Balint groups are now mandatory for psychiatry trainees. Balint groups have been in existence in General Practice for several decades. Providing Balint groups for Psychiatry Non Consultant Hospital Doctors brings with it challenges for the group leader and participants. Many of these challenges are common place in any form of group work, while others are unique to this cohort. This article describes these challenges. Guidelines which offer the the group the best chance of success, in the face of these common challenges, are discussed.

Biochemistry contents are essentials to understanding brewing and students often fail to connect theory with practical applications, in this context, the discipline Beer Science was created, complimenting students` formation. The objective was to integrate the knowledge of biochemistry in beer production and evaluate the students' perception of importance of these. The discipline was given in 2017 and 2018, 24 students per class, with the prerequisite being Biochemistry approval. A didactic sequence was created, starting from the historical aspects and ending with a real beer production. Mains concepts: ph and buffer system; carbohydrates, proteins and lipids in the malt; hops oils/composition; malt and yeast enzymes; fermentative metabolism etc. A questionnaire was applied at the end of the course, evaluating students' perceptions about it, in addition, they delivered a group work simulating a production. Besides the lectures and exercises, 7 practical classes were created, involving the supplies characteristics, mashing buffer effect, temperature and pH effect on the mashing enzymes. There were 31 responses and the students felt very motivated and all considered the biochemical knowledges vital for brewing understanding, attributing greater importance to enzymes and fermentations knowledges, sequentially, to pH, buffer and carbohydrates structure and metabolism. The students emphasized the role of practical classes in order to establish the connections between biochemistry theory and beer production, highlighting the mashing comparison from a matrix of two pH and three temperatures, evaluating the starch hydrolysis with lugol, the amount of fermentable substrate by benedict reaction, and the density by light refractometer. The simulations evaluation indicated that practically all groups were able to apply theoretical knowledge. It is noteworthy that most students felt capable of brewing beer. Disciplines like this are fundamental for the connection between biochemical knowledge and practical applications, such as brewing, especially when developing practices that make this integration possible.

Researchers claim that when students work together in small groups in the language classroom, a single student often emerges as a group leader and that teachers should construct groups based on roles adopted by students. This advice is based on the assumptions that leaders emerge and that teachers can identify leaders in their own classrooms. This paper reports on research that empirically tested these assumptions. Students working in small, fixed groups rated their group members based on perceived leadership. The teacher was responsible for identifying the leader in each group. Individual difference variables of English proficiency, extroversion, and English-speaking self-efficacy (SE) were used to predict emergent leadership. In most groups clear leaders emerged, but the teacher accurately identified the leader in only half of the cases. The findings suggest that teachers should regularly vary group membership and be cautious when assigning roles within groups. 語学の授業において、学生が少人数のグループで活動していると、リーダーが一人現れることがしばしばある、ということが研究者により指摘されている。そして教師は学生それぞれの役割に基づいてグループを作るべきであるという提案がなされている。これは、授業において現れるリーダーを教師は特定できるという想定に基づいている。本稿では、これらの想定を実践的に検証した研究について述べる。固定メンバーの小グループで活動を行う学生たちが、自分の考えるリーダーシップに基づいて自分のグループのメンバーを評価した。また、教師も各グループのリーダーを特定した。グループ内で現れるリーダーを予測するために、英語能力、外向性、英語スピーキングの自己効力感、という個人差が使用された。ほとんどのグループで明確なリーダーが現れたが、教師がそのリーダーを正確に特定できたのは、クラス全体の半分にすぎなかった。検証の結果、グループメンバーを定期的に入れ替えるべきである事と、グループ内で役割を決めるときには十分に注意が必要だと言うことが分かった。 Keywords: emergent leaders; group work; pedagogy; TBLT

When an energetic ion penetrates through an interface between a thin film (of species A) and a substrate (of species B), ion induced atomic mixing may result in an intermixed region (which contains A and B) near the interface. Most ion beam mixing experiments have been directed toward metal-silicon systems, silicide phases are generally obtained, and they are the same as those formed by thermal treatment.Recent emergence of silicide compound as contact material in silicon microelectronic devices is mainly due to the superiority of the silicide-silicon interface in terms of uniformity and thermal stability. It is of great interest to understand the kinetics of the interfacial reactions to provide insights into the nature of ion beam-solid interactions as well as to explore its practical applications in device technology.About 500 Å thick molybdenum was chemical vapor deposited in hydrogen ambient on (001) n-type silicon wafer with substrate temperature maintained at 650-700°C. Samples were supplied by D. M. Brown of General Electric Research & Development Laboratory, Schenectady, NY.

