Religious teachings that are part of humanity's heritage are constantly being reinterpreted as reality and social values change. In this process, literature also makes its contribution, questioning some values and revealing its character of imposition and social domination. In this work, we will analyze how this happens in two novels by American writers, Alice Walker's The Purple Color and Bernard Malamud's The Fixer. Coming from different ethnic groups, these writers question the traditional representation of God from the reality of their social group, Walker from the perspective of a black feminist and activist while Malamud does it from the perspective of Judaism. Their questioning will be determined by the injustices their groups suffer as social minorities. In the end, we will see that, despite coming from different social backgrounds, at the root of the questioning of the two writers is the ideal of fighting for freedom itself, which is such a strong value in American culture and society. Thus, this becomes the parameter and measure for questioning secular religious notions in the novels of these authors. Las enseñanzas religiosas que forman parte del patrimonio de la humanidad se reinterpretan constantemente a medida que cambian la realidad y los valores humanos. En este proceso, la literatura también hace su aporte, cuestionando algunos valores y revelando su carácter de imposición y dominación social. En este trabajo analizaremos cómo sucede esto en dos novelas de escritores estadounidenses, El color púrpura de Alice Walker y The Fixer de Bernard Malamud. Procedentes de diferentes etnias, estos escritores cuestionan la representación tradicional de Dios desde la realidad de su grupo social, Walker desde la perspectiva de una feminista y activista negra mientras que Malamud lo hace desde la perspectiva del judaísmo. Su cuestionamiento estará determinado por las injusticias que sufren sus grupos como minorías sociales. Al final, veremos que, a pesar de provenir de diferentes orígenes sociales, en la raíz del cuestionamiento de los dos escritores está el ideal de luchar por la libertad misma, que es un valor tan fuerte en la cultura estadounidense. Así, esto se convierte en el parámetro y medida para cuestionar las nociones religiosas seculares en las novelas de estos autores. Os ensinamentos religiosos que fazem parte da herança da humanidade estão constantemente sendo reinterpretados à medida que a realidade e os valores humanos vão mudando. Nesse processo, a literatura também dá a sua contribuição, questionando alguns valores e revelando o seu caráter de imposição e dominação social. Nesse trabalho, nós vamos analisar como isso acontece em dois romances de escritores norte-americanos, A cor púrpura, de Alice Walker e O bode expiatório (The Fixer), de Bernard Malamud. Sendo oriundos de grupos étnicos diferentes, esses escritores questionam a representação tradicional de Deus a partir da realidade de seu grupo social, Walker da perspectiva de uma feminista e ativista negra enquanto que Malamud o faz da perspectiva do judaísmo. O questionamento deles será determinado pelas injustiças que seus grupos sofrem enquanto minorias sociais. Ao final, veremos que, apesar de virem de meio sociais diferentes, na raiz do questionamento dos dois escritores está o ideal de luta pela própria liberdade que é um valor tão forte na cultura norte-americana. Assim, esse se torna o parâmetro e a medida para se questionar noções religiosas seculares nos romances desses autores.

O objetivo deste trabalho é uma análise da homossocialidade no romance Antes de Adão (1907) do escritor norte-americano Jack London, conhecido, entre outras coisas, pelo seu estilo de tough guy. Para tal, apresentamos primeiramente uma conceituação dessa expressão de masculinidade na sociedade estadunidense e uma rápida discussão do conceito de homossocialidade, concentrando-nos em suas principais características. Baseado nesse conceito, analisamos o relacionamento entre os dois principais personagens masculinos do romance acima citado. Essa análise revela um tipo de homossocialidade entre os dois principais personagens que se caracteriza por um grande companheirismo e também por um erotismo subjacente. Embora não seja um aspecto aprofundado no nosso trabalho, temos oportunidade de constatar que esse é um padrão que se repete em outros romances do escritor norte-americano e reflete seu próprio comportamento, em sua vida social, em relação a seus amigos homens The aim of this work is an analysis of homosociality in the novel Before Adam (1907) by the American writer Jack London, known, among other things, for his tough guy style. To this end, we first present a conceptualization of this expression of masculinity in North-American society and a quick discussion on the concept of homosociality, focusing on its main characteristics. Based on this concept, we analyze the relationship between the two main male characters in the novel mentioned above. This analysis reveals a type of homosociality between the two main characters that is characterized by great companionship and also by an underlying eroticism. Although it is not an in-depth aspect of our work, we have the opportunity to note that this is a pattern that is repeated in other novels by the American writer and reflects his own behavior, in his social life, towards his male friends

