On certain curves of genus three in characteristic two

We study curves of genus 3 over algebraically closed fields of characteristic 2 with the canonical theta characteristic totally supported in one point. We compute the moduli dimension of such curves and focus on some of them which have two Weierstrass points with Weierstrass directions towards the support of the theta characteristic. We answer questions related to order sequence and Weierstrass weight of Weierstrass points and the existence of other Weierstrass points with similar properties.

Obsessive-compulsive disorder and personality disorder - Evidence from the British National Survey of Psychiatric Morbidity 2000

Background Previous studies indicate that most individuals with obsessive-compulsive disorder (OCD) have comorbid personality disorders (PDs), particularly from the anxious cluster. However, the nature and strength of this association remains unclear, as the majority of previous studies have relied heavily on clinical populations. We analysed the prevalence of screen positive personality disorder in a representative sample of adults with OCD living in private households in the UK. Methods A secondary analysis of data from the 2000 British National Survey of Psychiatric Morbidity. The prevalence of PD, as determined by the SCID-II questionnaire, was compared in participants with OCD, with other neuroses and non-neurotic controls. Within the OCD group we also analysed possible differences relating to sex and subtypes of the disorder. Results the prevalence of any screen positive PD in the OCD group (N = 108) was 74%, significantly greater than in both control groups. The most common screen positive categories were paranoid, obsessive-compulsive, avoidant, schizoid and schizotypal. Compared to participants with other neuroses, OCD cases were more likely to screen positively for paranoid, avoidant, schizotypal, dependent and narcissistic PDs. Men with OCD were more likely to screen positively for PDs in general, cluster A PDs, antisocial, obsessive-compulsive and narcissistic categories. The presence of comorbid neuroses in people with OCD had no significant effect on the prevalence of PD. Conclusions Personality pathology is highly prevalent among people with OCD who are living in the community and should be routinely assessed, as it may affect help-seeking behaviour and response to treatment.

Effect of combined bending strain and thermal cycling on the voltage-current characteristic curves of Bi-2223 tapes

High critical temperature superconductors are evolving from a scientific research subject into large-scale application devices. In order to meet this development demand they must withstand high current capacity under mechanical loads arising from thermal contraction during cooling from room temperature down to operating temperature (usually 77 K) and due to the electromagnetic forces generated by the current and the induced magnetic field. Among the HTS materials, the Bi2Sr2Ca2Cu3Ox, compound imbedded in an Ag/AgMg sheath has shown the best results in terms of critical current at 77 K and tolerance against mechanical strain. Aiming to evaluate the influence of thermal stress induced by a number of thermal shock cycles we have evaluated the V-I characteristic curves of samples mounted onto semicircular holders with different curvature radius (9.75 to 44.5 mm). The most deformed sample (epsilon = 1.08%) showed the largest reduction of critical current (40%) compared to the undeformed sample and the highest sensitivity to thermal stress (I-c/I-c0 = 0.5). The V-I characteristic curves were also fitted by a potential curve displaying n-exponents varying from 20 down to 10 between the initial and last thermal shock cycle.

Synaptonemal polycomplexes in spermatids: a characteristic trait of Orthoptera?

Spermatogenesis was analysed in a cricket, Eneoptera surinamensis (Gryllidae, Orthoptera), using ultrathin serial sections and transmission electron microscopy. Special attention was placed on documentation of the development and structure of synaptonemal polycomplexes (PCs) within spermatid nuclei. Pachytene spermatocytes showed the usual tripartite synaptonemal complexes in the nuclear lumen. PCs were situated close to chromosomes at the periphery of spindles in prometaphase I spermatocytes, where microtubule density was low. The PCs are probably incorporated into the daughter nuclei of both meiotic divisions by adhesion to chromosomes. Finally, PCs end up within spermatid nuclei. Analysis of serial sections through three nuclei of young spermatids revealed at least one PC within each. The PCs were intimately attached to an electrondense spherical nuclear body. This topographical correlation was confirmed through inspection of random sections. The PCs may have an affinity to the spherical bodies. In more developed spermatids, PCs and nuclear bodies were missing. Disassembly products of the PCs may play a role in spermatid maturation. In a series of other Orthoptera species, PCs have been reported to occur in the cytoplasm or the nuclei of spermatids. In most other systematic groups, PCs do not form at all or disassemble earlier. The presence of PCs in young spermatids, therefore, seems to be typical of Orthoptera.

