (ASIC) device can be designed to perform the same functions as performed by analog modules. However, the ASIC must be designed for cost-effective testability and qualification. This report provides generic guidelines for designing cost-effective methods for testing and characterizing ASIC devices to accomplish qualification

    This report supplements the treatment of waste management issues provided in the Generic Environmental Statement on the use of recycle plutonium in mixed oxide fuel in light water cooled reactors (GESMO, NUREG-0002). Three recycle and three no-recycle options are described in this document. Management of the radioactive wastes that would result from implementation of either type of fuel cycle alternative is discussed. For five of the six options, wastes would be placed in deep geologic salt repositories for which thermal criteria are considered. Radiation doses to the workers at the repositories and to the general population are discussed. The report also covers the waste management schedule, the land and salt commitments, and the economic costs for the management of wastes generated

  9. A generic algorithm for constructing hierarchical representations of geometric objects

    1995-01-01

    For a number of years, robotics researchers have exploited hierarchical representations of geometrical objects and scenes in motion-planning, collision-avoidance, and simulation. However, few general techniques exist for automatically constructing them. We present a generic, bottom-up algorithm that uses a heuristic clustering technique to produced balanced, coherent hierarchies. Its worst-case running time is O(N 2 logN), but for non-pathological cases it is O(NlogN), where N is the number of input primitives. We have completed a preliminary C++ implementation for input collections of 3D convex polygons and 3D convex polyhedra and conducted simple experiments with scenes of up to 12,000 polygons, which take only a few minutes to process. We present examples using spheres and convex hulls as hierarchy primitives

    Beck, Aaron T; Haigh, Emily A P

    2014-01-01

    For over 50 years, Beck's cognitive model has provided an evidence-based way to conceptualize and treat psychological disorders. The generic cognitive model represents a set of common principles that can be applied across the spectrum of psychological disorders. The updated theoretical model provides a framework for addressing significant questions regarding the phenomenology of disorders not explained in previous iterations of the original model. New additions to the theory include continuity of adaptive and maladaptive function, dual information processing, energizing of schemas, and attentional focus. The model includes a theory of modes, an organization of schemas relevant to expectancies, self-evaluations, rules, and memories. A description of the new theoretical model is followed by a presentation of the corresponding applied model, which provides a template for conceptualizing a specific disorder and formulating a case. The focus on beliefs differentiates disorders and provides a target for treatment. A variety of interventions are described.

    Simulations of deep geologic disposal of nuclear waste in a generic shale formation showcase Geologic Disposal Safety Assessment (GDSA) Framework, a toolkit for repository performance assessment (PA) whose capabilities include domain discretization (Cubit), multiphysics simulations (PFLOTRAN), uncertainty and sensitivity analysis (Dakota), and visualization (Paraview). GDSA Framework is used to conduct PAs of two generic repositories in shale. The first considers the disposal of 22,000 metric tons heavy metal of commercial spent nuclear fuel. The second considers disposal of defense-related spent nuclear fuel and high level waste. Each PA accounts for the thermal load and radionuclide inventory of applicable waste types, components of the engineered barrier system, and components of the natural barrier system including the host rock shale and underlying and overlying stratigraphic units. Model domains are half-symmetry, gridded with Cubit, and contain between 7 and 22 million grid cells. Grid refinement captures the detail of individual waste packages, emplacement drifts, access drifts, and shafts. Simulations are run in a high performance computing environment on as many as 2048 processes. Equations describing coupled heat and fluid flow and reactive transport are solved with PFLOTRAN, an open-source, massively parallel multiphase flow and reactive transport code. Additional simulated processes include waste package degradation, waste form dissolution, radioactive decay and ingrowth, sorption, solubility, advection, dispersion, and diffusion. Simulations are run to 106 y, and radionuclide concentrations are observed within aquifers at a point approximately 5 km downgradient of the repository. Dakota is used to sample likely ranges of input parameters including waste form and waste package degradation rates and properties of engineered and natural materials to quantify uncertainty in predicted concentrations and sensitivity to input parameters.