Orientador: Dr. Guilherme Souza Cavalcanti de Albuquerque Coorientador: Dr. Armenes de Jesus Ramos Junior Dissertação (mestrado) - Universidade Federal do Paraná, Setor de Ciências da Saúde, Programa de Pós-Graduação em Saúde Coletiva. Defesa : Curitiba, 11/07/2018 Inclui referências: p.148-153 Resumo: presente dissertação objetiva demonstrar as bases socioeconômicas que determinam o surgimento do direito universal à saúde na URSS. Valendo-se de pesquisa bibliográfica foram analisadas três obras que apresentam panoramas acerca da criação e implantação do sistema de saúde soviético, obras estas escritas entre 1933 e 1937, respectivamente por Nikolai Semashko, primeiro comissário de saúde soviético, Arthur Newsholme & John Kingsbury, o primeiro eminente médico inglês e o segundo um filantropo americano e Henry Sigerist, eminente historiador da medicina franco/suíço. Para proceder com a análise das obras destes autores utilizou-se o materialismo histórico dialético com base em Marx e Engels, utilizando as categorias forças produtivas, relações sociais de produção, revolução social e política, mercadoria e salário. Em paralelo se faz uma apresentação das principais mudanças operadas nas constituições russas de 1906, 1917 e 1936, servindo de apoio à coleta de evidências processada nas obras dos referidos autores. Percebeuse na análise das obras que existem evidências materiais que apontam para o surgimento do direito universal à saúde no contexto revolucionário soviético o que permitiu concluir que a saúde gratuita e universal, enquanto nova qualidade de atendimento às necessidades de reprodução social da vida, trata-se de uma decorrência direta do processo de transição entre modos de produção, que se observou na Rússia revolucionada Abstract: The present dissertation aims to demonstrate the socioeconomic bases of the universal right to health emergence in the USSR. The bibliographical studie were carried out on three authors on the creation and implementation of the Soviet health system. These works were written between 1933 and 1937 by Nikolai Semashko, the first Soviet health commissioner, Arthur Newsholme & John Kingsbury, respectively, first eminent English doctor and the second an American philanthropist and Henry Sigerist, eminent French/Swiss historian of medicine. In order to proceed with the analysis of these authors, dialectical historical materialism based on Marx and Engels was used, using the categories of productive forces, social relations of production, social and political revolution, merchandise and wages. In parallel, a presentation is made of the main changes made in the Russian constitutions of 1906, 1917 and 1936, supporting the collection of evidence processed in the works of these authors. It was noticed in the analysis of the works that there is material evidence that points to the emergence of the universal right to health in the Soviet revolutionary context which allowed to conclude that free and universal health, as a new quality of service to the needs of social reproduction of life, is a direct result of the process of transition between modes of production, which was observed in revolutionized Russia

O presente trabalho tem como objetivo principal realizar um estudo de gênero com foco no personagem Santos do romance A Porta e o Vento (1974), do escritor currais-novense José Bezerra Gomes. Metodologicamente, fez-se pesquisa bibliográfica sobre a temática estudada, especialmente de três textos teóricos distintos que juntos ajudam na definição dos valores morais e sociais que regem a vida “cabra macho nordestino”, e cujos autores são Bento (2012), Gikovate (1989) e Albuquerque Júnior (2003). Dessa forma, concluiu-se que no romance estudado o casamento é entendido como um rito de passagem para ser homem por completo, e mesmo que Santos lute contra isso, para sua infelicidade, mais dia menos dia, os ventos gerados pelo brado do “cabra macho” não irão parar de bater na porta de sua casa e adentrarão sua vida. Nesse caso, a porta caracteriza-se como a tentativa de Santos de se proteger daquilo que, quando vem como o vento, atinge a todos e invade os recantos, e nem mesmo a porta fechada consegue detê-lo. No caso específico, são as cobranças e valores dos quais Santos não consegue se defender, nem fugir

