Since psychiatry for a long time has abandoned inhuman ways of imaginary treatment and replaced them with humane compassion and attention to a sick soul, science does not get tired of finding means against mental illnesses. At the present time, the question of bed rest is being interpreted quite energetically with mental suffering.

Child schizophrenia is a mental disorder that affects brain structures, emotional and cognitive functions. The disorder is characterized by psychotic symptoms: disorder of thinking, inadequate emotional reactions, disorganized behavior, deterioration of social functioning and loss of will. Schizophrenia in children is one of the most common mental illnesses affecting up to 1% of all children. For a long time, the term "child schizophrenia" was used to refer to various disorders that had similarities with each other. Children were referred to schizophrenics if they had borderline symptoms. Child schizophrenia develops gradually; sudden onset it is not common. Schizophrenic child requires help from multidisciplinary team members including child and adolescent psychiatrist and all possible levels of psychotherapy and psychological interventions. This article discusses classification, clinical presentation, all possible treatment and rehabilitation of children with schizophrenia.

Talking Cure

It would seem that a disorder as complex as a mental illness would require equally complex solutions. “Talking cures”, known today as psychotherapies, were lauded as unscientific for a very long time.1 Today, cognitive behaviour therapy (CBT) is a psychotherapeutic technique that has shown considerable success in improving the prognosis for many mental illnesses using the scientific method. It is considered a panacea by some for mental illness amidst the zeitgeist of skepticism for pharmacology. This article explores the philosophical foundations of CBT and explains how a technique considered as unscientific is now the gold-standard in mental illness treatment. A randomized controlled trial (RCT) will also be discussed to examine its validity on psychotherapy and determine whether efficiency studies may be more suitable to adequately compare psychotherapies.

The Impact

INTRODUCTION: Burden on informal carers of people with mental or physical illnesses has been studied for a long time. Several standardized instruments for the assessment of carer's burden have been developed. The Burden Interview is one of the most frequently used instruments. The aim of the present study is to examine the internal consistency and validity of the Brazilian version of the Burden Interview, designed to examine the burden in carers of individuals with mental illnesses. METHODS: Carers of patients with a diagnosis of depression, aged 60 or over, were assessed for burden (Burden Interview), emotional distress (SRQ-20) and their perception of patients' behavioral and mood disturbances (Behavioral and Mood Disturbance Scale - BMD). Socio-demographic information of patients and carers was collected with a standardized form. The reliability of the Burden Interview was assessed through its internal consistency. Construct validity was assessed through the exam of the associations of carers' burden with their perception of patients' behavioral and mood disturbances, and the carers' burden with carers' distress. RESULTS: Eighty-two carers of elderly patients with depression were included, being forty-eight (58,5%) women. The internal consistency was good, with a Cronbach's alpha of 0.87. The associations between total scores of the Burden Interview and total scores of the SRQ-20 (r=0.37, p=0.001), and between total scores of the Burden Interview with total scores of BMD (r=0.54, p=0.001) were strong, and similar to other studies that examined those associations, indicating a good construct validity of the Brazilian version of the Burden Interview. DISCUSSION: The Brazilian version of the Burden Interview is a standardized and valid instrument that can be used in the study of the impact of mental and physical illnesses on informal carers.

The Continuum

Temperament of healthy people and mental illnesses, particularly affective disorders, have been conjectured to lie along a continuum of neurobehavioural regulation. Understanding the nature of this continuum may better inform the construction of taxonomies for both categories of behaviour. Both temperament and mental illness refer to patterns of behaviour that manifest over long time scales (weeks to years) and they appear to share many underlying neuroregulatory systems. This continuum is discussed from the perspectives of nonlinear dynamical systems theory, neurobiology and psychiatry as applied to understanding such multiscale time-series behaviour. Particular emphasis is given to issues of generativity, fungibility, metastability, non-stationarity and contextuality. Implications of these dynamical properties for the development of taxonomies will be discussed. Problems with the over-reliance of psychologists on statistical and mathematical methods in deriving their taxonomies (particularly those based on factor analysis) will be discussed from a dynamical perspective. An alternative approach to temperament based upon functionality, and its discriminative capabilities in mental illness, is presented. This article is part of the theme issue ‘Diverse perspectives on diversity: multi-disciplinary approaches to taxonomies of individual differences’.

In recent years, the electron microscope has been significantly improved in resolution and we can obtain routinely atomic-level high resolution images without any special skill. With this improvement, the structure analysis of organic materials has become one of the interesting targets in the biological and polymer crystal fields.Up to now, X-ray structure analysis has been mainly used for such materials. With this method, however, great effort and a long time are required for specimen preparation because of the need for larger crystals. This method can analyze average crystal structure but is insufficient for interpreting it on the atomic or molecular level. The electron microscopic method for organic materials has not only the advantage of specimen preparation but also the capability of providing various information from extremely small specimen regions, using strong interactions between electrons and the substance. On the other hand, however, this strong interaction has a big disadvantage in high radiation damage.