    Highlights: • Short overview of the models included in the ASTEC MCCI module. • MEDICIS/CPA coupled calculations for a generic CANDU6 reactor. • Two cases taking into account different pool/concrete interface models. - Abstract: In case of a hypothetical severe accident in a nuclear power plant, the corium consisting of the molten reactor core and internal structures may flow onto the concrete floor of containment building. This would cause an interaction between the molten corium and the concrete (MCCI), in which the heat transfer from the hot melt to the concrete would cause the decomposition and the ablation of the concrete. The potential hazard of this interaction is the loss of integrity of the containment building and the release of fission products into the environment due to the possibility of a concrete foundation melt-through or containment over-pressurization by the gases produced from the decomposition of the concrete or by the inflammation of combustible gases. In the safety assessment of nuclear power plants, it is necessary to know the consequences of such a phenomenon. The paper presents an example of application of the ASTECv2 code to a generic CANDU6 reactor. This concerns the thermal-hydraulic behaviour of the containment during molten core–concrete interaction in the reactor vault. The calculations were carried out with the help of the MEDICIS MCCI module and the CPA containment module of ASTEC code coupled through a specific prediction–correction method, which consists in describing the heat exchanges with the vault walls and partially absorbent gases. Moreover, the heat conduction inside the vault walls is described. Two cases are presented in this paper taking into account two different heat transfer models at the pool/concrete interface and siliceous concrete. The corium pool configuration corresponds to a homogeneous configuration with a detailed description of the upper crust.

  16. Extension algorithm for generic low-voltage networks

    Marwitz, S.; Olk, C.

    2018-02-01

    Distributed energy resources (DERs) are increasingly penetrating the energy system which is driven by climate and sustainability goals. These technologies are mostly connected to low- voltage electrical networks and change the demand and supply situation in these networks. This can cause critical network states. Network topologies vary significantly and depend on several conditions including geography, historical development, network design or number of network connections. In the past, only some of these aspects were taken into account when estimating the network investment needs for Germany on the low-voltage level. Typically, fixed network topologies are examined or a Monte Carlo approach is used to quantify the investment needs at this voltage level. Recent research has revealed that DERs differ substantially between rural, suburban and urban regions. The low-voltage network topologies have different design concepts in these regions, so that different network topologies have to be considered when assessing the need for network extensions and investments due to DERs. An extension algorithm is needed to calculate network extensions and investment needs for the different typologies of generic low-voltage networks. We therefore present a new algorithm, which is capable of calculating the extension for generic low-voltage networks of any given topology based on voltage range deviations and thermal overloads. The algorithm requires information about line and cable lengths, their topology and the network state only. We test the algorithm on a radial, a loop, and a heavily meshed network. Here we show that the algorithm functions for electrical networks with these topologies. We found that the algorithm is able to extend different networks efficiently by placing cables between network nodes. The main value of the algorithm is that it does not require any information about routes for additional cables or positions for additional substations when it comes to estimating

  17. Task Action Plans for generic activities: Category A

    1978-10-01

    The document contains listings of generic technical activities as identified and placed in priority categories by the Office of Nuclear Reactor Regulation (NRR). In addition, it contains definitions of Priority Categories A, B, C, and D and copies of forty approved Task Action Plans for Category A activites. Problem Descriptions for the Category B, C and D tasks are contained in NUREG--0471. This material was developed within the context of NRR's Program for the Resolution of Generic Issues Related to Nuclear Power Plants. As part of this program, the assignment of identified issues to priority categories and the approval of Task Action Plans were made by NRR's Technical Activities Steering Committee, chaired by the Deputy Director, NRR. The original document was published in November 1977. In December 1977 it was updated to add the Task Action Plan for Task No. A-17, Systems Interactions in Nuclear Power Plants. This update adds Task Action Plans for Tasks A-13, A-18, A-21, A-22, A-32, A-37, A-38 and A-40. Task A-41 has been included in Task A-40. In addition, as part of this update, the following changes were made to each Task Action Plan (with the exception of the Task Action Plan for Task A-9): (1) a title page was added that includes information such as Lead NRR Organization, Lead Supervisor, Task Manager, Applicability, and Projected Completion Date; (2) detailed schedule information was deleted; and (3) a new Section 3 entitled Basis for Continued Plant Operation and Licensing Pending Completion of Task was added. These changes represent general reformatting and the addition or deletion of certain general types of information. Some substantive revisions were made to several of the plans, however, a general revision of all of the plans was not undertaken at this time