Dissertação de mestrado em Contabilidade, A presente investigação tem por objetivo analisar e aferir se os procedimentos utilizados nas auditorias internas (AI) realizadas pelas Inspetorias de Contabilidade e Finanças do Exército (ICFEx) no Sistema de Saúde do Exército Brasileiro (SSEB) estão alinhados com os procedimentos e recomendações preconizados por organismos internacionais da área de AI, em particular pelo Institute of Internal Auditors (IIA), pela Association of Healthcare Internal Auditors (AHIA) e pelo Office of Inspector General the United States Department of Health and Human Services (OIG). O estudo é motivado pelo reduzido número de pesquisas abordando a auditoria em saúde no contexto da administração pública, principalmente no Brasil e no contexto das Forças Armadas Brasileiras – Exército Brasileiro. Além disso, a auditoria em saúde passou a ocupar papel de relevo na administração hospitalar, pois os gastos com os cuidados de saúde já ultrapassam os 10% do Produto Interno Bruto em países desenvolvidos, como Estados Unidos da América, França e Alemanha. Elaborou-se uma revisão de literatura enfocando os princípios da New Public Management, a governança e a accountability no setor público da saúde e a auditoria governamental e sua aplicação à área da saúde. Além disso, foram pesquisados os procedimentos de AI aplicáveis a área da saúde estabelecidos por organismos internacionais, particularmente o IIA, AHIA e OIG. A pesquisa é apoiada no paradigma interpretativo e positivista da investigação, utiliza a abordagem qualitativa e quantitativa do estudo em contabilidade, e é exploratória quanto aos seus fins. Ademais, o método escolhido para estudar o fenômeno foi o estudo de caso na sua modalidade simples. A análise realizada permite concluir que os procedimentos usados pelas ICFEx quando da realização das AI no SSEB estão bastante alinhadas com os procedimentos gerais preconizadas pela IPPF do IIA, pela AHIA e pelo OIG, no que tange aos aspectos básicos da AI e às questões relacionadas com a área não clínica da organização militar de saúde (OMS). Por outro lado, as práticas das ICFEx estão minimamente alinhadas, particularmente com as recomendações da AHIA e com as orientações do OIG, quando se relacionam com os procedimentos a serem efetivados no setor clínico da OMS, no que respeita à avaliação dos controles internos estabelecidos e dos riscos mais relevantes, e em particular, quanto à apreciação dos registros confeccionados pelos profissionais de saúde nos prontuários dos pacientes com as finalidades de verificar a qualidade da assistência prestada e a correção da conta hospitalar. As percepções dos auditores internos das ICFEx revelam que os procedimentos empregados nas AI efetuadas pelas ICFEx no SSEB estão razoavelmente ou mais alinhados com os procedimentos gerais de AI estabelecidos nas componentes da IPPF do IIA que devem regular as atividades de AI, incluindo aquelas desenvolvidas na área da saúde. Contudo, as percepções dos auditores internos das ICFEx revelam que os procedimentos de AI usados pelas ICFEx no SSEB estão minimamente alinhados com as orientações da AHIA e do OIG quando a avaliação foca a área clínica da OMS, e muito alinhados quando a apreciação foca a área administrativa (não clínica) da OMS. Por fim, os auditores internos das ICFEx compreendem que a estrutura de recursos humanos da Seção de Auditoria e Fiscalização das ICFEx não é adequada para efetuar AI abarcando todas as áreas das OMS, e, sobretudo, que as equipes de auditoria não contemplam profissionais com as competências adequadas para analisar e avaliar a área clínica das OMS do EB., The main purpose of this investigation is to analyse and assess whether the procedures used in internal audits (IA) carried out by the Brazilian Army Accounting and Finance Inspection Offices (ICFEx) in the Brazilian Army Healthcare System (SSEB) are in line with the procedures and recommendations established by international organizations in the IA area, in particular by the Institute of Internal Auditors (IIA), the Association of Healthcare Internal Auditors (AHIA) and the Office of Inspector General of the United States Department of Health and Human Services (OIG). The motivation for this study is the scarse investigation on healthcare auditing in the public administration context, namely in Brazil and in the context of the Brazilian Armed Forces - Brazilian Army. In addition, healthcare auditing has come to play a relevant role in the healthcare institutions administration, since healthcare expenditures already exceed 10% of gross domestic product in developed countries, such as the United States, France and Germany. A literature review was developed focusing the principles of New Public Management, governance and accountability in public healthcare sector, and government auditing and its application to healthcare institutions. Additionally, the healthcare audit procedures promoted by international organizations were explored, particularly those promoted by IIA, AHIA and OIG. This research is supported by the interpretative and the positivist paradigm, uses the qualitative and quantitative approaches, and is exploratory as to its purposes. It uses the case study methodology to achieve its main purpose. The analysis performed allows to realize that the AI procedures performed by ICFEx in the SSEB are fairly aligned with the general procedures promoted by the IPPF of the IIA, by the AHIA guidelines and by the OIG recommendations regarding the basic procedures of IA in non-clinical areas of healthcare institutions. Nevertheless, the ICFEx AI practices in SSEB are minimally aligned, particularly with the AHIA recommendations and the OIG guidelines, when they relate to the procedures to be carried out in the clinical area of the Military Healthcare Organizations (OMS), in particular, in the internal controls evaluation and relevant risks assessment, and in evaluating the records prepared by the healthcare professionals in the patients' charts, in order to verify the quality of healthcare services provided and the correction of the hospital's bill. The perceptions of the ICFEx internal auditors point out that the AI procedures of ICFEx in SSEB are reasonably or more in line with the general IA procedures established in the IIA IPPF components that should guide the AI activities, including those developed in the healthcare area. However, the perceptions of ICFEx internal auditors indicate that the AI procedures of ICFEx in SSEB are minimally aligned with the AHIA and OIG guidelines, when the evaluation encompasses the OMS clinical area, but are highly aligned when the assessment is made in the non-clinical area of the OMS. Finally, the ICFEx internal auditors realize that the human resources structure of the ICFEx Audit and Compliance Section is not adequate to carry out an IA covering all the areas of the OMS, and specially, that the audit teams do not contain auditors with the specific competencies that are necessary to evaluate the clinical area of the OMS.