Comorbidity of obsessive-compulsive disorder and personality disorders. A Brazilian controlled study

The aim of this study was to evaluate the presence of personality disorders (PDs) in 40 patients with obsessive-compulsive disorder (DSM-III-R criteria) from the Medical School of Botucatu (UNESP), Sao Paulo, Brazil. It is a case-control study. Patients were 24 women and 16 men, 16-68 years old, referred to our outpatient psychiatric service for treatment. Controls were 40 nonpsychiatric outpatients matched to the cases by sex, age and marital status. The instrument used was the Portuguese version of the Structured Interview for DSM-III-R Personality Disorders (SIDP-R). All interviews (n = 80) were made simultaneously by 2 raters, with independent scoring, so that the interrater reliability of the instrument could also be assessed (kappa statistics). The consensual axis II diagnoses in the OCD group were: avoidant (52.5%, κ = 0.80), dependent (40%, κ = 0.84), histrionic (20%, κ = 0.83), paranoid (20%, κ = 0.74), obsessive-compulsive (17.5%, κ = 0.86), narcissistic (7.5%, κ = 1.00), schizotypal (5%, κ = 0.65), passive-aggressive (5%, κ = 0.79) and self-defeating (5%, κ 0.55). At least one PD diagnosis was made in 70% of the patients, while only 6 controls had a PD diagnosis (p < 0.01). A great deal of diagnostic overlap was found in the OCD group (57.5% had two or more PDs), especially between avoidant and dependent PDs. The features of these two PDs may be secondary to the OCD. The study also suggests that there is not a close relationship between OCD and obsessive-compulsive personality disorder (OCPD). Patients with OCPD or even 3 or 4 O-C traits had significantly less insight into their obsessions and compulsions (p < 0.01).

FTMOntology: An ontology to fill the semantic gap between music, mood, personality, and human physiology

This paper presents a domain ontology, the FeelingTheMusic Ontology - FTMOntology. FTMOntology is designed to represent the complex domain of music and how it relates to other domains like mood, personality and physiology. This includes representing the main concepts and relations of music domain with each of the above-mentioned domains. The concepts and relations between music, mood, personality and physiology. The main contribution of this work is to model and relate these different domains in a consistent ontology. © 2011 Springer-Verlag.

Identificando tipos de personalidade na dança de salão

Many studies have shown a variety of benefits that the practice of Ballroom Dancing can bring, such as leisure and entertainment, the release of tension from a stressful routine, improving relationships, expanding social contacts. The rationale of this study is by the need to evaluate a different sphere of life of people involving the structure that is the personality. The man is humanized in contact with other men and the culture it is almost impossible to grow it in isolation, that is, are the social relationships that allow men to become human and her personality structure. The relationship brought about by the ballroom dancing can benefit the development of personality or simply put individuals in situations that provide a greater understanding of yourself, as this activity has characteristics that greatly facilitate social contact between people who practice it as the relationship between gentleman and lady for a dance, the contact with people in different classes, social events where it is practiced and even the music that is danced. This work aimed to be able to identify the type or types, the most common personalities exist in one group of participants in a course of Ballroom, based on the technique of Enneagram developed and disseminated by Gurdjieff, whose characteristic is to divide into nine different personality types. Participants were 42 students of the extent to ballroom dancing. We administered a questionnaire to identify the personality of each participant and then there was a second observation time the behavior of six participants in the class for confirmation of your psychological type to issofoi used a checklist developed by the author. Was also investigated whether there are differences of gender and psychological types who seek more such activity. The conclusions are that there are a large number of persons type 9, more than 42% and are predominantly male, since... (Complete abstract click electronic access below)