  18. Developing a sustainable bioprocessing strategy based on a generic feedstock.

    Based on current average yields of wheat per hectare and the saccharide content of wheat grain, it is feasible to produce wheat-based alternatives to many petrochemicals. However, the requirements in terms of wheat utilization would be equivalent to 82% of current production if intermediates and primary building blocks such as ethylene, propylene, and butadiene were to be produced in addition to conventional bioproducts. If only intermediates and bioproducts were produced this requirement would fall to just 11%, while bioproducts alone would require only 7%. These requirements would be easily met if the global wheat yield per hectare of cultivated land was increased from the current average of 2.7 to 5.5 tonnes ha(-1) (well below the current maximum). Preliminary economic evaluation taking into account only raw material costs demonstrated that the use of wheat as a generic feedstock could be advantageous in the case of bioproducts and specific intermediate petrochemicals. Gluten plays a significant role considering the revenue occurring when it is sold as a by-product. A process leading to the production of a generic fermentation feedstock from wheat has been devised and evaluated in terms of efficiency and economics. This feedstock aims at providing a replacement for conventional fermentation media and petrochemical feedstocks. The process can be divided into four major stages--wheat milling; fermentation of whole wheat flour by A. awamori leading to the production of enzymes and fungal cells; glucose enhancement via enzymatic hydrolysis of flour suspensions; and nitrogen/micronutrient enhancement via fungal cell autolysis. Preliminary costings show that the operating cost of the process depends on plant capacity, cereal market price, presence and market value of added-value by-products, labour costs, and mode of processing (batch or continuous).

    Generics have the potential to contain drug therapy costs; successful implementation of generic substitution policy largely depends on consumers' willingness to choose generics. This study aims to analyse the opinions, experiences and preferences of Polish patients towards generic medicines. The study was performed in Poland. The survey was conducted in June 2013 by means of face-to-face interviews. Respondents were drawn from the general population according to a population structure. The study covered a representative sample of 1,000 Poles; the results can be generalized to apply to the Polish population at large. Fifty-two percent of respondents declared to be more often choosing generics, twenty-three percent did not have any specific preferences, and twenty-five percent were more willing to choose brand-name medicines. Past experience with cheaper generic medicines, secondary or lower education, low income and residence in specific regions of Poland were all significantly associated with an increased willingness to choose generics. Respondents' attitudes towards generics were mostly influenced by the opinions of doctors and pharmacists. According to respondents, attitudes towards generics among doctors, pharmacists, family and friends, and in the mass media were mostly positive. There was no relationship between the preference of respondents for generics and factors such as their age, life stage, gender, household size or urban/rural locality. As a result of substituting a brand-name drug with its generic equivalent, 72 % of respondents reported that they had not noticed any difference in drug effectiveness; 21 % had experienced a reduced effectiveness of treatment or increased side effects at least once; and 7 % claimed the generic worked better. The majority of respondents who used cheaper substitutes claimed that generics represented good or very good quality. The study demonstrates that, when choosing medicines, Poles rely mainly on the opinions of their

    To assess patient acceptance of the substitution of brand-name drugs for generic equivalents in the context of repeat prescriptions for chronic diseases. A prospective multicenter study of drug use was performed. Of the 31 centers included in the study, 8 were randomized to the intervention group and 23 to the control group. For 1 year, patients in the intervention group who visited the center to collect repeat prescriptions received verbal and written information on the advantages and disadvantages of generic and brand name drugs. Data on the number of patients taking brand-name drugs for which generic equivalents were available, as well as the reasons and variables related to refusal of generic drugs (age, gender, education, primary care centre, general practitioner, type of drug and total number of repeat prescriptions) were collected. The percentage of generic drugs among the total number of drugs prescribed was calculated at 2-monthly intervals. A total of 98.9% of the 4620 patients in the intervention group agreed to change to a generic formulation. The percentage of patients accepting generic drugs was significantly associated with the primary care centre, the class of drug, doctors' influence, and patient satisfaction with the drug. Generic prescriptions represented 5.9% in the intervention practices compared with 2.8% in controls. After the intervention, and before the application of reference prices, the percentages were 6.7% and 3.9%, respectively. Immediately after application of the reference prices, the percentages were 8.6% and 6.3%, respectively. Direct patient education is an effective strategy in increasing the prescription of generic equivalents. General practitioners' motivation and knowledge of generic drugs influenced their use. The application of reference prices increased the use of generic equivalents.

