Psychological factors predicting violent prison inmates' anger and aggression

Based on a functional analysis of aggressive behavior, the present study investigates the psychological determinants of state anger and aggression in violent prison inmates. Comparing psychiatric forensic inpatients with violent prison inmates revealed considerable overlap in these determinants between both samples. Next, the personality traits of neuroticism, agreeableness, conscientiousness, hostility, and anger were studied in explaining the violent prison inmates’ state anger and aggression. Data were obtained from 102 male inmates prisoned for four years or more because of a serious violent crime. Linear regression models were used to assess the relationship between the patients’ characteristics of anger and aggression. It was found that neuroticism, trait anger, and hostility contributed to state anger. Furthermore, the main factor contributing to aggression was state anger. Implications of the results for reducing anger and aggression in violent prison inmates are discussed

Powder-in-Tube (PIT) Nb3Sn conductors for high-field magnets

New Nb3Sn conductors, based on the powder-in-tube (PIT) process, have been developed for application in accelerator magnets and high-field solenoids. For application in accelerator magnets, SMI has developed a binary 504 filament PIT conductor by optimizing the manufacturing process and adjustment of the conductor lay-out. It uniquely combines a non-copper current density of 2680 A/mm2@10 T with an effective filament diameter of about 20 ¿m. This binary conductor may be used in a 10 T, wide bore model separator dipole magnet for the LHC, which is being developed by a collaboration of the University of Twente and CERN. A ternary (Nb/7.5wt%Ta)3Sn conductor containing 37 filaments is particularly suited for application in extremely high-field superconducting solenoids. This wire features a copper content of 43%, a non-copper current density of 217 A/mm2@20 T and a Bc2 of 25.6 T. The main issues and the experimental results of the development program of PIT Nb3Sn conductors are presented and discussed in this pape

Progress in the development of Nb3Sn conductors based on the "Powder in tube" method with finer filaments

Inspired by the successful operation of the 11 T Nb3Sn experimental dipole magnet MSUT, a new large bore 10 [email protected] K Nb3 Sn model dipole magnet is under development in The Netherlands. For application in this system, Shape Metal Innovation (SMI) has developed a new "Powder in tube" type of Nb3Sn conductor with an increased number of filaments. At a strand diameter of 0.9 mm, the diameter of the filaments after reaction for only 33 hours at 675°C has been reduced to about 20 microns. The non-copper critical current density has been measured to be as high as 1890 A/mm 2 at 10 [email protected] K

Treballs Finals de Grau de Belles Arts. Facultat de Belles Arts. Universitat de Barcelona, Curs: 2022-2023, Tutor: Padilla, Òscar[spa] A partir de la observación de las obras de construcción que habitan la ciudad, el proyecto pone en cuestión el uso real de estos espacios, la funcionalidad, la relación constante con la norma, la utilidad o la falta de ella y la intersección con el sujeto, objeto y materia. Espacios de proceso –y pausa– ante el crecimiento de la propia ciudad. Crecimiento urbano que se ha ido conformando de forma gradual y compactada, dejando espacios intermedios que han propiciado la ruptura definitiva o temporal de los límites de la ciudad. Espacios provisionales y procesuales que pasan desapercibidos por su propia condición temporal. Aparentemente de manera dispersa, intento recoger fragmentos para poner en diálogo los encuentros y la interrelación entre espacio, arquitectura, obras de construcción, objetos y materia. A partir del juego entre la función y el proceso arquitectónico y de construcción se pretende subvertir los elementos en relación al propio espacio desde una horizontalidad entre espacio-sujeto-objeto.[eng] Based on the observation of the construction works that inhabit the city, the project questions the real use of these spaces, functionality, the constant relationship with norms, utility or lack thereof, and the intersection with subject, object, and matter. Spaces of process - and pause - in the face of the city’s own growth. Urban growth that has gradually and compactly taken shape, leaving intermediate spaces that have led to the definitive or temporary rupture of the city’s boundaries. Provisional and procedural spaces that go unnoticed due to their temporary condition. Seemingly in a scattered manner, I attempt to collect fragments to bring together the encounters and interrelation between space, architecture, construction works, objects, and matter. Through the interplay between function and architectural and construction processes, the aim is to subvert the elements in relation to the space itself, from a horizontality between space-subject-object

The osteology of the cranial and facial bones of the savannah buffalo Syncerus caffer caffer (Sparrman, 1779)