The structure of the isoscalar giant dipole resonance (ISDGR) in 208Pb has been investigated by using the continuum Randon Phase Aproximation (RPA). The main properties (strength function and escape widths) of the ISDGR are calculated and compared with recent available experimental data.

The odd-odd 58 Co nucleus has been studied with the 51 V( 10 B, p2n) reaction at 33 MeV and 36 MeV incident energy using the γ-spectrometer Saci-Perere. Excited states up to 8.0 MeV and spin up to 11 + have been observed. DSAM lifetimes for 13 excited states were measured. The results are compared to shell model calculations using the GXPF1 effective interaction, developed for use in the fp shell.

According to his biographers, W. Somerset Maugham was always careful about not allowing traces of his homosexuality to get into his novels. However, it seems Maugham was not entirely successful in carrying out this decision of his. At least, this is what can be concluded after reading Gore Vidal's Maugham's Half & Half where he points out The Narrow Corner, Maugham's novel published in 1932, as one dealing covertly with the homosexuality theme. Our intention is to conduct a careful analysis of this novel to raise its hidden traces of homosexuality which, in Vidal's view, Maugham is not successful in disguise.

The separation energy and half-life of some heavy proton emitting nuclei, and the single-particle structure of the unbound 11-N, have been evaluated by implementing a careful numerical treatment to solve Schrodinger equation in a continuum discretization context. The basic scheme behind the method consists in using the ground-state proton emitter in connection with an isolated single-particle resonance., 7 pages, 1 figure, 3 tables, RevTex4

A numerical code to evaluate the level density for deformed nuclei based on the semimicroscopical combined method is presented. It includes the use of combinatorial and statistical approaches for low and high energies respectively; both calculations are carried out in the framework of the BCS with the Lipkin–Nogami pairing model.

The influence of low-lying discrete states on the partition function for electron capture and beta decay rates in stellar conditions is discussed. Calculations are carried out for 56 Fe , 57 Fe , 59 Co and 60 Co . Experimental data and different level densities are used. We show that by using a simple but consistent approximation to calculate the nuclear partition function, it is possible to modify significantly the electron capture and beta decay rates.

Precise elastic and inelastic differential cross sections have been measured for the 16 O + 88 Sr , 90,92 Zr, 92 Mo systems at sub-barrier energies. From a coupled channel data analysis, the corresponding “experimental” bare potentials have been determined. The comparison of these potentials with those derived from double-folding theoretical calculations and the high energy (96 Mev/nucleon) elastic scattering data analysis indicate that the method is a very sensitive probe of the ground-state nuclear densities in the surface region.