    Because of their lower cost, healthcare systems recommend physicians to prefer generic products, rather than brand-name medicaments. There is then considerable interest and debate concerning safety and effectiveness of generic products. Few studies have compared patients treated with brand-name and generic drugs for adherence to treatment, with somewhat inconsistent results. The primary objective of this study was to compare the risk of discontinuing antihypertensive drug therapy in patients treated with generic or brand-name agents. The 101,618 beneficiaries of the Healthcare system of Lombardy, Italy, aged 18 years or older who were newly treated on monotherapy with antihypertensive generic or brand-name drugs during 2008, were followed until the earliest date among those of the occurrence of treatment discontinuation to whatever antihypertensive drug therapy (outcome), or censoring (death, emigration, 12 months after treatment initiation). Hazard ratios of discontinuation associated with starting on generic or brand-name products (intention-to-treat analysis), and incidence rate ratio of discontinuation during periods on generic and brand-name products (as-treated analysis) were respectively estimated from a cohort and self-controlled case series analyses. Patients who started on generics did not experience a different risk of discontinuation compared with those starting on brand-name agents (hazard ratio: 1.00; 95% confidence interval 0.98-1.02). Discontinuation did not occur with different rates during periods covered by generics or brand-name agents (incidence rate ratio: 1.01; 95% confidence interval 0.96-1.11) within the same individuals. A number of sensitivity and subgroup analyses confirmed the robustness of these findings. Generic products are not responsible for the high rate of discontinuation from antihypertensive drug therapy. Assuming therapeutic equivalence, clinical implication is of prescribing generic drug therapies.

    Alberta, quickly followed by other Canadian provinces, has introduced a new pricing model for generic drugs, in which prices are inversely related to the number of generic manufacturers of the drug. This paper examines the rationale for the new policy. Copyright © 2015 Longwoods Publishing.

    Branding medication with a known pharmaceutical company name or product name bestows on the drug an added assurance of authenticity and effectiveness compared to a generic preparation. This study examined the impact of brand name and generic labeling on medication effectiveness and side effects. 87 undergraduate students with frequent headaches took part in the study. Using a within-subjects counterbalanced design, each participant took tablets labeled either as brand name "Nurofen" or "Generic Ibuprofen" to treat each of 4 headaches. In reality, half of the tablets were placebos, and half were active ibuprofen (400 mg). Participants recorded their headache pain on a verbal descriptor and visual analogue scale prior to taking the tablets, and again 1 hour afterward. Medication side effects were also reported. Pain reduction following the use of brand name labeled tablets was similar in active ibuprofen or a placebo. However, if the tablets had a generic label, placebo tablets were significantly less effective compared to active ibuprofen. Fewer side effects were attributed to placebo tablets with brand name labeling compared to the same placebo tablets with a generic label. Branding of a tablet appears to have conferred a treatment benefit in the absence of an active ingredient, while generic labeled tablets were substantially less effective if they contained no active ingredient. Branding is also associated with reduced attribution of side effects to placebo tablets. Future interventions to improve perceptions of generics may have utility in improving treatment outcomes from generic drugs. (c) 2016 APA, all rights reserved).

    The objective of generic drug policies in most countries is defined from a disinvestment perspective: reduction in expenditures without compromising health outcomes. However, in countries with restricted access of patients to original patented drugs, the objective of generic drug policies can also be defined from an investment perspective: health gain by improved patient access without need for additional health budget. This study examines the investment aspect of generic medicines by analyzing clopidogrel utilization in European countries between 2004 and 2014 using multilevel panel data models. We find that clopidogrel consumption was strongly affected by affordability constraints before the generic entry around 2009, but this effect decayed by 2014. After controlling for other variables, utilization had a substantially larger trend increase in lower-income European countries than in the higher-income ones. Generic entry increased clopidogrel consumption only in lower- and average-income countries but not in the highest-income ones. An earlier generic entry was associated with a larger effect. The case of clopidogrel indicates that the entrance of generics may increase patient access to effective medicines, most notably in lower-income countries, thereby reducing inequalities between European patients. Policymakers should also consider this investment aspect of generic medicines when designing pharmaceutical policies. Copyright © 2017 Elsevier B.V. All rights reserved.