Long Time

For a long time, the development of dynamical theory for HEER has been stagnated for several reasons. Although the Bloch wave method is powerful for the understanding of physical insights of electron diffraction, particularly electron transmission diffraction, it is not readily available for the simulation of various surface imperfection in electron reflection diffraction since it is basically a method for bulk materials and perfect surface. When the multislice method due to Cowley & Moodie is used for electron reflection, the “edge effects” stand firmly in the way of reaching a stationary solution for HEER. The multislice method due to Maksym & Beeby is valid only for an 2-D periodic surface.Now, a method for solving stationary solution of HEER for an arbitrary surface is available, which is called the Edge Patching method in Multislice-Only mode (the EPMO method). The analytical basis for this method can be attributed to two important characters of HEER: 1) 2-D dependence of the wave fields and 2) the Picard iteractionlike character of multislice calculation due to Cowley and Moodie in the Bragg case.

The electron holes confined to the CuO2-plane are the charge carriers in high-temperature superconductors, and thus, the distribution of charge plays a key role in determining their superconducting properties. While it has been known for a long time that in principle, electron diffraction at low angles is very sensitive to charge transfer, we, for the first time, show that under a proper TEM imaging condition, it is possible to directly image charge in crystals with a large unit cell. We apply this new way of studying charge distribution to the technologically important Bi2Sr2Ca1Cu2O8+δ superconductors.Charged particles interact with the electrostatic potential, and thus, for small scattering angles, the incident particle sees a nuclei that is screened by the electron cloud. Hence, the scattering amplitude mainly is determined by the net charge of the ion. Comparing with the high Z neutral Bi atom, we note that the scattering amplitude of the hole or an electron is larger at small scattering angles. This is in stark contrast to the displacements which contribute negligibly to the electron diffraction pattern at small angles because of the short g-vectors.

Intermetallic Matrix Composites

Intermetallic matrix composites are candidates for ultrahigh temperature service when light weight and high temperature strength and stiffness are required. Recent efforts to produce intermetallic matrix composites have focused on the titanium aluminide (TiAl) system with various ceramic reinforcements. In order to optimize the composition and processing of these composites it is necessary to evaluate the range of structures that can be produced in these materials and to identify the characteristics of the optimum structures. Normally, TiAl materials are difficult to process and, thus, examination of a suitable range of structures would not be feasible. However, plasma processing offers a novel method for producing composites from difficult to process component materials. By melting one or more of the component materials in a plasma and controlling deposition onto a cooled substrate, a range of structures can be produced and the method is highly suited to examining experimental composite systems. Moreover, because plasma processing involves rapid melting and very rapid cooling can be induced in the deposited composite, it is expected that processing method can avoid some of the problems, such as interfacial degradation, that are associated with the relatively long time, high temperature exposures that are induced by conventional processing methods.

Specimen support and astigmatism correction in Electron Microscopy are at least two areas in which lacey polymer films find extensive applications. Although their preparation has been studied for a very long time, present techniques still suffer from incomplete release of the film from its substrate and presence of a large number of pseudo holes in the film. Our method ensures complete removal of the entire lacey film from the substrate and fewer pseudo holes by pre-treating the substrate with Gum Arabic, which acts as a film release agent.The method is based on the classical condensation technique for preparing lacey films which is essentially deposition of minute water or ice droplets on the substrate and laying the polymer film over it, so that micro holes are formed corresponding to the droplets. A microscope glass slide (the substrate) is immersed in 2.0% (w/v) aq. CTAB (cetyl trimethyl ammonium bromide)-0.22% (w/v) aq.

Quantitative recording of electron patterns and their rapid conversion into digital information is an outstanding goal which the photoplate fails to solve satisfactorily. For a long time, LLL-TV cameras have been used for EM adjustment but due to their inferior pixel number they were never a real alternative to the photoplate. This situation has changed with the availability of scientific grade slow-scan charged coupled devices (CCD) with pixel numbers exceeding 106, photometric accuracy and, by Peltier cooling, both excellent storage and noise figures previously inaccessible in image detection technology. Again the electron image is converted into a photon image fed to the CCD by some light optical transfer link. Subsequently, some technical solutions are discussed using the detection quantum efficiency (DQE), resolution, pixel number and exposure range as figures of merit.A key quantity is the number of electron-hole pairs released in the CCD sensor by a single primary electron (PE) which can be estimated from the energy deposit ΔE in the scintillator,