The proton and neutron decay of the giant monopole resonance in {sup 90}Zr is analyzed in terms of collective and statistical doorway states. For this purpose the hybrid model of the decay is used in the context of channel particle competition. The semidirect components are compatible with the particle-hole continuum random-phase-approximation calculations. The protons spectra are found to be predominantly statistical while the neutron spectra contain semidirect contributions. {copyright} {ital 1997} {ital The American Physical Society}

The proton spectra of the giant quadrupole resonance decay in {sup 40}Ca is analyzed. The decay mechanism of this excitation is studied by the inclusion of the semidirect, preequilibrium, and statistical modes through the chaining evolution of the particle-hole configurations. Strong evidence for the contribution of preequilibrium decay of the giant resonance is established. {copyright} {ital 1997} {ital The American Physical Society}

The odd-odd 58Co nucleus has been studied with the 51V(10B, p2n) reaction at 33-MeV incident energy and the gamma-spectrometer Saci-Pererê. Excited states up to 8.0 MeV and spin up to 11+ have been observed. The results are compared to Shell Model calculations using the GXPF1 effective interaction, developed for use in the fp shell. The pif7/2-1Än(p3/2²f5/2¹) configuration was assigned to the yrast levels.

We have performed quasi-particle calculations for the tin isotopes 119Sn, 121Sn and 123Sn, using realistic effective interactions derived from the Paris and Bonn-A NN potentials. A number-projected one- and three-quasi-particle formalism in the ( g 7 2 , d 5 2 , d 3 2 , s 1 2 , h 11 2 ) model space is employed. We have used a folded-diagram method to derive the corresponding model-space effective interaction, starting from the G-matrix elements derived from the above NN potentials. The G-matrix Pauli-exclusion operator Q 2, specified by the shell-model orbitals (n1, n2, n3) = (11, 21, 36), has been treated accurately. An almost pure ( h 11 2 )3 three-quasiparticle structure for the high spin states from J = 17 2 − to 27 2 − of the above nuclei has been observed. With practically no parameter adjustment, our calculated energies are in very good agreement with available experimental data.

The structure of low-lying states in odd-mass N=83 isotones (135≤A≤151) is investigated in terms of a model in which one neutron-quasiparticle is coupled to quadrupolar and octupolar core-vibrations. Energy levels and spectroscopic factors are calculated and compared with experimental data. Nuclear Structure: 135 Te , 137 Xe , 139 Ba , 141 Ce , 143 Nd , 145 Sm , 147 Gd , 149 Dy , and 151 Er ; calculated levels J, π, and S. Quasiparticle-phonon coupling model.

In a previous paper we showed that an extended Schrodinger equation (ESE) can lead to critical phenomena. The ESE was defined as an integro-differential Schrodinger equation obtained from the traditional differential Schrodinger equation by extending the local potential to a non-local potential. Here we pursue further this procedure by constructing a class of such ESE which is able to generate the (quantum) squeezing phenomenon. As an example, we discuss a model by Glauber for particle trapping by oscillating fields, in the present perspective.

Precise measurements of the elastic and inelastic scattering cross sections for the systems 16 O+ 58,60,62,64 Ni at the sub-barrier energies were made. Coupled-channel analysis were performed. The isotopic dependence of the resulting ion-ion potentials is compared with theoretical calculations using the double-folding method with the M3Y as the nucleon-nucleon interaction and shell-model densities.

In this paper we report the difference between the squeezing effect for quadrature operators (describing a photon field or harmonic oscillator) and for spin variables (describing a two-level system), the distinctions coming from the bound and unbound character of the operators involved in the definition of squeezing for each system.

In this paper, the [Formula: see text] reactions are revisited, with the goal of obtaining spectroscopic factors (SF) for the transition to the ground state of some residual nuclei, applying the distorted wave Born approximation (DWBA). The double-folding São Paulo Potential (SPP) was used to derive the distorted wave function in the entrance and exit channels. The derived SF are compared with the results of extensive shell model calculations showing a rather good agreement.