High Voltage Generator

Ultra high voltage STEM has many inherent technical advantages over CTEM. These advantages include better signal detectability and signal processing capability. It is hoped that it will explore some new applications which were previously not possible. Conventional STEM (including CTEM with STEM attachment), however, has been unable to provide these inherent advantages due to insufficient performance and engineering problems. Recently we have developed a new 1250 kV STEM and completed installation at Nagoya University in Japan. It has been designed to break through conventional engineering limitations and bring about theoretical advantage in practical applications.In the design of this instrument, we exercised maximum care in providing a stable electron probe. A high voltage generator and an accelerator are housed in two separate pressure vessels and they are connected with a high voltage resistor cable.(Fig. 1) This design minimized induction generated from the high voltage generator, which is a high frequency Cockcroft-Walton type, being transmitted to the electron probe.

The identification of extraneous phases is important in understanding of high Tc superconducting oxides. The spectroscopic techniques commonly used in determining the origin of superconductivity (such as RAMAN, XPS, AES, and EXAFS) are surface-sensitive. Hence a grain boundary phase several nanometers thick could produce irrelevant spectroscopic results and cause erroneous conclusions. The intergranular phases present a major technological consideration for practical applications. In this communication we report the identification of a Cu2O grain boundary phase which forms during the sintering of YBa2Cu3O7-x (1:2:3 compound).Samples are prepared using a mixture of Y2O3. CuO, and BaO2 powders dispersed in ethanol for complete mixing. The pellets pressed at 20,000 psi are heated to 950°C at a rate of 5°C per min, held for 1 hr, and cooled at 1°C per min to room temperature. The samples show a Tc of 91K with a transition width of 2K. In order to prevent damage, a low temperature stage is used in milling to prepare thin foils which are then observed, using a liquid nitrogen holder, in a Philips 430T at 300 kV.

The term ultimate resolution or resolving power is the very best performance that can be obtained from a scanning electron microscope (SEM) given the optimum instrumental conditions and sample. However, as it relates to SEM users, the conventional definitions of this figure are ambiguous. The numbers quoted for the resolution of an instrument are not only theoretically derived, but are also verified through the direct measurement of images on micrographs. However, the samples commonly used for this purpose are specifically optimized for the measurement of instrument resolution and are most often not typical of the sample used in practical applications.SEM RESOLUTION. Some instruments resolve better than others either due to engineering design or other reasons. There is no definitively accurate definition of how to quantify instrument resolution and its measurement in the SEM.

Nanometer period Ru/C multilayers are one of the prime candidates for normal incident reflecting mirrors at wavelengths < 10 nm. Superior performance, which requires uniform layers and smooth interfaces, and high stability of the layered structure under thermal loadings are some of the demands in practical applications. Previous studies however show that the Ru layers in the 2 nm period Ru/C multilayer agglomerate upon moderate annealing, and the layered structure is no longer retained. This agglomeration and crystallization of the Ru layers upon annealing to form almost spherical crystallites is a result of the reduction of surface or interfacial energy from die amorphous high energy non-equilibrium state of the as-prepared sample dirough diffusive arrangements of the atoms. Proposed models for mechanism of thin film agglomeration include one analogous to Rayleigh instability, and grain boundary grooving in polycrystalline films. These models however are not necessarily appropriate to explain for the agglomeration in the sub-nanometer amorphous Ru layers in Ru/C multilayers. The Ru-C phase diagram shows a wide miscible gap, which indicates the preference of phase separation between these two materials and provides an additional driving force for agglomeration. In this paper, we study the evolution of the microstructures and layered structure via in-situ Transmission Electron Microscopy (TEM), and attempt to determine the order of occurence of agglomeration and crystallization in the Ru layers by observing the diffraction patterns.

Operational Modes

The HB5 STEM instrument at ASU has been modified previously to include an efficient two-dimensional detector incorporating an optical analyser device and also a digital system for the recording of multiple images. The detector system was built to explore a wide range of possibilities including in-line electron holography, the observation and recording of diffraction patterns from very small specimen regions (having diameters as small as 3Å) and the formation of both bright field and dark field images by detection of various portions of the diffraction pattern. Experience in the use of this system has shown that sane of its capabilities are unique and valuable. For other purposes it appears that, while the principles of the operational modes may be verified, the practical applications are limited by the details of the initial design.