Zoologists classify the savannah buffalo under the Bovini Tribe. Osteologically, the skull differs from that of the water buffalo of Asia, inter alia, in that the vomer does not articulate with the palatine part of the osseus palate. This gross anatomical study gives a detailed description of all the bones of the skull, mandible and hyoid apparatus of the savannah buffalo Syncerus caffer caffer (Sparrman, 1779). These bones are similar in many respects to that of the domestic bovine. However, due to the robustness of the buffalo skull, many aspects pertaining to bones or parts of bones that are different or more pronounced, are of anatomical importance. The sum-total effect of all these features, gives the skull its typical macro-morphology that differentiates it clearly from the other genera in the Bovini Tribe. The more important characteristics that were found, are the following: 1. The skull of young animals retains basic embryonic reshaping potential till quite late in life. It can be seen as a remnant of Meckel's cartilage in the mandible as well as in prolonged remodelling in the regions of the orbit, dorsum of the nose, and most markedly, also in the lateral walls of the cranium. A subsequent temporary atypical fontanel can even leave an osseus scar in the temporal region. 2. Temporary canals, associated with the developing permanent premolars, appear in the maxilla and mandible. 3. A well defined biomechanical supporting pillar forms internally in the skull of the buffalo. It conveys pressure from the lingual side of the caudal molar alveoli, to the ipsilateral external lamina of the frontal bone in the region of the frontal fossa. 4. Apart from one small external segment, fusion of the perpendicular and basal plates of the ethmoid bone to the presphenoid bone, in the region of the orbital plate, makes ethmoid-related sutures the least visible sutures to see in all post-natal stages. 5. The retro-orbital position of the cornual process, and the presence of a nasoincisive suture, are some of the osteological features that are shared with the domestic goat. 6. Pneumatization of the nasal bone and dorsal concha may occur, as well as of the tympanic part of the temporal bone. 7. The detail of the sutures other than those of the ethmoid bone, may allow "fingerprint" identification of specific bones or complete skulls. Other applied aspects of the skull may be of importance to hunters and clinicians.Thesis (PhD)--University of Pretoria, 2002.Anatomy and Physiologyunrestricte

Breathing exercises for dysfunctional breathing/hyperventilation syndrome in adults

Copyright © 2013 The Cochrane Collaboration. Published by JohnWiley & Sons, Ltd.Background: Dysfunctional breathing/hyperventilation syndrome (DB/HVS) is a respiratory disorder, psychologically or physiologically based, involving breathing too deeply and/or too rapidly (hyperventilation) or erratic breathing interspersed with breath-holding or sighing (DB). DB/HVS can result in significant patient morbidity and an array of symptoms including breathlessness, chest tightness, dizziness, tremor and paraesthesia.DB/HVS has an estimated prevalence of 9.5%in the general adult population, however, there is little consensus regarding the most effective management of this patient group. Objectives: 1) To determine whether breathing exercises in patients with DB/HVS have beneficial effects as measured by quality of life indices. 2) To determine whether there are any adverse effects of breathing exercises in patients with DB/HVS Search methods: We identified trials for consideration using both electronic and manual search strategies. We searched CENTRAL, MEDLINE, EMBASE, and four other databases. The latest search was in February 2013. Selection criteria: We planned to include randomised, quasi-randomised or cluster randomised controlled trials (RCTs) in which breathing exercises, or a combined intervention including breathing exercises as a key component, were compared with either no treatment or another therapy that did not include breathing exercises in patients with DB/HVS. Observational studies, case studies and studies utilising a cross-over design were not eligible for inclusion. We considered any type of breathing exercise for inclusion in this review, such as breathing control, diaphragmatic breathing, yoga breathing, Buteyko breathing, biofeedback-guided breathingmodification, yawn/sigh suppression. Programs where exercises were either supervised or unsupervised were eligible as were relaxation techniques and acute-episode management, as long as it was clear that breathing exercises were a key component of the intervention. We excluded any intervention without breathing exercises or where breathing exercises were not key to the intervention

Wavelength and energy-dispersive X-ray microanalysis with EMA and SEM-EDXRA on thin sections of soils.

Organic matter, minerals and iron-manganese nodules were studied in thin sections of soils with an electron microprobe analyzer (EMA) and a combination of a scanning electron microscope (SEM) and an energy-dispersive X-ray analyzer (EDXRA). Both instruments were used to estimate the presence and nature of chemical elements in two selected areas, one containing a combination of organic and mineral material and another inside an iron-manganese nodule. The detection of organic matter proved problematic. Of the light elements, N could not be detected with EMA and O was detected but was not specific to organic matter. EMA could not be used for C because of the C coating of the thin section. SEM-EDXRA only detected heavier elements. EMA produced somewhat better X-ray images of heavier elements, especially from an iron-manganese nodule. However, with organic material, SEM-EDXRA X-ray images were similar to or slightly better than EMA. An advantage of SEM-EDXRA over EMA is that the soil material can be analysed at various magnifications with a much higher limit, and point analysis can be made of loose material. For soil material, SEM-EDXRA was better as a routine instrument which solved most problems. EMA can be used as a complementary instrument. Other microanalytical techniques such as the ion microprobe mass analyzer (IMMA) were necessary to analyse light elements in organic material of soils.