The structure of low-lying levels in odd-mass Te isotopes (115≤A≤131) is examined in the framework of the projected-quasiparticle-phonon coupling model (PQPC). Effects of particle number symmetry restoration are discussed through the comparison with usual quasiparticle phonon coupling calculations (QPC). Excitation energies, dipole and quadrupole moments are calculated and compared with the experimental data. Nuclear Structure: 115−131 Te ; calculated levels J, π, S, μ, and Q. Number-projected quasiparticle-phonon coupling.

The structure of low-lying levels in odd-mass Te isotopes (115[le][ital A][le]131) is discussed in the framework of the quasiparticle-phonon model. In addition, the properties of [sup 131]Te are also investigated by means of three-particle cluster-phonon coupling, where the pairing force is taken as the residual particle-particle interaction. Excitation energies and spectroscopic factors are calculated and compared with the experimental data.

We implement a reaction-theory based version of the continuum random phase approximation (RPA) approach to the microscopic structure of nuclear giant resonances in its simplest form. This involves a discrete RPA diagonalization of standard size but involving complex matrices so as to account for single-particle resonance widths. Escape widths of individual resonant structures in the case of the giant E1 strength in 16O are obtained in reasonable agreement with available data. The overall strength distribution agrees with that obtained in full continuum RPA calculations.

The description of several physical phenomena may require the solution of a complex eigenvalue problem of a non-Hermitian matrix. This problem may be met in the description of some nuclear and plasmon collective excitations using the linear-response theory. It is shown that there exists a related real matrix which satisfies the usual standard real eigenvalue problem whose solution yields directly the solution of the original problem.

The spreading and escape widths of giant resonances are evaluated by considering damped particle and hole propagation in the nucleus. The magnitude and averaged A-dependence of the isoscalar quadrupole resonance widths are reproduced qualitatively when the nucleon optical potential, fit globally to low-energy scattering, is used to damp nucleon motion. Contributions from hole state widths and from vertex corrections increase and decrease the giant resonance widths, respectively. Qualitative agreement with experimental widths is shown for 16 O , 40 Ca and 208 Pb . Comparison with recent calculations within continuum RPA is made.

The structure of low-lying states in heavy odd-mass N=82 isotones (147\ensuremath{\le}A\ensuremath{\le}153) is investigated in terms of a number-projected one- and three-quasiparticle Tamm-Dancoff approximation. A surface-delta interaction is taken as the residual nucleon-nucleon interaction. Excitation energies, spin, and parity are calculated and compared with the experimental data. Some predictions about dipole and quadrupole moments are presented.

The suppression mechanism on the 0ν- and 2ν-matrix elements is discussed in the framework of a single-mode QRPA model. A multipole expansion of the neutrino potential is performed and the Horie-Sasaki method is employed for the evaluation of radial form factors. The sensitivity to finite nucleon size and short-range correlations is analyzed. It is found that if both corrections are considered simultaneously the net result may not be very different from that the one obtained without any short-range correlation at all. The single-mode model is exemplified by evaluating the 0ν- and 2ν-decay amplitudes for the 48 Ca (0 + )→ 48 Ti (0 + ) transition and a comparison with the experimental data is made.

High-spin states in the odd-odd $^{58}\mathrm{Co}$ nucleus have been studied with the fusion-evaporation reaction $^{51}\mathrm{V}$ ($^{10}\mathrm{B}$,$p2n$) using the \ensuremath{\gamma}-spectrometer Saci-Perere. Thirty-six new excited states up to spin ${11}^{+}$ and an excitation energy of 8.0 MeV have been observed, which are connected by 46 \ensuremath{\gamma}-ray transitions. Transition probabilities for 14 excited states were measured through the Doppler-shift attenuation method. The results are compared with shell-model calculations using the GXPF1 effective interaction, developed for use in the pf shell. These results were interpreted by considering particle-hole excitations with respect to the doubly magic $N=Z=28$ core.

The propagation of the struck proton through the nuclear medium is studied in the semi-classical multicolli-sional internuclear cascade approach. The probability of formation of various residual nucleus configurations and the corresponding excitation energies were obtained as a function of the energy omega transferred to the proton by the knockout.

The decay properties of giant multipole resonances (GMR) are studied using the hybrid model in the context of channel type competition. We found that the analysis of GMR decay with several open channel types has the same analytical expression as when only one channel type is allowed. The generalization of the hybrid model presented provides a simple way to study the competition between the direct and statistical decay of GMR.

We present the result of a theoretical study of inclusive quasi free electrofission of $^{238}$U. The off-shell $ $cross sections for the quasi free reaction stage have been calculated within the Plane Wave Impulse Approximation (PWIA), using a Macroscopic -Microscopic description of the proton and neutron single particle momentum distributions. Electron wave function distortion corrections were included using the effective momentum approximation, and the Final State Interaction (FSI) effects were calculated using an optical potential. The fissility for the proton single hole excited states of the residual nucleus $^{237}$Pa was calculated both without and with contributions of the pre-equilibrium emission of the particles. The fissility for $^{237,238}U$ residual nuclei was calculated within the compound nucleus model. The $(e,e^{\prime}f)-$cross sections thus obtained were compared with available experimental data., 26 pages, 7 figures

The influence of low-lying discrete nuclear states on isotopic abundances in presupernova cores, is discussed. Assuming the hypothesis of nuclear statistical equilibrium (NSE), the Saha equation has been solved for a set of 65 nuclear species (including free protons and neutrons). Experimental data have been used in the calculation of the first terms of the nuclear partition function. The obtained abundances are compared with those evaluated using an energy level density in the computation of the nuclear partition function. We conclude that in future calculations involving isotopic abundances in presupernova cores, the low-lying nuclear states need to be treated as discrete ones when experimental data are available.

We propose an improvement of a Monte Carlo method designed to treat the Ising model in a field [C. Lieu and J. Florencio, J. Low Temp. Phys. 89, 565 (1992)]. The method involves the counting of bonds linking neighboring like-spins and yields the degeneracy of the system's energy states, hence the partition function. There is no acceptance-rejection procedure and all the randomly generated configurations are kept. The sampling depends on geometry only, so results of a given run can be used for all temperatures and energy parameters. In order to understand the virtues and inadequacies of the method, we obtained exact results for small lattices. We find that a Monte Carlo run must be followed by a Gaussian fit in order to account properly for the rare events not recorded in the sampling. Finally, we also established bounds for the location of the peak for the specifc heat of the Ising model in a magnetic field in two dimensions for several values of the field in the thermodynamic limit.

Accuracy and stability of single-particle resonance parameters under changes of a resonance wave function'' are examined in the context of a projection technique. Implications for their use in nuclear structure calculations are discussed.

A hybrid random-phase-approximation--cluster model is developed and applied to the calculation of the dipole response of $^{11}\mathrm{Li}$. A strong collective state at 1.81 MeV is found. Its width is predicted to be \ensuremath{\approxeq}4.0 MeV. The electromagnetic excitation cross section was found to be 700 mb for $^{11}\mathrm{Li}$${+}^{208}$Pb (E=800 MeV/nucleon), close to the experimental result.

Microscopic Combinatorial approach is used to calculate the state and level densities with fixed exciton numbers, in some actinide nuclei. Deformed Saxon-Woods shell model was used as a basis from which all posible configurations were generated. The pairing interaction was taken into account by applying the BCS theory to each configurations. Both the spin and parity distributions were obtained,considering the deformation of the nucleus. Relevance of the result to parity nonconservation studies involving epithermal neutrons on $^{238}$U and $^{232}$Th is discussed., Comment: 22 pages, 7 figures

The structure of low-lying states in odd-mass N=82 isotones (135\ensuremath{\le}A\ensuremath{\le}145) is investigated in terms of a number-projected one- and three-quasiparticles Tamm-Dancoff approximation. A surface-delta interaction is taken as the residual nucleon-nucleon interaction. Excitation energies, dipole and quadrupole moments, and B(M1) and B(E2) values are calculated and compared with the experimental data.

A detailed study of the results of correcting BCS approximation for the effects of particle-number projection and blocking has been carried out. A low-seniority shell-model approximation was used as the frame of reference for investigating the mixing of one- and three-quasiparticle states in odd-mass Ni isotopes and in odd-mass N = 82 isotones. We discuss the results obtained for the energy spectra and electromagnetic decay properties. Effects of seniority-five configurations on the low-lying states have also been studied through the comparison of the low-seniority shell-model results with those which arose from the corresponding full shell-model calculations.
